The ServiceWorker will redirect navigation requests that don't match any
`asset` or `data` group to the specified index file. The rules for a
request to be classified as a navigation request are as follows:
1. Its `mode` must be `navigation`.
2. It must accept a `text/html` response.
3. Its URL must match certain criteria (see below).
By default, a navigation request can have any URL except for:
1. URLs containing `__`.
2. URLs to files (i.e. containing a file extension in the last path
segment).
While these rules are fine in many cases, sometimes it is desirable to
configure different rules for the URLs of navigation requests (e.g.
ignore specific URLs and pass them through to the server).
This commit adds support for specifying an optional `navigationUrls`
list in `ngsw-config.json`, which contains URLs or simple globs
(currently only recognizing `!`, `*` and `**`).
Only requests whose URLs match any of the positive URLs/patterns and
none of the negative ones (i.e. URLs/patterns starting with `!`) will be
considered navigation requests (and handled accordingly by the SW).

To ensure that the public API was correctly tagged, the `ts-api-guardian`

a constructor may wish to call inject() directly.
* If an NgModuleFactory is .create()'d twice, and an ngInjectableDef
token is requested from each of them, the second time will fail.
This is because the first injection adds the provider definition
and calls the factory, and the provider definitions are shared.
The second injector will see the provider definition and call the
factory to create an instance, but without setting the correct

Support for using the `ngModel` input property and `ngModelChange`
event with reactive form directives has been deprecated in
Angular v6 and will be removed in Angular v7.
Now deprecated:
```html
<input [formControl]="control" [(ngModel)]="value">
```
```ts
this.value = 'some value';
```
This has been deprecated for a few reasons. First, developers have
found this pattern confusing. It seems like the actual `ngModel`
directive is being used, but in fact it's an input/output property
named `ngModel` on the reactive form directive that simply approximates
(some of) its behavior. Specifically, it allows getting/setting the
value and intercepting value events. However, some of `ngModel`'s other
features - like delaying updates with`ngModelOptions` or exporting the
directive - simply don't work, which has understandably caused some
confusion.
In addition, this pattern mixes template-driven and reactive forms
strategies, which we generally don't recommend because it doesn't take
advantage of the full benefits of either strategy. Setting the value in
the template violates the template-agnostic principles behind reactive
forms, whereas adding a FormControl/FormGroup layer in the class removes
the convenience of defining forms in the template.
To update your code before v7, you'll want to decide whether to stick
with reactive form directives (and get/set values using reactive forms
patterns) or switch over to template-driven directives.
After (choice 1 - use reactive forms):
```html
<input [formControl]="control">
```
```ts
this.control.setValue('some value');
```
After (choice 2 - use template-driven forms):
```html
<input [(ngModel)]="value">

```ts
this.value = 'some value';

Alternatively, you can choose to surface a separate warning for each

This change brings Angular largely in line with how AngularJS previously serialized URLs. This is based on RFC 3986 and resolves issues such as the above #10280 where URLs could be parsed, re-serialized, then parsed again producing a different result on the second parsing.
Adjustments to be aware of in this commit:
* URI fragments will now serialize the same as query strings
* In the URI path or segments (portion prior to query string and/or fragment), the plus sign (`+`) and ampersand (`&`) will appear decoded
* In the URL path or segments, parentheses values (`(` and `)`) will now appear percent encoded as `%28` and `%29` respectively
* In the URL path or segments, semicolons will be encoded in their percent encoding `%3B`
NOTE: Parentheses and semicolons denoting auxillary routes or matrix params will still appear in their decoded form -- only parentheses and semicolons used as values in a segment or key/value pair for matrix params will be encoded.
While these changes are not considered breaking because applications should be decoding URLs and key/value pairs, it is possible that some unit tests will break if comparing hard-coded URLs in tests since that hard coded string will represent the old encoding. Therefore we are releasing this fix in the upcoming Angular v6 rather than adding it to a patch for v5.

This commit bundles 3 important changes, with the goal of enabling tree-shaking
of services which are never injected. Ordinarily, this tree-shaking is prevented
by the existence of a hard dependency on the service by the module in which it
is declared.
Firstly, @Injectable() is modified to accept a 'scope' parameter, which points
to an @NgModule(). This reverses the dependency edge, permitting the module to
not depend on the service which it "provides".
Secondly, the runtime is modified to understand the new relationship created
above. When a module receives a request to inject a token, and cannot find that
token in its list of providers, it will then look at the token for a special
ngInjectableDef field which indicates which module the token is scoped to. If
that module happens to be in the injector, it will behave as if the token
itself was in the injector to begin with.
Thirdly, the compiler is modified to read the @Injectable() metadata and to
generate the special ngInjectableDef field as part of TS compilation, using the
PartialModules system.
Additionally, this commit adds several unit and integration tests of various
flavors to test this change.
PR Close#22005
All of the providers in a module get compiled into a module definition in the
factory file. Some of these providers are for the actual module types, as those
are available for injection in Angular. For tree-shakeable tokens, the runtime

This change adds a NodeFlag which tags those module providers for later
identification.

For the initial rendering, where there is no transition from a previous
visual state to a new one, animations make little sense. The page should
load with as few reflows as possible.
Similarly, while we typically want to defer updating the SideNav state
(e.g. opened/closed) until the "leaving" document is animated out of the
page, on the initial rendering (where there is no "leaving" document)
this leads to the SideNav flashing (from closed to open).
These worked as expected before, but several parts (mostly related to
documents with a SideNav) have been accidentally broken in recent
commits (e.g. when upgraded to latest material, or enabled animations
for DocViewer transitions, etc.).

Previously, an interceptor attempting to inject HttpClient directly
would receive a circular dependency error, as HttpClient was

Users want to inject HttpClient into interceptors to make supporting

HttpClient at request time.
Either HttpClient or the user has to deal specially with the circular

itself. By utilizing a new class HttpInterceptingHandler which lazily

HttpClient directly into interceptors as construction of HttpClient no

The `<meta name="robots" content="noindex">` tag is used
to indicate to search engine crawlers that they should not index
the current page. This is set dynamically by the the document
viewer component to ensure that 404 and other erroring pages
are not added to the search index.
This relies upon the idea that the crawling bot will run the JS
and wait to see if this meta tag has been added or not.
Since we believe that the `googebot` will do this, we also
pre-emptively add a hard-coded noindex tag specifically for
this bot, so that if anything else fails in bootstrapping the app,
the failed page will not be added to the index.

PR Close#21350
When the SW fetches URLs listed in a manifest with hashes, it checks
the content hash against the manifest to make sure it has the correct
version of the URL. In the event of a mismatch, the SW is supposed to
consider the manifest invalid, and avoid using it. There are 3 cases
to consider by which this can happen.
Case 1: during the initial SW installation, a manifest is activated
without waiting for every URL to be fully loaded. In the background,
every prefetch URL listed by the manifest is requested and cached.
One such prefetch request could fail the hash test, and cause the
manifest to be treated as invalid. In such a case, the SW should
enter a state of EXISTING_CLIENTS_ONLY, as the latest manifest is
invalid.
This case works today.
Case 2: during the initial SW installation, as in Case 1, a manifest
is activated without waiting for each URL to fully load. However,
it's possible that the application could request a URL with a bad
hash before background initialization tries to load that URL. This
happens if, for example, the application has a broken index.html.
In this case, the SW should enter a state of EXISTING_CLIENTS_ONLY,
and serve the request from the network instead.
What happens today is that the internal error escapes the SW and
is returned as a rejected Promise to respondWith(), causing a
browser-level error that the site cannot be loaded, breaking the
site.
This change allows the SW to detect the error and enter the correct
state, falling back on the network if needed.
Case 3: during checkForUpdate(), the SW will try to fully cache the
new update before making it the latest version. Failure here is
complicated - if the page fails to load due to transient network
conditions (timeouts, 500s, etc), then it makes sense to continue
serving the existing cached version, and attempt to activate the
update on the next cycle.
If the page fails due to non-transient conditions though (400 error,
hash mismatch, etc), then the SW should consider the updated
manifest invalid, and enter a state of EXISTING_CLIENTS_ONLY.
Currently, all errors are treated as transient.
This change causes the SW to treat all errors during updates as
non-transient, which can cause the SW to unnecessarily enter a
safe mode. A future change can allow the SW to remain in normal mode
if the error is provably transient.

Currently the Service Worker checks for updates only on SW startup,
an event which happens frequently but also nondeterministically. This
makes it hard for developers to observe the update process or reason
about how updates will be delivered to users. This problem is
exacerbated by the DevTools behavior of keeping the SW alive
indefinitely while opened, effectively preventing the page from
updating at all.
This change causes the SW to additionally check for updates on
navigation requests (app page reloads). This creates deterministic
update behavior, and is much easier for developers to reason about.
It does leave the old update-on-SW-startup behavior in place, as
removing that would be a breaking change.

Structural directives can now specify a type guard that describes
what types can be inferred for an input expression inside the
directive's template.
NgIf was modified to declare an input guard on ngIf.
After this change, `fullTemplateTypeCheck` will infer that
usage of `ngIf` expression inside it's template is truthy.
For example, if a component has a property `person?: Person`
and a template of `<div *ngIf="person"> {{person.name}} </div>`
the compiler will no longer report that `person` might be null or
undefined.
The template compiler will generate code similar to,
```
if (NgIf.ngIfTypeGuard(instance.person)) {
instance.person.name
}
```
to validate the template's use of the interpolation expression.
Calling the type guard in this fashion allows TypeScript to infer
that `person` is non-null.

Not every application is served from the domain root. The Service
Worker made a bad assumption that it would be, and so requested
/ngsw.json from the domain root.
This change corrects this assumption, and requests ngsw.json without
the leading slash. This causes the request to be interpreted
relative to the SW origin, which will be the application root.
The Service Worker contains a mechanism by which it will postMessage
itself a signal to initialize its caches. Through this mechanism,
initialization happens asynchronously while keeping the SW process
alive.
Unfortunately in Firefox, the SW does not have the ability to
postMessage itself during the activation event. This prevents the
above mechanism from working, and the SW initializes on the next
fetch event, which is often too late.
Therefore, this change has the application wait for SW changes and
tells each new SW to initialize itself. This happens in addition to
the self-signal that the SW attempts to send (as self-signaling is
more reliable). That way even on browsers such as Firefox,
initialization happens eagerly.
Currently a bug exists where attempting to inject SwPush crashes the
application if Service Workers are unsupported. This happens because
SwPush doesn't properly detect that navigator.serviceWorker isn't
set.
This change ensures that all passive observation of SwPush and
SwUpdate doesn't cause crashes, and that calling methods to perform
actions on them results in rejected Promises. It's up to applications
to detect when those services are not available, and refrain from
attempting to use them.
To that end, this change also adds an `isSupported` getter to both
services, so users don't have to rely on feature detection directly
with browser APIs. Currently this simply detects whether the SW API
is present, but in the future it will be expanded to detect whether
a particular browser supports specific APIs (such as push
notifications, for example).
Currently, the way to not use the SW is to not install its module.
However, this means that you can't inject any of its services.
This change adds a ServiceWorkerModule.disabled() MWP, that still
registers all of the right providers but acts as if the browser does
not support Service Workers.

Closes#20184
This PR was merged without API docs and general rollout plan.
We can't release this as is in 5.1 without a plan for documentation, cli integration, etc.
It's illegal to coerce a Symbol to a string, and results in a TypeError:
TypeError: Cannot convert a Symbol value to a string
Previously, the custom jasmineToString() method monkey-patched onto Maps
in platform-browser/testing/src/matchers.ts would coerce keys and values
to strings. A change in a newer version of Jasmine calls this method more
often, resulting in calls against Maps which contain Symbols in some
applications, which causes crashes.
The fix is to explicitly convert keys and values to strings, which does
work on Symbols.
When this command is run on CI, `yarn build` has already been run, so
this was unnecessarily building angular.io again (adding ~4mins to the
`aio` job).
When this command is run locally, it is most often about testing a new
`lighthouse` version/config, so you don't need to build angular.io over
and over (and if necessary, one can always run `yarn build` manually).
Closes#19633
We use the globally installed yarn now. The local yarn was used in
`check-environment.js` only, which results in the `--integrity` check
always failing (if dependencies were installed with the global yarn).
Checks that cause the doc-gen to fail were already disabled in `docs-watch`
for the doc-gen that runs when a file is changed.
Now these checks are also disabled for the initial doc-gen run.
closes#20038
By setting `renderExamples.ignoreBrokenExamples = true` the doc-gen will
not fail if there is something wrong with an example. Instead it will
just log a warning.
Installing dependencies for the docs examples fails, because the
lockfile is out-of-sync with the corresponding `package.json`.
This commit brings the lockfile in sync with `package.json`.
(For reference, this was accidentally broken in #20039.)

Importing ServiceWorkerModule.register() will schedule registration of
the Service Worker inside an APP_INITIALIZER. Previously, the Promise
returned by navigator.serviceWorker.register() was returned from the
initializer function. This has the unwanted side effect of blocking
initialization until the SW is registered. Even worse, if the SW script
fails to load, this can cause the app initialization to fail.
The solution is to not return the registration promise from the
initializer function, essentially decoupling registration from the rest
of the initialization flow.

navigator.serviceWorker. A future integration test should cover this case
with better fidelity.

There is no difference in runtime (yet) between versioned and unversioned
files. Theoretically, the SW does not have to cache-bust versioned files,
but the SW doesn't cache bust files on the first request anyway, so in the
common case it doesn't matter. If the hash doesn't match, the SW will cache
bust the file to be sure, which is technically unnecessary, but since the
file itself is versioned, the likelihood of this happening is rare.
This fixes a critical bug where versioned files were erroneously not included
in the hashTable in the generated manifest. This could lead to applications
not updating if only versioned files changed in between versions.

The GaService and the E2E specs were unnecessarily complicated and had
arbitrary async timeouts to ensure that the interplay between the GA
library code and the rest of the app worked correctly. This resulted
in potential flaky tests if the timeouts were not adequate; this was
experienced when Travis upgraded to Chrome 62.
The new approach is to block loading of the Analytics library altogether
if there is a `__e2e__` flag set in the `SessionStorage` of the browser.
It doesn't appear to be enough just to set the flag directly on the
window. I think this is because the window gets cleaned when navigation
occurs (but I am not certain).
The downside of this is that we had to add a small piece of extra logic
to the GA snippet in index.html; and we also had to switch from using
`<script async ...>` to a programmatic approach to loading the GA library
which prevents the browser from eagerly fetching the library. This may
be mitigated by adding it to the HTTP/2 push configuration of the Firebase
hosting.

erroring in the same way that a real browser would. This bug is fixed by

The cause of this failure is a second bug in the data caching code, where
the Response is not cloned prior to being passed to Cache.put(). This is

This commit fixes several issues discovered through use in real apps.
* The sha1() function operated on text content, causing issues for binary-format files.
A sha1Binary() function which operates on unparsed data now avoids any encoding issues.
* The characters '?' and '+' were not escaped in Glob-to-regex conversion previously, but
are now.
* URLs from the browser contain the full origin, but were checked against the table of
hashes from the manifest which only has the path for URLs from the same origin. Now the
origin is checked and URLs are relativized to the domain root before comparison if
appropriate.
* ngsw: prefix was missing from data groups, is now added.
* Occasionally servers will return a redirected response for an asset, and caching it could
cause errors for navigation requests. The SW now handles this by detecting such responses
and following the redirect manually, to avoid caching a redirected response.
* The request for known assets is now created from scratch from the URL before fetching from
the network, in order to sanitize it and avoid carrying any special modes or headers that
might result in opaque responses.
* Debugging log for troubleshooting.
* Avoid creating errors by returning 504 responses on error.
* Fix bug where idle queue doesn't run in some circumstances.
* Add tests for the above.
This is important to not confuse users nor downstream tools that
consume our source maps. For generated content for which we don’t
have an original source file, we use the generated file now.

The current `flattenSummaries` function re-process the same NgModule
summary even if it has been processed before. Certain modules like
CommonModule are repeated multiple times in the module tree and it is
expanded out every time.
This was making unit tests using AOT summaries really slow. This will
also slow down JIT bootstrap applications that load AOT summaries for

The fix is to remember which summaries were seen before and not to
process them again.
Each node now has two index: nodeIndex and checkIndex.
nodeIndex is the index in both the view definition and the view data.
checkIndex is the index in in the update function (update directives and update
renderer).
While nodeIndex and checkIndex have the same value for now, having both of them
will allow changing the structure of view definition after compilation (ie for
runtime translations).

This service worker is a conceptual derivative of the existing @angular/service-worker maintained at github.com/angular/mobile-toolkit, but has been rewritten to support use across a much wider variety of applications.
Entrypoints include:
@angular/service-worker: a library for use within Angular client apps to communicate with the service worker.
@angular/service-worker/gen: a library for generating ngsw.json files from glob-based SW config files.
@angular/service-worker/ngsw-worker.js: the bundled service worker script itself.
@angular/service-worker/ngsw-cli.js: a CLI tool for generating ngsw.json files from glob-based SW config files.
Closure no longer needs to have the imports rewritten avoid rewriting
as this can cause issues when the source directory structure differs
from what is deployed.
Fixes: #19026
This is needed as:
- closure declares globals itself for minified names, which sometimes clobber our `ng` global
- we can't declare a closure extern as the namespace `ng` is already used within Google for typings for angularJS (via `goog.provide('ng....')`).
This is necessary to enable type-based optimizations with Closure.
Without explicity making these options the same named type, Closure
thinks they are different types and cannot disambiguate the `fromObject`
property.
Added the compiler options `strictInjectionParameters` that defaults
to `false`. If enabled the compiler will report errors for parameters
of an `@Injectable` that cannot be determined instead of generating a
warning.
This is planned to be switched to default to `true` for Angular 6.0.
Also adds auto upgrade from lower version based
on the .d.ts file (e.g. from version 3 to 4).
This is needed as we are now also capturing type aliases
in metadata files (and we rely on this),
see 6e3498ca8e.
`ng build ...` must be the last command on the corresponding yarn script,
because it needs to be passed extra arguments (such as the target environment)

This commit allows building angular.io against the locally built Angular
packages. It adds two new npm scripts:
- `setup-local`: Same as `setup`, but overwrites the Angular packages for both
angular.io and the examples boilerplate with the locally built ones.
- `build-local`: Same as `build`, but uses `setup-local` instead of `setup`
under the hood, thus overwriting installed Angular packages with locally built
ones.
Fixes#18611
The new expression lowering lowers everything after `useValue` / `useFactory`
into a separate exported variable. If the value was a `forwardRef`, this
was passed to the runtime and resulted in errors.
This change unwraps `forwardRef`s during runtime again.
Note: we can’t unwrap the `forwardRef` into an exported variable
during compile time, as this would defeat the purpose of the
`forwardRef` in referring to something that can’t be referred to
at this position.
introduce the option `allowEmptyCodegenFiles` to generate all generated files,

- previously every import in a stylesheet would generate a new

- now, we only generate 1 `.ngstyles.ts` file per entry in `@Component.styleUrls`.
This was required as we need to be able to determine the program files
without loading the resources (which can be async).

Uses Domino - https://github.com/fgnass/domino and removes dependency on
Parse5.
The DOCUMENT and nativeElement were never typed earlier and were
different on the browser(DOM nodes) and the server(Parse5 nodes). With
this change, platform-server also exposes a DOCUMENT and nativeElement
that is closer to the client. If you were relying on nativeElement on
the server, you would have to change your code to use the DOM API now
instead of Parse5 AST API.
Removes the need to add services for each and every Document
manipulation like Title/Meta etc.
This does *not* provide a global variable 'document' or 'window' on the
server. You still have to inject DOCUMENT to get the document backing
the current platform server instance.
Currently HttpClient sends requests for JSON data with the
XMLHttpRequest.responseType set to 'json'. With this flag, the browser
will attempt to parse the response as JSON, but will return 'null' on
any errors. If the JSON response contains an XSSI-prevention prefix,
this will cause the browser's parsing to fail, which is unrecoverable.
The only compelling reason to use the responseType 'json' is for
performance (especially if the browser offloads JSON parsing to a
separate thread). I'm not aware of any browser which does this currently,
nor of any plans to do so. JSON.parse and responseType 'json' both
end up using the same V8 code path in Chrome to implement the parse.
Thus, this change switches all JSON parsing in HttpClient to use
JSON.parse directly.

BREAKING CHANGE: Because of multiple bugs and browser inconsistencies, we have dropped the intl api in favor of data exported from the Unicode Common Locale Data Repository (CLDR).
Unfortunately we had to change the i18n pipes (date, number, currency, percent) and there are some breaking changes.
1. I18n pipes
* Breaking change:
- By default Angular now only contains locale data for the language `en-US`, if you set the value of `LOCALE_ID` to another locale, you will have to import new locale data for this language because we don't use the intl API anymore.
* Features:
- you don't need to use the intl polyfill for Angular anymore.
- all i18n pipes now have an additional last parameter `locale` which allows you to use a specific locale instead of the one defined in the token `LOCALE_ID` (whose value is `en-US` by default).
- the new locale data extracted from CLDR are now available to developers as well and can be used through an API (which should be especially useful for library authors).
- you can still use the old pipes for now, but their names have been changed and they are no longer included in the `CommonModule`. To use them, you will have to import the `DeprecatedI18NPipesModule` after the `CommonModule` (the order is important):
```ts
import { NgModule } from '@angular/core';
import { CommonModule, DeprecatedI18NPipesModule } from '@angular/common';
@NgModule({
imports: [
CommonModule,
// import deprecated module after
DeprecatedI18NPipesModule
]
})
export class AppModule { }
```
Dont forget that you will still need to import the intl API polyfill if you want to use those deprecated pipes.
2. Date pipe
* Breaking changes:
- the predefined formats (`short`, `shortTime`, `shortDate`, `medium`, ...) now use the patterns given by CLDR (like it was in AngularJS) instead of the ones from the intl API. You might notice some changes, e.g. `shortDate` will be `8/15/17` instead of `8/15/2017` for `en-US`.
- the narrow version of eras is now `GGGGG` instead of `G`, the format `G` is now similar to `GG` and `GGG`.
- the narrow version of months is now `MMMMM` instead of `L`, the format `L` is now the short standalone version of months.
- the narrow version of the week day is now `EEEEE` instead of `E`, the format `E` is now similar to `EE` and `EEE`.
- the timezone `z` will now fallback to `O` and output `GMT+1` instead of the complete zone name (e.g. `Pacific Standard Time`), this is because the quantity of data required to have all the zone names in all of the existing locales is too big.
- the timezone `Z` will now output the ISO8601 basic format, e.g. `+0100`, you should now use `ZZZZ` to get `GMT+01:00`.
| Field type | Format | Example value | v4 | v5 |
|------------|---------------|-----------------------|----|---------------|
| Eras | Narrow | A for AD | G | GGGGG |
| Months | Narrow | S for September | L | MMMMM |
| Week day | Narrow | M for Monday | E | EEEEE |
| Timezone | Long location | Pacific Standard Time | z | Not available |
| Timezone | Long GMT | GMT+01:00 | Z | ZZZZ |
* Features
- new predefined formats `long`, `full`, `longTime`, `fullTime`.
- the format `yyy` is now supported, e.g. the year `52` will be `052` and the year `2017` will be `2017`.
- standalone months are now supported with the formats `L` to `LLLLL`.
- week of the year is now supported with the formats `w` and `ww`, e.g. weeks `5` and `05`.
- week of the month is now supported with the format `W`, e.g. week `3`.
- fractional seconds are now supported with the format `S` to `SSS`.
- day periods for AM/PM now supports additional formats `aa`, `aaa`, `aaaa` and `aaaaa`. The formats `a` to `aaa` are similar, while `aaaa` is the wide version if available (e.g. `ante meridiem` for `am`), or equivalent to `a` otherwise, and `aaaaa` is the narrow version (e.g. `a` for `am`).
- extra day periods are now supported with the formats `b` to `bbbbb` (and `B` to `BBBBB` for the standalone equivalents), e.g. `morning`, `noon`, `afternoon`, ....
- the short non-localized timezones are now available with the format `O` to `OOOO`. The formats `O` to `OOO` will output `GMT+1` while the format `OOOO` will be `GMT+01:00`.
- the ISO8601 basic time zones are now available with the formats `Z` to `ZZZZZ`. The formats `Z` to `ZZZ` will output `+0100`, while the format `ZZZZ` will be `GMT+01:00` and `ZZZZZ` will be `+01:00`.
* Bug fixes
- the date pipe will now work exactly the same across all browsers, which will fix a lot of bugs for safari and IE.
- eras can now be used on their own without the date, e.g. the format `GG` will be `AD` instead of `8 15, 2017 AD`.
3. Currency pipe
* Breaking change:
- the default value for `symbolDisplay` is now `symbol` instead of `code`. This means that by default you will see `$4.99` for `en-US` instead of `USD4.99` previously.
* Deprecation:
- the second parameter of the currency pipe (`symbolDisplay`) is no longer a boolean, it now takes the values `code`, `symbol` or `symbol-narrow`. A boolean value is still valid for now, but it is deprecated and it will print a warning message in the console.
* Features:
- you can now choose between `code`, `symbol` or `symbol-narrow` which gives you access to more options for some currencies (e.g. the canadian dollar with the code `CAD` has the symbol `CA$` and the symbol-narrow `$`).
4. Percent pipe
* Breaking change
- if you don't specify the number of digits to round to, the local format will be used (and it usually rounds numbers to 0 digits, instead of not rounding previously), e.g. `{{ 3.141592 | percent }}` will output `314%` for the locale `en-US` instead of `314.1592%` previously.

This commit introduces a new Input property called
`ngFormOptions` to the `NgForm` directive. You can use it
to set default `updateOn` values for all the form's child
controls. This default will be used unless the child has

`ngModelOptions`.
Potential values: `change` | `blur` | `submit`
```html
<form [ngFormOptions]="{updateOn: blur}">
<input name="one" ngModel> <!-- will update on blur-->
</form>
```
For more context, see [#18577](https://github.com/angular/angular/pull/18577).

toString() from DefaultIterableDiffer is only used in tests and should not

This commit introduces a new option to template-driven forms that
improves performance by delaying form control updates until the
"blur" or "submit" event. To use it, set the `updateOn` property
in `ngModelOptions`.
```html
<input ngModel [ngModelOptions]="{updateOn: blur}">
```
Like in AngularJS, setting `updateOn` to `blur` or `submit` will
delay the update of the value as well as the validation status.
Updating value and validity together keeps the system easy to reason
about, as the two will always be in sync. It's also worth noting
that the value/validation pipeline does still run when the form is
initialized (in order to support initial values).
Upcoming PRs will address:
* Support for setting group-level `updateOn` in template-driven forms
* Option for skipping initial validation run or more global error
display configuration
* Better support of reactive validation strategies

BREAKING CHANGE
It is no longer possible to declare classes in this format.
```
Component({...}).
Class({
constructor: function() {...}
})
```
This format would only work with JIT and with ES5. This mode doesn’t
allow build tools like Webpack to process and optimize the code, which
results in prohibitively large bundles. We are removing this API
because we are trying to ensure that everyone is on the fast path by
default, and it is not possible to get on the fast path using the ES5
DSL. The replacement is to use TypeScript and `@Decorator` format.
```
@Component({...})
class {
constructor() {...}
}
```
The source map does not currently work with the transformer pipeline.
It will be re-enabled after TypeScript 2.4 is made the min version.
To revert to the former compiler, use the `disableTransformerPipeline` in
tsconfig.json:
```
{
"angularCompilerOptions": {
"disableTransformerPipeline": true
}
}
```
This commit adds support for setting default `updateOn` values
in `FormGroups` and `FormArrays`. If you set `updateOn` to
’blur’` at the group level, all child controls will default to `’blur’`,
unless the child has explicitly specified a different `updateOn` value.
```
const c = new FormGroup({
one: new FormControl()
}, {updateOn: blur});
```
It's worth noting that parent groups will always update their value and
validity immediately upon value/validity updates from children. In other
words, if a group is set to update on blur and its children are individually
set to update on change, the group will still update on change with its
children; its default value will simply not be used.
This commit also updates the version of `@angular/cli` used for docs examples.
The previous (transient) dependency `@ngtools/webpack` was not compatible with
`@angular/compiler-cli@>=5` and was breaking when running against the local
builds (currently at 5.0.0-beta.2). The version of `@ngtools/webpack` used by
the latest `@angular/cli` version is compatible with `@angular/compiler-cli@5`.
This change allows ReflectiveInjector to be tree shaken resulting
in not needed Reflect polyfil and smaller bundles.
Code savings for HelloWorld using Closure:
Reflective: bundle.js: 105,864(34,190 gzip)
Static: bundle.js: 154,889(33,555 gzip)
645( 2%)
BREAKING CHANGE:
`platformXXXX()` no longer accepts providers which depend on reflection.
Specifically the method signature when from `Provider[]` to
`StaticProvider[]`.
Example:
Before:
```
[
MyClass,
{provide: ClassA, useClass: SubClassA}
]
```
After:
```
[
{provide: MyClass, deps: [Dep1,...]},
{provide: ClassA, useClass: SubClassA, deps: [Dep1,...]}
]
```
NOTE: This only applies to platform creation and providers for the JIT
compiler. It does not apply to `@Compotent` or `@NgModule` provides
declarations.
Benchpress note: Previously Benchpress also supported reflective
provides, which now require static providers.
DEPRECATION:
- `ReflectiveInjector` is now deprecated as it will be remove. Use
`Injector.create` as a replacement.

Problem description: when using ngTemplateOutlet with context as
an object literal in a template and binding to the context's property
the embedded view would get re-created even if context object remains
essentially the same (the same shape, just update to one properties).
This happens since currently change detection will re-create object
references when an object literal is used and one of its properties
gets updated through a binding.
Solution: this commit changes ngTemplateOutlet logic so we take
context object shape into account before deciding if we should
re-create view or just update existing context.
Fixes#13407
There are now 3 modes for deployment: next, stable, archive.
We compute which mode (and other deployment properties)
from the `TRAVIS_BRANCH` and the `STABLE_BRANCH`.
If the TRAVIS_BRANCH is master we deploy as "next".
If the `TRAVIS_BRANCH` matches the `STABLE_BRANCH` we deploy as "stable".
Otherwise if the branch has a major version lower than the stable version
and its minor version is highest of similar branches we deploy as "archive".
For "archive" deployments we compute the firebase project and deployment
url based on the major version of the `TRAVIS_BRANCH`.
As well as choosing where to deploy the build, we also use this
to select the environment file for the AIO Angular app.
This will enable the app to change its rendering and behaviour
based on its mode.

By default, the value and validation status of a `FormControl` updates
whenever its value changes. If an application has heavy validation
requirements, updating on every text change can sometimes be too expensive.
This commit introduces a new option that improves performance by delaying
form control updates until the "blur" event. To use it, set the `updateOn`
option to `blur` when instantiating the `FormControl`.
```ts
// example without validators
const c = new FormControl(, { updateOn: blur });
// example with validators
const c= new FormControl(, {
validators: Validators.required,
updateOn: blur
});
```
Like in AngularJS, setting `updateOn` to `blur` will delay the update of
the value as well as the validation status. Updating value and validity
together keeps the system easy to reason about, as the two will always be
in sync. It's also worth noting that the value/validation pipeline does
still run when the form is initialized (in order to support initial values).
Closes#7113
This is possibly a temporary fix for the layout, until we decide whether we want

The Internationalisation documentation, "Translate text nodes" section, has an incomplete
markdown anchor, and leaks markdown into the page. Fix the anchor by adding the opening bracket.
The static reflectory check for macro function recursion was too
agressive and disallowed calling a function with argument that also
calls the same function. For example, it disallowed nested animation
groups.
Fixes: #17467
FormControls, FormGroups, and FormArrays now optionally accept an options
object as their second argument. Validators and async validators can be
passed in as part of this options object (though they can still be passed
in as the second and third arg as before).
```ts
const c = new FormControl(, {
validators: [Validators.required],
asyncValidators: [myAsyncValidator]
});
```
This commit also adds support for passing arrays of validators and async
validators to FormGroups and FormArrays, which formerly only accepted
individual functions.
```ts
const g = new FormGroup({
one: new FormControl()
}, [myPasswordValidator, myOtherValidator]);
```
This change paves the way for adding more options to AbstractControls,
such as more fine-grained control of validation timing.
The markdown processor expects an empty line between an opening tag and the
markdown content. (If there is no empty line, the content is interpreted as
plain HTML.)
Previously, the line between the opening `<td>` and the content contained
whitespace, which caused the content to be interpreted as HTML and not markdown.

Angular can make many assumptions about its event handlers. As a result
the bookkeeping for native addEventListener is significantly cheaper
than Zone's addEventLister which can't make such assumptions.
This change bypasses the Zone's addEventListener if present and always
uses the native addEventHandler. As a result registering event listeners
is about 3 times faster.

In Node.JS console.log/error/warn functions actually resuls in a socket
write which in turn is considered by Zone.js as an async task.
This means that if there is any exception during change detection in a platform-server
application the error handler will make the Angular Zone unstable which
in turn will cause change detection to run on next tick and cause an
infinite loop.
It is also better to run the error handler outside of the Angular Zone
in general on all platforms so that an error in the error handler itself doesn't cause an
infinite loop.

Note 4.3 only!
Prior to this fix when [@.disabled] was used in a component that
contained zero animation code it wouldn't register properly because the
renderer associated with that component was not an animation renderer.
This patch ensures that it gets registered even when there are no
animations set.
* Tell the app that this will have no Table of Contents, since we have no
h2 headings anyway.
* Remove all the `nbsp;` from the code since that doesn't help with layout
* Remove side padding from sidenav-content when screen is narrow
* Restyle the cheatsheet table when the screen is narrow

The API docs have changed. The line numbers are now found in
`startingLine` and `endingLine` properties rather than the `location`
property, which moved into the `fileInfo` property anyway.
In our attempt to remove the material ripple effect from tab labels, we were
killing all `transform`-based animations on other `md-tab-group` elements, such
as animating the content when entering/leaving. (This wasn't an issue on Chrome,
because it didn't respect our `!important` flag.)
This commit fixes it by properly hiding the ripple effect (using a feature
introduced in angular/material2@e4789c7b8) and allowing other animations to
execute normally.

Now that we have upgraded to the latest lunr search engine, the results
from the standard `search` method are more appropriate.
So we do not need to create our own special queries to get good results.
Since 808bd4af4, we are no longer pre-verifying PRs before uploading the build
artifacts to the preview server, thus we no longer need the
`travis-preverify-pr.sh` script or the `GITHUB_TEAM_MEMBERSHIP_CHECK_KEY`
variable.
This commit adds an API endpoint for notifying the preview server about PR
updates (`/pr-updated`). According to the update, the preview server can take
several actions. Currently, it will only check and (if necessary) update the
PR's preview visibility (but more actions could be supported in the future).
The API can be used with an automatic trigger (e.g. a GitHub webhook) to
instantly update a PR's preview visibility when it changes.
Fixes#16526
Previously, `BuildCreator#changePrVisibility()` would throw an error if the PR's
visibility was already up-to-date or if the PR directory did not exist (e.g. was
removed). This method was only used from inside `BuildCreator#create()`, which
had already checked for the existence of the directories.
This commit renames `changePrVisibility()` to `updatePrVisibility()` and makes
it more "forgiving" (i.e. it will only throw if both public and non-public
directories exist). This allows it to be used on events that may or may not have
caused the PR's visibility to change (e.g. a GitHub webhook triggered whenever a
PR's labels change).
Previously, there was a distinction between GET requests to invalid URLs and all
other requests. This was mainly because the upload-server only accepts GET
requests, but that is not a hard limitation and may change in the future.
Thus, it makes sense to return a 404 response for requests to invalid URLs
regardless of the method used.
HttpClient is an evolution of the existing Angular HTTP API, which exists
alongside of it in a separate package, @angular/common/http. This structure
ensures that existing codebases can slowly migrate to the new API.
The new API improves significantly on the ergonomics and features of the legacy
API. A partial list of new features includes:
* Typed, synchronous response body access, including support for JSON body types
* JSON is an assumed default and no longer needs to be explicitly parsed
* Interceptors allow middleware logic to be inserted into the pipeline
* Immutable request/response objects
* Progress events for both request upload and response download
* Post-request verification & flush based testing framework
Previouly, whenever a new ServiceWorker update was detected the user was
prompted to update (with a notification). This turned out to be more distracting
than helpful. Also, one would get notifications on all open browser tabs/windows
and had to manually reload each one in order for the whole content (including
the app) to be updated.
This commit changes the update strategy as follows:
- Whenever a new update is detected, it is immediately activated (and all
tabs/windows will be notified).
- Once an update is activated (regardless of whether the activation was
initiated by the current tab/window or not), a flag will be set to do a
"full page navigation" the next time the user navigates to a document.
Benefits:
- All tabs/windows are updated asap.
- The updates are applied authomatically, without the user's needing to do
anything.
- The updates are applied in a way that:
a. Ensures that the app and content versions are always compatible.
b. Does not distract the user from their usual workflow.
NOTE:
The "full page navigation" may cause a flash (while the page is loading from
scratch), but this is expected to be minimal, since at that point almost all
necessary resources are cached by and served from the ServiceWorker.

This commit changes the dynamic version of ngUpgrade to use `UpgradeHelper`,
thus bringing its behavior (wrt upgraded components) much closer to
`upgrade/static`. Fixes/features include:
- Fix template compilation: Now takes place in the correct DOM context, instead
of in a detached node (thus has access to required ancestors etc).
- Fix support for the `$onInit()` lifecycle hook.
- Fix single-slot transclusion (including optional transclusion and fallback
content).
- Add support for multi-slot transclusion (inclusing optional slots and fallback
content).
- Add support for binding required controllers to the directive's controller
(and make the `require` behavior more consistent with AngularJS).
- Add support for pre-/post-linking functions.
(This also ports the fixes from #16627 to the dynamic version.)
Fixes#11044
(#17971)
Although, pre- and post-linking functions are correctly called during directive
linking, directives with `link.post` would throw an error. Interestingly, having
`link.pre` only or defining `link: fn` (which is an alias for `link.post: fn`)
would not throw.
This commit removes this check and allows directives with pre- and/or
post-linking functions to work.
Previously, only simple, single-slot transclusion worked on upgraded components.
This commit fixes/adds support for the following:
- Multi-slot transclusion.
- Using fallback content when no transclusion content is provided.
- Destroy unused scope (when using fallback content).

Firebase does not allow `.` in the path, so when trying to upload payload size

Restores keyboard focus that was removed by commit b8b91d3.
Raises the right-TOC by 20px (96px->76px) because was too far down.
To prevent keyboard focus on hidden child nodes,
also collapses inner expanded nodes when parent node is collapsed.
The implicit parent node of top nodes is always expanded.
The window title is derived based on the current document's `<h1>` heading. Such
headings may contain hidden/non-visible content (e.g. textual name of font
ligatures: `<i class="material-icons">link</i>`) that should not be included in
the title.
This commit fixes this by using `innerText` (instead of `textContent`) to
extract the visible text from the `<h1>` heading. It will still fall back to
`textContent` on browsers that do not support `innerText` (e.g. Firefox 44).
Fixes#17732
Use the 7 first characters of the 40-chars long SHAs for shorter/cleaner URLs.
The collision probability is extremely low (since all SHAs are further
"namespaced" under the corresponding PR). In case of a collision, the second PR
will not be deployed, in order to avoid overwriting the original build.
(This is a design decision to keep the implementation simple. It can be changed
later if necessary.)
The previous clean-up code for PR directories on the preview server assumed that
all directories were named after the PR number. With the changes introduced
in #17640 it is possible to have PR directories that do not follow that naming
convention (e.g. "non-public" directories).
This PR ensures that both public and non-public directories are removed when
cleaning up.
When creating a new docker image for the preview server, the TypeScript source
code in `scripts-js/` is not copied over. Instead only the generated JavaScript
core in `scripts-js/dist/` are. Because of that, it is necessary to have run
`yarn build` before running `docker build`, so that the new docker image
contains the latest changes in `scripts-js/`.
This was previously part of the `create-image.sh` script, but was accidentally
removed in 21d213dfc.

This commit introduces the ability to show previews for PRs by any author. It works as follows:
- The build artifacts of all PRs are uploaded to the preview server.
- Automatically verified PRs (i.e. from trusted authors or having a specific label) are deployed and
publicly accessible as usual.
- PRs that could not be automatically verified are stored for later use (after re-verification).
- A PR can be marked as "trusted" and make its preview publicly accessible by adding the GitHub
label specified in the `AIO_TRUSTED_PR_LABEL` env var of the preview server.
At the moment, there is no automatic mechanism for notifying the preview server about changes to the
PR's verification status. The PR's "visibility" will be checked and updated every time a new build
is uploaded.
Before 4f37f8643, we were using `innerText` to retrieved the code content for
copying. This preserved the text layout (including newlines), but suffered from
other issues (browser support, performance). With 4f37f8643 we switched to
`textContent`, which works well except in the following case:
When `prettify` formats the code to have line numbers, it removes the newlines
and uses `<li>` elements instead. This affects `textContent`.
This commit fixes this by keeping a reference of the code as text and using that
for copying.
Fixes#17659

You can now specify what environment you are building

The API docs tests have very variable run times, depending
upon the build environment.
This change doubles their test timeout values to prevent
false-negative failures.
Previously, we always assumed that elements would be scrolled to the top of the
page, when calling `element.scrollIntoView()`. This is not true for elements
that cannot be scrolled to the top, e.g. when the viewport height is larger than
the height of the content after the element (common for small sections near the
end of the page).
In such cases, we would unnecessarily scroll up to account for the static
toolbar, which was unnecessary (since the element was not behind the toolbar
anyway) and caused ScrollSpy to fail to identify the scrolled-to section as
active.
This commit fixes it by ensuring that we do not scroll more than necessary in
order to align the top of the element with the bottom of the toolbar.

Chrome (v58+) often gets disconnected during unit tests (causing them to fail).
This has been happening locally (on Windows) and on Travis. The exact reasons
are not known, but it seems that some of the `AppComponent` tests are to blame.
Based on the discussion in https://github.com/jasmine/jasmine/issues/1327 (and
plenty of trial-and-error), using Jasmine's `done()` callback before each of
test (even calling it synchronously) fixes the issue.
Previously the RequestOptions/ResponseOptions classes had constructors
with a destructured argument hash (represented by the
{Request,Response}OptionsArgs type). This type consists entirely of
optional members.
This produces a .d.ts file which includes the constructor declaration:
constructor({param, otherParam}?: OptionsArgs);
However, this declaration doesn't type-check properly. TypeScript
determines the actual type of the hash parameter to be OptionsArgs | undefined,
which it then concludes does not have a `param` or `otherParam` member.
This is a bug in TypeScript ( https://github.com/microsoft/typescript/issues/10078 ).
As a workaround, destructuring is moved inside the method, where it does not produce
broken artifacts in the .d.ts.
Fixes#16663.

Closes#17245 and #17253
When the user selects a doc item in the side nav:
1) expand folder(s) leading to the selected doc item
2) on a wide display, keep other already expanded folders open
3) on narrow (mobile) display, collapse other expanded folders
Used to do (3) when wide. Issue #17245 asks for (2).
That logic was bypassed for selected node when we allowed headers to have content
because that unintentionally expanded the header’s folder when selected.
Because the selected node is no longer a header with content, removing this exclusion
also means that folders are expanded/collapsed with above logic even for API pages.
Rather than hard coding excludes into the dgeni config,
use the fact that we are already ignoring the boilerplate
and generated files via the .gitignore file.
Previously, the main content would always leave a 18% margin on the right to be
occupied by the ToC (even if there was no ToC).
This commit lets the main content expand to the right to occupy all the
available space when there is no ToC.
Fixes#17205Fixes#17270
Previously, when scrolling the ToC and reaching the top/bottom, further
mousewheel events would result in scrolling the window (and thus the main
content). This is standard browser behavior. In the case of the ToC though, the
`ScrollSpy` would detect scrolling in the main content and scroll the active ToC
to entry into view, thus resetting the scroll position of the ToC.
Reproduction:
1. Open `~/guide/template-syntax`.
2. Start scrolling through the long ToC.
3. Try to go to the bottom of the ToC.
4. Once you reach the bottom, the main content starts scrolling down.
5. The first section ("HTML in templates") becomes "active", so the ToC is
scrolled back up to make its corresponding entry visible.
6. Go back to step 2.
This commit improves the UX, by not allowing the main content to scroll when the
cursor is ovr the ToC and the user has scrolled all the way to the top/bottom of
it.
When navigating from a page with open SideNav to a page without closed SideNav,
the main content area animates from a non-zero left margin to zero left margin.
Additionally, the top-bar on the homepage is transparent, which allows the white
background behind the main content to be seen while the left margin is animated
to zero, making it appear as if something (e.g. the SideNav covers the top-bar).
This commit works around this issue, by not making the top-bar transparent
immediately when navigating to the homepage, but animating it from its blue
color to transparent with a delay.

Previously, the top-bar's height wasn't taken into account when scrolling an
element into view. As a result, the element would be hidden behind the top-bar.
Taking the top-bar height into account was not necessary before #17155, because
the top-bar was not fixed (i.e. it scrolled away).
This commit fixes the scrolling behavior by accounting for the top-bar's height
when scrolling an element into view.

nodes keyed off their view.

Previously, the `#top-of-page` element (used when scrolling to top) was placed
inside the content section (which at the time had zero top margin and padding).
Furthermore, there was a top offset applied when scrolling that took the static
top bar's height into account. Since now the top bar is not static any more and
the content section has a non-zero top padding, scrolling to top does not work
as expected.
This commit fixes this by:
- Moving the `#top-of-page` element to the top of the `aio-shell`.
- Stop accounting for the top bar's top.

Refactoring the compiler to use transformers moves the code generation
after type-checking which suppresses the errors TypeScript would
generate in the user code.
`TypeChecker` currently produces the same factory code that was
generated prior the switch to transfomers, getting back the same
diagnostics as before. The refactoring will allow the code to
diverge from the factory code and allow better diagnostic error
messages than was previously possible by type-checking the factories.

Lighthouse v1.6.5 treats localhost/1.2.7.0.0.1 as secure domains (i.e. as if they where HTTPS), so we need to stop handling the is-on-https audit specially.
In some cases (unclear when), traceviewer-js, used by Lighthouse under the hood,
assumes `atob`/`btoa` are defined in the global scope. This is true for browser
environments, but not on node.
As a result, some aggregations that required access to model-tracing failed to
produce results, dropping the overall PWA score.

Sidenav headers had been anchors w/o hrefs. These can’t take focus which makes you can’t navigate through them with keyboard. For a11y purposes, this PR turns them into buttons.
By reflex we began all component tests with an async `beforeEach` that called `compileComponents`.
In at least one case (`live-example.component.spec.ts`) that led to the `it` tests being async as well.
There is no need to call `.compileComponents` because CLI web pack + plugin inlines all templates and styles.
While `.compileComponents` was harmless, it added complexity and distraction which we should not inflict on future readers and testers.
Previously the logic for deciding when to display
the search result was spread between different
parts of the application and used non-intuitive logic
such as sending a blank results set to the searchResults.
This commit moves the management of displaying
the search results (and also setting focus of the
search input box) to the AppComponent. This makes
it easier to understand what happens and why; but
also allows the search UI components to be more
easily reused (such as embedding them in the 404
page).
(Coincidentally), this wasn't an issue before fdfeaaf1f, because
pre-verification was run after `test.sh`, during which `aio-builds-setup` was
built.
Now that `deploy-staging.sh` is being run before `test.sh`, we need to build
the `aio-builds-setup` scripts first.
Previously, `aio/aio-builds-setup/scripts/travis-preverify-pr.sh` was supposed
to exit with 1 if a PR did not meet the preconditions and 2 if an error occurred
during pre-verification.
It relied on the exit codes of the node script that did the actual work, but
didn't account for errors that would be thrown in the `sh` script itself (e.g.
if the node script was not available). This caused such errors to appear as
non-verified PRs, instead of real errors that should fail the build.
This commit swaps the exit codes, so that now a 2 means non-verified PR and 1
designates an error.
Hybrid apps (mix of Angular and AngularJS) might return AngularJS implementation
of Promises that do not play well with the change detection. Wrapping them in
native Promises fix this issue.
This could be the case when a Resolver returns a `$q` promise.

Closure compiler renames $inject.
Since abb36e3cb, we no longer rely on the cli to set up ServiceWorker, but do it
manually as part of `yarn build`. When using `ng serve`, registering the
ServiceWorker fails, because we haven't created `ngsw-manifest.json` nor copied
`worker-basic.min.js` into dist.
This commit works around this, by only registering the service worker in
production mode (which is what the cli does too).
Caveat:
It is not possible to enable ServiceWorker with `ng serve`/`yarn start` and
using the `--prod` flag will try to register it, but fail because the necessary
files (`ngsw-manifest.json` and `worker-basic.min.js`) will not be available.
(As a work-around, you can use `yarn build` and serve the files in `dist/` with
`yarn http-server -- dist -p 4200`.)
Previously, PR previews were deployed after successfully running all tests.
While this makes sense for staging/production deployments, previews should be

Previously, no previews would be deployed for PRs that didn't touch files inside
`aio/`. Now, previews will be deployed for PRs that touch non-spec files inside
either `aio/` or `packages/` (as long as other preconditions are met).

* fix(aio): allow code blocks to clear floated images
Previously the negative margin on the code headings were causing
floated images to overlay the start of a code block. Now all code block
successfully clear all floated elements.
* feat(aio): add a `.clear` class for clearing floating images
* fix(aio): tidy up image styles
The css rules for `img.right` and `img.left` allow authors easy
access to floating an image on the left or right, respectively.
The `.image-display` rule which was always found on a figure
has been simplified so that all figures have this styling. It is very
unlikely that a figure will be used outside the content area; and
at this time it seems like `figure` is as good an indicator that we
want this kind of styling as anything.
Now that images are all tagged with width and height values, we cannot
assume to modify these dimensions via CSS as it can cause the image to
lose its correct proportions. Until we find a better solition we must set
`height` to `auto` when the screen width is below 1300px to ensure that
these images maintain their proportions as they get shrunk to fit.
* docs(aio): general tidy up of image HTML in guides
Previously, the guides have a lot of inline image styling and unnecessary
use of the `image-display` css class.
Images over 700px are problematic for guide docs, so those have been given
specific widths and associated heights.
* docs(aio): use correct anchor for "back to the top" link
The `#toc` anchor does not work when the page is
wide enough that the TOC is floating to the side.
* build(aio): add `#top-of-page` to path variants for link checking
Since the `#top-of-page` is outside the rendered docs
the `checkAnchorLinks` processor doesn't find them
as valid targets for links.
Adding them as a `pathVariant` solves this problem
but will still catch links to docs that do not actually exist.
* fix(aio): ensure that headings clear floated images
* fix(aio): do not force live-example embedded image to 100% size
This made them look too big, generally. Leaving them with no size means
that they will look reasonable in large viewports and switch to 100% width
in narrow viewports.

Fixes#15521.
Currently, if a Response has an ArrayBuffer body and text() is called, Angular
attempts to convert the ArrayBuffer to a string. Doing this requires knowing
the encoding of the bytes in the buffer, which is context that we don't have.
Instead, we assume that the buffer is encoded in UTF-16, and attempt to process
it that way. Unfortunately the approach chosen (interpret buffer as Uint16Array and
create a Javascript string from each entry using String.fromCharCode) is incorrect
as it does not handle UTF-16 surrogate pairs. What Angular actually implements, then,
is UCS-2 decoding, which is equivalent to UTF-16 with characters restricted to the
base plane.
No standard way of decoding UTF-8 or UTF-16 exists in the browser today. APIs like
TextDecoder are only supported in a few browsers, and although hacks like using the
FileReader API with a Blob to force browsers to do content encoding detection and
decoding exist, they're slow and not compatible with the synchronous text() API.
Thus, this bug is fixed by introducing an encodingHint parameter to text(). The
default value of this parameter is 'legacy', indicating that the existing broken
behavior should be used - this prevents breaking existing apps. The only other
possible value of the hint is 'iso-8859' which interprets each byte of the buffer
with String.fromCharCode. UTF-8 and UTF-16 are not supported - it is up to the
consumer to get the ArrayBuffer and decode it themselves.
The parameter is a hint, as it's not always used (for example, if the conversion
to text doesn't involve an ArrayBuffer source). Additionally, this leaves the door
open for future implementations to perform more sophisticated encoding detection
and ignore the user-provided value if it can be proven to be incorrect.

Previously, non-bracketed inputs (e.g. `xyz="foo"`) on downgraded components
were initialized using `attrs.$observe()` (which uses `$evalAsync()` under the
hood), while bracketed inputs (e.g. `[xyz]="'foo'"`) were initialized using
`$watch()`. If the downgraded component was created during a `$digest` (e.g. by
an `ng-if` watcher), the non-bracketed inputs were not initialized in time for
the initial call to `ngOnChanges()` and `ngOnInit()`.
This commit fixes it by using `$watch()` to initialize all inputs. `$observe()`
is still used for subsequent updates on non-bracketed inputs, because it is more
performant.

The side nav and menu buttons need to appear early on in the loading of the page.
Currently we are using icon fonts with ligatures to get icons for these areas.
This can result in a flash of unstyled font.
By replacing these with SVG icons, we get a better user experience.
By overriding the `MdIconRegistry` we can inline the SVG source, which
means that there will never by a delay in rendering the icons.
The new `CustomMdIconRegistry` expects a multi-provider containing an array
of `SvgIconInfo` objects. These objects hold the name and SVG source of the
icon. When `MdIconComponent` requests an SVG icon we will get it from the
pre-loading cache, if available, before delegating back to the original
`MdIconRegistry`.
Note that SVG versions of `md-icon` do not apply the `material-icons` CSS
class to the element, so the styling for the icons that we are preloading
has been changed to use `.mat-icon` instead.

API search still updates query params as sending someone a pre-filtered API search link is handy.
While typing in the search box no longer updates the URL in the addr bar, you can still create a link like `~/?search=animations` and it will open the search dialog and profile the search box as it may be useful to email such a thing to someone.
Previously, the path returned by `LocationService.path()` preserved leading
slashes, which resulted in requests with consequtive slashes in the URL. Such
requests would fail (with a 404) on staging.
This commit fixes it, by removing leading slashes from the path. It also
refactors `LocationService` a bit, converting path to an observable,
`currentPath` (similar to `currentUrl`), and applies certain clean-ups (e.g.
stripping slashes, query, hash) in one place, which simplifies consumption.

Previously, the `AppComponent.pageId` was set via the current URL, rather than
the document being displayed. This is only really noticeable when the URL does not

which is returned from the `DocumentService.currentDocument` observable instead.
I found that VS Code was taking an age to bring up the intellisense
for TypeScript source files in the `aio/src` folder.
I believe that this is because it was trying to parse all the files in

web app development.
This change restricts the root `aio/tsconfig.json` to only the entry points
for the app, the unit tests and e2e tests.

This change adds that, if neither are provided, the first `<h1>` element
is removed from the `renderedContent` and used for the title.
If there is still no title then it is set to the empty string and a warning
is logged.

This only shows up in the language service. Calls to symbols

causing the language service to see exceptions when the null
was not expected such as in the animations array.
Fixes#15969
- always have a value for `angular`, even if no angular is on the page
- use `const` instead of `function` to allow to export a variable `module`
without breaking tsickle / closure.
Language service was treating some alias TypeScript symbols as if
they where the canonical symbol. If the symbol in scope is an alias
of another symbol the symbol should be converted to the canonical
symbol.
This task is suitable for day to day docs authoring.
This task cuts corners, which makes it much faster than a full `yarn docs`
run but it does not produce completely valid output.
In general this isgood enough for authors to see their changes as they make them.
The task is triggered by a call to
```
yarn docs-watch
```
This sets up watchers on the `aio/contents` and `packages` folders.
Any changes to files below these folders new doc generation run to start.
The input to the generation is confined to a collection of files related
to the changed file. For example:
* a change to a file in `aio/content/marketing` will generate all the
marketing files.
* a change to a file in `aio/content/tutorial` or `aio/examples/toh-*`
will generate all the tutorial files (and their embedded examples).
* a change to a file in `aio/guide` or `aio/examples` (but not a `toh-`
example) will generate the appropriate guide and its embedded examples
* a change to a file in `packages` or `packages/examples` will generate
the appropriate API doc and its embedded examples.
Be aware that the mapping between docs and its examples are based on doc file
and example folder structure being equivalent. Sometimes a doc will reference
an example in a different folder, in which case the generated doc will be
inaccurate. Mostly this is not a big problem.
When content pages were short, the footer would take up a large part

Previously, only a few characters of the SHA would appear on the preview link
comment posted on the PR. This was usually enough for GitHub to create a link to
the corresponding commit, but it was possible to have collisions with other
commits with the same first characters (which prevented GitHub from identifying
the correct commit and create a link.)
This commit fixes this issue by including the full SHA on the commentso GitHub
can identify the correct commit and create the link. GitHub will automatically
truncate the link text (by default to 7 chars unless more are necessary to
uniquely identify the commit).
Previously, when trying to upload the build artifacts for a PR/SHA that was
already successfully deployed (e.g. when re-running a Travis job), the preview
server would return a 403 and the build would fail.
Since we have other mechanisms to verify that the PR author is trusted and the
artifacts do indeed come from the specified PR and since the new artifacts
should be the same with the already deployed ones (same SHA), there is no reason
to fail the build. The preview server will reject the request with a special
HTTP status code (409 - Conflict), which the `deploy-preview` script will
recognize and exit with 0.
Don’t show the side nav in mobile (not side-by-side) view when arriving or navigating.

The implementation adds three plugins to the remark processor:
* remove support for code blocks triggered by indented
text - only gfm triple backticks are supported; and also adds support for
dgeni inline tags.
* ignore content within `code-example` and `code-tabs` elements. This prevents
the content being accidentally treated as markdown
* ignore dgeni inline tags, e.g. `{@link ... }` to prevent the content of
the links from being accidentally treated as markdown
* Fixes that `tsc-wrapped` stores invalid path separators in the bundled metadata files. Previous errors could have been: `Cannot find module '.corecoordinationnique-selection-dispatcher'.` (See https://github.com/angular/material2/issues/3834)
* Fixes failing tests on Windows. Now all tooling tests are green on Windows.

Sometimes, depending on the length of lines, anchor elements would be formatted
incorrectly by `html.prettyPrint` and the space right after the element was
removed.
This was apparently caused by a bug in `html.prettyPrint` in combination with
its default behavior of wrapping lines at a specific limit (70 chars). Since the
output is only meant to be used as JSON string data, wrapping the lines makes it
less readable by adding unnecessary `\n`.
This commit disables the line wrapping, which effectively avoids the bug that
was responsible for incorrectly formatting anchor elements and surrounding
space.
Related to #15681.
This version changes the expected syntax for emphasis.
The original Rho renderer uses `*` for strong an `_` for em.
But it is more standard in markdown to use `**` or `__` for bold
and `*` or `_` for em.

in another compilation unit.

Closes#15494
The markdown renderer passes its output through an HTML pretty printer.
While this is good in most cases, it makes a mess of elements that expect
their content to be left untouched.
The pretty printer already ignores `pre` tags (and other built-ins) by
default. This fix allows us to specify other tags that should be left
alone.
Further it actually specifies this option for `code-example` and `code-pane`
tags, which expect to contain preformatted content.
Fixes#15528
What is the current behavior?
The language service access TypeScript's Symbol.members without checking for null or undefined.
What is the new behavior?
The access is guarded.
This processor will eventually replace the `{@example}` inline tags
because it provides a cleaner approach that also supports tabbed examples
straight out of the box.
The idea is that authors will simply add a `path` and (optionally) a `region`
attribute to `<code-example>` or `<code-pane>` elements in their docs.
This indicates to dgeni that the relevant example needs to be injected
into the content of this element.
For example, assume that there is an example file `toh-pt1/index.hml` with
a region called `title`, which looks like:
```
<h1>Tour of Heroes</h1>
```
Then the document author could get this to appear in the docs as a
standalone example:
```
<code-example path="toh-pt1" region="title"></code-example>
```
Or as part of a tabbed group:
```
<code-tabs>
<code-pane path="toh-pt1" region="title"></code-pane>
</code-tabs>
```
If no `path` attribute is provided then the element is ignored, which
enables authors to provide inline code instead:
```
<code-example>
Some <html> escaped code
</code-example>
```
Also all attributes other than `path` and `region` are ignored and passed
through to the final rendered output allowing the author to provide
styling hints:
```
<code-example path="toh-pt1" region="title" linenums"15" class="important">
</code-example>
```
Fixes#14417
Updated example to illustrate @ContentChildren default behavior (only query direct children), and how to query for nested elements/all descendants.
This has the side effect of allowing `@Input` and `@ContentChild`

Fixes#15417
Previously, all URLs were rewritten to `index.html` in order to support
deep-linking. This works when navigating to URLs that correspond to existing
resources. E.g. navigating to `/tutorial` returns `index.html` and then the
`DocViewer` takes over and requests `tutorial.json`.
Navigating to a non-existent URL (e.g. `/foo`), will return `index.html`, which
in turn requests (the non-existent) `foo.json` and throws an error when trying
to parse the returned `index.html` as JSON.
This commit fixes it by only rewriting URLs that do not request a file (i.e. do
not include a `.` in the last path segment).

Added an "origins" section to the flat module `.metadata.json` files

This commit fixes a regression where `ngModel` no longer syncs
letter by letter on Android devices, and instead syncs at the
end of every word. This broke when we introduced buffering of
IME events so IMEs like Pinyin keyboards or Katakana keyboards
wouldn't display composition strings. Unfortunately, iOS devices
and Android devices have opposite event behavior. Whereas iOS
devices fire composition events for IME keyboards only, Android
fires composition events for Latin-language keyboards. For
this reason, languages like English don't work as expected on
Android if we always buffer. So to support both platforms,
composition string buffering will only be turned on by default
for non-Android devices.
However, we have also added a `COMPOSITION_BUFFER_MODE` token
to make this configurable by the application. In some cases, apps
might might still want to receive intermediate values. For example,
some inputs begin searching based on Latin letters before a
character selection is made.
As a provider, this is fairly flexible. If you want to turn
composition buffering off, simply provide the token at the top
level:
```ts
providers: [
{provide: COMPOSITION_BUFFER_MODE, useValue: false}
]
```
Or, if you want to change the mode based on locale or platform,
you can use a factory:
```ts
import {shouldUseBuffering} from 'my/lib';
....
providers: [
{provide: COMPOSITION_BUFFER_MODE, useFactory: shouldUseBuffering}
]
```

This shouldn't change anything. But it's interesting that we used to have this import
that seemed bogus, but there were no compilation or rutime errors.
Content pages like `tutorial/index.md` were being mapped to `tutorial.index.json`,
which meant that they could only be rendered if you browsed to `/tutorial/index`.
This didn't sit well so now these pages are mapped to `tutorial.json`, which
means that you browser to them via `/tutorial/` or just `/tutorial`.

The original Rho is too strict when it comes to markdown headings.
It requires that there be a blank line separating the heading and the
next paragraph. The forked version here fixes that; but the Rho project
will not merge it as it goes against there basic rules.
Unlike in the browser, on the server there is no concept of a document origin.
Thus, it is illegal to make requests for relative URLs against Http on platform-server.
Currently this fails with a vague error:
Error: Uncaught (in promise): Error at resolvePromise
This change adds explicit validation and a friendlier error message:
Error: URLs requested via Http on the server must be absolute. URL: /testing
Another option considered was to track the concept of an origin for the platform
and automatically prepend it to relative URLs. This would cause automatic "local
RPCs" to be made, though, which would be an unexpected and undesirable default
behavior.

Closes#15183
PR Close#15319
The Router use the type `Params` for all of:
- position parameters,
- matrix parameters,
- query parameters.
`Params` is defined as follow `type Params = {[key: string]: any}`
Because parameters can either have single or multiple values, the type should
actually be `type Params = {[key: string]: string | string[]}`.
The client code often assumes that parameters have single values, as in the
following exemple:
```
class MyComponent {
sessionId: Observable<string>;
constructor(private route: ActivatedRoute) {}
ngOnInit() {
this.sessionId = this.route
.queryParams
.map(params => params['session_id'] || 'None');
}
}
```
The problem here is that `params['session_id']` could be `string` or `string[]`
but the error is not caught at build time because of the `any` type.
Fixing the type as describe above would break the build because `sessionId`
would becomes an `Observable<string | string[]>`.
However the client code knows if it expects a single or multiple values. By
using the new `ParamMap` interface the user code can decide when it needs a
single value (calling `ParamMap.get(): string`) or multiple values (calling
`ParamMap.getAll(): string[]`).
The above exemple should be rewritten as:
```
class MyComponent {
sessionId: Observable<string>;
constructor(private route: ActivatedRoute) {}
ngOnInit() {
this.sessionId = this.route
.queryParamMap
.map(paramMap => paramMap.get('session_id') || 'None');
}
}
```
Added APIs:
- `interface ParamMap`,
- `ActivatedRoute.paramMap: ParamMap`,
- `ActivatedRoute.queryParamMap: ParamMap`,
- `ActivatedRouteSnapshot.paramMap: ParamMap`,
- `ActivatedRouteSnapshot.queryParamMap: ParamMap`,
- `UrlSegment.parameterMap: ParamMap`
Previously, a pipe that returned a `WrappedValue` would force the change

ErrorHandler can not throw errors because it will unsubscribe itself from
the error stream.
Zones captures errors and feed it into NgZone, which than has a Rx Observable
to feed it into ErrorHandler. If the ErroHandler throws, then Rx will teardown
the observable which in essence causes the ErrorHandler to be removed from the
error handling. This implies that the ErrorHandler can never throw errors.

Observable subscriptions from previous validation runs should be canceled
before a new subscription is created for the next validation run.
Currently the subscription that sets the errors is canceled properly,
but the source observable created by the validator is not. While this
does not affect validation status or error setting, the source
observables will incorrectly continue through the pipeline until they
complete. This change ensures that the whole stream is canceled.
AsyncValidatorFn previously had an "any" return type, but now it more
explicitly requires a Promise or Observable return type. We don't
anticipate this causing problems given that any other return type
would have caused a runtime error already.
Previously, style values were parsed with a regex that split on /:+/.
This causes errors for CSS such as
div {
background-url: url(http://server.com/img.png);
}
since the regex would split the background-url line into 3 values instead of 2.
Now, the : character is detected with indexOf, avoiding this error.
A test was added to verify the behavior is correct.
Implemented style guide elements to top header bar, side hamburger nav menu, content and search. Consolidated SCSS files to styles folder. Fixed PWA test.
The input may still have focus when the user hits ESC,
causing the search to be hidden.

BREAKING CHANGE:
Perviously, any provider that had an ngOnDestroy lifecycle hook would be created eagerly.
Now, only classes that are annotated with @Component, @Directive, @Pipe, @NgModule are eager. Providers only become eager if they are either directly or transitively injected into one of the above.
This also makes all `useValue` providers eager, which
should have no observable impact other than code size.
EXPECTED IMPACT:
Making providers eager was an incorrect behavior and never documented.
Also, providers that are used by a directive / pipe / ngModule stay eager.
So the impact should be rather small.

* Ensure that all indexed documents are displayed in the search results.
(Previously the guide documents were not appearing because we only showed

* Hide the results when the user hits the ESC key.
* Hide the results when the user clicks on a search result
Closes#14852
Adds tests and fixes corners cases for both `search()` and `setSearc()`
for things like empty queries and param keys that need encoding.
This commit refactors the `LocationService` to rely upon the `PlatformLocation`
rather than using `window.history` directly. This makes testing easier but also
makes the code simpler since `PlatformLocation` deals with platforms that
do not support history for us.
This can be used to e.g. add the NoopAnimationsModule by default:
```
TestBed.initTestEnvironment([
BrowserDynamicTestingModule,
NoopAnimationsModule
], platformBrowserDynamicTesting());
```

DEPRECATION:
Use `RouterModule.forRoot(routes, {initialNavigation: 'enabled'})` instead of
`RouterModule.forRoot(routes, {initialNavigtaion: true})`.
Before doing this, move the initialization logic affecting the router
from the bootstrapped component to the boostrapped module.
Similarly, use `RouterModule.forRoot(routes, {initialNavigation: 'disabled'})`
instead of `RouterModule.forRoot(routes, {initialNavigation: false})`.
Deprecated options: 'legacy_enabled', `true` (same as 'legacy_enabled'),
'legacy_disabled', `false` (same as 'legacy_disabled').

Previously, the relative order of the AngularJS compiling/linking operations was
not similar to AngularJS's, resulting in inconsistent behavior for upgraded
components (which made upgrading to Angular less straight forward).
This commit fixes it, by following the compiling/linking process of AngularJS
more closely.
Main differences:
- The components view is already populated when the controller is instantiated
(and subsequent hooks are called).
- The correct DOM content is available when running the `$onChanges`, `$onInit`,
`$doCheck` hooks. Previously, the "content children" were still present, not
the "view children".
- The same for pre-linking.
- The template is compiled in the correct DOM context (e.g. has access to
ancestors). Previously, it was compiled in isolation, inside a dummy element.
For reference, here is the order of operations:
**Before**
1. Compile template
2. Instantiate controller
3. Hook: $onChanges
4. Hook: $onInit
5. Hook: $doCheck
6. Pre-linking
7. Collect content children
8. Insert compiled template
9. Linking
10. Post-linking
11. Hook: $postLink
**After**
1. Collect content children
2. Insert template
3. Compile template
4. Instantiate controller
5. Hook: $onChanges
6. Hook: $onInit
7. Hook: $doCheck
8. Pre-linking
9. Linking
10. Post-linking

Fixes#13912
For some reason the tree-shaker is not picking up these interfaces
(perhaps TS is not passing it through) when they are in the same file
as their related services. This results in a distracting warning message.
There is a weirdness in the Angular Location service.
If the `baseHref` is only a single slash (`'/'`) then it
changes it to be an empty string (`''`). The effect of this
is that `Location.normaliseUrl(url)` does not strip off the
leading slash from url paths.
The problem is that the leading slash only appears on the
initial Location path, and not on urls that arrive from subscribing
to the Location service.
This commit is a workaround this problem.
Generate the docs with `yarn docs`.
Test the doc generation code with `yarn docs-test`
The docs are automatically built as part of the `yarn build` task,
so there is no need to rebuild them in the test_aio.sh file
Secondary entry points (testing, static, etc) are rolled up into a
single ESM/ES2015 file, then downleveled to ESM/ES2015. This downleveling
was not working and was producing ESM/ES2015. Also, the @angular/core
package's .babelrc file was missing reference to Rx Observable which
broke the UMD bundle.
Fixes#14730
After the introduction of the view engine, we can drop a lot of code that is not used any more.
This should reduce the size of the app bundles because a lot of this code was not being properly tree-shaken by today's tools even though it was dead code.
E.g. for no view encapsulation, the delegate will always be the same.
Nevertheless, we still need to create a new `AnimationRenderer` per
component.
Attention: This change will conflict with a local mod in G3.
- Don’t use the animation renderer if a component
used style encapsulation but no animations.
- The `AnimationRenderer` should be cached in the same
lifecycle as its delegate.
- Trigger names need to be namespaced per component type.
This change allows the example writer to add doc-region annotations to
files that do not allow comments. This is done by creating a clone of the
file and adding `.annotated` to the file name. This new file can contain
inline `// ...` comments that can be used to annotate the doc regions.
Example:
**package.json**
```
{
"name": "angular.io",
"version": "0.0.0",
"main": "index.js",
"repository": "git@github.com:angular/angular.git",
"author": "Angular",
"license": "MIT",
"private": true,
}
````
**package.json.annotated**
```
{
"name": "angular.io",
// #docregion version
"version": "0.0.0",
// #enddocregion
"main": "index.js",
"repository": "git@github.com:angular/angular.git",
"author": "Angular",
"license": "MIT",
"private": true,
}
````
This region can then be referenced in examples just like any other doc region:
```
{@example 'package.json' region="version"}
```
When the `enableLegacyTemplate` is set to `false`, `<template>` tags and the
`template` attribute are no more used to define angular templates but are
treated as regular tag and attribute.
The default value is `true`.
In order to define a template, you have to use the `<ng-template>` tag.
This option applies to your application and all the libraries it uses. That is
you should make sure none of them rely on the legacy way to defined templates
when this option is turned off (`false`).
The rationale of this change is to improve the inter-operability with web
components that might make use of the `<template>` tag.
DEPRECATION
The template tags and template attribute are deprecated:
<template ngFor [ngFor]=items let-item><li>...</li></template>
<li template="ngFor: let item of items">...</li>
should be rewritten as:
<ng-template ngFor [ngFor]=items let-item><li>...</li></ng-template>
Note that they still be supported in 4.x with a deprecartion warning in
development mode.
MIGRATION
- `template` tags (or elements with a `template` attribute) should be rewritten
as a `ng-template` tag,
- `ng-content` selectors should be updated to referto a `ng-template` where they
use to refer to a template: `<ng-content selector="template[attr]">` should be
rewritten as `<ng-content selector="ng-template[attr]">`
- if you consume a component relying on your templates being actual `template`
elements (that is they include a `<ng-content selector="template[attr]">`). You
should still migrate to `ng-template` and make use of `ngProjectAs` to override
the way `ng-content` sees the template:
`<ng-template projectAs="template[attr]">`
- while `template` elements are deprecated in 4.x they continue to work.
BREAKING CHANGE: Because all lifecycle hooks are now interfaces
the code that uses 'extends' keyword will no longer compile.
To migrate the code follow the example below:
Before:
```
@Component()
class SomeComponent extends OnInit {}
```
After:
```
@Component()
class SomeComponent implements OnInit {}
```
we don't expect anyone to be affected by this change.

Use `RendererV2` instead of `Renderer` now. `Renderer` can still be injected
and delegates to `RendererV2`.
Use `RendererFactoryV2` instead of `RootRenderer`. `RootRenderer` cannot be used

Note: `Renderer` can still be injected/used, but is deprecated.
Change required in previous commit ab96257bc that upgrades the CLI version.
env.sh: protractor v.5 requires a later version of chromium. Upping to 433059/Chrome 56.
Currently styles are rendered to the root component element, which ensures they're cleaned up automatically
when the client application is bootstrapped. This is less than ideal as progressive rendering can cause HTML
to be rendered before the CSS is loaded, causing flicker.
This change returns to rendering <style> elements in the <head>, and introduces a mechanism for removing
them on client bootstrap. This relies on associating the server and client bootstrap. Another way to think
of this is that the client, when bootstrapping an app, needs to know whether to expect a server rendered
application exists on the page, and to identify the <style> elements that are part of that app in order
to remove them.
This is accomplished by providing a string TRANSITION_ID on both server and client. For most applications,
this will be achieved by writing a client app module that imports BrowserModule.withServerTransition({appId: <id>}).
The server app module will import this client app module and therefore inherit the provider for
TRANSITION_ID. renderModule[Factory] on the server will validate that a TRANSITION_ID has been provided.
TypeScript compiler will now build to ES2015 code and modules. Babili is used to minify ES2015
code, providing an initial optimization that we couldn't previously get just from Uglify. Uses
Babel to convert ES2015 to UMD/ES5 code, and Uglify to minimize the output.
Some versions of TypeScript are super slow to compile functions that
contain a lot of `if` conditions in them. Splitting the handle event
expressions per element is similar to what we did in the old codegen.
Allow to style components that don’t use shadow dom inside of components that do.
This reverts 53cf2ec573
and adds a test for this case.

Note that this does not yet include enabling the view engine
by default.
Included refactoring:
- view engine: split namespace of elements / attributes already
when creating the `NodeDef`
- view engine: when injecting the old `Renderer`, use an implementation
that is based on `RendererV2`
- view engine: store view queries in the component view, not
on the host element
Included refactoring:
- splits the `RendererV2` into a `RendererFactoryV2` and a `RendererV2`
- makes the `DebugRendererV2` a private class in `@angular/core`
- remove `setBindingDebugInfo` from `RendererV2`, but rename `RendererV2.setText` to
`RendererV2.setValue` and allow it on comments and text nodes.
Part of #14013
This change installs HttpModule with ServerModule, and overrides bindings to
service Http requests made from the server with the 'xhr2' NPM package.
Outgoing requests are wrapped in a Zone macro-task, so they will be tracked
within the Angular zone and cause the isStable API to show 'false' until they
return. This is essential for Universal support of server-side HTTP.
This ensures when the tree is serialized to the client and the app is later bootstrapped,
the <style> tags created during server-side rendering are destroyed.
Aspects: di, query, content projection
Included refactoring:
- use a number as query id
- use a bloom filter for aggregating matched queries of nested elements
- separate static vs dynamic queries

This commit updates the doc-gen to account
for the changes to the codebase for decorators.
There are actually three kinds of calls that create decorators:
* makeDecorator
* makePropDecorator
* makeParamDecorator
Also, the actual documentation for each
decorator is split between two exported symbols:
* `interface [DecoratorName]` contains the metadata fields
* interface [DecoratorName]Decorator` contains a
"call member" which holds the general description of the decorator.
This processor now identifies all three decorator types, and pulls the
description of the callMember onto the main decorator doc description.
(There are some outstanding interfaces in the angular/angular project that
need to be re-exported from `/angular/modules/@angular/core/src/metadata.ts`
to ensure that the doc-gen is able to access them.)

1. Use `jasmine` as framework instead of `jasmine2`.

2. Simplify the `chromeOptions` config by always setting.
(If `process.env.CHROME_BIN` is not defined, `binary` will be ignored.)
Much of the formatting was hardcoded and copied from the old anguar.io
jade files. This gives us a clean start.
Also, more use has been made of include files to make the templates
easier to understand and manage.
Note, this affects the underlying class and should not affect usage.
DEPRECATION:
- the `NgFor` class is now deprecated. Use `NgForOf<T>` instead.
IMPORTANT: Only the `NgFor` class is deprecated, not the `ngFor`
directive. The `*ngFor` and related directives are unaffected by
this change as references to the `NgFor` class generated from
templates will be automatically converted to references to
`NgForOf<T>` without requiring any template modifications.
- `TrackByFn` is now deprecated. Use `TrackByFunction<T>` instead.
Migration:
- Replace direct references to the `NgFor` class to `NgForOf<any>`.
- Replace references to `TrackByFn` to `TrackByFunction<any>`.
BREAKING CHANGE:
A definition of `Iterable<T>` is now required to correctly compile
Angular applications. Support for `Iterable<T>` is not required at
runtime but a type definition `Iterable<T>` must be available.
`NgFor`, and now `NgForOf<T>`, already supports `Iterable<T>` at
runtime. With this change the type definition is updated to reflect
this support.

Correctly wire up hierarchical injectors for downgraded components in
`upgrade/static`: Downgraded components inherit the injector of the first
downgraded component up the DOM tree.
This is similar to (part of) d91a86a, but for `upgrade/static`.
POSSIBLE BREAKING CHANGE:
In order to enable more control over the wiring of downgraded components and
their content (which eventually allows better control over features like
injector setup and content projection), it was necessary to change the
implementation of the directives generated for downgraed components.
The directives are now terminal and manually take care of projecting and
compiling their contents in the post-linking function. This is similar to how
the dynamic version of `upgrade` does it.
This is not expected to affect apps, since the relative order of individual
operations is preserved. Still, it is difficult to predict how every possible
usecase may be affected.
This affects the dynamic version of `upgrade` and makes it more consistent with
the static version, while removing an artificial limitation.
This commit also refactors the file layout and code, in order to share code wrt
to dowgrading components between the dynamic and static versions.
This makes it more consistent with the dynamic version of `upgrade` and makes it
possible to share code between the dynamic and static versions.
This commit also refactors the file layout, moving common and dynamic-specific
files to `common/` and `dynamic/` directories respectively and renaming `aot/`
to `static/`.
Some private keys, used as AngularJS DI tokens, have also been renamed, but this
should not affect apps, since these keys are undocumented and not supposed to
be used externally.
BREAKING CHANGE:
Previously, `upgrade/static/downgradeInjectable` returned an array of the form:
```js
['dep1', 'dep2', ..., function factory(dep1, dep2, ...) { ... }]
```
Now it returns a function with an `$inject` property:
```js
factory.$inject = ['dep1', 'dep2', ...];
function factory(dep1, dep2, ...) { ... }
```
It shouldn't affect the behavior of apps, since both forms are equally suitable
to be used for registering AngularJS injectable services, but it is possible
that type-checking might fail or that current code breaks if it relies on the
returned value being an array.

This commit effectively reverts 7e0f02f but for `upgrade/static`
as it was an invalid fix for #6385, that created a more significant
bug, which was that changes were not always being detected.
Angular 1 digests should be run inside the ngZone to ensure
that async changes are detected.
We don't know how to fix#6385 without breaking change detection
at this stage. That issue is triggered by async operations, such as
`setTimeout`, being triggered inside scope watcher functions.
One could argue that watcher functions should be pure and not do
work such as triggering async operations. It is possible that the
original use case could be supported by moving the debounce
logic into the watch listener function, which is only called if the
watched value actually changes.

There are restrictions on the character set that can be used for xmb and xtb
placeholder names.
However because changing the placeholder names would change the message IDs it
is not possible to add those restrictions to the names used internally. Then we
have to map internal name to public names when generating an xmb file and back
when translating using an xtb file.
Note for implementors of `Serializer`:
- When writing a file, the implementor should take care of converting the
internal names to public names while visiting the message nodes - this is
required because the original nodes are needed to compute the message ID.
- When reading a file, the implementor does not need to take care of the mapping
back to internal names as this is handled in the `I18nToHtmlVisitor` used by the
`TranslationBundle`.

- Introduce `InjectionToken<T>` which is a parameterized and type-safe
version of `OpaqueToken`.
DEPRECATION:
- `OpaqueToken` is now deprecated, use `InjectionToken<T>` instead.
- `Injector.get(token: any, notFoundValue?: any): any` is now deprecated
use the same method which is now overloaded as
`Injector.get<T>(token: Type<T>|InjectionToken<T>, notFoundValue?: T): T;`.
Migration
- Replace `OpaqueToken` with `InjectionToken<?>` and parameterize it.
- Migrate your code to only use `Type<?>` or `InjectionToken<?>` as
injection tokens. Using other tokens will not be supported in the

BREAKING CHANGE:
- Because `injector.get()` is now parameterize it is possible that code
which used to work no longer type checks. Example would be if one
injects `Foo` but configures it as `{provide: Foo, useClass: MockFoo}`.
The injection instance will be that of `MockFoo` but the type will be
`Foo` instead of `any` as in the past. This means that it was possible
to call a method on `MockFoo` in the past which now will fail type
check. See this example:
```
class Foo {}
class MockFoo extends Foo {
setupMock();
}
var PROVIDERS = [
{provide: Foo, useClass: MockFoo}
];
...
function myTest(injector: Injector) {
var foo = injector.get(Foo);
// This line used to work since `foo` used to be `any` before this
// change, it will now be `Foo`, and `Foo` does not have `setUpMock()`.
// The fix is to downcast: `injector.get(Foo) as MockFoo`.

This commit effectively reverts 7e0f02f96e
as it was an invalid fix for #6385, that created a more significant
bug, which was that changes were not always being detected.
Angular 1 digests should be run inside the ngZone to ensure
that async changes are detected.
We don't know how to fix#6385 without breaking change detection
at this stage. That issue is triggered by async operations, such as
`setTimeout`, being triggered inside scope watcher functions.
One could argue that watcher functions should be pure and not do
work such as triggering async operations. It is possible that the
original use case could be supported by moving the debounce
logic into the watch listener function, which is only called if the
watched value actually changes.

While authoring this document we agreed to pushing off the 4.0.0 release by one week by adding one more RC week (compared to the original plan).
We announced that RC would take 1 month, but then I did the calendar math incorrectly.
This schedule change will give community more time to test the release before we call it done and report any potential regression or unforeseen issues.
The change avoids the compiler CLI internal API from mismatching the following case as lazy loading
```
import { NonLazyLoadedModule } from './non-lazy-loaded/non-lazy-loaded.module';
export function getNonLazyLoadedModule() { return NonLazyLoadedModule; }
export const routes = [
{ path: '/some-path', loadChildren: getNonLazyLoadedModule }
];
```
The output of the check is later passed to `RouteDef.fromString()`, so, it makes sense to be only a string.

- remove outer `<div>` in tests,
- use `<ng-container>` instead of `<template>` where possible,
- use *... instead of template (tag or attr) where possible.
Fixes#13816
With this change the resolver is called when the parameter for the activated and any parent routes change.
ie, switching from `/teams/10/players/5` to `/teams/12/players/5` will now trigger any `PlayerResolver`.
CHANGES:
- Remove unused `onDestroy` method on the `KeyValueDiffer` and
`IterableDiffer`.
DEPRECATION:
- `CollectionChangeRecord` is renamed to `IterableChangeRecord`.
`CollectionChangeRecord` is aliased to `IterableChangeRecord` and is
marked as `@deprecated`. It will be removed in `v5.x.x`.
- Deprecate `DefaultIterableDiffer` as it is private class which
was erroneously exposed.
- Deprecate `KeyValueDiffers#factories` as it is private field which
was erroneously exposed.
- Deprecate `IterableDiffers#factories` as it is private field which
was erroneously exposed.
BREAKING CHANGE:
- `IterableChangeRecord` is now an interface and parameterized on `<V>`.
This should not be an issue unless your code does
`new IterableChangeRecord` which it should not have a reason to do.

This change adds Compiler CLI support for any level of nesting for lazy routes.
For example `{app-root}/lazy-loaded-module-1/lazy-loaded-module-2/lazy-loaded-module-3`
Where `lazy-loaded-module-3` is lazy loaded from `lazy-loaded-module-2`,
and `lazy-loaded-module-2` is lazy loaded from module `lazy-loaded-module-1`,
and `lazy-loaded-module-1` is lazy loaded from `AppModule`

This was done in order for us to be able to publish tsc-wrapped as @next tag on npm.
The next step is to change the build scripts to version and release @angular/tsc-wrapped
together with all the other packages. I'll create an issue/PR for this.
@angular/language-service now supports using TypeScript 2.1 as the
the TypeScript host. TypeScript 2.1 is now also partially supported
in `ngc` but is not recommended as Tsickle does not yet support 2.1.
Detailed changes:
- remove `UNINITIALIZED`, initialize change detection fields with `undefined`.
* we use `view.numberOfChecks === 0` now everywhere
as indicator whether we are in the first change detection cycle
(previously we used this only in a couple of places).
* we keep the initialization itself as change detection get slower without it.
- remove passing around `throwOnChange` in various generated calls,
and store it on the view as property instead.
- change generated code for bindings to DOM elements as follows:
Before:
```
var currVal_10 = self.context.bgColor;
if (jit_checkBinding15(self.throwOnChange,self._expr_10,currVal_10)) {
self.renderer.setElementStyle(self._el_0,'backgroundColor',((self.viewUtils.sanitizer.sanitize(jit_21,currVal_10) == null)? null: self.viewUtils.sanitizer.sanitize(jit_21,currVal_10).toString()));
self._expr_10 = currVal_10;
}
var currVal_11 = jit_inlineInterpolate16(1,' ',self.context.data.value,' ');
if (jit_checkBinding15(self.throwOnChange,self._expr_11,currVal_11)) {
self.renderer.setText(self._text_1,currVal_11);
self._expr_11 = currVal_11;
}
```,
After:
```
var currVal_10 = self.context.bgColor;
jit_checkRenderStyle14(self,self._el_0,'backgroundColor',null,self._expr_10,self._expr_10=currVal_10,false,jit_21);
var currVal_11 = jit_inlineInterpolate15(1,' ',self.context.data.value,' ');
jit_checkRenderText16(self,self._text_1,self._expr_11,self._expr_11=currVal_11,false);

With the exception of `$onChanges()`, all lifecycle hooks in ng1 are called on
the controller, regardless if it is the binding destination or not (i.e.
regardless of the value of `bindToController`).
This change makes `upgrade` mimic that behavior when calling lifecycle hooks.
Additionally, calling the `$onInit()` hook has been moved before calling the
linking functions, which also mimics the ng1 behavior.
Note: This checks the constructors of `@Injectable` classes more strictly.
E.g this will fail now as the constructor argument has no `@Inject` nor is
the type of the argument a DI token.
```
@Injectable()
class MyService {
constructor(dep: string) {}
}
```

Fix an issue in `registerForNg1Tests`, where it passes a `null` as
`ng1Injector` to `_bootstrapDone`. This causes a "TypeError: Cannot
read property 'get' of null" to be thrown from `_bootstrapDone`.
This change retracts support for metadata version 2.
The collector used to produce version 2 metadata was incomplete
and can cause the AOT compiler to fail to resolve symbols or
produce other spurious errors.
All libraries compiled and published with 2.3.0 ngc will need
to be recompiled and updated with this change.
- New method `UpgradeAdapter.registerForNg1Tests(modules)` declares the
Angular 1 upgrade module and provides it to the `angular.mock.module()`
helper.
This prevents the need to bootstrap the entire hybrid for every test.

feat(tsc-wrapped): recored when to quote a object literal key
Collecting quoted literals is off by default as it introduces
a breaking change in the .metadata.json file. A follow-up commit
will address this.
Fixes#13249Closes#13356
If you bound an array to select[multiple] via ngModel and subsequently
changed the options to select from, the UI would drop any selections
made since by the user. This was due to
SelectMultipleControlValueAccessor not keeping a reference to the new
model arrays it generated when users interacted with the select control.
Update code to keep the reference.
Closes#12527Closes#12654
When an invalid model value (eg empty string) was preset ngModel on
select[multiple] would throw an error, which is inconsistent with how it
works on other user input elements. Setting the model value to null or
undefined would also have no effect on what was already selected in the
UI. Fix this by clearing selected options when model set to null,
undefined or a type other than Array.
Closes#11926
The existing intl.ts file is not a facade but
rather a set of utils used by i18n-related pipes only.
As such moving it back to common module so those utils
are not used accidently from other places.
NgIf syntax has been extended to support else clause to display template
when the condition is false. In addition the condition value can now
be stored in local variable, for later reuse. This is especially useful
when used with the `async` pipe.
Example:
```
<div *ngIf="userObservable | async; else loading; let user">
Hello {{user.last}}, {{user.first}}!
</div>
<template #loading>Waiting...</template>
```

When compiling libraries, this feature extracts the minimal information
from the directives/pipes/modules of the library into `.ngsummary.json` files,
so that applications that use this library only need to be recompiled
if one of the summary files change, but not on every change
of the libraries (e.g. one of the templates).
Only works if individual codegen for libraries is enabled,
see the `generateCodeForLibraries: false` option.
Closes#12787
Removes `CompileIdentifierMetadata.name` / `.moduleUrl`,
as well as `CompileTypeMetadata.name / moduleUrl` and
`CompileFactoryMetadata.name / moduleUrl`.
## Inheritance Semantics:
Decorators:
1) list the decorators of the class and its parents in the ancestor first order
2) only use the last decorator of each kind (e.g. @Component / ...)
Constructor parameters:
If a class inherits from a parent class and does not declare
a constructor, it inherits the parent class constructor,
and with it the parameter metadata of that parent class.
Lifecycle hooks:
Follow the normal class inheritance model,
i.e. lifecycle hooks of parent classes will be called
even if the method is not overwritten in the child class.
## Example
E.g. the following is a valid use of inheritance and it will
also inherit all metadata:
```
@Directive({selector: 'someDir'})
class ParentDirective {
constructor(someDep: SomeDep) {}
ngOnInit() {}
}
class ChildDirective extends ParentDirective {}
```

The change looks bigger than it really is because I reordered the properties to match other tsconfigs we have.

* With non-static ngUpgrade apps, callbacks to `whenStable` were being invoked with the wrong
context
* With non-static ngUpgrade apps, `resumeBootstrap` was being run outside the NgZone
* Remove redundent `whenStableContext` variable
Neither of the first two problems were actually causing bugs (as far as I know), but they *might*
have caused problems in the future.
Inspired by https://github.com/angular/angular/pull/12910, but for non-static apps.
- `NgHost` to `CompilerHost`
- `AotCompilerHost.resolveFileToImport` to `AotCompilerHost.fileNameToModuleName`
- `AotCompilerHoset.resolveImportToFile` to `AotCompilerHost.moduleNameToFileName`
This is needed to resolve symbols without `.d.ts` files.
This bumps the version of the metadata from 1 to 2.
This adds logic into `ng_host.ts` to automatically upgrade
version 1 to version 2 metadata by adding the exported symbols
from the `.d.ts` file.
Prior to this commit, translations were built in the serializers. This
could not work as a single translation can be used for different source
messages having different placeholder content.
Serializers do not try to replace the placeholders any more.
Placeholders are replaced by the translation bundle and the source
message is given as parameter so that the content of the placeholders is
taken into account.
Also XMB ids are now independent of the expression which is replaced by
a placeholder in the extracted file.

This improves ergonomics a bit by allowing people to write:

This patch ensures that animations are run outside of change detection
thus allowing for start and done callbacks to modify application data
without causing a cycle loop.
Closes#12713
Add support for the `$postDigest()` and `$onDestroy()` lifecycle hooks.
Better align the behavior of the `$onChanges()` and `$onInit()` lifecycle hooks
with Angular 1.x:
- Call `$onInit()` before pre-linking.
- Always instantiate the controller before calling `$onChanges()`.
Previously, if a `TemplateRef` was created in a `ViewContainerRef`
at a different place, the content was not query able at all.
With this change, the content of the template can be queried
as if it was stamped out at the declaration place of the template.
E.g. in the following example, the `QueryList<ChildCmp>` will
be filled once the button is clicked.
```
@Component({
selector: ‘my-comp’,
template: ‘<button #vc (click)=“createView()”></button>’
})
class MyComp {
@ContentChildren(ChildCmp)
children: QueryList<ChildCmp>;
@ContentChildren(TemplateRef)
template: TemplateRef;
@ViewChild(‘vc’, {read: ViewContainerRef})
vc: ViewContainerRef;
createView() {
this.vc.createEmbeddedView(this.template);
}
}
@Component({
template: `
<my-comp>
<template><child-cmp></child-cmp></template>
</my-comp>
`
})
class App {}
```

But use the DOM apis directly.
This also creates a separate `ServerRenderer` implementation
for `platform-server` as it previously reused the `BrowserRenderer`.
This fixes a performance regressions introduced by 178fb79b5c.
Also makes properties in the directive wrapper private
so that closure compiler can minify them better.
Bash scripts create and tear down symlinks on Windows. These use the

Part of #11683
This commit introduces a new API to the ngUpgrade module, which is compatible
with AoT compilation. Primarily, it removes the dependency on reflection
over the Angular 2 metadata by introducing an API where this information
is explicitly defined, in the source code, in a way that is not lost through
AoT compilation.
This commit is a collaboration between @mhevery (who provided the original
design of the API); @gkalpak & @petebacondarwin (who implemented the
API and migrated the specs from the original ngUpgrade tests) and @alexeagle
(who provided input and review).
This commit is an starting point, there is still work to be done:
* add more documentation
* validate the API via internal projects
* align the ngUpgrade compilation of A1 directives closer to the real A1
compiler
* add more unit tests
* consider support for async `templateUrl` A1 upgraded components
Closes#12239
`normalizeMethodName` reflectively accessed the RequestMethod enum. With a smart
optimizer, properties from the enum could be removed or renamed, and so user
code just passing in e.g. 'PATCH' might not work. This change fixes the code to
be more explicit and avoids the optimizer issue.
Either bind an expression or use the attribute notation.
The mixed way `[routerLink]="/path"` won't work.
Prefer the attribute notation for string-only paths
* feat(forms): ngSubmit event exposes $event from original submit event as local variable

This resolves#10920.
* refactor: code cleanup
* docs(changelog): fix mentions and backticks
`@page` and `@document` were both incorrectly linking to GitHub repositories.
`:enter` and `:leave` in the *Features* section were missing backticks.

Modify routerLinkActive to optimise performance by removing unnecessary iteration. By replacing Array.reduce with Array.some, the loop will break when it finds an active link. Useful if used on the parent of a large group of routerLinks. Furthermore, if a RouterLink is active it will not check the RouterLinkWithHrefs.
The `addProvider` function in the `UpgradeAdapter` was deprecated in this [commit](d21331e902 (diff-77163e956a7842149f583846c1c01651)) and has been removed in final. Given this, the documentation for downgrading ng2 providers for use in ng1 is invalid.

Instead of using a variable for the link of browserstack it was using the direct https link.
That caused to show the text and the link (incorrect markdown).
Moved the https link to the bottom with the other link assignments. It will now only show the blue text with the link to the browserstack.
BREAKING CHANGE:
- all `…Metadata` classes have been removed. Use the corresponding decorator
as constructor or for `instanceof` checks instead.
- Example:
* Before: `new ComponentMetadata(…)`
* After: `new Component(…)`
- Note: `new Component(…)` worked before as well.
Every decorator now is made of the following:
- a function that can be used
as a decorator or as a constructor. This function
also can be used for `instanceof` checks.
- a type for this function (callable and newable)
- a type that describes the shape of the data
that the user needs to pass to the decorator
as well as the instance of the metadata
The docs for decorators live at the followig places
so that IDEs can discover them correctly:
- General description of the decorator is placed on the
`...Decorator` interface on the callable function
definition
- Property descriptions are placed on the interface
that describes the metadata produces by the decorator
* chore: update protractor and selenium-webdriver packages
As `karma-jasmine` has a peer dependency on `jasmine-core@2.3`, but `jasmine` and `protractor` are using `jasmine-core@2.4` we need to add `jasmine-core@2.3` explicitly. Previously, the peer dependency was
satisfied by accident because npm deduped the dependency
for `jasmine-core@2.3` as top level dependency.
Note that the shrink-wrap files changes quite a bit because
of the deduping mechanism of npm.

When lazily loading code, users need to be able to get hold of the
NgModuleFactory. For SystemJS environments, the SystemJS registry serves
this purpose. However other environments, such as modules compiled with
Closure compiler, do not expose exports object or a path based registry.
For these environments, `@NgModule` objects can include an identifier, and
the loading code can then pass `loadModule(id).then(() =>
getNgModule(id))` to the router.

Before the change:
// original CSS
:host .foo .bar {...}
.foo .bar {...}
// translated to
[_nghost-shh-2] .foo .bar {...}
.foo[_ngcontent-shh-2] .bar[_ngcontent-shh-2] {...}
Note that `.foo` and `.bar` where not scoped and would then apply to nested components.
With this change those selectors are scoped (as they are without `:host`).
You can explicitly apply the style to inner component by using `>>>` or `/deep/`: `:host >>> .foo`
BREAKING CHANGE:
Exceptions are no longer part of the public API. We don't expect that anyone should be referring to the Exception types.
ExceptionHandler.call(exception: any, stackTrace?: any, reason?: string): void;
change to:
ErrorHandler.handleError(error: any): void;
BREAKING CHANGES:
- `#` and `var` are not supported any more in expressions, use `let`,
- `var-<name>` could not be used any more on templates, use `let-<name>`,
- `var-<name>` could not be used any more to create a reference, use `ref-<name>`.
Accessing a property on the window object must be done with square brackets.
Otherwise closure compiler may collide the symbol's alias between the property
and variable mappings.
Also, accessing the 'provide' property must be done with dot syntax, so that
it can be renamed along with the code that declares such a property.
BREAKING CHANGE: previously deprecated @Component.directives and @Component.pipes support was removed.
All the components and pipes now must be declarated via an NgModule. NgModule is the basic
compilation block passed into the Angular compiler via Compiler#compileModuleSync or #compileModuleAsync.
Because of this change, the Compiler#compileComponentAsync and #compileComponentSync were removed as well -
any code doing compilation should compile module instead using the apis mentioned above.
Lastly, since modules are the basic compilation unit, the ngUpgrade module was modified to always require
an NgModule to be passed into the UpgradeAdapter's constructor - previously this was optional.
ngc can now validate metadata before emitting to verify it doesn't
contain an error symbol that will result in a runtime error if
it is used by the StaticReflector.
To enable this add the section,
"angularCompilerOptions": {
"strictMetadataEmit": true
}
to the top level of the tsconfig.json file passed to ngc.
Enabled metadata validation for packages that are intended to be
used statically.
Until we have comprehensive E2E tests, it's too risky to change the
reflector_host Misko wrote before final. But google3 uses path mapping
and needs all imports to be and all paths to be canonicalized to
the longest rootDir.
This change introduces a subclass of ReflectorHost with overrides for methods
that differ. After final (or when we have good tests), we'll refactor
them back into one class.
Often it is useful to test a component without rendering certain directives/components
in its template because these directives require some complicated setup.
You can do that by using NO_ERRORS_SCHEMA.
TestBed.configureTestingModule({
schemas: [NO_ERRORS_SCHEMA]
});
This would disable all schema checks in your tests.
Closes#10503
It is possible for code in `beforeEach` to capture and fork a zone
(for example creating `NgZone` in `beforeEach`). Subsequently the code
in `it` may chose to do `fakeAsync`. The issue is that because the
code in `it` can use `NgZone` from the `beforeEach`. it effectively can
escape the `fakeAsync` zone. A solution is to run all of the test in
`ProxyZone` which allows a test to dynamically replace the rules at any
time. This allows the `beforeEach` to fork a zone, and then `it` to
retroactively became `fakeAsync` zone.
When creating a new Headers object using an existing Headers object
the existing Headers map is copied by reference. Therefore adding a
new Header value to the new Headers object also added this value to
the existing Headers object which is not in accordance with the
spec.
This commit alters the constructor to create a deep copy of existing
Headers maps and therefore unlink existing Headers from new Headers.
Closes#6845
BREAKING CHANGE:
any code which relies on the fact that a newly
created Headers object is referencing an existing Headers map is
now broken, but that should normally not be the case since this
behavior is not documented and not in accordance with the spec.
BREAKING CHANGE: Animations defined using an at-symbol prefix that are
not property bound are now invalid.

Remove test setup functions which were deprecated in rc5. See the
changelog for rc5 for how to update. In brief, instead of
`setBaseTestProviders`, use `TestBed.initTestEnvironment`.
We changed the bootstrap order:
1. create NgZone
2. bootstrap ng1 inside NgZone and upgrade ng1 components to ng2 components.
3. bootstrap ng2 with NgZone
Note: Previous footgun behavior was: bootstrap ng2 first to extract NgZone, so that ng1 bootstrap can happen in NgZone. This meant that if ng2 bootstrap eagerly compiled a component which contained ng1 components, then we did not have complete metadata.
BREAKING CHANGE: UpgradeAdapter.addProvider are now deprecated in favor of passing in an NgModule into the adapter's constructor
Before:
```
let upgradeAdapter = new UpgradeAdapter();
upgradeAdapter.addProviders([myProvidersArray);
```
After:
```
@NgModule({
providers: myProvidersArray
})
class MyModule {}
let upgradeAdapter = new UpgradeAdapter(MyModule);
```
Currently in the `linker/compiler.ts` file, the **same identifier** is used in **two declarations**:
```typescript
export type CompilerOptions = { … }
…
export const CompilerOptions = new OpaqueToken('compilerOptions');
```
This breaks the API doc generation. I’m surprised that this was not flagged by the tsc.
The duplicate declaration was introduced in 46b212706b.
Prior to this change `ngc` would place generated files which refer
to components in the node_modules into the node_module. This is an
issue. Now all of the files are forced into a single directory
as specified in `tsconfig.json` by the `genDir` option.
see: https://docs.google.com/document/d/1OgP1RIpZ-lWUc4113J3w13HTDcW-1-0o7TuGz0tGx0g
Because
- `Form` is **exported** -- see line 30/31 of
`modules/@angular/forms/src/forms.ts`: i.e., <br>`export {Form} from
'./directives/form_interface'`; and
- Methods of `Form`, which are public, have an
`AbstractFormGroupDirective` parameter;
e.g.,<br>`Form.getFormGroup(dir: AbstractFormGroupDirective):
FormGroup`.
Then it makes sense for `AbstractFormGroupDirective` to be
public/exported too. In any case, if it isn't exported then the **API
docs for `Form` don't get generated properly.**
BREAKING CHANGE:
- `ApplicationRef.run` is deprecated. Use `NgZone.run` directly
- `ApplicationRef.injector` is deprecated. Inject an `Injector` or
use `NgModuleRef.injector` instead
- `ApplicationRef.zone` is deprecated. Inject `NgZone` instead.
`ApplicationRef.bootstrap` is supposed to be run inside of `ngDoBootstrap` method
of the module that is bootstrapped, and that method already runs inside of the
zone.
This class allows any provider to know and wait for the initialization of the
application. This functionality previously was tied to `ApplicationRef`.
BREAKING CHANGE:
- `ApplicationRef.waitForAsyncInitializers` is deprecated. Use
`AppInitStatus.donePromise` / `AppInitStatus.done` instead.
If a `@NgModule` has a `bootstrap` property, `PlatformRef.bootstrapModule` /
`PlatformRef.bootstrapModuleFactory` will automatically bootstrap the components
listed in there.
If such a property does not exist, `PlatformRef.bootstrapModule` /
`PlatformRef.bootstrapModuleFactory` will try to call the method `ngDoBootstrap(appRef: ApplicationRef)` on the module class.
Otherwise an error is reported.
Using the `registerBootstrapListener` easily lead to race condition
and needed dependencies on `ApplicationRef`.
BREAKING CHANGE:
- `ApplicationRef.registerBootstrapListener` is deprecated. Provide a multi
provider for the new token `APP_BOOTSTRAP_LISTENER` instead.
Note about the addition of `beforeEach(fakeAsync(inject(…))))` in some tests:
`ApplicationRef` is now using `ngOnDestroy` and there is eager,
including all of its dependencies which contain `NgZone`.
The additional `fakeAsync` in `beforeEach` ensures that `NgZone`
uses the fake async zone as parent, and not the root zone.
BREAKING CHANGE (via deprecations):
- `ApplicationRef.dispose` is deprecated. Destroy the module that was
created during bootstrap instead by calling `NgModuleRef.destroy`.
- `AplicationRef.registerDisposeListener` is deprecated.
Use the `ngOnDestroy` lifecycle hook for providers or
`NgModuleRef.onDestroy` instead.
- `disposePlatform` is deprecated. Use `destroyPlatform` instead.
- `PlatformRef.dipose()` is deprecated. Use `PlatformRef.destroy()`
instead.
- `PlatformRef.registerDisposeListener` is deprecated. Use
`PlatformRef.onDestroy` instead.
- `PlaformRef.diposed` is deprecated. Use `PlatformRef.destroyed`
instead.
This is needed for the case if a `beforeEach` instantiates
`NgZone`and the `it` uses
`TestComponentBuilder.createFakeAsync`.
Otherwise the `NgZone` will use the root zone as parent,
and `TestComponentBuilder.createFakeAsync` will always return
undefined as `tick` does not forward promises created
under the zone of `NgZone`.
This makes `bootstrapModuleFactory` wait for promises
returned by `APP_INITIALIZER`s, also making `bootstrapModuleFactory` async.
I.e. now `bootstrapModule` and `bootstrapModuleFactory` behave in the
same way.
This ensures that all code from module instantiation, to creating
`ApplicationRef`s as well as calling `APP_INITIALIZERS` is run
in the Angular zone.
This also moves the invocation of the initializers from the `ApplicationRef`
constructor into the `bootstrapModuleFactory` call, allowing initializers
to get a hold of `ApplicationRef` (see #9101).
Fixes#9101Fixes#10363Fixes#10205
The methods on `ViewResolverMock` have been merged into `DirectiveResolver`.
BREAKING CHANGE:
- ES5 users can no longer use the `View(…)` function to provide `ViewMetadata`.
This mirrors the removal of the `@View` decorator a while ago.
Prior to this fix [ngClass] would remove all dynamic classes
when destroyed. It's essential that classes are persisted such
that remove-based animations will still be stylistically correct.
This patch fixes this issue.
Closes#10008Closes#10303
Previously, Angular would warn users when simply re-encoding text
outside of the ASCII range. While harmless, the log spam was annoying.
With this change, Angular specifically tracks whether anything was
stripped during sanitization, and only reports a warning if so.
Fixes#10206.
BREAKING CHANGES:
- `browserPlatform`/`browserDynamicPlatform`/... have been deprecated and renamed into `platformBrowser`/`platformBrowserDynamic`/....
- `bootstrapModule` and `bootstrapModuleFactory` have been moved to be members of `PlaformRef`.
E.g. `platformBrowserDynamic().bootstrapModule(MyModule)`.
This allows Angular to error on unknown properties,
allowing applications that don’t use custom elements
to get better error reporting.
Part of #10043
BREAKING CHANGE:
- By default, Angular will error during parsing
on unknown properties,
even if they are on elements with a `-` in their name
(aka custom elements). If you application is using
custom elements, fill the new parameter `@NgModule.schemas`
with the value `[CUSTOM_ELEMENTS_SCHEMA]`.
E.g. for bootstrap:
```
bootstrap(MyComponent, {schemas: [CUSTOM_ELEMENTS_SCHEMA]});
```
Part of #10043
BREAKING CHANGE:
- `@Component.precompile` was renamed to `@Component.entryComponents`
(old property still works but is deprecated)
- `ANALYZE_FOR_PRECOMPILE` was renamed to `ANALYZE_FOR_ENTRY_COMPONENTS` (no deprecations)
This contains major changes to the compiler, bootstrap of the platforms
and test environment initialization.
Main part of #10043Closes#10164
BREAKING CHANGE:
- Semantics and name of `@AppModule` (now `@NgModule`) changed quite a bit.
This is actually not breaking as `@AppModules` were not part of rc.4.
We will have detailed docs on `@NgModule` separately.
- `coreLoadAndBootstrap` and `coreBootstrap` can't be used any more (without migration support).
Use `bootstrapModule` / `bootstrapModuleFactory` instead.
- All Components listed in routes have to be part of the `declarations` of an NgModule.
Either directly on the bootstrap module / lazy loaded module, or in an NgModule imported by them.
Some test cases incorrectly rely on the side effect of other test cases
importing `NgMatchers`. This commit fixes this by making `expect` in
`core/testing_internal` properly typed.
Resource URLs are strictly "more" trustworthy than plain URLs, so trusting them maintains the same level of security while avoiding to break people when we downgrade a resource URL context to a plain URL context.
BREAKING CHANGE
Previously both imperative (router.navigate) and declarative (routerLink) navigations
would preserve the current query params and fragment. This behavior turned out to
be confusing. This commit changes it.
Now, neither is preserved by default. To preserve them, you need to do the following:
router.naviage("newUrl", {preserveQueryParams: true, preserveFragment: true})
<a routerLink="newUrl" preserveQueryParams preserveFragment></a>
This removes the magic from the `inject` test helper that would inspect
the current zone and would only work with our `async` test helper.
Now, `inject` is always synchronous, and if you are using a module
that requires async precompilation, you're required to call
`doAsyncPrecompilation` in your tests.
This is part of the breaking changes introduced with the swap
to each test having an AppModule.
Closes#9975Closes#9593
BREAKING CHANGE:
`TestInjector` is now renamed to `TestBed`
Before:
```js
import {TestInjector, getTestInjector} from '@angular/core/testing';
```
After:
```js
import {TestBed, getTestBed} from '@angular/core/testing';
```
Due to daa9da4047,
tests using the setBaseTestProviders stopped working with ambient directives such as
`ngIf`. Add them back in to keep the shim working.
This remove a breaking change introduced with commit #e7a8e2757b06d572f614f53b648d2fd75df370d2 where json objects passed to requests were not converted into string.
BREAKING CHANGE:
The behavior in this commit is the same as before PR 7260 : the objects sent with the request are converted to a string, therefore there is no need for the user to take care of the serialization.
Fixes#10073
The testing_e2e util does not belong in platform-browser and was never
intended to be a public API. Move it out of that whole tree.
BREAKING CHANGE:
The following API was never intended to be public and is removed:
```js
import {verifyNoBrowserErrors} from '@angular/platform-browser/testing_e2e';
```
Consider using Protractor's console plugin: https://github.com/angular/protractor-console-plugin
BREAKING CHANGES:
"{" is used a a delimiter for ICU messages then it could not be used in text nodes.
"{" should be escaped as "{{ '{' }}"
Before:
<span>some { valid } text</span>
After:
<span>some { invalid } text<span> <!-- throw parse error -->
<span>some {{ '{' }} valid } text</span>
This change reverts the removal of setBaseTestProviders that was
introduced in 8d746e3f67.
Instead, setBaseTestProviders and the providers provided from
`@angular/platform-browser-dynamic/testing` and `@angular/server/testing`
will still work for the next release, but are deprecated.
See 8d746e3f67 for how to upgrade.
BREAKING CHANGE (deprecations)
- Instead of `coreBootstrap`, create an `@AppModule` and use `bootstrapModule`.
- Instead of `coreLoadAndBootstarp`, create an `@AppModule` and use `bootstrapModuleFactory`.
- Instead of `bootstrapWorkerApp`, create an `@AppModule` that includes the `WorkerAppModule` and use `bootstrapModule` with the `workerAppPlatform()`.
- Instead of `bootstrapWorkerUi`, create an @AppModule that includes the `WorkerUiModule` and use `bootstrapModule` with the `workerUiPlatform()` instead.
- Instead of `serverBootstrap`, create an @AppModule and use `bootstrapModule` with the `serverDynamicPlatform()` instead.
- Instead of `PLATFORM_PIPES` and `PLATFORM_DIRECTIVES`, provide platform directives/pipes via an `@AppModule`.
- Instead of `ComponentResolver`:
- use `ComponentFactoryResolver` together with `@AppModule.precompile`/`@Component.precompile` or `ANALYZE_FOR_PRECOMPILE` provider for dynamic component creation.
- use `AppModuleFactoryLoader` for lazy loading.
- Instead of `SystemJsComponentResolver`, create an `@AppModule` and use `SystemJsAppModuleLoader`.
- Instead of `SystemJsCmpFactoryResolver`, create an `@AppModule` and use `SystemJsAppModuleFactoryLoader`
Closes#9726
- Introduces `CompilerFactory` which can be part of a `PlatformRef`.
- Introduces `WorkerAppModule`, `WorkerUiModule`, `ServerModule`
- Introduces `serverDynamicPlatform` for applications using runtime compilation
on the server.
- Changes browser bootstrap for runtime and offline compilation (see below for an example).
* introduces `bootstrapModule` and `bootstrapModuleFactory` in `@angular/core`
* introduces new `browserDynamicPlatform` in `@angular/platform-browser-dynamic
- Changes `initTestEnvironment` (which used to be `setBaseTestProviders`) to not take a compiler factory any more (see below for an example).
BREAKING CHANGE:
## Migration from `setBaseTestProviders` to `initTestEnvironment`:
- For the browser platform:
BEFORE:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS} from ‘@angular/platform-browser-dynamic/testing’;
setBaseTestProviders(TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,

import {browserDynamicTestPlatform,
BrowserDynamicTestModule} from ‘@angular/platform-browser-dynamic/testing’;
initTestEnvironment(
BrowserDynamicTestModule,

```
- For the server platform:
BEFORE:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {TEST_SERVER_PLATFORM_PROVIDERS,
TEST_SERVER_APPLICATION_PROVIDERS} from ‘@angular/platform-server/testing/server’;
setBaseTestProviders(TEST_SERVER_PLATFORM_PROVIDERS,
TEST_SERVER_APPLICATION_PROVIDERS);
```
AFTER:
```

Closes#9922
Part of #9726
We still support this via a hack, but should remove this soon.
This also fixes tests for module directives / pipes
as they used directives / pipes that were
already present in the underlying platform.
Animation triggers can now be set via template bindings `[]`
BREAKING CHANGE:
animation trigger expressions within the template that are assigned as
an element attribute (e.g. `@prop`) are deprecated. Please use the
Angular2 property binding syntax (e.g. `[@prop]`) when assigning
properties.
```ts
// this is now deprecated
<div @trigger="expression"></div>
// do this instead
<div [@trigger]="expression"></div>
```
Introduces the new `ANALYZE_FOR_PRECOMPILE` token. This token can be used to
create a virtual provider that will populate the `precompile` fields of
components and app modules based on its
`useValue`. All components that are referenced in the `useValue`
value (either directly or in a nested array or map) will be added
to the `precompile` property.
closes#9874
related to #9726
Closes#9732
BREAKING CHANGE:
We have removed the deprecated form directives from the built-in platform directive list, so apps are not required to package forms with their app. This also makes forms friendly to offline compilation.
Instead, we have exposed three modules:
OLD API:
- `DeprecatedFormsModule`
NEW API:
- `FormsModule`
- `ReactiveFormsModule`
If you provide one of these modules, the default forms directives and providers from that module will be available to you app-wide. Note: You can provide both the `FormsModule` and the `ReactiveFormsModule` together if you like, but they are fully-functional separately.
**Before:**
```ts
import {disableDeprecatedForms, provideForms} from @angular/forms;
bootstrap(App, [
disableDeprecatedForms(),
provideForms()
]);
```
**After:**
```ts
import {DeprecatedFormsModule} from @angular/common;
bootstrap(App, {modules: [DeprecatedFormsModule] });
```
-OR-
```ts
import {FormsModule} from @angular/forms;
bootstrap(App, {modules: [FormsModule] });
```
-OR-
```ts
import {ReactiveFormsModule} from @angular/forms;
bootstrap(App, {modules: [ReactiveFormsModule] });
```
You can also choose not to provide any forms module and run your app without forms.
Or you can choose not to provide any forms module *and* provide form directives at will. This will allow you to use the deprecatedForms API for some components and not others.
```
import {FORM_DIRECTIVES, FORM_PROVIDERS} from @angular/forms;
@Component({
selector: some-comp,
directives: [FORM_DIRECTIVES],
providers: [FORM_PROVIDERS]
})
class SomeComp
```
Every test now has an implicit module. It can be configured via `configureModule` (from @angular/core/testing)
to add providers, directives, pipes, ...
The compiler now has to be configured separately via `configureCompiler` (from @angular/core/testing)
to add providers or define whether to use jit.
BREAKING CHANGE:
- Application providers can no longer inject compiler internals (i.e. everything
from `@angular/compiler). Inject `Compiler` instead. This reflects the
changes to `bootstrap` for module support (3f55aa609f).
- Compiler providers can no longer be added via `addProviders` / `withProviders`.
Use the new method `configureCompiler` instead.
- Platform directives / pipes need to be provided via
`configureModule` and can no longer be provided via the
`PLATFORM_PIPES` / `PLATFORM_DIRECTIVES` tokens.
- `setBaseTestProviders()` was renamed into `initTestEnvironment` and
now takes a `PlatformRef` and a factory for a
`Compiler`.
- E.g. for the browser platform:
BEFORE:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS} from ‘@angular/platform-browser-dynamic/testing’;
setBaseTestProviders(TEST_BROWSER_DYNAMIC_PLATFORM_PROVIDERS,
TEST_BROWSER_DYNAMIC_APPLICATION_PROVIDERS);
```
AFTER:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {browserTestCompiler, browserDynamicTestPlatform,
BrowserDynamicTestModule} from ‘@angular/platform-browser-dynamic/testing’;
initTestEnvironment(
browserTestCompiler,
browserDynamicTestPlatform(),
BrowserDynamicTestModule);
```
- E.g. for the server platform:
BEFORE:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {TEST_SERVER_PLATFORM_PROVIDERS,
TEST_SERVER_APPLICATION_PROVIDERS} from ‘@angular/platform-server/testing/server’;
setBaseTestProviders(TEST_SERVER_PLATFORM_PROVIDERS,
TEST_SERVER_APPLICATION_PROVIDERS);
```
AFTER:
```
import {setBaseTestProviders} from ‘@angular/core/testing’;
import {serverTestCompiler, serverTestPlatform,
ServerTestModule} from ‘@angular/platform-browser-dynamic/testing’;
initTestEnvironment(
serverTestCompiler,
serverTestPlatform(),
ServerTestModule);
```

This introduces the `BrowserModule` to be used for long form
bootstrap and offline compile bootstrap:

providers: […], // additional providers
directives: […], // additional platform directives
pipes: […] // additional platform pipes
})
class MyModule {

}
}
// offline compile
import {bootstrapModuleFactory} from ‘@angular/platform-browser’;
bootstrapModuleFactory(MyModuleNgFactory);
// runtime compile long form
import {bootstrapModule} from ‘@angular/platform-browser-dynamic’;
bootstrapModule(MyModule);
```
The short form, `bootstrap(...)`, can now creates a module on the fly,
given `directives`, `pipes, `providers`, `precompile` and `modules`
properties.
Related changes:
- make `SanitizationService`, `SecurityContext` public in `@angular/core` so that the offline compiler can resolve the token
- move `AnimationDriver` to `platform-browser` and make it
public so that the offline compiler can resolve the token
BREAKING CHANGES:
- short form bootstrap does no longer allow
to inject compiler internals (i.e. everything
from `@angular/compiler). Inject `Compiler` instead.
To provide custom providers for the compiler,
create a custom compiler via `browserCompiler({providers: [...]})`
and pass that into the `bootstrap` method.
This implements a new class, QueryEncoder, that provides
methods for encoding keys and values of query parameter.
The encoder encodes with encodeURIComponent, and then
decodes a whitelist of allowed characters back to their
unencoded form.
BREAKING CHANGE:
The changes to Http's URLSearchParams serialization now
prevent encoding of these characters inside query parameters
which were previously converted to percent-encoded values:
@ : $ , ; + ; ? /
The default encoding behavior can be overridden by extending
QueryEncoder, as documented in the URLSearchParams service.
Fixes#9348
Adds new abstraction `Compiler` with methods
`compileComponentAsync` and `compileComponentSync`.
This is in preparation of deprecating `ComponentResolver`.
`compileComponentSync` is able to compile components
synchronously given all components either have an inline
template or they have been compiled before.
Also changes `TestComponentBuilder.createSync` to
take a `Type` and use the new `compileComponentSync` method.
Also supports overriding the component metadata even if
the component has already been compiled.
Also fixes#7084 in a better way.
BREAKING CHANGE:
`TestComponentBuilder.createSync` now takes a component type
and throws if not all templates are either inlined
are compiled before via `createAsync`.
Closes#9594

Instead, the async function now determines whether it should return a promise
or instead call a done function parameter. Importing Jasmine functions
from `@angular/core/testing` is no longer necessary and is now deprecated.
Additionally, beforeEachProviders is also deprecated, as it is specific
to the testing framework. Instead, use the new addProviders method directly.
Before:
```js
import {beforeEachProviders, it, describe, inject} from 'angular2/testing/core';
describe('my code', () => {
beforeEachProviders(() => [MyService]);
it('does stuff', inject([MyService], (service) => {
// actual test
});
});
```
After:
```js
import {addProviders, inject} from 'angular2/testing/core';
describe('my code', () => {
beforeEach(() => {
addProviders([MyService]);
});
it('does stuff', inject([MyService], (service) => {
// actual test

});
```
TestComponentBuilder now lives in core/testing. compiler/testing contains a private
OverridingTestComponentBuilder implementation which handles the private behavior
we need to override templates. This is part of the effort to simplify the testing
imports and hide compiler APIs.
Closes#9585
BREAKING CHANGE:
`TestComponentBuilder` is now imported from `@angular/core/testing`. Imports
from `@angular/compiler/testing` are deprecated.
Before:
```

```
After:
```
import {TestComponentBuilder, TestComponentRenderer, ComponentFixtureAutoDetect} from '@angular/core/testing';
```
BREAKING CHANGE:
MockLocationStrategy was intended to be internal only and is now removed
from the `@angular/common/testing` public api.
Use `SpyLocation` from `@angular/common/testing` for location testing.
BREAKING CHANGE:
`ComponentFixture` will be moving out of `@angular/compiler/testing` to `@angular/core/testing` in
this release. For now, it is deprecated from `@angular/compiler/testing`.
Previously, we were exporting internal mocks and helpers. Move these
to core/testing/testing_internal or remove them if they were
never used.
Remove deprecated items - injectAsync, clearPendingTimers.
BREAKING CHANGE:
Remove the following APIs from `@angular/core/testing`, which have been deprecated or were
never intended to be publicly exported:
```
injectAsync
clearPendingTimers
Log
MockAppliacationHref
MockNgZone
clearPendingTimers
getTypeOf
instantiateType
```
Instead of `injectAsync`, use `async(inject())`.
`clearPendingTimers` is no longer required.
Mostly, removing things that were never intended to be exported publicy.
BREAKING CHANGE:
The following are no longer publicly exported APIs. They were intended as internal
utilities and you should use your own util:
```
browserDetection,
dispatchEvent,
el,
normalizeCSS,
stringifyElement,
expect (and custom matchers for Jasmine)

BREAKING CHANGES:
Previously multiple template bindings on one element
(ex. `<div *ngIf='..' *ngFor='...'>`) were allowed but most of the time
were leading to undesired result. It is possible that a small number
of applications will see template parse errors that shuld be fixed by
nesting elements or using `<template>` tags explicitly.

not been bound (that is, don't have the parent property set).
Fixes#9182Fixes#9265
If a user ends up with a safe value in an interpolation context, that's probably
a bug. Returning `"SafeValue must use [property]= binding"` will make it easier
to detect and correct the situation. Detecting the situation and throwing an
error for it could cause performance issues, so we're not doing this at this
point (but might revisit later).
Part of #8511 and #9253.
This lets users continue using runtime-sideeffect Decorators if they choose,
only down-leveling the marked ones to Annotations.
Also remove the "skipTemplateCodegen" option, which is no longer needed
since Angular compiles with tsc-wrapped rather than ngc. The former doesn't
include any codegen.
"render" is gramatically incorrect and confusing to developers who used this api.
Since webworker apis were exposed only in master, renaming these before the rc2 release
is not a breaking change
`<ng-container>` is a logical container that can be used to group nodes but is not rendered in the DOM tree as a node.
`<ng-container>` is rendered as an HTML comment.

Previously these symbols were exposed via platform-browser-dynamic, then we merged then into platform-browser
thinking that tools would know how to shake off the compiler and other dynamic bits not used with the offline
compilation flow. This turned out to be wrong as both webpack and rollup don't have good enough tree-shaking
capabilities to do this today. We think that in the future we'll be able to merge these two entry points into
one, but we need to give tooling some time before we can do it. In the meantime the reintroduction of the -dynamic
package point allows us to separate the compiler dependencies from the rest of the framework.
This change undoes the previous breaking change that removed the platform-browser-dynamic package.
The collector now collects the body of functions that return an
expression as a symbolic 'function'. The static reflector supports
expanding these functions statically to allow provider macros.
Also added support for the array spread operator in both the
collector and the static reflector.
This aligns the configuration of platform pipes / directives with offline compilation.
BREAKING CHANGE:
- `PLATFORM_PIPES` and `PLATFORM_DIRECTIVES` now are fields on `CompilerConfig`.
Instead of providing a binding to these tokens, provide a binding for `CompilerConfig` instead.
The web animations API now requires that all styles are converted to
camel case. Chrome has already made this breaking change and hyphenated
styles are not functional anymore.

Fix#9130.
Refactored ReflectorHost to allow it to be tested.
Fixed an issue where the .d.ts was findable but it wasn't used by the project
(This happens when the .metadata.json file references a module that was not
needed, such as it doesn't declare any types, and the reference to it was
elided by TypeScript when writing the .d.ts file).
Added tests for ReflectorHost
Now that we have --noImplicitAny we don't need these checks for explicit types in specific locations.
Also re-enable the check to disallow keywords as variable names.

There is no need to expose this additional method inside of the Renderer

The issue came from a lack of support for backtracking on string
matching.
The way it is done, if the "end pattern" for consumeRawText starts with

Currently downgraded ng2 elements fail inside a ui-router view because they are unable
to require an ng2 Injector via the require attribute of the DDO, because ui-router compiles
its templates before they are inserted in a ui-view. This adds a "fallback" behavior if
a parent injector cannot be found to go to the root ng2 Injector.
Delays NG1 Directive controller instatiation where possible and pre-link function always
to the ngOnInit() lifecycle hook. This way bindings are always available on $scope in both
the controller and the link function.
Allows sanitized URLs for CSS properties. These can be abused for information
leakage, but only if the CSS rules are already set up to allow for it. That is,
an attacker cannot cause information leakage without controlling the style rules
present, or a very particular setup.
Fixes#8514.
Sanitizing style and URL values breaks specific patterns, see #8491 for
an example. This documents and acknowledges the breaking change while we
work on improving CSS sanitization to allow more values through.
This is based on Angular 1's implementation, parsing an HTML document
into an inert DOM Document implementation, and then serializing only
specifically whitelisted elements.
It currently does not support SVG sanitization, all SVG elements are
rejected.
If available, the sanitizer uses the `<template>` HTML element as an
inert container.
Sanitization works client and server-side.

the bundles have source mpas disabled for now because when we downlevel
the esm bundle to es5 tsc doesn't consider the original source map so
we end up with a source map pointing to the esm bundle instead which is
not useful.
Summary:
This adds basic security hooks to Angular 2.
* `SecurityContext` is a private API between core, compiler, and
platform-browser. `SecurityContext` communicates what context a value is used
in across template parser, compiler, and sanitization at runtime.
* `SanitizationService` is the bare bones interface to sanitize values for a
particular context.
* `SchemaElementRegistry.securityContext(tagName, attributeOrPropertyName)`
determines the security context for an attribute or property (it turns out
attributes and properties match for the purposes of sanitization).
Based on these hooks:
* `DomSchemaElementRegistry` decides what sanitization applies in a particular
context.
* `DomSanitizationService` implements `SanitizationService` and adds *Safe
Value*s, i.e. the ability to mark a value as safe and not requiring further
sanitization.
* `url_sanitizer` and `style_sanitizer` sanitize URLs and Styles, respectively
(surprise!).
`DomSanitizationService` is the default implementation bound for browser
applications, in the three contexts (browser rendering, web worker rendering,
server side rendering).

Fixes#8408
This bug was introduced not long ago by 152a117d5c
Also add a configuration switch to disable the codegen, so we can
still use the metadata emit and tsickle pre-processing in the
build pipeline for angular itself.
Before, we would create all fields in the generated views
with visibility `private`. This does not work if an embedded
view references a directive / element in a parent view.
In Dart, this was no problem so far as it does not have
a `private` modifier.
Before, `useValue` in a provider did not work when doing
offline compile, as so far the `MetadataResolver` was only
used for jit mode. Now, `useValue` supports any kind of value
that the static reflector can return. E.g. primitives,
arrays, string maps, …
Closes#8366
Most of the bugs discovered so far in the offline compiler were related to the StaticReflector. As it was part of angular2 core, it was hard to update. Moving it into the compiler_cli allows to release more often until the compiler_cli gets more stable.
Note: Moving the unit test next to the sources is the simplest option for now in terms of build setup.
Note: This commit only does the move. The next commit updates the build to run it again.
This change adds providers for fake router dependecies.
This allows TestComponentBuilder to create components with RouterLink and RouterOutlet directives
without the test writer needing to override them.
BREAKING CHANGE:
- ViewRef.changeDetectorRef was removed as using ChangeDetectorRefs
for EmbeddedViewRefs does not make sense. Use ComponentRef.changeDetectorRef
or inject ChangeDetectorRef instead.
Fixes#8242
The previous code that had `try/catch` statements in methods could not be optimized by Chrome.
This change separates `AppView` (no `try/catch`) form `DebugAppView` (always `try/catch`). Our codegen will use `AppView` in production mode and `DebugAppView` in debug mode.
Closes#8338
BREAKING CHANGE:
- `DynamicComponentLoader` is deprecated. Use `ComponentResolver` and `ViewContainerRef` directly.
- `DebugNode.inject` is deprecated. use `DebugNode.injector.get` instead.
BREAKING CHANGE:
- Before, a `EmbeddedViewRef` used to have methods for
setting variables. Now, a user has to pass in a context
object that represents all variables when an `EmbeddedViewRef`
should be created.
- `ViewContainerRef.createEmbeddedViewRef` now takes
a context object as 2nd argument.
- `EmbeddedViewRef.setLocal` and `getLocal` have been removed.
Use `EmbeddedViewRef.context` to access the context.
- `DebugNode.locals` has been removed. Use the new methods `DebugElement.references`
to get the references that are present on this element,
or `DebugElement.context` to get the context of the `EmbeddedViewRef` or the component to which the element belongs.
Closes#8321
This tool lets us re-write TypeScript sources before entering the emit pipeline.
For example, we lower Decorators to the tree-shakable Annotation form.
These worked in Dart because they were effectively exported even without the export keyword.
Without exporting these symbols, they are not produced in .metadata.json files, which leaves
dangling references from the Decorators that use them.
Instantiating the test component within an NgZone will let us track async tasks in event handlers and change detection.
We can also do auto change detection when triggering events through dispatchEvent and not have to do fixture.detectChange() manually in the test.
New API:
ComponentFixture.autoDetectChanges() - This puts the fixture in auto detect mode that automatically calls detectChanges when the microtask queue is empty (Similar to how change detection is triggered in an actual application).
ComponentFixture.isStable() - This returns a boolean whether the fixture is currently stable or has some async tasks that need to be completed.
ComponentFixture.whenStable() - This returns a promise that is resolved when the fixture is stable after all async tasks are complete.
Closes#8301
The filename contains the module name as resolved by users, so the top-level module name is uneeded.
Module names on references are replaced by capturing the import syntax from the module.
This allows readers of the metadata to do the module resolution themselves.
Fixes#8225Fixes#8082Closes#8256
Remove FunctionWithParamTokens.
All test wrappers async, fakeAsync and inject now return just a Function instead of FunctionWithParamTokens. This makes them directly consumable by the test framework. Also the test framework code does not have to handle a union of Function and FunctionWithParamTokens everywhere.
The Function returned by the above methods are considered asynchronous by the test framework if they return a Promise, synchronous otherwise.
Closes#8257
Introduces `ref-` to give a name to an element or a directive (also works for `<template>` elements), and `let-` to introduce an input variable for a `<template>` element.
BREAKING CHANGE:
- `#...` now always means `ref-`.
- `<template #abc>` now defines a reference to the TemplateRef, instead of an input variable used inside of the template.
- `#...` inside of a *ngIf, … directives is deprecated.
Use `let …` instead.
- `var-...` is deprecated. Replace with `let-...` for `<template>` elements and `ref-` for non `<template>` elements.
Closes#7158Closes#8264

Closes#7397Closes#8217
Pure pipes as well as arrays and maps are
implemented via proxy functions. This is
faster than the previous implementation
and also generates less code.
BREAKING CHANGE:
- pipes now take a variable number of arguments, and not an array that contains all arguments.
Update the version of zone.js to @0.6.12 that contains the new FakeAsyncTestZoneSpec.
The new fakeAsync zone handles errors better and clearPendingTimers() is no longer required to be called after handling an error and is deprecated.
The fakeAsync test zone will now throw an error if an XHR is attemtped within the test since that cannot be controlled synchronously in the test(Need to be mocked out with a service implementation that doesn't involve XHRs).
This commit also allows fakeAsync to wrap inject to make it consistent with async test zone.
BREAKING CHANGE:
inject can no longer wrap fakeAsync while fakeAsync can wrap inject. So the order in existing tests with inject and fakeAsync has to be switched as follows:
Before:
```
inject([...], fakeAsync((...) => {...}))
```
After:
```
fakeAsync(inject([...], (...) => {...}))
```
Closes#8142
This changes Angular so that it can be used without reflection (assuming a codegen for injectors).
BREAKIKNG CHANGE:
- Drops `APP_COMPONENT` provider. Instead, inject
`ApplicationRef` and read its `componentTypes` property.
- long form bootstrap has changed into the following:
```
var platform = createPlatform(ReflectiveInjector.resolveAndCreate(BROWSER_PROVIDERS));
var appInjector =
ReflectiveInjector.resolveAndCreate([BROWSER_APP_PROVIDERS, appProviders], platform.injector);
coreLoadAndBootstrap(appInjector, MyApp);
```
BREAKING CHANGE:
- Injector was renamed into `ReflectiveInjector`,
as `Injector` is only an abstract class with one method on it
- `Injector.getOptional()` was changed into `Injector.get(token, notFoundValue)`
to make implementing injectors simpler
- `ViewContainerRef.createComponent` now takes an `Injector`
instead of `ResolvedProviders`. If a reflective injector
should be used, create one before calling this method.
(e.g. via `ReflectiveInjector.resolveAndCreate(…)`.
This adds the feature for `@ViewChild`/`@ViewChildren`/`@ContentChild`/`@ContentChildren` to define what to read from the queried element.
E.g. `@ViewChild(`someVar`, read: ViewContainerRef)` will locate the element with a variable `someVar` on it and return a `ViewContainerRef` for it.
Background: With this change, Angular knows exactly at which elements there will be `ViewConainerRef`s as the user has to ask explicitly of them. This simplifies codegen and will make converting Angular templates into server side templates simpler as well.
BREAKING CHANGE:
- `DynamicComponentLoader.loadIntoLocation` has been removed. Use `@ViewChild(‘myVar’, read: ViewContainerRef)` to get hold of a `ViewContainerRef` at an element with variable `myVar`.
- `DynamicComponentLoader.loadNextToLocation` now takes a `ViewContainerRef` instead of an `ElementRef`.
- `AppViewManager` is renamed into `ViewUtils` and is a mere private utility service.
Each compile template now exposes a `<CompName>NgFactory` variable
with an instance of a `ComponentFactory`.
Calling `ComponentFactory.create` returns a `ComponentRef` that can
be used directly.
BREAKING CHANGE:
- `Compiler` is renamed to `ComponentResolver`,
`Compiler.compileInHost` has been renamed to `ComponentResolver.resolveComponent`.
- `ComponentRef.dispose` is renamed to `ComponentRef.destroy`
- `ViewContainerRef.createHostView` is renamed to `ViewContainerRef.createComponent`
- `ComponentFixture_` has been removed, the class `ComponentFixture`
can now be created directly as it is no more using private APIs.
closes https://github.com/angular/angular/issues/4943
BREAKING CHANGE:
`Location` and other related providers have been moved out of `router` and into `platform/common`. `BrowserPlatformLocation` is not meant to be used directly however advanced configurations may use it via the following import change.
Before:
```
import {
PlatformLocation,
Location,
LocationStrategy,
HashLocationStrategy,
PathLocationStrategy,
APP_BASE_HREF}
from 'angular2/router';
import {BrowserPlatformLocation} from 'angular2/src/router/location/browser_platform_location';
```
After:
```
import {
PlatformLocation,
Location,
LocationStrategy,
HashLocationStrategy,
PathLocationStrategy,
APP_BASE_HREF}
from 'angular2/platform/common';
import {BrowserPlatformLocation} from 'angular2/src/platform/browser/location/browser_platform_location';
```
Closes#7962
Instead of using injectAsync and returning a promise, use the `async` function
to wrap tests. This will run the test inside a zone which does not complete
the test until all asynchronous tasks have been completed.
`async` may be used with the `inject` function, or separately.
BREAKING CHANGE:
`injectAsync` is now deprecated. Instead, use the `async` function
to wrap any asynchronous tests.
Before:
```
it('should wait for returned promises', injectAsync([FancyService], (service) => {
return service.getAsyncValue().then((value) => { expect(value).toEqual('async value'); });
}));
it('should wait for returned promises', injectAsync([], () => {
return somePromise.then(() => { expect(true).toEqual(true); });
}));
```
After:
```
it('should wait for returned promises', async(inject([FancyService], (service) => {
service.getAsyncValue().then((value) => { expect(value).toEqual('async value'); });
})));
// Note that if there is no injection, we no longer need `inject` OR `injectAsync`.
it('should wait for returned promises', async(() => {
somePromise.then() => { expect(true).toEqual(true); });
}));
```
Closes#7735
BREAKING CHANGE:
- Renderer:
* renderComponent method is removed form `Renderer`, only present on `RootRenderer`
* Renderer.setDebugInfo is removed. Renderer.createElement / createText / createTemplateAnchor
now take the DebugInfo directly.
- Query semantics:
* Queries don't work with dynamically loaded components.
* e.g. for router-outlet: loaded components can't be queries via @ViewQuery,
but router-outlet emits an event `activate` now that emits the activated component
- Exception classes and the context inside changed (renamed fields)
- DebugElement.attributes is an Object and not a Map in JS any more
- ChangeDetectorGenConfig was renamed into CompilerConfig
- AppViewManager.createEmbeddedViewInContainer / AppViewManager.createHostViewInContainer
are removed, use the methods in ViewContainerRef instead
- Change detection order changed:
* 1. dirty check component inputs
* 2. dirty check content children
* 3. update render nodes

TL;DR: Modify pubspec.yaml files to use the recommended "targeted"
transformers. The unified "simple" angular2 transformer still works as
always, but we want to encourage use of the targeted transformers
whereever possible.
See [the wiki](https://github.com/angular/angular/wiki/Advanced-Transformer-Configuration)
for details about targeted transformers.
See #1872
Until Angular 1.5.1 is released, the `$routeConfig` and `$routerCanActivate`
annotations for components must live on the controller constructor.
In Angular 1.5.1, it will automatically copy these annotations across from
the component definition file.
Closes#7319
These tests were registering new components after the application had
been bootstrapped, which is not a valid use case for synchronous routes
in Angular 1.
In particular it was registering the "root" component, which caused the
`$rootRouter` to blow up, when it was instantiated, pointing to a root
component that did not yet exist.
The directiveIntrospector was a bit of a hack to allow the router to
read the `$routeConfig` annocation and `$routerCanActivate` hook from
directives when they were registered.
It turns out that if we put these properties on the component controller's
constructor function (i.e. as static class methods) then we can simply
use the `$injector` to access it as required.
Currently, people put the properties directly on their component definition
objects. In Angular 1.5.1, we will copy these properties onto the controller
constructor to maintain a simple migration path. But going forward it may be
better to encourage people to add the properties directly to the controller
constructor.

process.env.TRAVIS_PULL_REQUEST contains a string and not a boolean value, so we need
to compare it to a string literal rather than do boolean arithmetics.
Create transformers that allow specifying transformer actions on
specific libraries.
* angular2/transform/codegen: Generates all necessary code.
* angular2/transform/reflection_rewriter: Replaces `bootstrap` calls in
application entry points to remove transitive dart:mirrors import,
resulting in smaller code size & faster execution.
* angular2/transform/deferred_rewriter: Rewrites deferred imports and
`loadLibrary` calls to initialize Angular2 and preserve deferred
operation.
Proper configuration of these three transformers can replace the single
angular2 transformer, resulting in significant performance gains for
builds of large angular2 apps.
Update angular2 itself to declare the codegen transformer, since it has
neither deferred imports nor application entry points.
Remove the undocumented & unused quick_transformer.
Instead of running with karma and the karma-dart shim, run dart
tests directly using the new package:test runner. This migrates

been created.
Remove karma-dart and associated files. Change gupfiles to run tests
via `pub run test` instead.
Add a check in `ReflectionCapabilities#interfaces` which determines if
the passed-in type implements a Lifecycle Interface but does not declare
that it does so.

`OnPushObserve` was an experimental

conceptual performance problems,
as setting up observables is slow.
Use `OnPush` instead.
Our transformer unit tests currently use package:guinness, which uses
package:unittest under the covers. package:unittest has been updated and
renamed package:test, so for simplicity migrate test to use package:test

This breakage does not materially affect the size of the generated code,

The singleton service that represents the top level router was called
`$router` but this is confusing since there are actually lots of routers,
which depend upon where you are in the DOM. This is similar to the situation
with scopes.

Despite local testing, multiple users failed to run the postinstall to install typings.
Instead, we can distribute the typings we installed locally.
This is an alternative to #7003.
This also reverts rxjs to beta.1 since we have errors using beta.2, being addressed
in #7001.
Fixes#7000
Currently, validators extending built-in validators are treated as built-in.
This can result in an error when both a real built-in validator and a custom one are applied to the same element.
Closes#6981
Url path of star segments should equal the original path.
If you register the route `/app/*location` and invoke a url like `/app/foo/bar`
the PathRecognizer should return a url path equal to the invoked url.
Before this patch, everything after `foo` was ignored, which resulted in a
redirect to `/app/foo` which was probably not intended (at least in the angular
1.5 component router).
Closes#6976
In angular2 `Location.path()` returns the complete path including query string. In angular1 the query parameters are missing. Similar to this `Location.go` does accept two parameters (path *and query*).
Closes#6943
In Angular 1.5 there is a new helper method for creating component directives.
See https://docs.angularjs.org/guide/component for more information about components.
These kind of directives only match the `E` element form and the previously component
router only created HTML that matched directives that matched the `A` attribute form.
This commit changes the `<ng-outlet>` directive so that it generates custom HTML
elements rather divs with custom attributes to trigger the relevant component to
appear in the DOM.
Going forward, Angular 1.5 users are encouraged to create their router components
using the following style:
```
myModule.componnet('component-name', {
// component definition object
});
```
Closes angular/angular.js#13860
Closes#6076Closes#5278
BREAKING CHANGE:
The component router now creates custom element HTML rather than custom attribute
HTML, in order to create a new component. So rather than
```html
<div custom-component></div>
```
it now creates
```html
<custom-component></custom-component>
```
If you defined you router components using the `directive()` helper and
specified the `restrict` properties such that element matching was not allowed,
e.g. `restrict: 'A'` then these components will no longer be instantiated
by the component router and the outlet will be empty.
The fix is to include `E` in the `restrict` property.
`restrict: 'EA'`
Note that this does not affect directives that did not specify the `restrict`
property as the default for this property is already `EA`.
This resolves Duplicate Identifier issues seen by many users,
at the expense of more typings installation required in some
cases.

We previously had an undocumented breaking change, this is now
documented in this commit.
Fixes#6817
BREAKING CHANGE:
Transitive typings are no longer included in the distribution.
You may need to install typings in your project using
http://github.com/typings/typings
Users now must rely on getting typings from:
- one of the peerDependencies, such as rxjs, which exposes
typings via the moduleResolution=node mechanism.
(see https://github.com/Microsoft/TypeScript/wiki/Typings-for-npm-packages)
This happens automatically.
- Using --target ES5 now requires manual installation of
es6-promise and es6-collections typings.
- Using some angular APIs may introduce a dependency on eg. nodejs
or jasmine, and those typings need manual installation as well.
Closes#6267
The upstream Jasmine typings don't define a type for the global
object with Jasmine methods polluting it, so just use any.
Also zone.js has a different name upstream.

Issue raised in PR #6745.

`throw` in this case instead, so we know early that something has likely
gone wrong.

- Importing bootstrap.dart deferred

Closes#6749
Previously, we generated the code to initialize the reflector into the
<file>.ng_deps.dart and the compiled template and change detector code
into <file>.template.dart.
Update the transformer to generate all code into <file>.template.dart to
avoid the additional HTTP requests necessary when debugging
applications in Dartium.
Now, using `ng.probe(element)` in the browser console returns
a DebugElement when in dev mode.
`ComponentFixture#debugElement` also returns a new DebugElement.
Breaking Change:
This is a breaking change for unit tests. The API for the DebugElement
has changed. Now, there is a DebugElement or DebugNode for every node
in the DOM, not only nodes with an ElementRef. `componentViewChildren` is
removed, and `childNodes` is a list of ElementNodes corresponding to every
child in the DOM. `query` no longer takes a scope parameter, since
the entire rendered DOM is included in the `childNodes`.
Before:
```
componentFixture.debugElement.componentViewChildren[0];
```
After
```
// Depending on the DOM structure of your component, the
// index may have changed or the first component child
// may be a sub-child.
componentFixture.debugElement.children[0];
```
Before:
```
debugElement.query(By.css('div'), Scope.all());
```
After:
```
debugElement.query(By.css('div'));
```
Before:
```
componentFixture.debugElement.elementRef;
```
After:
```
componentFixture.elementRef;
```
BEFORE:
The following would throw in the dev mode because `f` would return a new array when called by checkNoChanges.
@Component({
template: `
{{f()}}
`
})
class A {
f() { return [1]; }
}
AFTER:
The checkNoChanges function compares only primitives types for equality, and deeply compares iterables. Other objects cannot cause checkNoChanges to throw. This means that the dev mode would never fail given a legal program, but may allow some illegal programs.
Also enable DDC checks across all non-web worker playground apps. We are
now down to 2 DDC errors across all of them. The remaining two need to be
fixed in package:analyzer, not in angular.

signature changed.
Closes#6693
This is needed to prevent memory leaks. The DOM

Widen version dependencies for `package:angular`, `package:code_transformers`,

`package:guinness` uses `package:unittest` while

This causes our end-to-end Dart transformer tests (which use testing
code in `package:code_transformers`) to be skipped.

- Move e2e tests to run in a separate file
- Run `gulp test.server.dart` tests serially

2. analyzes generated code, which does run in the browser and which we failed to analyze in the previous version of the build
Closes#6436
With providers split into bundles, the test injector is now able to
use providers for a given bundle. Suggested provider lists for tests are
available in `angular2/platform/testing/<platform>`.
Change the providers for a test suite using `setBaseTestProviders`. This
should be done once at the start of the test suite, before any test cases
run.
BREAKING CHANGE: Tests are now required to use `setBaseTestProviders`
to set up. Assuming your tests are run on a browser, setup would change
as follows.
Before:
```js
// Somewhere in test setup
import {BrowserDomAdapter} from 'angular2/src/platform/browser/browser_adapter';
BrowserDomAdapter.makeCurrent
```
After:
```js
// Somewhere in the test setup
import {setBaseTestProviders} from 'angular2/testing';
import {

BREAKING CHANGE:
- Platform pipes can only contain types and arrays of types,
but no bindings any more.
- When using transformers, platform pipes need to be specified explicitly
in the pubspec.yaml via the new config option
`platform_pipes`.
- `Compiler.compileInHost` now returns a `HostViewFactoryRef`
- Component view is not yet created when component constructor is called.
-> use `onInit` lifecycle callback to access the view of a component
- `ViewRef#setLocal` has been moved to new type `EmbeddedViewRef`
- `internalView` is gone, use `EmbeddedViewRef.rootNodes` to access
the root nodes of an embedded view
- `renderer.setElementProperty`, `..setElementStyle`, `..setElementAttribute` now
take a native element instead of an ElementRef
- `Renderer` interface now operates on plain native nodes,
instead of `RenderElementRef`s or `RenderViewRef`s
Closes#5993
Previously when comparing which of multiple possible routes to choose in
an ambiguous case, we looked at the specificity of the target of redirect
matches rather than the original match. This meant that if a redirect
used a whilecard, but redirected to a target that was a static path,
we'd cound the static path's specificity instead of the wildcard.
This change stores the specificity of the redirect on the RedirectInstruction.
Closes#5933
This changes the way we calculate specificity. Instead of using a number,
we use a string, so that combining specificity across parent-child instructions
becomes a matter of concatenating them

BREAKING CHANGE:
- This is very unlikely to be breaking, but I'm still marking just in case. The only change to the user should be that dev mode is driven by Dart's checked mode, like it was in the past.
BREAKING CHANGE
Before
Previously Angular would run in dev prod mode by default, and you could enable the dev mode by calling enableDevMode.
After
Now, Angular runs in the dev mode by default, and you can enable the prod mode by calling enableProdMode.
Before #5375, injectAsync would check the return value and fail
if it was not a promise, to help users remember that they need to
return a promise from an async test. #5375 removed that with the
introduction of the testing zone.
This un-deprecates `injectAsync` until we can resolve
https://github.com/angular/angular/issues/5515.
To be clear, this means that `inject` and `injectAsync` are now
identical except that `injectAsync` will fail if the test
does not return a promise, and `inject` will fail if the test
returns any value.

Note: This only applies to JavaScript, Dart is not changed.

BREAKING CHANGE:
The following symbols are not exported from angular2/angular2 any more:
`UrlResolver`, `AppRootUrl`, `getUrlScheme`, `DEFAULT_PACKAGE_URL_PROVIDER`.
Use imports from `angular2/compiler` instead.
This changes the public api spec to check each public barrel individually
to make sure its API has not changed. The previous API spec has been
preserved but split into respective barrels.
The compiler barrel has been added to the spec, along with all of its
public exports. Previously, angular2/angular2 was only exporting a
handful of symbols from compiler, so there are now many more symbols
being tested in the spec for compiler than previously.

BREAKING CHANGE:
toPromise is no longer an instance method of the `Observable` returned
by Angular, and fromPromise is no longer available as a static method.
The easiest way to account for this change in applications is to import
the auto-patching modules from rxjs, which will automatically add these
operators back to the Observable prototype.
```
import 'rxjs/add/operator/toPromise';

A new verion is causing build issues, perhaps due to an undeclared
dependency on package:test. For now, lock down the version to the
last known working one.
Currently, importing from 'angular2/angular2', in addition to providing Angular tokens, brings in global-es6.d.ts. Since we are deprecating 'angular2/angular2', we need to do the same in 'angular2/core'.
BREAKING CHANGE:
`<whatever />` used to be expanded to `<whatever></whatever>`.
The parser now follows the HTML5 spec more closely.
Only void and foreign elements can be self closed.
Closes#5591
BREAKING CHANGE
End tags used to be tolerated for void elements with no content.
They are no more allowed so that we more closely follow the HTML5 spec.

BREAKING CHANGE:
You can no longer bootstrap a WebWorker or Isolate using `bootstrap` or `bootstrapWebWorker`. Instead you have to do the following:
In TypeScript:
```TypeScript
// index.js
import {WORKER_RENDER_PLATFORM, WORKER_RENDER_APPLICATION, WORKER_SCRIPT} from "angular2/platforms/worker_render";
import {platform} from "angular2/platform";
platform([WORKER_RENDER_PLATFORM])
.application([WORKER_RENDER_APPLICATION, new Provider(WORKER_SCRIPT, {useValue: "loader.js"});
```
```JavaScript
// loader.js
importScripts("https://cdnjs.cloudflare.com/ajax/libs/es6-shim/0.33.3/es6-shim.js", "https://jspm.io/system@0.16.js", "angular2/web_worker/worker.js");
System.import("app");
```
```TypeScript
// app.ts
import {Component, View} from "angular2/core";
import {WORKER_APP_PLATFORM, setupWebWorker} from "angular2/platforms/worker_app";
import {platform} from "angular2/platform";
@Component({
selector: "hello-world"
})
@View({
template: "<h1>Hello {{name}}</h1>
})
export class HelloWorld {
name: string = "Jane";
}
platform([WORKER_APP_PLATFORM])
.asyncApplication(setupWebWorker, optionalProviders?)
.then((ref) => ref.bootstrap(RootComponent));
```
In Dart:
```Dart
// index.dart
import "angular2/platform.dart";
import "angular2/platforms/worker_render.dart";
main() {
platform([WORKER_RENDER_PLATFORM])
.asyncApplication(initIsolate("my_worker.dart"));
}
```
```Dart
// background_index.dart
import "angular2/platform.dart";
import "angular2/platforms/worker_app.dart";
import "package:angular2/src/core/reflection/reflection.dart";
import "package:angular2/src/core/reflection/reflection_capabilities.dart";
@Component(
selector: "hello-world"
)
@View(
template: "<h1>Hello {{name}}</h1>"
)
class HelloWorld {
String name = "Jane";
}
main(List<String> args, SendPort replyTo) {
reflector.reflectionCapabilities = new ReflectionCapabilities();
platform([WORKER_APP_PLATFORM])
.asyncApplication(setupIsolate(replyTo))
.then((ref) => ref.bootstrap(RootComponent));
}
```
You should no longer import from the `angular2/web_worker/worker` and `angular2/web_worker/ui` paths. Instead you can now import directly from core, directives, etc..
The WebWorkerApplication class has been removed. If you want to use ServiceMessageBroker or ClientMessageBroker on the render thread, you must inject their factories via DI.
If you need to use the MessageBus on the render thread you must also obtain it through DI.

Closes#5230
The typings property is being removed because angular2.ts is deprecated, and the developers should import from angular2/core and angular2/platform/*. So aliasing angular2 to angular2/angular2 does not make sense.
BREAKING CHANGE
Before
import * as ng from 'angular2';
After
import * as core from 'angular2/core';
I think people new to promises, angular etc will find this example easier to understand with concrete identifiers from a simple use-case. The existing naming could be confused with promise/angular functionality (`promise` in the template, `resolved` etc).
Also I made `resolve` private, as then it's clear what we're exposing for the template.
BREAKING CHANGE:
Previously, pipes that wanted to be notified when they were destroyed
would implement the PipeOnDestroy interface and name the callback
`onDestroy`. This change removes the PipeOnDestroy interface and
instead uses Angular's lifecycle interface `OnDestroy`, with the
`ngOnDestroy` method.
Before:
```
import {Pipe, PipeOnDestroy} from 'angular2/angular2';
@Pipe({pure: false})
export class MyPipe implements PipeOnDestroy {
onDestroy() {}
}
```
After:
import {Pipe, OnDestroy} from 'angular2/angular2';
@Pipe({pure: false})
export class MyPipe implements PipeOnDestroy {
ngOnDestroy() {}
}
BREAKING CHANGE:
Previously, components that would implement lifecycle interfaces would include methods
like "onChanges" or "afterViewInit." Given that components were at risk of using such
names without realizing that Angular would call the methods at different points of
the component lifecycle. This change adds an "ng" prefix to all lifecycle hook methods,
far reducing the risk of an accidental name collision.
To fix, just rename these methods:
* onInit
* onDestroy
* doCheck
* onChanges
* afterContentInit
* afterContentChecked
* afterViewInit
* afterViewChecked
* _Router Hooks_
* onActivate
* onReuse
* onDeactivate
* canReuse
* canDeactivate
To:
* ngOnInit,
* ngOnDestroy,
* ngDoCheck,
* ngOnChanges,
* ngAfterContentInit,
* ngAfterContentChecked,
* ngAfterViewInit,
* ngAfterViewChecked
* _Router Hooks_
* routerOnActivate
* routerOnReuse
* routerOnDeactivate
* routerCanReuse
* routerCanDeactivate
The names of lifecycle interfaces and enums have not changed, though interfaces
have been updated to reflect the new method names.

This is a big change. @matsko also deserves much of the credit for the implementation.
Previously, `ComponentInstruction`s held all the state for async components.
Now, we introduce several subclasses for `Instruction` to describe each type of navigation.
BREAKING CHANGE:
Redirects now use the Link DSL syntax. Before:
```
@RouteConfig([
{ path: '/foo', redirectTo: '/bar' },
{ path: '/bar', component: BarCmp }
])
```
After:
```
@RouteConfig([
{ path: '/foo', redirectTo: ['Bar'] },
{ path: '/bar', component: BarCmp, name: 'Bar' }
])
```
BREAKING CHANGE:
This also introduces `useAsDefault` in the RouteConfig, which makes cases like lazy-loading
and encapsulating large routes with sub-routes easier.
Previously, you could use `redirectTo` like this to expand a URL like `/tab` to `/tab/posts`:
@RouteConfig([
{ path: '/tab', redirectTo: '/tab/users' }
{ path: '/tab', component: TabsCmp, name: 'Tab' }
])
AppCmp { ... }
Now the recommended way to handle this is case is to use `useAsDefault` like so:
```
@RouteConfig([
{ path: '/tab', component: TabsCmp, name: 'Tab' }
])
AppCmp { ... }
@RouteConfig([
{ path: '/posts', component: PostsCmp, useAsDefault: true, name: 'Posts' },
{ path: '/users', component: UsersCmp, name: 'Users' }
])
TabsCmp { ... }
```
In the above example, you can write just `['/Tab']` and the route `Users` is automatically selected as a child route.

A quoted expression is:
quoted expression = prefix `:` uninterpretedExpression
prefix = identifier
uninterpretedExpression = arbitrary string
Example: "route:/some/route"
Quoted expressions are parsed into a new AST node type Quote. The `prefix` part of the
node must be a legal identifier. The `uninterpretedExpression` part of the node is an
arbitrary string that Angular does not interpret.
This feature is meant to be used together with template AST transformers introduced in
a43ed79ee7. The
transformer would interpret the quoted expression and convert it into a standard AST no
longer containing quoted expressions. Angular will continue compiling the resulting AST
normally.

Often some init logic needs to run when a platform or an application is boostrapped.
For example, boostraping a platform requires initializing the dom adapter.
Now, it can be done as follows:
new Provider(PLATFORM_INITIALIZER, {useValue: initDomAdapter, multi: true}),
All platform initializers will be run after the platform injector has been created.
Similarly, all application initializers will be run after the app injector has been
created.
Closes#5355
Currently, core depends on DomRenderer, which depends on the browser.
This means that if you depend on angular2/core, you will always
pull in the browser dom adapter and the browser render, regardless
if you need them or not.
This PR moves the browser dom adapter and the browser renderer out of core.
BREAKING CHANGE
If you import browser adapter or dom renderer directly (not via angular2/core),
you will have to change the import path.
Since editors and IDEs do typechecking and show errors in place,
often there is no benefit to running type checking in our test pipeline.

Previously, the controlsErrors getter of ControlGroup and ControlArray returned the errors of their direct children. This was confusing because the result did not include the errors of nested children (ControlGroup -> ControlGroup -> Control). Making controlsErrors to include such errors would require inventing some custom serialization format, which applications would have to understand.
Since controlsErrors was just a convenience method, and it was causing confusing, we are removing it. If you want to get the errors of the whole form serialized into a single object, you can manually traverse the form and accumulate the errors. This way you have more control over how the errors are serialized.

In the previous commit I removed unused dependencies from package.json, but in order for the change to take
effect I needed to update npm shrinkwrap as well. That got complicated because of how npm dedupes packages.
Long story short, to clean up the mess I did the following:
- deleted npm-shrinkwrap.json and npm-shrinkwrap.clean.json
- ran: npm install
- ran: npm shrinkwrap --dev && ./tools/npm/clean-npm-shrinkwrap
This means that our npm-shrinkwrap now correctly reflects the constraints in package.json, but it also
means that some packages got updated (within the version constrain specified in package.json).
Some dependencies were intentionally not updated. e.g. mudge due to #5022
otherwise in dist/js/dev/es5/benchmarks/src/naive_infinite_scroll/index.html
defaultExtension: 'js' is ignored for angular2/src/testing/benchmark_util which
results in test failures.
We'll need to investigate this. Maybe upgrading to 0.19.x will make this issue go
away...
Store dependency import information in a dedicated list in `NgDepsModel`
rather than as a boolean field on `ImportModel`. An `ImportModel` should
not "care" whether it is a .ng_deps.dart import or not -- this
information belongs in `NgDepsModel`.
This simplifies some of the logic around how `NgDepsModel` imports are
processed and eventually output.
Third party controls require a ControlValueAccessor to function with Angular Forms. Many of them, like Polymer's <paper-input>, behave like the <input> native element and thus can use the DefaultValueAccessor. Adding an ng-default-control attribute will now allow them to use that directive.
Closes#5076
- Move zone-related code out of logger.dart and into zone.dart.
- Rename `logger` => `log`.

If the anchor element on which the "router-link" directive is present has a target
attribute other than "_self," the handler will not prevent default behavior of
the browser.

Ambient directives can be configured when bootstraping an application.
Ambient directives can be used in every component of the application without
needing to explicitly list them.
Previously, routes would be generated with a leading slash after the parens:
example.com/foo(/bar)
This fix removes the trailing slash when generating the URL, so now we have:
example.com/foo(bar)
This change is not breaking because we still recognize both forms. We just normalize
without the slash.
Previously if the URL changed in `HashLocation` mode, the router would not pick up the change.
This adds a listener in `HashLocationStrategy` for `hashchange` events to fix the problem.
Closes#5013
For exported, generated templates, declare with `final` so `dart2js`

Refactor EventEmitter and Async Facade to match ES7 Observable semantics, properly use RxJS typedefs, make EventEmitter inherit from RxJS Subject. Closes#4149.
BREAKING CHANGE:
- consumers of EventEmitter no longer need to call .toRx()
- EventEmitter is now generic and requires a type - e.g. `EventEmitter<string>`
- EventEmitter and Observable now use the `.subscribe(generatorOrNext, error, complete)` method instead of `.observer(generator)`
- ObservableWrapper uses `callNext/callError/callComplete` instead of `callNext/callThrow/callReturn`
We used to use different external css parsers,
depending on the `DomAdapter`. This lead to
inconsistent behavior and environment specific errors.

Currently, the only way for a directive to export a validator is by providing a function. This makes it ackward to write validators that depend on directive inputs. In addition to supporting functions as validators, classes implementing the Validator interface are supported too.
The current code doesn't function properly:

Previously, importing a library twice using different prefixes could
cause the template compiler step to incorrect omit `Directive`
dependencies provided by that library.
Previously, we parsed dependencies out of a the stringified value of
`directives`, which is brittle and error-prone.
Move this parsing into `DirectiveProcessor` where we have the full Dart
ast to help.
Previously, `DeferredRewriter` checked for the existence of
`.ng_deps.dart` files to determine which deferred libraries it needed to
rewrite, requiring that those assets exist at the time it was run.
Update to check for `.ng_meta.json` files instead, which exist after the
`DirectiveProcessor` phase. This allows the `DeferredRewriter` (which
only processes *.dart files) to run in
parallel with `TemplateComplier` (which only processes *.ng_meta.json
files) and `StylesheetCompiler` (which only processes *.css files).
Have DeferredRewriter to check existence of .ng_meta.json assets rather than .ng_deps.dart assets
Update `DirectiveProcessor` and `TemplateCompiler` to generate the
getters, setters, and methods currently generated in `BindGenerator`.
Update `DirectiveMetadataLinker` to output `.ng_meta.json` files instead
of `.ng_deps.dart` files, avoiding full codegen until the last phase.
This allows us to dedupe codegen logic and remove an additional phase
from the transformer.
- fixes wrapping for object literal keys called `template`.
- spacing in destructuring expressions.
- changes to keep trailing return types of functions closer to their
function declaration.
- better formatting of string literals.

This was used for , but now that our typings are laid out in the node_module, users should no longer need that.
Also fix the project name in root package.json. There is a risk that someone runs npm publish in this directory, which will create a new version of angular 1, and contain a scary source tree.
So this package.json may as well have a name that doesn't exist on npm, and if we did publish by accident, it would be a package name that matches the contents.
The test injector now uses an XHR implementation based on DOM.getXHR,
which allows the current DOM adapter to dictate which XHR impl should
be used.
To prevent the changes to DOM adapter from introducing undesired new
dependencies into the benchmarks, separate the async facade into
a promise facade which is reexported by facade/async.

reference absolute urls with e.g. `http://`. This
behavior was already present for `@import` rules
within stylesheets.
Closes#4740
Now that we can specify `directives` in either `@View` or `@Component`,
we will try to parse from both.
Previously, we would trash any `directives` parsed in the first
annotation upon encountering the second annotation. This ensures that we
maintain that list of `directives` regardless of annotation ordering.
Handle the situation where a `.dart` file generates a `.ng_meta.json`
file but does not register any reflective information.
An example of this would be a file that defines a const list that looks
like a directive alias. The transformer keeps track of this, and creates
a `.ng_meta.json` file but never creates a `.ng_deps.dart` file, which
can result in other files being linked to it and it not defining an
`initReflector` method.
This splits out `path` and `query` into separate params for `location.go`
and related methods so that we can handle them properly in both `PathLocationStrategy`
and `HashLocationStrategy`.
This handles the problem of not reading query params to populate `Location` on the
initial page load.

Adds test adapters for TypeScript and JavaScript only, exported
as part of the test_lib module. These work with the Jasmine test
framework, and allow use of the test injector within test blocks
via the `inject` function.
See #4572, #4177, #4035, #2783
This includes the TestComponentBuilder. It allows using the
test injector with Jasmine bindings, and waits for returned
promises before completing async test blocks.
This is useful for the compiler tests, but otherwise it's not useful.
Additionally if an application has external templates (as is common) then
we should actually fetch these templates in tests.
Fixes#4539Closes#4682
This is pretty experimental, but the goal is to track the performance
of our build over time so that we can more easily track perf regressions.
Currently it's integrated only with gulp tasks, but I'd like to expand it
to tracking travis jobs, protractor/benchpress test runs, npm installs, etc.
No PII is being collected. And the data is collected via a Google Analytics
property owned by the Angular team account.

Closes#4638
`DeferredRewriter` depends on the presence of `.ng_deps.dart` files,
which do not yet exist in the phase where it was previously run.
Update the transformer phases to fix this and add an integration test to
prevent regression.
Link `NgDeps` & `NgMeta` data in the same phase to avoid unnecessary asset
creation & reading.
Remove `NgMeta#exports` and instead use `NgDeps#exports` to link `NgMeta` files
in `ng_meta_linker.dart`.
The `ms` & `moz` prefixes are not needed. `ms` was never available in a public
IE release (IE 10 has an unprefixed version) and Firefox has unprefixed
rAF since v24 - current version is 41. Even more, Firefox versions below 22
don't have cancelAnimationFrame so it's better to not use the prefixed version
at all to avoid surprises.
The `o` prefix is also useless - Opera Presto never had rAF and the
Chromium-based Opera doesn't use the `o` prefix.
Also, switched from `new Date().getTime()` to `Date.now()` as it's supported
everywhere (even in Android 2.3) except IE<9 and it avoids a useless date
object construction.

mock-fs is currently incompatible with node 4.x, but a fix is in progress
https://github.com/tschaub/mock-fs/issues/59
Since we are currently not actively developing the affected broccoli plugins,
the risk of disabling these tests is low, especially in the light of
improvements we get from node 4.x.
These dependencies required upgrade in order for us to run on Node v4.x

This was a poorly typed attempt to mimic TypeScript's index signatures,
which we can use instead.
This eliminates a very strange type that we were exposing to users, but
not re-exporting through our public API.

Previously, annotations which were const objects (as opposed to const
instance creation expressions) were incorrectly output as instance
creation expressions.

```
Closes#4481
BREAKING CHANGE:
- Removes `ChangeDetection`, use a binding for `ChangeDetectorGenConfig` instead
to configure change detection.
- `RenderElementRef.renderBoundElementIndex` was renamed to `RenderElementRef.boundElementIndex`.
- Removes `ViewLoader`, use `XHRImpl` instead.
Closes#3605
BREAKING CHANGE:
- we don't mark an element as bound any more if it only contains text bindings
E.g. <div>{{hello}}</div>
This changes the indices when using `DebugElement.componentViewChildren` / `DebugElement.children`.
- `@Directive.compileChildren` was removed,
`ng-non-bindable` is now builtin and not a directive any more
- angular no more adds the `ng-binding` class to elements with bindings
- directives are now ordered as they are listed in the View.directives regarding change detection.
Previously they had an undefined order.
- the `Renderer` interface has new methods `createProtoView` and `registerComponentTemplate`. See `DomRenderer` for default implementations.
- reprojection with `ng-content` is now all or nothing per `ng-content` element
- angular2 transformer can't be used in tests that modify directive metadata.
Use `angular2/src/transform/inliner_for_test` transformer instead.
The output of the compiler has to be the same
given the same input. Requiring a unique id for
every type already during compilation makes it
hard to parallelize compilation.
Part of #3605Closes#4397
Ensure that the transformers are properly declaring all consumed
outputs. In particular, when a transformer overwrites an output, make
sure the transformer calls `consumePrimary` followed by `addOutput` for
that file.
Prevent `DirectiveLinker` from consuming `.ng_deps.json` files. When we
do this, barback incorrectly calculates the available assets for that
phase, resulting in broken builds.
BREAKING CHANGE: Http now returns Rx Observables directly, so calling .toRx() is no longer necessary. Additionally, Http calls are now cold, so backend requests will not fire unless .subscribe() is called.

Types were previously not handled correctly by the type definition
generation process, so a couple of things in http had to be changed
to interfaces. This issue has been fixed, so now they're types again.
Closes#4024
BREAKING CHANGE:
It's unlikely that any apps were explicitly referencing `RootRouter`, but if they were they should
prefer to use the `routerBindings` helper or the `ROUTER_BINDINGS` const exported from `angular2/router`
- Rename `DirectiveMetadata` into `CompileDirectiveMetadata`, merge
with `NormalizedDirectiveMetadata` and remove `ChangeDetectionMetadata`
- Store change detector factories not as array but
directly at the `CompiledTemplate` or the embedded template
to make instantiation easier later on
- Already analyze variable values and map them
to `Directive.exportAs`
- Keep the directive sort order as specified in the
`@View()` annotation
- Allow to clear the runtime cache in `StyleCompiler`
and `TemplateCompiler`
- Ignore `script` elements to match the semantics of the
current compiler
- Make all components dynamically loadable and remove
the previously introduced property `@Component#dynamicLoadable`
for now until we find a better option to configure this
- Don’t allow to specify bindings in `@View#directives` and `@View#pipes` as this was never supported by the transformer (see below for the breaking change)
BREAKING CHANGE:
- don't support DI bindings in `@View#directives` and `@View@pipes` any more in preparation of integrating the new compiler. Use `@Directive#bindings` to reexport directives under a different token instead.

BREAKING CHANGE:
Previously, route configuration took a controller constructor function as the value of
`component` in a route definition:
```
$route.config([
{ route: '/', component: MyController }
])
```
Based on the name of the controller, we used to use a componentMapper service to
determine what template to pair with each controller, how to bind the instance to
the $scope.
To make the 1.x router more semantically alligned with Angular 2, we now route to a directive.
Thus a route configuration takes a normalized directive name:
```
$route.config([
{ route: '/', component: 'myDirective' }
])
```
BREAKING CHANGE:
In order to avoid name collisions, lifecycle hooks are now prefixed with `$`. Before:
```
MyController.prototype.onActivate = ...
```
After:
```
MyController.prototype.$onActivate = ...
```
Same for `$canActivate` (which now lives on the directive factory function),
`$canDeactivate`, `$canReuse`, and `$onDeactivate` hooks.
Some of our class/interface members are "package private". Typescript doesn't have this concept, so we need to hide them
via the @private doc annotation.
Closes#4262Closes#4264
The debug tools used to take ApplicationRefs, which are the old return
type of bootstrap. Now bootstrap returns ComponentRef, so the debug
tools should be updated.
Closes#4203
To simplify processing and testing in the future, use protobufs to
represent of `.ng_deps.dart` files rather than always dealing
directly in Dart code.
This update does not actually use the protobuf representation, but this
is a step towards moving all phases to parse and use protobufs rather than
Dart code.
This change adds a syntax for bootstrapping Angular on a page that allows more fine-grained control of the hierarchy created. platform() creates a platform injector (of which there can only be one). From the platform, .application() creates an Angular application including a Zone and all specified application bindings (e.g. for the DOM, HTTP, Compiler, Renderer, etc). At the application level, .bootstrap() will bootstrap the given component into that application.
Closes#3852
With the coming bootstrapping changes, a single application (and thus Router) can have multiple root components. One of these needs to be identified as the "primary" component from which the Router will load its configuration. This is now done by providing a ROUTER_PRIMARY_COMPONENT binding to the primary component type.
Previosly, recognition ended when a parent captured all the parsed URL segments.
This caused routes that delegated from a parent to a child with an empty segment
to never be recognized.
Closes#4178
Previously, `router.navigate` took a string representing the URL.
Now, it accepts an array that mirrors the link DSL.
Closes#4040
BREAKING CHANGE
The old method has been renamed to `router.navigateByUrl`.
Either change your navigation calls to use the DSL (preferred) or
call `router.navigateByUrl` instead.
Closes#4074
Previously, async routes generated from links would not load the configs of
their resolved components, which led to broken links in the children of the

Http sfx bundle was not regenerated when bundles.js task was called.
The new bundles are a bit bigger (angular2.min.js 519604 -> 590056 bytes).
Part of it is because TS inlines class shims vs defering to
TraceurRuntime.
BREAKING CHANGE:
TraceurRuntime is no longer need when consuming the angular 2 bundles.
Shims or native support for ES6 Map, Set and Symbol are still needed (can be
provided by es6-shim.js or core.js).

This change moves many APIs to the angular2/core export.
This change also automatically adds FORM_BINDINGS in

Instead of working with finer grained element injectors, queries now
iterate through the views as static units of modification of the
application structure. Views already contain element injectors in the
correct depth-first preorder.
This allows us to remove children linked lists on element injectors and a
lot of book keeping that is already present at the view level.
Queries are recalculated using the afterContentChecked and
afterViewChecked hooks, only during init and after a view container has
changed.
BREAKING CHANGE:
ViewQuery no longer supports the descendants flag. It queries the whole
component view by default.
Closes#3973
Previously the type remap was not being applied to comments and free floating functions.
The nunjucks template was becoming unreadable so rather than making a tweak there I
rewrote it into imperative code that is much easier to follow.
The output was diffed against the old output. The diff contained only the expected changes.
BREAKING CHANGE
Previously a content binding of a component was visible to the directives in its view with the host constraint. This is not the case any more. To access that binding, remove the constraint.
When running in Dartium without using transformers (i.e. with a normal
static web server), handle relative template URLs. This works by using
mirrors to get the URL of the library where the component class is
defined.

Ensure that values passed to `DomRenderer#setElementAttribute` are
strings. Currently, booleans can be passed to this method, resulting in
failures when running in Dart checked mode.
The ENUM_INDEX utility was added to return the index of an enum
consistently between Dart and TypeScript, so that the index
could be used to look up the name of the enum. Since dart is no
longer supported by Http, and since no other part of the framework
is using this function, it has been removed.
Closes#3843
This class was only added to do a reverse lookup of
RequestMethods enum to get its name (i.e. "GET") for Dart.
Since Dart is no longer supported by Http, method names
can just be retrieved with TypeScript's support for
enum name lookup,
i.e. RequestMethods[RequestMethods.GET] === 'GET',
making the RequestMethodsMap utility obsolete.
Closes#2904
BREAKING CHANGE:
This change moves the http module into angular2/, so its import
path is now angular2/http instead of http/http.
Many other modules have also been moved around inside of angular2,
but the public API paths have not changed as of this commit.
Allow a developer to specify a package prefix where the 'package:' dart urls

Currently the transformer generates all getters and setters even when
creating pre-generated change detectors, which remove the need for them.

- Extends URLSearchParams API to include operations for combining
different URLSearchParams objects:
These new methods include:
setAll(otherParams): performs `this.set(key, values[0])` for each
key/value-list pair in `otherParams`
appendAll(otherParams): performs `this.append(key, values)` for
each key/value-list pair in `otherParams`
replaceAll(otherParams): for each key/value-list pair in
`otherParams`, replaces current set of values for `key` with
a copy of the list of values.
- RequestOptions do not merge search params automatically (because
there are multiple ways to do this). Instead, they replace any
existing `search` field if `search` is provided. Explicit merging
is required if merging is desirable.
- Some extra test coverage added.

This requires delicate handling of type definitions which collide, because
we use TypeScript-provided lib.d.ts for --target=es5 and lib.es6.d.ts for
--target=es6.
We need to include our polyfill typings only in the --target=es5 case,
and the usages have to be consistent with lib.es6.d.ts.
Also starting with this change we now typecheck additional modules,
so this fixes a bunch of wrong typings which were never checked before.
Fixes#3178
Formatting code requires time and memory during the build -- do not do
it unless explicitly requested via a parameter to the transformer.
Add an entry to the
[wiki](https://github.com/angular/angular/wiki/Angular-2-Dart-Transformer)
describing the added parameter.
Previously, the error messages coming out of the Dart transformer were
opaque when those errors came from the analyzer (for example, analyzer
parse errors). Log more useful errors when they are caught by the
transform code.
Previously I added parens everywhere to make this @proxy() because our typing indicated
it was a function that returned a decorator, but this breaks dart. Instead, the typing needs
to be changed.
Fixes#3494
Promise used to be typed as any, giving incorrect results. This change
fixes places that were incorrectly typed and re-exports the actual
Promise type from es6-promise.
It also fixes a series of compilation errors discovered/triggered by
this change.
BREAKING CHANGE
Previously, if an element had a property, Angular would update that property even if there was a directive placed on the same element with the same property. Now, the directive would have to explicitly update the native elmement by either using hostProperties or the renderer.
This change also makes us compliant with 1.6.0-dev compiler,
so we can do some experiments with apps that use 1.6 features
and compile against Angular.
We should probably add a travis build for 1.6 so we stay compatible
with both versions.
Introduces the injectable `TemplateCloner` that can be configured via the new token `MAX_IN_MEMORY_ELEMENTS_PER_TEMPLATE_TOKEN`.

First part of #3364
Originally we ran gulp enforce-format at the beginning of the build.
This was annoying because you came back from lunch to find that no tests
ran so you have to start your PR over.
Then we changed it to run the linters at the end. This is annoying because
you might be ready to merge to master, and could have fixed the lint
issues immediately, but now much wait for another PR.
The solution is to run the lint checks in another build. This marks
your PR red very early, but you still get the feedback of whether the
tests are passing.

BREAKING CHANGES:
- `ShadowDomStrategy` was removed. To specify the encapsulation of a component use `@View(encapsulation: ViewEncapsulation.NONE | ViewEncapsulation.EMULATED | ViewEncapsulation.NATIVE)`
- The default encapsulation strategy is now `ViewEncapsulation.EMULATED` if a component contains styles and `ViewEncapsulation.NONE` if it does not. Before this was always `NONE`.
- `ViewLoader` now returns the template as a string and the styles as a separate array
Call new `(de)hydrateDirectives` methods from `(de)hydrate`. Add a null
implementation in `AbstractChangeDetector` and only override if
necessary for the specific change detector.
Update to #3248
Create `looseNotIdentical => !looseIdentical`, which will save a lot of
unnecessary '!' characters in generated change detectors.

Reverted from commit 35597a8349
This style change makes the docs look nicer but clang-format doesn't
like it. @mhevery perhaps we can tweak the clang-format rules for this?
Previously, `uninitialized()` was a method, requiring a call as well as
two extra characters everywhere it was used.
Make this value a variable, saving the characters and avoiding the
method call to get its value.
This change also removes the export of `uninitialized` from
change_detect.ts, which is technically a breaking change, however
`uninitialized` is an implementation detail and nobody should be using
it in app logic. By convention, apps should not be importing from files
under `src/`.
Update to #3248.
We discussed last week that our build has been steadily getting longer.
We should track the time so we can easily notice that it went up and
find the culprit.
This hooks us up to https://buildtimetrend.herokuapp.com/ which seems
capable and very quick to setup. We can easily gather the data and
then evaluate the dashboard.
Note that we want to have two different webhooks, and only notify gitter
on transitions, but we want to have timing for all builds, since a
series of passing builds might have a big jump in build time in the middle.
I don't see how to do this with travis.yml so I've overnotified gitter.
Fixes#3001
BREAKING CHANGE:
View renderer used to take normalized CSS class names (ex. fooBar for foo-bar).

Use `NameRegistry` for both JS Jit & Dart pre-generated detectors.
Making progress on #3248
Previously, the compiler would detect cycles where there were none just because of other components that were compiled in parallel. Furthermore, the way ProtoView merging was triggered could result into early exits resulting in errors when trying to instantiate ProtoViews.
Fixes#3206Closes#3211
BREAKING CHANGE
Previously it was possible to pass a custom error reporter to bootstrap, which was used only during the construction of Injector. This had limited utility, so this capability has been removed.
In 2e4a2a0e5a we removed the `@public` tags but the `addJadeDataDocsProcessor`
was still relying upon them being there to identify whether a doc should
be included in the public docs.
Instead we should just check for the doc not being marked with the
`@private` tag.
Closes#3212
BREAKING CHANGES:
Dart applications and TypeScript applications meant to transpile to Dart must now
import `package:angular2/bootstrap.dart` instead of `package:angular2/angular2.dart`
in their bootstrap code. `package:angular2/angular2.dart` no longer export the
bootstrap function. The transformer rewrites imports of `bootstrap.dart` and calls
to `bootstrap` to `bootstrap_static.dart` and `bootstrapStatic` respectively.
When a `Directive` implements a lifecycle interface (e.g. `OnChange` or
`OnInit`), populate its `lifecycle` property if not already populated).
Closes#3181
Static binary component tree of depth 10, i.e. 1024 components.
Current numbers for `pureScriptTime` are:
JavaScript:
Baseline: 27.10+-9%
Ng2: 26.84+-8%
Ng1: 55.30+-14%
Dart:
Baseline: 30.13+-4%
Ng2: 45.94+-3%
Ng1: 128.88+-10%
I.e. in JS we are same speed as baseline right now!
Some background: We had a recent change in the compiler that merges components into their parents already during compilation (#2529). This made Ng2 2x faster in this benchmark (before the Ng2 JS time was 49.59+-14%ms).
Closes#3196
Don't precompile Dart2JS for pull requests, instead serve the dart
sources with pub serve. We were already testing with Dartium so
all we lose is some test coverage of defects exposed only by the
Dart2JS transpiler.
This still runs the dart transformer.
Fixes#3030
BREAKING CHANGE
The @Parent annotation has been removed. Use @Ancestor instead.
@Parent was used to enforce a particular DOM structure (e.g., a pane component is a direct child of the tabs component).
DI is not the right mechanism to do it. We should enforce it using schema instead.
The Angular 2 render compiler can get out of sync between its transformer
execution and its runtime execution, leading to incorrect change detectors with
out-of-order property values. Stable sorting solves this problem (temporarily).
Angular fetches template HTML files outside of the browser's normal parsing flow. As a result, URLs in template files are interpreted relative to the root application, when the components defined by the template files are inserted into the DOM. This change enables a template author to prefix URLs with the string $baseUrl, which will be replaced with the relative base path of the template file.
So for an example template loaded from /component/foo/template.html:
<img src="$baseUrl/logo.png" />
becomes:
<img src="/component/foo/logo.png" />
Addresses #2384.
Due to #3019 we have to check whether a property exists on a DOM element
not before runtime of the application.
Previously, we did this check in JavaScript, making all property values
go through dart js interop. However, this is slow for complex objects.
This commit changes this behavior to first check whether the property exists
before sending the property value to the DOM element via js interop.
Closes#3149
Previously, calls to getBaseHref used document.baseURI, which defaults
to the current path in the absence of a base element in the document.
This leads to surprising behavior.
With this change, getBaseHref returns null when a base element is not
present in the document.
Implement deferred libraries to work with dependency injection and other
angular codegen. This is done by not initializing the library in the parent
ng_deps file when it is declared as deferred, rewriting the import and,
chaining a future that initializes the library in any files that are using
deferred libraries which need angular codegen.
BREAKING CHANGES:
`ViewManager.createView` / `ViewContainerRef.create` have been split into 2 methods:
- `createHostView` which takes dynamically created bindings
- `createEmbeddedView` which takes the newly introduced `TemplateRef`
The new type `TemplateRef` is the combination of a `ProtoViewRef` and and `ElementRef`
from the same place. Use `TemplateRef` when working with embedded views in
`ng-if`, `ng-for`, ... instead of `ProtoViewRef`.
Also, `ProtoViewRef` is no more injectable, but `TemplateRef` is.
First part of #1989 to clean up manual content projection.
Closes#3114
Fix sort order for reflective imports in reflection_remover/rewriter.dart.
Currently there is only one import so the sort order happens to be correct,
but if another one is added the rewrite code will break.
Remove reflector parameter from initReflector method to simplify ng_deps for reflection
initialization. It wasn't used and was added for testability, but wasn't used. This
keeps the interface simplier.
In Dart, '$' indicates the beginning of an interpolation.
- Escapes '$' in strings when generating change detector classes.
- Adds a unit test to cover this case.
The pub publish process was not following through with publishing
packages because the -f flag was not be provided to pub publish,
causing the process to prompt for confirmation before publishing,
which was causing the pub_publish.sh script to skip publishing.
Closes#3077
Closes#2529
BREAKING CHANGES:
- shadow dom emulation no longer
supports the `<content>` tag. Use the new `<ng-content>` instead
(works with all shadow dom strategies).
- removed `DomRenderer.setViewRootNodes` and `AppViewManager.getComponentView`
-> use `DomRenderer.getNativeElementSync(elementRef)` and change shadow dom directly
- the `Renderer` interface has changed:
* `createView` now also has to support sub views
* the notion of a container has been removed. Instead, the renderer has
to implement methods to attach views next to elements or other views.
* a RenderView now contains multiple RenderFragments. Fragments
are used to move DOM nodes around.
Internal changes / design changes:
- Introduce notion of view fragments on render side
- DomProtoViews and DomViews on render side are merged,
AppProtoViews are not merged, AppViews are partially merged
(they share arrays with the other merged AppViews but we keep
individual AppView instances for now).
- DomProtoViews always have a `<template>` element as root
* needed for storing subviews
* we have less chunks of DOM to clone now
- remove fake ElementBinder / Bound element for root text bindings
and model them explicitly. This removes a lot of special cases we had!
- AppView shares data with nested component views
- some methods in AppViewManager (create, hydrate, dehydrate) are iterative now
* now possible as we have all child AppViews / ElementRefs already in an array!
By binding the token `DOM_REFLECT_PROPERTIES_AS_ATTRIBUTES` provided by
the dom_renderer module to `true` in the root injector (i.e. bootstrap()),
all elements whose properties are set by angular will be reflected as
attributes with the prefix "ng-reflect-".
Fixes#2910
Relying on ASI (automatic semicolon insertion)
is allowed in TypeScript because JavaScript allows
it. However, when we run clang-format it doesn’t
understand that these statements are terminated
with a newline and changes the indentation, in bad
cases even breaking the code.
Fixes#817
When we are creating a type definition file for a class has a private constructor,
we convert it to a combination of an instance of a concrete type with no constructor and an interface that contains the other methods.
When this happens, we must also convert the class's heritage from
`implements` to `extends` since interfaces cannot implement other interfaces
or classes.
Fixes a problem with #2996Closes#3002
This fixes several minor indentation issues (instanceof precendence,
type declaration specificity, template string length calculation).
This should also fix some flip-flop situations with template strings.
This means that we can now run just the d.ts file generation by running:
```bash
gulp docs/typings
```
In addition the type definition generation was messing with the other docs tasks
so separating it also fixes problems there.
BREAKING CHANGE:
This change renames all instances of PipeRegistry to Pipes.
As part of this change, the former "defaultPipes" export is
now a Pipes instance, instead of a map. The map that was previously
called "defaultPipes" no longer exists, but may be accessed via
defaultPipes.config.
This is its own commit so that tools have an easier time of preserving
history of the file, by keeping the diff between pipes.ts and
pipe_registry.ts minimal.
Also moved pipe_registry_spec.ts
second attempt after rollback of https://github.com/angular/angular/pull/2946
After each successful build in the dart stable variant, this uploads just enough of the dart
artifacts to mirror what we would push to pub.
By uploading the files instead of a zip, this lets dart users depend on an unreleased snapshot
of angular2, and lets us easily fetch the dart artifacts for sync into google3
without having to re-build (potentially in a subtly different environment).
This doesn't upload anything for pull requests.
Travis is currently stalling, presumably it takes too long to upload this many files.
Also it picks up the dart directory when deploying js, which looks like a bug
with multiple gcs providers, so just do dart for now.
This copies the dist/ folder for each successful travis run
to a google cloud storage bucket, under the SHA of the commit.
We only upload for submitted changes, not PRs.
We can use this to fetch the dart sources for each SHA
without having to re-build them, which is hard to reproduce
since the environment might differ (eg. different Dart SDK)
This change prevents the doc generation from crashing due to a missing module,
but perhaps we need to think of a way of being able to generate the angular.d.ts
file correctly in `gulp public_docs`, perhaps by removing the need for
angular2/angular2.api
The properties of the annotation classes are not really the public API.
Users will interact with these via a decorator, and the decorator
takes a single arg, typed with the args class. Thus the comment is
more useful on the arg class.
This also fixes the problem of intellisense/autocomplete not showing
the important docs as you fill in the properties in a decorator
declaration.
We had the same symbol exported as the interface
for Component decorator as well as the class for
Component annotation, and dgeni only showed the
latter.
Rename the interfaces for decorators with an ‘I’
prefix so they are retained in the .d.ts output.
Previously, when a return type was missing it
could have been any. But following #2746 we
require return types so remaining untyped returns
must be void.
this is no longer necessary and if anyone runs two gulp processes in parallel can actually cause
issues because once one of the processes ends, it delets the tmp dir which can affect the remaining
process
In non-transformed mode the funcOrValue check was enough, but once
transformed these all use the same function for getters, so we need
to also check the name.
BREAKING CHANGE:
The Http module previously would return RxJS Observables from method calls
of the Http class. In order to support Dart, the module was refactored to
return the EventEmitter abstraction instead, which does not contain the same
combinators or subscription semantics as an RxJS Observable. However, the
EventEmitter provides a toRx() method which will return an RxJS Subject,
providing the same subscription and combinator conveniences as were
available prior to this refactor.
This is temporary, until issue #2794 is resolved, when Observables will
again be returned directly from Http class methods.
Travis creates an empty node_modules directory when the cache is empty which confuses
our current script into thinking that it's ok to require fs-extra. While this is rare,
it's better not to depend on anything in node_modules when purging it, so I reimplemented
recorsive delete that we use to purse node_modules.
This is an alternative to #2778. All of the symlinks to packages directory within the test directory
are not needed for running tests, so we can safely remove them. This removes 80k files from the test directory
which significantly speeds up Karma.
Closes#2437
The BaseRequestOptions class is responsible for declaring default values,
while the RequestOptions class is merely responsible for setting values
based on values provided in the constructor.
BREAKING CHANGE: HttpFactory is no longer available.
This factory provided a function alternative to the `request` method of the
Http class, but added no real value. The additional factory required an
additional IHttp interface, an odd way to inject while preserving type information
(`@Inject(HttpFactory) http:IHttp`), and required additional documentation in the
http module.
Closes#2564
This change causes the build system to write a log file into the tmp folder after each build.
This file contains command line arguments that tell karma about all the added/changed/removed files
from the last build. Karma can then use this list instead of doing internal globbing which can be
very expensive especially for hte dart builds that contain thousands of files.
Closes#2437
The .nvmrc file is used by nvm if you don't specify a version. This lets us type Found '/Users/alexeagle/Projects/angular/.nvmrc' with version <0.12>
Now using node v0.12.2. It doesn't check that you are using the node version from the file, however, so this won't prevent version skew.
See https://github.com/creationix/nvm#usagecloses#1995
One of the non-angular broccoli plugins returns a weird object. We can't
assume that all trees meet the contract that we expect them to meet, so
we do a typecheck before storing the result of the rebuild.
Closes#2662
Don’t need to bundle them as they are already
present in G3. I.e. the benchpress bundle
only includes benchpress and Angular2 bits.
Also removes adding license headers for now,
as we only have one license.
This makes sure just running clang-format will use whatever version is
used in the project, by loading it from the closest node_modules folder.
It also moves the clang-format dependency to the top and explicitly
passes it to gulp-clang-format, giving us more control over the version
used.
Move the section from `CONTRIBUTING.md` (which should only be policy) to
`DEVELOPER.md` (which should document developer tooling).
Consolidates the whole thing a bit, and adjusts for the now always
installed `git clang-format` hook. Also mentions clang-format's lookup
behaviour.
This removes some, but not all, of the manual work needed to patch up our
.d.ts for pushing to DefinitelyTyped. Remaining manual steps are:
- some types still missing
- declaration of decorators
- remove destructuring args
See #2686.
add test in gulpfile which will compile a basic TS file with generated
angular2.d.ts to ensure generated d.ts is valid syntactic TS
Adds support for enums in .d.ts generation pipeline.
Removes renaming reexports in http module.
BREAKING CHANGES:
- rename `ElementRef.domElement` to `ElementRef.nativeElement`
- add `Renderer.getNativeElementSync` to make the app side
less dependent on the dom renderer.
- don’t use `ElementRef.nativeElement` in directives but
use the methods on `Renderer` directly.
- Removed `ElementRef.setAttribute`. Use `Renderer.setElementAttribute` instead.
Closes#2712
Last part of #2476Closes#2476
BREAKING CHANGES:
- Almost all methods in `Renderer` now take a `RenderElementRef` instead
of a `ViewRef` + `boundElementIndex`.
- These methods can be called with the `ElementRef` from the app side
directly.
Closes#2706
Related to #2476
In order to speedup the startup time of test.unit.js task, we are moving the circular dependency check into
a pre-test check that executes only on travis. Similarly we are moving the style check to a post-test check
that executes on travis.
This way if a circular dependency issue occurs, we find it before running tests on CI and if the code
is not formatted we fail the build only if all the tests pass.

BREAKING CHANGES:
- host actions don't take an expression as value any more but only a method name,
and assumes to get an array via the EventEmitter with the method arguments.
- Renderer.setElementProperty does not take `style.`/... prefixes any more.
Use the new methods `Renderer.setElementAttribute`, ... instead
Part of #2476Closes#2637
BREAKING CHANGE: compiler will throw on binding to non-existing properties.
Till now it was possible to have a binding to a non-existing property,
ex.: `<div [foo]="exp">`. From now on this is compilation error - any
property binding needs to have at least one associated property:
eaither on an HTML element or on any directive associated with a
given element (directives' properites need to be declared using the
`properties` field in the `@Directive` / `@Component` annotation).
Closes#2598
You can now run `gulp serve.e2e.prod` to instantiate a task that watches
and compiles example and module files into the prod directory in dist

At the moment we are not parsing param tags. This commit ignores them

While creating the ng_deps.dart file for a view inline the styleUrls attribute.
This copies the pattern used for templateUrl, aleviating the need to make an
XHR request for those resources.

Allows to add or remove previous siblings of text
interpolations (e.g. by added `<script>` tags for
content reproduction, or by removed `<style>` tags).
Also calculates correctly whether an element is
empty.
Fixes#2591
As the constructed objects have an any type, the
resulting containers are assignable to any type:
var x: Map<string, number> = new Map();
That is useful to avoid having to specify types
twice when declaration and assignment are in
different places.
These wrappers are not natively understood by
ts2dart. Removing them will improve Dart2JS
compilation due to fewer megamorphic calls to List
functions.
It also makes Angular code more succinct and
improves type safety in Angular due to better type
inference of the Array component type.
This change exposed several bugs in Angular.
StringMap really ought to always enforce a string
key, and also ought to have an index property.
This currently breaks too much code in Angular, so
should be fixed in a follow up Pull Request
separate from this.
Closes#2472Closes#2339
BREAKING CHANGE
- `Compiler.compile` has been removed, the only way to compile
components dynamically is via `Compiler.compileInHost`
- `DynamicComponentLoader.loadIntoExistingLocation` has changed:
* renamed into `loadIntoLocation`
* will always create the host element as well
* requires an element with a variable inside of the host component view
next to which it will load new component.
- `DynamicComponentLoader.loadNextToExistingLocation` was renamed into
`DynamicComponentLoader.loadNextToLocation`
- `DynamicComponentLoader.loadIntoNewLocation` is removed
* use `DynamicComponentLoader.loadNextToLocation` instead
and then move the view nodes
manually around via `DomRenderer.getRootNodes()`
- `AppViewManager.{create,destroy}Free{Host,Embedded}View` was removed
* use `AppViewManager.createViewInContainer` and then move the view nodes
manually around via `DomRenderer.getRootNodes()`
- `Renderer.detachFreeView` was removed. Use `DomRenderer.getRootNodes()`
to get the root nodes of a view and detach them manually.
Previously, class members were ordered alphabetically.
This change leaves it up to the class author to
determine the order in which they would like
properties and methods to appear in class
documentation, without having to create methods like
`zUnimportantMethod`.
Fixes#2569
Benchpress now prints out the best and worst frame time in addition to the percentage of frames that hit the target of 60fps.
It also renames 'meanFrameTime' to 'frameTime.mean'. That way, all frameTime metrics start with a common suffix and will be grouped together in the console reporter.

There are upcoming changes to the way we generate
and verify setters so more test are needed to cover
all the corner cases that are being handled today.
Closes#2559
Enable pregenerated (for Dart) and JIT (for Js) change detectors when
possible. Previously we would always use `DynamicChangeDetector`s, but
these cause megamorphic calls and are therefore much slower.
Closes#502
The `build.http.example` task was removed from gulp and replaced by another task, but a reference to the task was not removed from `test_e2e_dart.sh`.
Fixes#2509
Uglify files related to angular2.min.js bundle in one task.
Include reflect.js in the bundle, which was previously missing. Minify reflect.js, zone.js, and angular2.min.js using uglify.
Move all remaining unit tests for change detectors to exercise Dart
pre-generated change detectors as well as `dynamic` and `JIT` change
detectors.
See #502
More the change detect tests that exercise various detection modes to
use the Dart pre-generated change detectors in addition to the `dynamic`
and `JIT` change detectors.
See #502
This implementation only works in JavaScript, while the Observable transpilation
story gets worked out. Right now, the service just makes a simple request,
and returns an Observable of Response.
Additional functionality will be captured in separate issues.
Fixes#2028
Once we add support for addedPaths then this implementation will be significantly faster than the original.
In the meantime we benefit from having stable output directory which solves issues with certain files disappearing
during rebuild of a tree that contains flatten and mergeTree plugins.
Closes#2418
System.js seems detect an empty file as global and choke on exporting
symbols from angular2/angular2 (possibly a bug in system.js).
As temporary measure we make sure that the file has some (fake) runtime
code left.
Closes: #2343
- Modify change detectors to `throw` when attempting to detect changes
on a dehydrated detector.
- Modify `DynamicChagneDetector` to use `null` for the `context` of a
dehydrated detector.
Note that this also removes the `components` option from `RouteConfig`.
This functionality will be reintroduced with the more general `//` routing.
See #2329 for more details.
Update the transformer's `TemplateCompiler` phase to avoid setting
`reflector.reflectionCapabilities`, allowing asynchronous
operations, and restoring the original value, which allows
`reflector.reflectionCapabilities` to get into a bad state.
This requires some hacks, documented in
https://docs.google.com/document/d/1nNebWTiLzz5ePcit_bjZPtaiSIFU4EsQKUlX7LX0c0A/edit
Changes:
- include subtyping info in angular2.d.ts by adding 'extends supertype'
- export missing symbols needed transitively by angular2/angular2
- because of decorator/annotation mismatch, we can't export these to applications.
So I've added a separate angular2.api.ts file to re-export specifically to .d.ts
generation.
- Hack to remove aliases introduced by 'import * as alias' syntax
- Hack to deal with Error still an interface
note that we require users to install the transitive dependencies - this is how TSD works.
It is very noisy, especially when multiple trees are used. Since the
tree differ is fairly quick, it's not measuring the real costs of a
plugin anyhow.
Closes#2378
Add a type for the `context` field in Dart's pre-generated change
detectors. This requires slight changes to set the dehydrated value of
`context` to `null` rather than `ChangeDetectionUtil.uninitialized()`,
which was its former dehydrated state.
Mirror these chagnes as closely as possible in the
`ChangeDetectionJITGenerator` to allow easier maintenance.
Closes#2070
To support interface-based lifecycle methods (#2220), we need to be able
to query for the `interface`s a class supports. Record implemented
interfaces to allow mirror-less querying at runtime.
Closes#2204
Replaces the multiple arrays of `DomView`
by a single array with `DomElement`s.
Note: this commit does not show a performance regression
(tested against the tree benchmark locally).
clang-format 1.0.17 substantially improves formatting for fat arrow functions
and array literal detection. It also fixes a number of minor formatting issues.
Free embedded views are view instances that are created
logically in the same was as views of a ViewContainer,
but their dom nodes are not attached.
BREAKING CHANGE:
- `Renderer.detachFreeHostView` was renamed to
`Renderer.detachFreeView`
- `DomRenderer.getHostElement()` was generalized into
`DomRenderer.getRootNodes()`
Largetable benchmark with `interpolationAttr` and 200 rows / 20 columns:
Time for destroy/create pair dropped from about 1260ms to about 150ms.
Related to #2298, but does not really fix it as we are still slow
if people are using `<content>`.
Closes#2297
It was confusing because the test.unit.dart task does ignore the initial, and
the logger was hardcoded to always ignore the first task, leading to the appearance
that a run was happening twice for no reason.
Also, fixed the "fake ignoreInitial" handling to not rely on a fake event, which
is not necessary.
Closes#2101
The semantics between ES6 `Promise#all` and Dart's `Future#wait` are
different for values that are not `Promise`/`Future`s. In ES6,
non-`Promise` values are immediately completed to their current value.
In Dart, non-`Future` values cause an error.
Updated Dart's `PromiseWrapper#all` implementation to conform to the ES6
spec.
Use the `ProtoViewDto` created by the render `Compiler` to create a
`ChangeDetectorDefinition`.
From there, generate a subclass of `AbstractChangeDetector` for each
`ChangeDetectorDefinition`.
Run some basic unit tests for the dynamic and JIT change detectors on
pre-generated change detectors.
Usage: bootstrap the app with the special binding
`ELEMENT_PROBE_CONFIG` from `angular2/debug`.
This will provide a global method `ngProbe(element)` that
will expose a `DebugElement` with directive instances, ... on it.
During tests that use Angular's test injector, the probe is
enabled by default. The `DebugElement ` can be retrieved via the
function `inspectDomElement` of `angular2/debug`. Note
that the `TestComponentBuilder` already returns `DebugElement `s.
Closes#1992
When a template contains bound text nodes as root nodes,
we used to store the document fragment that we got from
cloning `template.content`. However, this fragment will be
empty as soon as the view gets attached. Now we store
`null` instead of the document fragment in this case.
Also groups the 3 cases in `_createView` so they are easier to
understand.
Previously we assumed that all input and ouput paths for broccoli trees are immutable, that turned out to be
incorrect.
By adding a tree stabilizer plugin in front of each diffing plugin, we ensure that the input trees
are stable. The stabilization is done via symlinks which is super cheap on platforms that support
symlinks. On Windows we currently copy the whole input directory, which is far from ideal. We should
investagate if using move operation on Windows is ok in the future to improve performance.
Closes#2051
Removes `.ng_deps.dart` files which
1. Do not register any `@Injectable` classes
2. Do not call `initReflector` on any other `.ng_deps.dart` files.

Note: We can’t write a unit test for this as our unit tests
are running in Dartium, where the error does not occur.
However, we previously had a failure in our e2e tests
in `hello_world/index_dynamic.html`

But do it during the build process for cjs.
Right now we only need this when we transpile from ts

the rest.

discussion list or [StackOverflow][stackoverflow]. We are also available on [Gitter][gitter].
Do not open issues for general support questions as we want to keep GitHub issues for bug reports and feature requests. You've got much better chances of getting your question answered on [Stack Overflow](https://stackoverflow.com/questions/tagged/angular) where the questions should be tagged with tag `angular`.

Stack Overflow is a much better place to ask questions since:
- there are thousands of people willing to help on Stack Overflow
- questions and answers stay available for public viewing so your question / answer might help someone else
- Stack Overflow's voting system assures that the best answers are prominently visible.
To save your and our time, we will systematically close all issues that are requests for general support and redirect people to Stack Overflow.
If you would like to chat about the question in real-time, you can reach out via [our gitter channel][gitter].
## <a name="issue"></a> Found a Bug?
If you find a bug in the source code, you can help us by
[submitting an issue](#submit-issue) to our [GitHub Repository][github]. Even better, you can
[submit a Pull Request](#submit-pr) with a fix.
## <a name="feature"></a> Want a Feature?
You can *request* a new feature by [submitting an issue](#submit-issue) to our [GitHub
Repository][github]. If you would like to *implement* a new feature then consider what kind of
change it is:
## <a name="feature"></a> Missing a Feature?
You can *request* a new feature by [submitting an issue](#submit-issue) to our GitHub
Repository. If you would like to *implement* a new feature, please submit an issue with
a proposal for your work first, to be sure that we can use it.
Please consider what kind of change it is:
* For a **Major Feature**, first open an issue and outline your proposal so that it can be
discussed. This will also allow us to better coordinate our efforts, prevent duplication of work,
and help you to craft the change so that it is successfully accepted into the project.
* **Small Features** can be crafted and directly [submitted as a Pull Request](#submit-pr).
## <a name="docs"></a> Want a Doc Fix?
If you want to help improve the docs, then consider what kind of improvement it is:

minimize duplication of effort. Before starting, check out the issue queue for
Comment on an issue to let others know what you're working on, or [create a new issue](#submit-issue)
if your work doesn't fit within the scope of any of the existing doc issues.
Please build and test the documentation before [submitting the Pull Request](#submit-pr), to be sure
you haven't accidentally introduced any layout or formatting issues. Also ensure that your commit
message is labeled "docs" and follows the [Commit Message Guidelines](#commit) given below.
* For **Small Changes**, there is no need to file an issue first. Simply [submit a Pull Request](#submit-pr).
## <a name="submit"></a> Submission Guidelines
### <a name="submit-issue"></a> Submitting an Issue
Before you submit an issue, search the archive, maybe your question was already answered.
If your issue appears to be a bug, and hasn't been reported, open a new issue.
Help us to maximize the effort we can spend fixing issues and adding new
features, by not reporting duplicate issues. Providing the following information will increase the
chances of your issue being dealt with quickly:
Before you submit an issue, please search the issue tracker, maybe an issue for your problem already exists and the discussion might inform you of workarounds readily available.
We want to fix all the issues as soon as possible, but before fixing a bug we need to reproduce and confirm it. In order to reproduce bugs, we will systematically ask you to provide a minimal reproduction scenario using http://plnkr.co. Having a live, reproducible scenario gives us a wealth of important information without going back & forth to you with additional questions like:
- version of Angular used
- 3rd-party libraries and their versions
- and most importantly - a use-case that fails
A minimal reproduce scenario using http://plnkr.co/ allows us to quickly confirm a bug (or point out coding problem) as well as confirm that we are fixing the right problem. If plunker is not a suitable way to demonstrate the problem (for example for issues related to our npm packaging), please create a standalone git repository demonstrating the problem.
We will be insisting on a minimal reproduce scenario in order to save maintainers time and ultimately be able to fix more bugs. Interestingly, from our experience users often find coding problems themselves while preparing a minimal plunk. We understand that sometimes it might be hard to extract essentials bits of code from a larger code-base but we really need to isolate the problem before we can fix it.
Unfortunately, we are not able to investigate / fix bugs without a minimal reproduction, so if we don't hear back from you we are going to close an issue that doesn't have enough info to be reproduced.
You can file new issues by filling out our [new issue form](https://github.com/angular/angular/issues/new).
* **Overview of the Issue** - if an error is being thrown a non-minified stack trace helps
* **Motivation for or Use Case** - explain why this is a bug for you
* **Angular Version(s)** - is it a regression?
* **Browsers and Operating System** - is this a problem with all browsers?
* **Reproduce the Error** - provide a live example (using [Plunker][plunker],
[JSFiddle][jsfiddle] or [Runnable][runnable]) or a unambiguous set of steps.
* **Related Issues** - has a similar issue been reported before?
* **Suggest a Fix** - if you can't fix the bug yourself, perhaps you can point to what might be
causing the problem (line of code or commit)

* **style**: Changes that do not affect the meaning of the code (white-space, formatting, missing semi-colons, etc)
* **test**: Adding missing tests or correcting existing tests
### Scope
The scope could be anything specifying place of the commit change. For example
`Compiler`, `ElementInjector`, etc.
The scope should be the name of the npm package affected (as perceived by the person reading the changelog generated from commit messages.
The following is the list of supported scopes:
* **animations**
* **common**
* **compiler**
* **compiler-cli**
* **core**
* **elements**
* **forms**
* **http**
* **language-service**
* **platform-browser**
* **platform-browser-dynamic**
* **platform-server**
* **platform-webworker**
* **platform-webworker-dynamic**
* **router**
* **service-worker**
* **upgrade**
There are currently a few exceptions to the "use package name" rule:
* **packaging**: used for changes that change the npm package layout in all of our packages, e.g. public path changes, package.json changes done to all packages, d.ts file/format changes, changes to bundles, etc.
* **changelog**: used for updating the release notes in CHANGELOG.md
* **aio**: used for docs-app (angular.io) related changes within the /aio directory of the repo
* none/empty string: useful for `style`, `test` and `refactor` changes that are done across all packages (e.g. `style: add missing semicolons`)

**Optional**: In this document, we make use of project local `npm` package scripts and binaries
(stored under `./node_modules/.bin`) by prefixing these command invocations with `$(npm bin)`; in
particular `gulp` and `protractor` commands. If you prefer, you can drop this path prefix by either:
*Option 1*: globally installing these two packages as follows:
*`npm install -g gulp` (you might need to prefix this command with `sudo`)
*`npm install -g protractor` (you might need to prefix this command with `sudo`)
Since global installs can become stale, and required versions can vary by project, we avoid their
use in these instructions.
*Option 2*: defining a bash alias like `alias nbin='PATH=$(npm bin):$PATH'` as detailed in this
[Stackoverflow answer](http://stackoverflow.com/questions/9679932/how-to-use-package-installed-locally-in-node-modules/15157360#15157360) and used like this: e.g., `nbin gulp build`.
## Build commands
To build Angular and prepare tests, run:
```shell
$(npm bin)/gulp build
```
Notes:
* Results are put in the `dist` folder.
* This will also run `pub get` for the subfolders in `modules` and run `dartanalyzer` for
every file that matches `<module>/src/<module>.dart`, e.g. `di/src/di.dart`.
You can selectively build either the JS or Dart versions as follows:
*`$(npm bin)/gulp build.js`
*`$(npm bin)/gulp build.dart`
To clean out the `dist` folder, run:
```shell
$(npm bin)/gulp clean
```
## Running Tests Locally
### Full test suite
*`npm test`: full test suite for both JS and Dart versions of Angular. These are the same tests
that run on Travis.
You can selectively run either the JS or Dart versions as follows:
*`$(npm bin)/gulp test.all.js`
*`$(npm bin)/gulp test.all.dart`
### Unit tests
You can run just the unit tests as follows:
*`$(npm bin)/gulp test.unit.js`: JS tests in a browser; runs in **watch mode** (i.e.
watches the test files for changes and re-runs tests when files are updated).
* `$(npm bin)/gulp test.unit.cjs`: JS tests in NodeJS; runs in **watch mode**.
* `$(npm bin)/gulp test.unit.dart`: Dart tests in Dartium; runs in **watch mode**.
If you prefer running tests in "single-run" mode rather than watch mode use:
*`$(npm bin)/gulp test.unit.js/ci`
*`$(npm bin)/gulp test.unit.cjs/ci`
*`$(npm bin)/gulp test.unit.dart/ci`
The task updates the dist folder with transpiled code whenever a source or test file changes, and
Karma is run against the new output.
**Note**: If you want to only run a single test you can alter the test you wish to run by changing
`it` to `iit` or `describe` to `ddescribe`. This will only run that individual test and make it
much easier to debug. `xit` and `xdescribe` can also be useful to exclude a test and a group of
tests respectively.
### E2e tests
1.`$(npm bin)/gulp build.js.cjs` (builds benchpress and tests into `dist/js/cjs` folder).
2.`$(npm bin)/gulp serve.js.prod serve.js.dart2js` (runs a local webserver).
We use [clang-format](http://clang.llvm.org/docs/ClangFormat.html) to automatically enforce code style for our TypeScript code. This allows us to focus our code reviews more on the content, and less on style nit-picking. It also lets us encode our style guide in the `.clang-format` file in the repository, allowing many tools and editors to share our settings.
To check the formatting of your code, run
gulp check-format
Note that the continuous build on Travis runs `gulp enforce-format`. Unlike the `check-format` task, this will actually fail the build if files aren't formatted according to the style guide.
Your life will be easier if you include the formatter in your standard workflow. Otherwise, you'll likely forget to check the formatting, and waste time waiting for a build on Travis that fails due to some whitespace difference.
* **git pre-commit hook** is available at [llvm.org](https://llvm.org/svn/llvm-project/cfe/trunk/tools/clang-format/git-clang-format). This will automatically format your delta regions when you commit a change. To install, first patch this file to add `.ts` to the `default_extensions` section. Then copy the file somewhere in your path, for example, `/usr/local/git/current/bin/git-clang-format`. Make sure it is executable. Then, in the angular repo, run

guidelines for [contributing][contributing].
guidelines for [contributing][contributing] and then check out one of our issues in the [hotlist: community-help](https://github.com/angular/angular/labels/hotlist%3A%20community-help).
Everything in this folder is part of the documentation project. This includes
* the web site for displaying the documentation
* the dgeni configuration for converting source files to rendered files that can be viewed in the web site.
* the tooling for setting up examples for development; and generating live-example and zip files from the examples.
## Developer tasks
We use `yarn` to manage the dependencies and to run build tasks.
You should run all these tasks from the `angular/aio` folder.
Here are the most important tasks you might need to use:
*`yarn` - install all the dependencies.
*`yarn setup` - install all the dependencies, boilerplate, stackblitz, zips and run dgeni on the docs.
*`yarn setup-local` - same as `setup`, but use the locally built Angular packages for aio and docs examples boilerplate.
*`yarn build` - create a production build of the application (after installing dependencies, boilerplate, etc).
*`yarn build-local` - same as `build`, but use `setup-local` instead of `setup`.
*`yarn start` - run a development web server that watches the files; then builds the doc-viewer and reloads the page, as necessary.
*`yarn serve-and-sync` - run both the `docs-watch` and `start` in the same console.
*`yarn lint` - check that the doc-viewer code follows our style rules.
*`yarn test` - run all the unit tests once.
*`yarn test --watch` - watch all the source files, for the doc-viewer, and run all the unit tests when any change.
*`yarn e2e` - run all the e2e tests for the doc-viewer.
*`yarn docs` - generate all the docs from the source files.
*`yarn docs-watch` - watch the Angular source and the docs files and run a short-circuited doc-gen for the docs that changed.
*`yarn docs-lint` - check that the doc gen code follows our style rules.
*`yarn docs-test` - run the unit tests for the doc generation code.
*`yarn boilerplate:add` - generate all the boilerplate code for the examples, so that they can be run locally. Add the option `--local` to use your local version of Angular contained in the "dist" folder.
*`yarn boilerplate:remove` - remove all the boilerplate code that was added via `yarn boilerplate:add`.
*`yarn generate-stackblitz` - generate the stackblitz files that are used by the `live-example` tags in the docs.
*`yarn generate-zips` - generate the zip files from the examples. Zip available via the `live-example` tags in the docs.
*`yarn example-e2e` - run all e2e tests for examples
-`yarn example-e2e --setup` - force webdriver update & other setup, then run tests
-`yarn example-e2e --filter=foo` - limit e2e tests to those containing the word "foo"
-`yarn example-e2e --setup --local` - run e2e tests with the local version of Angular contained in the "dist" folder
*`yarn build-ie-polyfills` - generates a js file of polyfills that can be loaded in Internet Explorer.
## Using ServiceWorker locally
Since abb36e3cb, running `yarn start --prod` will no longer set up the ServiceWorker, which
would require manually running `yarn sw-manifest` and `yarn sw-copy` (something that is not possible
with webpack serving the files from memory).
If you want to test ServiceWorker locally, you can use `yarn build` and serve the files in `dist/`
with `yarn http-server dist -p 4200`.
For more details see #16745.
## Guide to authoring
There are two types of content in the documentation:
* **API docs**: descriptions of the modules, classes, interfaces, decorators, etc that make up the Angular platform.
API docs are generated directly from the source code.
The source code is contained in TypeScript files, located in the `angular/packages` folder.
Each API item may have a preceding comment, which contains JSDoc style tags and content.
The content is written in markdown.
* **Other content**: guides, tutorials, and other marketing material.
All other content is written using markdown in text files, located in the `angular/aio/content` folder.
More specifically, there are sub-folders that contain particular types of content: guides, tutorial and marketing.
* **Code examples**: code examples need to be testable to ensure their accuracy.
Also, our examples have a specific look and feel and allow the user to copy the source code. For larger
examples they are rendered in a tabbed interface (e.g. template, HTML, and TypeScript on separate
tabs). Additionally, some are live examples, which provide links where the code can be edited, executed, and/or downloaded. For details on working with code examples, please read the [Code snippets](https://angular.io/guide/docs-style-guide#code-snippets), [Source code markup](https://angular.io/guide/docs-style-guide#source-code-markup), and [Live examples](https://angular.io/guide/docs-style-guide#live-examples) pages of the [Authors Style Guide](https://angular.io/guide/docs-style-guide).
We use the [dgeni](https://github.com/angular/dgeni) tool to convert these files into docs that can be viewed in the doc-viewer.
The [Authors Style Guide](https://angular.io/guide/docs-style-guide) prescribes guidelines for
writing guide pages, explains how to use the documentation classes and components, and how to markup sample source code to produce code snippets.
### Generating the complete docs
The main task for generating the docs is `yarn docs`. This will process all the source files (API and other),
extracting the documentation and generating JSON files that can be consumed by the doc-viewer.
### Partial doc generation for editors
Full doc generation can take up to one minute. That's too slow for efficient document creation and editing.
You can make small changes in a smart editor that displays formatted markdown:
>In VS Code, _Cmd-K, V_ opens markdown preview in side pane; _Cmd-B_ toggles left sidebar
You also want to see those changes displayed properly in the doc viewer
with a quick, edit/view cycle time.
For this purpose, use the `yarn docs-watch` task, which watches for changes to source files and only
re-processes the the files necessary to generate the docs that are related to the file that has changed.
Since this task takes shortcuts, it is much faster (often less than 1 second) but it won't produce full
fidelity content. For example, links to other docs and code examples may not render correctly. This is
most particularly noticed in links to other docs and in the embedded examples, which may not always render
correctly.
The general setup is as follows:
* Open a terminal, ensure the dependencies are installed; run an initial doc generation; then start the doc-viewer:
```bash
yarn setup
yarn start
```
* Open a second terminal and start watching the docs
```bash
yarn docs-watch
```
>Alternatively, try the consolidated `serve-and-sync` command that builds, watches and serves in the same terminal window
```bash
yarn serve-and-sync
```
* Open a browser at https://localhost:4200/ and navigate to the document on which you want to work.
You can automatically open the browser by using `yarn start -o` in the first terminal.
* Make changes to the page's associated doc or example files. Every time a file is saved, the doc will
be regenerated, the app will rebuild and the page will reload.
* If you get a build error complaining about examples or any other odd behavior, be sure to consult
the [Authors Style Guide](https://angular.io/guide/docs-style-guide).
