-# Change approvals
+## The `PR: merge` label and `presubmit-*` branches
 
-Change approvals in our monorepo are managed via [pullapprove.com](https://about.pullapprove.com/) and are configured via the `.pullapprove.yaml` file.
+We have automated the process for merging pull requests into master. Our goal is to minimize the disruption for
+Angular committers and also prevent breakages on master.
 
+When a PR has `pr_state: LGTM` and is ready to merge, you should add the `pr_action: merge` label.
+Currently (late 2015), we need to ensure that each PR will cleanly merge into the Google-internal version control,
+so the caretaker reviews the changes manually.
 
-# Merging
+After this review, the caretaker adds `zomg_admin: do_merge` which is restricted to admins only. 
+A robot running as [mary-poppins](https://github.com/mary-poppins)
+is notified that the label was added by an authorized person,
+and will create a new branch in the angular project, using the convention `presubmit-{username}-pr-{number}`.
 
-Once a change has all the approvals either the last approver or the PR author (if PR author has the project collaborator status) should mark the PR with "PR: merge" label.
-This signals to the caretaker that the PR should be merged.
+(Note: if the automation fails, committers can instead push the commits to a branch following this naming scheme.)
 
-# Who is the Caretaker?
+When a Travis build succeeds for a presubmit branch named following the convention,
+Travis will re-base the commits, merge to master, and close the PR automatically.
 
-See [this explanation](https://twitter.com/IgorMinar/status/799365744806854656).
+Finally, after merge `mary-poppins` removes the presubmit branch.
+
+## Administration
+
+The list of users who can trigger a merge by adding the `zomg_admin: do_merge` label is stored in our appengine app datastore.

+Before you submit an issue, search the archive, maybe your question was already answered.
 
-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.
+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:
 
-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 wealth of important information without going back & forth to you with additional questions like:
+* **Overview of the Issue** - if an error is being thrown a non-minified stack trace helps
+* **Angular Version** - what version of Angular is affected (e.g. 2.0.0-alpha.53)
+* **Motivation for or Use Case** - explain what are you trying to do and why the current behavior is a bug for you
+* **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)
 
-- 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 don't have enough info to be reproduced.

-used by AngularJS. In this system every issue is assigned frequency and
-severity based on which the total user pain score is calculated.
-
-Following is the definition of various frequency and severity levels:
-
-1. `freq(score): *` – How often does this issue come up? How many developers does this affect?
-    * low (1) - obscure issue affecting a handful of developers
-    * moderate (2) - impacts auxiliary usage patterns, only small number of applications are affected
-    * high (3) - impacts primary usage patterns, affecting most Angular apps
-    * critical (4) - impacts all Angular apps
-1. `severity(score): *` - How bad is the issue?
-    * inconvenience (1) - causes ugly/boilerplate code in apps
-    * confusing (2) - unexpected or inconsistent behavior; hard-to-debug
-    * broken expected use (3) - it's hard or impossible for a developer using Angular to accomplish something that Angular should be able to do
-    * memory leak (4)
-    * regression (5) - functionality that used to work no longer works in a new release due to an unintentional change

-# VM Setup - Set up secrets
-
-
-## Overview
-
-Necessary secrets:
-
-1. `GITHUB_TOKEN`
-   - Used for:
-     - Retrieving open PRs without rate-limiting.
-     - Retrieving PR author.
-     - Retrieving members of the `angular-core` team.
-     - Posting comments with preview links on PRs.
-
-2. `PREVIEW_DEPLOYMENT_TOKEN`
-   - Used for:
-     - Decoding the JWT tokens received with `/create-build` requests.
-
-**Note:**
-`TEST_GITHUB_TOKEN` and `TEST_PREVIEW_DEPLOYMENT_TOKEN` can also be created similar to their
-non-TEST counterparts and they will be loaded when running `aio-verify-setup`, but it is currently
-not clear if/how they can be used in tests.
-
-
-## Create secrets
-
-1. `GITHUB_TOKEN`
-   - Visit https://github.com/settings/tokens.
-   - Generate new token with the `public_repo` scope.
-
-2. `PREVIEW_DEPLOYMENT_TOKEN`
-   - Just generate a hard-to-guess character sequence.
-   - Add it to `.travis.yml` under `addons -> jwt -> secure`.
-     Can be added automatically with: `travis encrypt --add addons.jwt PREVIEW_DEPLOYMENT_TOKEN=<access-key>`
-
-**Note:**
-Due to [travis-ci/travis-ci#7223](https://github.com/travis-ci/travis-ci/issues/7223) it is not
-currently possible to use the JWT addon (as described above) for anything other than the
-`SAUCE_ACCESS_KEY` variable. You can get creative, though...
-
-**WARNING**
-TO avoid arbitrary uploads, make sure the `PREVIEW_DEPLOYMENT_TOKEN` is NOT printed in the Travis log.
-
-

-## Overview
-
-An Angular application consist largely of components and their HTML templates.
-Before the browser can render the application,
-the components and templates must be converted to executable JavaScript by the _Angular compiler_.
-<a href="https://www.youtube.com/watch?v=kW9cJsvcsGo" target="_blank">Watch compiler author Tobias Bosch explain the Angular Compiler</a> at AngularConnect 2016.You can compile the app in the browser, at runtime, as the application loads, using the **_Just-in-Time_ (JIT) compiler**.
-This is the standard development approach shown throughout the documentation.
-It's great .. but it has shortcomings.
-
-JIT compilation incurs a runtime performance penalty.
-Views take longer to render because of the in-browser compilation step.
-The application is bigger because it includes the Angular compiler
-and a lot of library code that the application won't actually need.
-Bigger apps take longer to transmit and are slower to load.
-
-Compilation can uncover many component-template binding errors.
-JIT compilation discovers them at runtime which is later than we'd like.
-
-The **_Ahead-of-Time_ (AOT) compiler** can catch template errors early and improve performance
-by compiling at build time as you'll learn in this chapter.
-
-
-
-{@a aot-jit}
-
-## _Ahead-of-time_ (AOT) vs _Just-in-time_ (JIT)
-
-There is actually only one Angular compiler. The difference between AOT and JIT is a matter of timing and tooling.
-With AOT, the compiler runs once at build time using one set of libraries;
-With JIT it runs every time for every user at runtime using a different set of libraries.
-
-### Why do AOT compilation?
-
-*Faster rendering*
-
-With AOT, the browser downloads a pre-compiled version of the application.
-The browser loads executable code so it can render the application immediately, without waiting to compile the app first.
-
-*Fewer asynchronous requests*
-
-The compiler _inlines_ external html templates and css style sheets within the application JavaScript,
-eliminating separate ajax requests for those source files.
-
-*Smaller Angular framework download size*
-
-There's no need to download the Angular compiler if the app is already compiled.
-The compiler is roughly half of Angular itself, so omitting it dramatically reduces the application payload.
-
-
-*Detect template errors earlier*
-
-The AOT compiler detects and reports template binding errors during the build step
-before users can see them.
-
-
-*Better security*
-
-AOT compiles HTML templates and components into JavaScript files long before they are served to the client.
-With no templates to read and no risky client-side HTML or JavaScript evaluation,
-there are fewer opportunities for injection attacks.

-{@a compile}
-
-## Compile with AOT
-
-### Prepare for offline compilation
-Take the <a href='../guide/setup.html'>Setup</a> as a starting point.
-A few minor changes to the lone `app.component` lead to these two class and html files:
-
-<md-tab-group>
-
-  <md-tab label="src/app/app.component.html">
-    {@example 'cb-aot-compiler/ts/src/app/app.component.html'}
-  </md-tab>
-
-
-  <md-tab label="src/app/app.component.ts">
-    {@example 'cb-aot-compiler/ts/src/app/app.component.ts'}
-  </md-tab>
-
-
-</md-tab-group>
-
-Install a few new npm dependencies with the following command:
-<code-example language="none" class="code-shell">
-  npm install @angular/compiler-cli @angular/platform-server --save
-</code-example>
-
-You will run the `ngc` compiler provided in the `@angular/compiler-cli` npm package
-instead of the TypeScript compiler (`tsc`).
-
-`ngc` is a drop-in replacement for `tsc` and is configured much the same way.
-
-`ngc` requires its own `tsconfig.json` with AOT-oriented settings.
-Copy the original `src/tsconfig.json` to a file called `tsconfig-aot.json` (on the project root),
-then modify it to look as follows.
-
-
-{@example 'cb-aot-compiler/ts/tsconfig-aot.json'}
-
-The `compilerOptions` section is unchanged except for one property.
-**Set the `module` to `es2015`**.
-This is important as explained later in the [Tree Shaking](#tree-shaking) section.
-
-What's really new is the `ngc` section at the bottom called `angularCompilerOptions`.
-Its `"genDir"` property tells the compiler
-to store the compiled output files in a new `aot` folder.
-
-The `"skipMetadataEmit" : true` property prevents the compiler from generating metadata files with the compiled application.
-Metadata files are not necessary when targeting TypeScript files, so there is no reason to include them.
-***Component-relative Template URLS***
-
-The AOT compiler requires that `@Component` URLS for external templates and css files be _component-relative_.
-That means that the value of `@Component.templateUrl` is a URL value _relative_ to the component class file.
-For example, an `'app.component.html'` URL means that the template file is a sibling of its companion `app.component.ts` file.
-
-While JIT app URLs are more flexible, stick with _component-relative_ URLs for compatibility with AOT compilation.
-
-JIT-compiled applications that use the SystemJS loader and _component-relative_ URLs *must set the* `@Component.moduleId` *property to* `module.id`.
-The `module` object is undefined when an AOT-compiled app runs.
-The app fails with a null reference error unless you assign a global `module` value in the `index.html` like this:
-
-{@example 'cb-aot-compiler/ts/src/index.html' region='moduleId'}
-
-
-Setting a global `module` is a temporary expedient.
-### Compiling the application
-
-Initiate AOT compilation from the command line using the previously installed `ngc` compiler by executing:
-<code-example language="none" class="code-shell">
-  node_modules/.bin/ngc -p tsconfig-aot.json
-</code-example>
-
-
-Windows users should surround the `ngc` command in double quotes:
-<code-example format='.'>
-  "node_modules/.bin/ngc" -p tsconfig-aot.json
-</code-example>
-
-`ngc` expects the `-p` switch to point to a `tsconfig.json` file or a folder containing a `tsconfig.json` file.
-
-After `ngc` completes, look for a collection of _NgFactory_ files in the `aot` folder (the folder specified as `genDir` in `tsconfig-aot.json`).
-
-These factory files are essential to the compiled application.
-Each component factory creates an instance of the component at runtime by combining the original class file
-and a JavaScript representation of the component's template.
-Note that the original component class is still referenced internally by the generated factory.
-The curious can open the `aot/app.component.ngfactory.ts` to see the original Angular template syntax
-in its intermediate, compiled-to-TypeScript form.
-
-JIT compilation generates these same _NgFactories_ in memory where they are largely invisible.
-AOT compilation reveals them as separate, physical files.
-
-
-~~~ {.alert.is-important}
-
-Do not edit the _NgFactories_! Re-compilation replaces these files and all edits will be lost.
-
-
-~~~
-
-
-
-{@a bootstrap}
-
-## Bootstrap
-
-The AOT path changes application bootstrapping.
-
-Instead of bootstrapping `AppModule`, you bootstrap the application with the generated module factory, `AppModuleNgFactory`.
-
-Make a copy of `main.ts` and name it `main-jit.ts`.
-This is the JIT version; set it aside as you may need it [later](#run-jit "Running with JIT").
-
-Open `main.ts` and convert it to AOT compilation.
-Switch from the `platformBrowserDynamic.bootstrap` used in JIT compilation to
-`platformBrowser().bootstrapModuleFactory` and pass in the AOT-generated `AppModuleNgFactory`.
-
-Here is AOT bootstrap in `main.ts` next to the original JIT version:
-
-<md-tab-group>
-
-  <md-tab label="src/main.ts">
-    {@example 'cb-aot-compiler/ts/src/main.ts'}
-  </md-tab>
-
-
-  <md-tab label="src/main-jit.ts">
-    {@example 'cb-aot-compiler/ts/src/main-jit.ts'}
-  </md-tab>
-
-
-</md-tab-group>
-
-Be sure to recompile with `ngc`!
-
-
-{@a tree-shaking}
-## Tree Shaking
-
-AOT compilation sets the stage for further optimization through a process called _Tree Shaking_.
-A Tree Shaker walks the dependency graph, top to bottom, and _shakes out_ unused code like
-dead needles in a Christmas tree.
-
-Tree Shaking can greatly reduce the downloaded size of the application
-by removing unused portions of both source and library code.
-In fact, most of the reduction in small apps comes from removing unreferenced Angular features.
-
-For example, this demo application doesn't use anything from the `@angular/forms` library.
-There is no reason to download Forms-related Angular code and tree shaking ensures that you don't.
-
-Tree Shaking and AOT compilation are separate steps.
-Tree Shaking can only target JavaScript code.
-AOT compilation converts more of the application to JavaScript,
-which in turn makes more of the application "Tree Shakable".
-
-### Rollup
-
-This cookbook illustrates a Tree Shaking utility called _Rollup_.
-
-Rollup statically analyzes the application by following the trail of `import` and `export` statements.
-It produces a final code _bundle_ that excludes code that is exported, but never imported.
-
-Rollup can only Tree Shake `ES2015` modules which have `import` and `export` statements.
-Recall that `tsconfig-aot.json` is configured to produce `ES2015` modules.
-It's not important that the code itself be written with `ES2015` syntax such as `class` and `const`.
-What matters is that the code uses ES `import` and `export` statements rather than `require` statements.Install the Rollup dependencies with this command:
-<code-example format='.'>
-  npm install rollup rollup-plugin-node-resolve rollup-plugin-commonjs rollup-plugin-uglify --save-dev
-</code-example>
-
-Next, create a configuration file (`rollup-config.js`)
-in the project root directory to tell Rollup how to process the application.
-The cookbook configuration file looks like this.
-
-
-{@example 'cb-aot-compiler/ts/rollup-config.js'}
-
-It tells Rollup that the app entry point is `src/app/main.js` .
-The `dest` attribute tells Rollup to create a bundle called `build.js` in the `dist` folder.
-It overrides the default `onwarn` method in order to skip annoying messages about the AOT compiler's use of the `this` keyword.
-
-Then there are plugins.
-### Rollup Plugins
-
-Optional plugins filter and transform the Rollup inputs and output.
-
-*RxJS*
-Rollup expects application source code to use `ES2015` modules.
-Not all external dependencies are published as `ES2015` modules.
-In fact, most are not. Many of them are published as _CommonJS_ modules.
-
-The _RxJs_ observable library is an essential Angular dependency published as an ES5 JavaScript _CommonJS_ module.
-
-Luckily there is a Rollup plugin that modifies _RxJs_
-to use the ES `import` and `export` statements that Rollup requires.
-Rollup then preserves in the final bundle the parts of `RxJS` referenced by the application.
-
-
-{@example 'cb-aot-compiler/ts/rollup-config.js' region='commonjs'}
-
-*Minification*
-
-Rollup Tree Shaking reduces code size considerably.  Minification makes it smaller still.
-This cookbook relies on the _uglify_ Rollup plugin to minify and mangle the code.
-
-
-{@example 'cb-aot-compiler/ts/rollup-config.js' region='uglify'}
-
-
-In a production setting, you would also enable gzip on the web server to compress
-the code into an even smaller package going over the wire.
-### Run Rollup
-Execute the Rollup process with this command:
-<code-example format='.'>
-  node_modules/.bin/rollup -c rollup-config.js
-</code-example>
-
-
-Windows users should surround the `rollup` command in double quotes:
-<code-example format='.'>
-  "node_modules/.bin/rollup"  -c rollup-config.js
-</code-example>
-
-
-
-{@a load}
-
-## Load the Bundle
-
-Loading the generated application bundle does not require a module loader like SystemJS.
-Remove the scripts that concern SystemJS.
-Instead, load the bundle file using a single `script` tag **_after_** the `</body>` tag:
-
-
-{@example 'cb-aot-compiler/ts/src/index.html' region='bundle'}
-
-
-
-{@a serve}
-
-## Serve the app
-
-You'll need a web server to host the application.
-Use the same _Lite Server_ employed elsewhere in the documentation:
-<code-example language="none" class="code-shell">
-  npm run lite
-</code-example>
-
-The server starts, launches a browser, and the app should appear.
-
-
-{@a source-code}
-
-## AOT QuickStart Source Code
-
-Here's the pertinent source code:
-<md-tab-group>
-
-  <md-tab label="src/app/app.component.html">
-    {@example 'cb-aot-compiler/ts/src/app/app.component.html'}
-  </md-tab>

-
-
-
-{@a workflow}
-
-## Workflow and convenience script
-
-You'll rebuild the AOT version of the application every time you make a change.
-Those _npm_ commands are long and difficult to remember.
-
-Add the following _npm_ convenience script to the `package.json` so you can compile and rollup in one command.Open a terminal window and try it.
-<code-example language="none" class="code-shell">
-  npm run build:aot  
-    
-</code-example>
-
-
-
-{@a run-jit}
-### And JIT too!
-
-AOT compilation and rollup together take several seconds.
-You may be able to develop iteratively a little faster with SystemJS and JIT.
-The same source code can be built both ways. Here's one way to do that.
-
-* Make a copy of `index.html` and call it `index-jit.html`.
-* Delete the script at the bottom of `index-jit.html` that loads `bundle.js`
-* Restore the SystemJS scripts like this:
-
-{@example 'cb-aot-compiler/ts/src/index-jit.html' region='jit'}
-
-Notice the slight change to the `system.import` which now specifies `src/app/main-jit`.
-That's the JIT version of the bootstrap file that we preserved [above](#bootstrap)
-Open a _different_ terminal window and enter.
-<code-example language="none" class="code-shell">
-  npm start
-</code-example>
-
-That compiles the app with JIT and launches the server.
-The server loads `index.html` which is still the AOT version (confirm in the browser console).
-Change the address bar to `index-jit.html` and it loads the JIT version (confirm in the browser console).
-
-Develop as usual.
-The server and TypeScript compiler are in "watch mode" so your changes are reflected immediately in the browser.
-
-To see those changes in AOT, switch to the original terminal and re-run `npm run build:aot`.
-When it finishes, go back to the browser and back-button to the AOT version in the (default) `index.html`.
-
-Now you can develop JIT and AOT, side-by-side.
-

-
-## Tour of Heroes
-
-The sample above is a trivial variation of the QuickStart app.
-In this section you apply what you've learned about AOT compilation and Tree Shaking
-to an app with more substance, the tutorial [_Tour of Heroes_](../tutorial/toh-pt6.html).
-
-### JIT in development, AOT in production
-
-Today AOT compilation and Tree Shaking take more time than is practical for development. That will change soon.
-For now, it's best to JIT compile in development and switch to AOT compilation before deploying to production.
-
-Fortunately, the source code can be compiled either way without change _if_ you account for a few key differences.
-
-***index.html***
-
-The JIT and AOT apps require their own `index.html` files because they setup and launch so differently.
-
-Here they are for comparison:
-
-<md-tab-group>
-
-  <md-tab label="aot/index.html (AOT)">
-    {@example 'toh-6/ts/aot/index.html'}
-  </md-tab>
-
-
-  <md-tab label="src/index.html (JIT)">
-    {@example 'toh-6/ts/src/index.html'}
-  </md-tab>
-
-
-</md-tab-group>
-
-The JIT version relies on `SystemJS` to load individual modules.
-Its scripts appear in its `index.html`.
-
-The AOT version loads the entire application in a single script, `aot/dist/build.js`.
-It does not need `SystemJS`, so that script is absent from its `index.html`
-
-***main.ts***
-
-JIT and AOT applications boot in much the same way but require different Angular libraries to do so.
-The key differences, covered in the [Bootstrap](#bootstrap) section above,
-are evident in these `main` files which can and should reside in the same folder:
-
-<md-tab-group>
-
-  <md-tab label="main-aot.ts (AOT)">
-    {@example 'toh-6/ts/src/main-aot.ts'}
-  </md-tab>
-
-
-  <md-tab label="main.ts (JIT)">
-    {@example 'toh-6/ts/src/main.ts'}
-  </md-tab>
-
-
-</md-tab-group>
-
-***TypeScript configuration***
-
-JIT-compiled applications transpile to `commonjs` modules.
-AOT-compiled applications transpile to _ES2015_/_ES6_ modules to facilitate Tree Shaking.
-AOT requires its own TypeScript configuration settings as well.
-
-You'll need separate TypeScript configuration files such as these:
-
-<md-tab-group>
-
-  <md-tab label="tsconfig-aot.json (AOT)">
-    {@example 'toh-6/ts/tsconfig-aot.json'}
-  </md-tab>
-
-
-  <md-tab label="src/tsconfig.json (JIT)">
-    {@example 'toh-6/ts/src/tsconfig.1.json'}
-  </md-tab>
-
-
-</md-tab-group>
-
-
-
-~~~ {.callout.is-helpful}
-
-
-<header>
-  @Types and node modules
-</header>
-
-In the file structure of _this particular sample project_,
-the `node_modules` folder happens to be two levels up from the project root.
-Therefore, `"typeRoots"` must be set to `"../../node_modules/@types/"`.
-
-In a more typical project, `node_modules` would be a sibling of `tsconfig-aot.json`
-and `"typeRoots"` would be set to `"node_modules/@types/"`.
-Edit your `tsconfig-aot.json` to fit your project's file structure.
-
-
-~~~
-
-### Tree Shaking
-
-Rollup does the Tree Shaking as before.
-
-
-{@example 'toh-6/ts/rollup-config.js'}
-
-### Running the application
-
-
-~~~ {.alert.is-important}
-
-The general audience instructions for running the AOT build of the Tour of Heroes app are not ready.
-
-The following instructions presuppose that you have cloned the
-<a href="https://github.com/angular/angular.io" target="_blank">angular.io</a>
-github repository and prepared it for development as explained in the repo's README.md.
-
-The _Tour of Heroes_ source code is in the `public/docs/_examples/toh-6/ts` folder.
-
-~~~
-
-Run the JIT-compiled app with `npm start` as for all other JIT examples.
-
-Compiling with AOT presupposes certain supporting files, most of them discussed above.
-<md-tab-group>
-
-  <md-tab label="src/index.html">
-    {@example 'toh-6/ts/src/index.html'}
-  </md-tab>
-
-
-  <md-tab label="copy-dist-files.js">
-    {@example 'toh-6/ts/copy-dist-files.js'}
-  </md-tab>
-
-
-  <md-tab label="rollup-config.js">
-    {@example 'toh-6/ts/rollup-config.js'}
-  </md-tab>
-
-
-  <md-tab label="tsconfig-aot.json">
-    {@example 'toh-6/ts/tsconfig-aot.json'}
-  </md-tab>
-
-
-</md-tab-group>
-
-Extend the `scripts` section of the `package.json` with these npm scripts:Copy the AOT distribution files into the `/aot` folder with the node script:
-<code-example language="none" class="code-shell">
-  node copy-dist-files
-</code-example>
-
-
-You won't do that again until there are updates to `zone.js` or the `core-js` shim for old browsers.Now AOT-compile the app and launch it with the `lite` server:
-<code-example language="none" class="code-shell">
-  npm run build:aot && npm run serve:aot  
-    
-</code-example>
-
-### Inspect the Bundle
-
-It's fascinating to see what the generated JavaScript bundle looks like after Rollup.
-The code is minified, so you won't learn much from inspecting the bundle directly.
-But the <a href="https://github.com/danvk/source-map-explorer/blob/master/README.md" target="_blank">source-map-explorer</a>
-tool can be quite revealing.
-
-Install it:
-<code-example language="none" class="code-shell">
-  npm install source-map-explorer --save-dev
-</code-example>
-
-Run the following command to generate the map.
-
-<code-example language="none" class="code-shell">
-  node_modules/.bin/source-map-explorer aot/dist/build.js  
-    
-</code-example>
-
-The `source-map-explorer` analyzes the source map generated with the bundle and draws a map of all dependencies,
-showing exactly which application and Angular modules and classes are included in the bundle.
-
-Here's the map for _Tour of Heroes_.

-
-`HeroChildComponent` has two ***input properties***, 
-typically adorned with [@Input decorations](../guide/template-syntax.html#inputs-outputs).
-
-
-{@example 'cb-component-communication/ts/src/app/hero-child.component.ts'}
-
-The second `@Input` aliases the child component property name `masterName` as `'master'`.
-
-The `HeroParentComponent` nests the child `HeroChildComponent` inside an `*ngFor` repeater, 
-binding its `master` string property to the child's `master` alias
-and each iteration's `hero` instance to the child's `hero` property.
-
-
-{@example 'cb-component-communication/ts/src/app/hero-parent.component.ts'}
-
-The running application displays three heroes:
-
-<figure class='image-display'>
-  <img src="assets/images/cookbooks/component-communication/parent-to-child.png" alt="Parent-to-child">  </img>
-</figure>
-
-### Test it
-
-E2E test that all children were instantiated and displayed as expected:
-
-
-{@example 'cb-component-communication/e2e-spec.ts' region='parent-to-child'}
-
-[Back to top](#top)
-
-<a id="parent-to-child-setter"></a>## Intercept input property changes with a setter
-
-Use an input property setter to intercept and act upon a value from the parent.
-
-The setter of the `name` input property in the child `NameChildComponent` 
-trims the whitespace from a name and replaces an empty value with default text. 
-
-
-{@example 'cb-component-communication/ts/src/app/name-child.component.ts'}
-
-Here's the `NameParentComponent` demonstrating name variations including a name with all spaces:
-
-
-{@example 'cb-component-communication/ts/src/app/name-parent.component.ts'}
-
-
-<figure class='image-display'>

-
-### Test it
-
-E2E tests of input property setter with empty and non-empty names:

-
-[Back to top](#top)
-
-<a id="parent-to-child-on-changes"></a>## Intercept input property changes with *ngOnChanges*
-
-Detect and act upon changes to input property values with the `ngOnChanges` method of the `OnChanges` lifecycle hook interface.
-May prefer this approach to the property setter when watching multiple, interacting input properties.
-
-Learn about `ngOnChanges` in the [LifeCycle Hooks](../guide/lifecycle-hooks.html) chapter.This `VersionChildComponent` detects changes to the `major` and `minor` input properties and composes a log message reporting these changes:
-
-
-{@example 'cb-component-communication/ts/src/app/version-child.component.ts'}
-
-The `VersionParentComponent` supplies the `minor` and `major` values and binds buttons to methods that change them.
-
-
-{@example 'cb-component-communication/ts/src/app/version-parent.component.ts'}
-
-Here's the output of a button-pushing sequence:

-
-### Test it
-
-Test that ***both*** input properties are set initially and that button clicks trigger 
-the expected `ngOnChanges` calls and values:
-
-
-{@example 'cb-component-communication/e2e-spec.ts' region='parent-to-child-onchanges'}
-
-[Back to top](#top)
-
-<a id="child-to-parent"></a>## Parent listens for child event
-
-The child component exposes an `EventEmitter` property with which it `emits`events when something happens. 
-The parent binds to that event property and reacts to those events.
-
-The child's `EventEmitter` property is an ***output property***, 
-  typically adorned with an [@Output decoration](../guide/template-syntax.html#inputs-outputs)
-  as seen in this `VoterComponent`:
-
-
-{@example 'cb-component-communication/ts/src/app/voter.component.ts'}
-
-Clicking a button triggers emission of a `true` or `false` (the boolean *payload*).
-
-The parent `VoteTakerComponent` binds an event handler (`onVoted`) that responds to the child event
-payload (`$event`) and updates a counter.
-
-
-{@example 'cb-component-communication/ts/src/app/votetaker.component.ts'}
-
-The framework passes the event argument &mdash; represented by `$event` &mdash; to the handler method, 
-and the method processes it:

-
-## Parent interacts with child via *local variable*
-
-A parent component cannot use data binding to read child properties
-or invoke child methods. We can do both 
-by creating a template reference variable for the child element
-and then reference that variable *within the parent template*
-as seen in the following example.
-
-<a id="countdown-timer-example"></a>
-We have a child `CountdownTimerComponent` that repeatedly counts down to zero and launches a rocket.
-It has `start` and `stop` methods that control the clock and it displays a
-countdown status message in its own template.
-
-{@example 'cb-component-communication/ts/src/app/countdown-timer.component.ts'}
-
-Let's see the `CountdownLocalVarParentComponent` that hosts the timer component.
-
-
-{@example 'cb-component-communication/ts/src/app/countdown-parent.component.ts' region='lv'}
-
-The parent component cannot data bind to the child's 
-`start` and `stop` methods nor to its `seconds` property.
-
-We can place a local variable (`#timer`) on the tag (`<countdown-timer>`) representing the child component.
-That gives us a reference to the child component itself and the ability to access
-*any of its properties or methods* from within the parent template.
-
-In this example, we wire parent buttons to the child's `start` and `stop` and
-use interpolation to display the child's `seconds` property.
-
-Here we see the parent and child working together.
-
-<figure class='image-display'>
-  <img src="assets/images/cookbooks/component-communication/countdown-timer-anim.gif" alt="countdown timer">  </img>
-</figure>
-
-
-
-{@a countdown-tests}
-### Test it
-
-Test that the seconds displayed in the parent template
-match the seconds displayed in the child's status message.
-Test also that clicking the *Stop* button pauses the countdown timer:
-
-
-{@example 'cb-component-communication/e2e-spec.ts' region='countdown-timer-tests'}
-
-[Back to top](#top)
-
-<a id="parent-to-view-child"></a>## Parent calls a *ViewChild*
-
-The *local variable* approach is simple and easy. But it is limited because 
-the parent-child wiring must be done entirely within the parent template.
-The parent component *itself* has no access to the child.
-
-We can't use the *local variable* technique if an instance of the parent component *class*
-must read or write child component values or must call child component methods.
-
-When the parent component *class* requires that kind of access, 
-we ***inject*** the child component into the parent as a *ViewChild*.
-
-We'll illustrate this technique with the same [Countdown Timer](#countdown-timer-example) example. 
-We won't change its appearance or behavior. 
-The child [CountdownTimerComponent](#countdown-timer-example) is the same as well.
-We are switching from the *local variable* to the *ViewChild* technique
-solely for the purpose of demonstration.Here is the parent, `CountdownViewChildParentComponent`:
-
-{@example 'cb-component-communication/ts/src/app/countdown-parent.component.ts' region='vc'}
-
-It takes a bit more work to get the child view into the parent component *class*.
- 
-We import references to the `ViewChild` decorator and the `AfterViewInit` lifecycle hook.
-
-We inject the child `CountdownTimerComponent` into the private `timerComponent` property
-via the `@ViewChild` property decoration.
-
-The `#timer` local variable is gone from the component metadata. 
-Instead we bind the buttons to the parent component's own `start` and `stop` methods and
-present the ticking seconds in an interpolation around the parent component's `seconds` method.
-
-These methods access the injected timer component directly.
-
-The `ngAfterViewInit` lifecycle hook is an important wrinkle.
-The timer component isn't available until *after* Angular displays the parent view.
-So we display `0` seconds initially.
-
-Then Angular calls the `ngAfterViewInit` lifecycle hook at which time it is *too late*
-to update the parent view's display of the countdown seconds.
-Angular's unidirectional data flow rule prevents us from updating the parent view's
-in the same cycle. We have to *wait one turn* before we can display the seconds.
-
-We use `setTimeout` to wait one tick and then revise the `seconds` method so 
-that it takes future values from the timer component.
-
-### Test it
-Use [the same countdown timer tests](#countdown-tests) as before.[Back to top](#top)
-
-<a id="bidirectional-service"></a>## Parent and children communicate via a service
-
-A parent component and its children share a service whose interface enables bi-directional communication
-*within the family*.
-
-The scope of the service instance is the parent component and its children. 
-Components outside this component subtree have no access to the service or their communications.
-
-This `MissionService` connects the `MissionControlComponent` to multiple `AstronautComponent` children.
-
-
-{@example 'cb-component-communication/ts/src/app/mission.service.ts'}
-
-The `MissionControlComponent` both provides the instance of the service that it shares with its children
-(through the `providers` metadata array) and injects that instance into itself through its constructor:
-
-
-{@example 'cb-component-communication/ts/src/app/missioncontrol.component.ts'}
-
-The `AstronautComponent` also injects the service in its constructor.
-Each `AstronautComponent` is a child of the `MissionControlComponent` and therefore receives its parent's service instance:
-
-
-{@example 'cb-component-communication/ts/src/app/astronaut.component.ts'}
-
-
-Notice that we capture the `subscription` and unsubscribe when the `AstronautComponent` is destroyed.
-This is a memory-leak guard step. There is no actual risk in this app because the
-lifetime of a `AstronautComponent` is the same as the lifetime of the app itself.
-That *would not* always be true in a more complex application.
-
-We do not add this guard to the `MissionControlComponent` because, as the parent,
-it controls the lifetime of the `MissionService`.The *History* log demonstrates that messages travel in both directions between
-the parent `MissionControlComponent` and the `AstronautComponent` children,
-facilitated by the service:
-
-<figure class='image-display'>

-Tests click buttons of both the parent `MissionControlComponent` and the `AstronautComponent` children
-and verify that the *History* meets expectations:

-Component-relative Paths
-
-@intro
-Use relative URLs for component templates and styles.
-
-@description
-## Write *Component-Relative* URLs to component templates and style files
-
-Our components often refer to external template and style files.
-We identify those files with a URL in the `templateUrl` and `styleUrls` properties of the `@Component` metadata
-as seen here:
-
-
-{@example 'cb-component-relative-paths/ts/src/app/some.component.ts' region='absolute-config'}
-
-By default, we *must* specify the full path back to the application root.
-We call this an ***absolute path*** because it is *absolute* with respect to the application root.
-
-There are two problems with an *absolute path*:
-
-1. We have to remember the full path back to the application root.
-
-1. We have to update the URL when we move the component around in the application files structure.
-
-It would be much easier to write and maintain our application components if we could specify template and style locations
-*relative* to their component class file.
-
-*We can!*
-
-
-~~~ {.alert.is-important}
-
-We can if we build our application as `commonjs` modules and load those modules
-with a suitable package loader such as `systemjs` or `webpack`.
-Learn why [below](#why-default).
-
-The Angular CLI uses these technologies and defaults to the
-*component-relative path* approach described here.
-CLI users can skip this chapter or read on to understand
-how it works.
-
-
-~~~
-
-
-## _Component-Relative_ Paths
-
-Our goal is to specify template and style URLs *relative* to their component class files, 
-hence the term ***component-relative path***.
-
-The key to success is following a convention that puts related component files in well-known locations.
-
-We recommend keeping component template and component-specific style files as *siblings* of their
-companion component class files. 
-Here we see the three files for `SomeComponent` sitting next to each other in the `app` folder. 
-
-<aio-filetree>
-
-  <aio-folder>
-    app
-    <aio-file>
-      some.component.css
-    </aio-file>
-
-
-    <aio-file>
-      some.component.html
-    </aio-file>
-
-
-    <aio-file>
-      some.component.ts
-    </aio-file>
-
-
-  </aio-folder>
-
-
-</aio-filetree>
-
-We'll have more files and folders &mdash; and greater folder depth &mdash; as our application grows.
-We'll be fine as long as the component files travel together as the inseparable siblings they are.
-
-### Set the *moduleId*
-
-Having adopted this file structure convention, we can specify locations of the template and style files
-relative to the component class file simply by setting the `moduleId` property of the `@Component` metadata like this
-
-{@example 'cb-component-relative-paths/ts/src/app/some.component.ts' region='module-id'}
-
-We strip the `src/app/` base path from the `templateUrl` and `styleUrls` and replace it with `./`. 
-The result looks like this:
-
-{@example 'cb-component-relative-paths/ts/src/app/some.component.ts' region='relative-config'}
-
-
-
-~~~ {.alert.is-helpful}
-
-Webpack users may prefer [an alternative approach](#webpack).

-
-## Appendix: why *component-relative* is not the default
-
-A *component-relative* path is obviously superior to an *absolute* path.
-Why did Angular default to the *absolute* path?
-Why do *we* have to set the `moduleId`? Why can't Angular set it?
-
-First, let's look at what happens if we use a relative path and omit the `moduleId`.
-
-`EXCEPTION: Failed to load some.component.html`
-
-Angular can't find the file so it throws an error.
-
-Why can't Angular calculate the template and style URLs from the component file's location? 
-
-Because the location of the component can't be determined without the developer's help.
-Angular apps can be loaded in many ways: from individual files, from SystemJS packages, or
-from CommonJS packages, to name a few. 
-We might generate modules in any of several formats. 
-We might not be writing modular code at all!
-
-With this diversity of packaging and module load strategies, 
-it's not possible for Angular to know with certainty where these files reside at runtime.
-
-The only location Angular can be sure of is the URL of the `index.html` home page, the application root.
-So by default it resolves template and style paths relative to the URL of `index.html`.
-That's why we previously wrote our file URLs with an `app/` base path prefix.
-
-But *if* we follow the recommended guidelines and we write modules in `commonjs` format
-and we use a module loader that *plays nice*,
-*then* we &mdash; the developers of the application &mdash;
-know that the semi-global `module.id` variable is available and contains
-the absolute URL of the component class module file.
-
-That knowledge enables us to tell Angular where the *component* file is
-by setting the `moduleId`:
-
-{@example 'cb-component-relative-paths/ts/src/app/some.component.ts' region='module-id'}
-
-
-
-{@a webpack}
-
-## Webpack: load templates and styles
-Webpack developers have an alternative to `moduleId`.
-
-They can load templates and styles at runtime by adding `./` at the beginning of the `template` and `styles` / `styleUrls`
-properties that reference *component-relative URLS.
-
-
-{@example 'webpack/ts/src/app/app.component.ts'}
-
-
-Webpack will do a `require` behind the scenes to load the templates and styles. Read more [here](../guide/webpack.html#highlights).

-
-<a id="app-wide-dependencies"></a>## Application-wide dependencies   
-Register providers for dependencies used throughout the application in the root application component, `AppComponent`.
-
-In the following example, we import and register several services 
-(the `LoggerService`, `UserContext`, and the `UserService`)
-in the `@Component` metadata `providers` array.
-
-
-{@example 'cb-dependency-injection/ts/src/app/app.component.ts' region='import-services'}
-
-All of these services are implemented as classes. 
-Service classes can act as their own providers which is why listing them in the `providers` array
-is all the registration we need.
-A *provider* is something that can create or deliver a service.
-Angular creates a service instance from a class provider by "new-ing" it.
-Learn more about providers [below](#providers).Now that we've registered these services, 
-Angular can inject them into the constructor of *any* component or service, *anywhere* in the application.
-
-{@example 'cb-dependency-injection/ts/src/app/hero-bios.component.ts' region='ctor'}
-
-
-
-{@example 'cb-dependency-injection/ts/src/app/user-context.service.ts' region='ctor'}
-
-<a id="external-module-configuration"></a>
-## External module configuration
-We often register providers in the `NgModule` rather than in the root application component.
-
-We do this when (a) we expect the service to be injectable everywhere
-or (b) we must configure another application global service _before it starts_.
-
-We see an example of the second case here, where we configure the Component Router with a non-default
-[location strategy](../guide/router.html#location-strategy) by listing its provider 
-in the `providers` list of the `AppModule`.
-
-
-{@example 'cb-dependency-injection/ts/src/app/app.module.ts' region='providers'}
-
-
-
-{@a injectable}
-
-
-{@a nested-dependencies}
-
-## *@Injectable* and nested service dependencies
-The consumer of an injected service does not know how to create that service.
-It shouldn't care.
-It's the dependency injection's job to create and cache that service.
-
-Sometimes a service depends on other services ... which may depend on yet other services.
-Resolving these nested dependencies in the correct order is also the framework's job.
-At each step, the consumer of dependencies simply declares what it requires in its constructor and the framework takes over.
-
-For example, we inject both the `LoggerService` and the `UserContext` in the `AppComponent`. 
-
-{@example 'cb-dependency-injection/ts/src/app/app.component.ts' region='ctor'}
-
-The `UserContext` in turn has dependencies on both the `LoggerService` (again) and 
-a `UserService` that gathers information about a particular user.
-
-
-{@example 'cb-dependency-injection/ts/src/app/user-context.service.ts' region='injectables'}
-
-When Angular creates an`AppComponent`, the dependency injection framework creates an instance of the `LoggerService` and 
-starts to create the `UserContextService`.
-The `UserContextService` needs the `LoggerService`, which the framework already has, and the `UserService`, which it has yet to create. 
-The `UserService` has no dependencies so the dependency injection framework can just `new` one into existence.
-
-The beauty of dependency injection is that the author of `AppComponent` didn't care about any of this. 
-The author simply declared what was needed in the constructor (`LoggerService` and `UserContextService`) and the framework did the rest.
-
-Once all the dependencies are in place, the `AppComponent` displays the user information:
- 
-<figure class='image-display'>
-  <img src="assets/images/cookbooks/dependency-injection/logged-in-user.png" alt="Logged In User">  </img>
-</figure>
-
-### *@Injectable()*
-Notice the `@Injectable()`decorator on the `UserContextService` class. 
-
-{@example 'cb-dependency-injection/ts/src/app/user-context.service.ts' region='injectable'}
-
-That decorator makes it possible for Angular to identify the types of its two dependencies, `LoggerService` and `UserService`.
-
-Technically, the `@Injectable()`decorator is only _required_ for a service class that has _its own dependencies_.
-The `LoggerService` doesn't depend on anything. The logger would work if we omitted `@Injectable()`
-and the generated code would be slightly smaller. 
-
-But the service would break the moment we gave it a dependency and we'd have to go back and
-and add `@Injectable()` to fix it. We add `@Injectable()` from the start for the sake of consistency and to avoid future pain.
-
-
-~~~ {.alert.is-helpful}
-
-Although we recommend applying `@Injectable` to all service classes, do not feel bound by it.
-Some developers prefer to add it only where needed and that's a reasonable policy too.
-
-
-~~~
-
-
-The `AppComponent` class had two dependencies as well but no `@Injectable()`.
-It didn't need `@Injectable()` because that component class has the `@Component` decorator.
-In Angular with TypeScript, a *single* decorator &mdash; *any* decorator &mdash; is sufficient to identify dependency types.
-
-<a id="service-scope"></a>
-## Limit service scope to a component subtree
-
-All injected service dependencies are singletons meaning that, 
-for a given dependency injector ("injector"), there is only one instance of service. 
-
-But an Angular application has multiple dependency injectors, arranged in a tree hierarchy that parallels the component tree.
-So a particular service can be *provided* (and created) at any component level and multiple times
-if provided in multiple components.
-
-By default, a service dependency provided in one component is visible to all of its child components and 
-Angular injects the same service instance into all child components that ask for that service.
-
-Accordingly, dependencies provided in the root `AppComponent` can be injected into *any* component *anywhere* in the application.
-
-That isn't always desirable. 
-Sometimes we want to restrict service availability to a particular region of the application.
-
-We can limit the scope of an injected service to a *branch* of the application hierarchy
-by providing that service *at the sub-root component for that branch*.
-Here we provide the `HeroService` to the `HeroesBaseComponent` by listing it in the `providers` array:
-
-{@example 'cb-dependency-injection/ts/src/app/sorted-heroes.component.ts' region='injection'}
-
-When Angular creates the `HeroesBaseComponent`, it also creates a new instance of `HeroService` 
-that is visible only to the component and its children (if any).
-
-We could also provide the `HeroService` to a *different* component elsewhere in the application. 
-That would result in a *different* instance of the service, living in a *different* injector.
-We examples of such scoped `HeroService` singletons appear throughout the accompanying sample code, 
-including the `HeroBiosComponent`, `HeroOfTheMonthComponent`, and `HeroesBaseComponent`. 
-Each of these components has its own `HeroService` instance managing its own independent collection of heroes.
-
-
-
-~~~ {.alert.is-helpful}
-
-### Take a break!
-This much Dependency Injection knowledge may be all that many Angular developers
-ever need to build their applications. It doesn't always have to be more complicated.
-
-
-~~~
-
-<a id="multiple-service-instances"></a>
-## Multiple service instances (sandboxing)
-
-Sometimes we want multiple instances of a service at *the same level of the component hierarchy*.
-
-A good example is a service that holds state for its companion component instance. 
-We need a separate instance of the service for each component.
-Each service has its own work-state, isolated from the service-and-state of a different component.
-We call this *sandboxing* because each service and component instance has its own sandbox to play in.
-
-<a id="hero-bios-component"></a>
-Imagine a `HeroBiosComponent` that presents three instances of the `HeroBioComponent`. 
-
-{@example 'cb-dependency-injection/ts/src/app/hero-bios.component.ts' region='simple'}
-
-Each `HeroBioComponent` can edit a single hero's biography. 
-A `HeroBioComponent` relies on a `HeroCacheService` to fetch, cache, and perform other persistence operations on that hero.
-
-{@example 'cb-dependency-injection/ts/src/app/hero-cache.service.ts' region='service'}
-
-Clearly the three instances of the `HeroBioComponent` can't share the same `HeroCacheService`. 
-They'd be competing with each other to determine which hero to cache.
-
-Each `HeroBioComponent` gets its *own* `HeroCacheService` instance 
-by listing the `HeroCacheService` in its metadata `providers` array.
-
-{@example 'cb-dependency-injection/ts/src/app/hero-bio.component.ts' region='component'}
-
-The parent `HeroBiosComponent` binds a value to the `heroId`.
-The `ngOnInit` pass that `id` to the service which fetches and caches the hero. 
-The getter for the `hero` property pulls the cached hero from the service.
-And the template displays this data-bound property.
-
-Find this example in <live-example name="cb-dependency-injection">live code</live-example>
-and confirm that the three `HeroBioComponent` instances have their own cached hero data.

-</figure>
-
-
-
-{@a optional}
-
-
-{@a qualify-dependency-lookup}
-
-## Qualify dependency lookup with *@Optional* and *@Host*
-We learned that dependencies can be registered at any level in the component hierarchy. 
-
-When a component requests a dependency, Angular starts with that component's injector and walks up the injector tree 
-until it finds the first suitable provider.  Angular throws an error if it can't find the dependency during that walk. 
- 
-We *want* this behavior most of the time. 
-But sometimes we need to limit the search and/or accommodate a missing dependency.
-We can modify Angular's search behavior with the `@Host` and `@Optional` qualifying decorators,
-used individually or together.
-
-The `@Optional` decorator tells Angular to continue when it can't find the dependency. 
-Angular sets the injection parameter to `null` instead.
-
-The `@Host` decorator stops the upward search at the *host component*. 
-
-The host component is typically the component requesting the dependency. 
-But when this component is projected into a *parent* component, that parent component becomes the host.
-We look at this second, more interesting case in our next example.
-
-### Demonstration
-The `HeroBiosAndContactsComponent` is a revision of the `HeroBiosComponent` that we looked at [above](#hero-bios-component).
-
-{@example 'cb-dependency-injection/ts/src/app/hero-bios.component.ts' region='hero-bios-and-contacts'}
-
-Focus on the template:
-
-{@example 'cb-dependency-injection/ts/src/app/hero-bios.component.ts' region='template'}
-
-We've inserted a `<hero-contact>` element between the `<hero-bio>` tags.
-Angular *projects* (*transcludes*) the corresponding `HeroContactComponent` into the `HeroBioComponent` view, 
-placing it in the `<ng-content>` slot of the `HeroBioComponent` template:
-
-{@example 'cb-dependency-injection/ts/src/app/hero-bio.component.ts' region='template'}
-
-It looks like this, with the hero's telephone number from `HeroContactComponent` projected above the hero description:
-<figure class='image-display'>
-  <img src="assets/images/cookbooks/dependency-injection/hero-bio-and-content.png" alt="bio and contact">       </img>
-</figure>
-
-Here's the `HeroContactComponent` which demonstrates the qualifying decorators that we're talking about in this section:
-
-{@example 'cb-dependency-injection/ts/src/app/hero-contact.component.ts' region='component'}
-
-Focus on the constructor parameters
-
-{@example 'cb-dependency-injection/ts/src/app/hero-contact.component.ts' region='ctor-params'}
-
-The `@Host()` function decorating the  `heroCache` property ensures that 
-we get a reference to the cache service from the parent `HeroBioComponent`.
-Angular throws if the parent lacks that service, even if a component higher in the component tree happens to have that service.
-
-A second `@Host()` function decorates the `loggerService` property.
-We know the only `LoggerService` instance in the app is provided at the `AppComponent` level.
-The host `HeroBioComponent` doesn't have its own `LoggerService` provider.
-
-Angular would throw an error if we hadn't also decorated the property with the `@Optional()` function.
-Thanks to `@Optional()`, Angular sets the `loggerService` to null and the rest of the component adapts.
-
-We'll come back to the `elementRef` property shortly.Here's the `HeroBiosAndContactsComponent` in action.
-<figure class='image-display'>
-  <img src="assets/images/cookbooks/dependency-injection/hero-bios-and-contacts.png" alt="Bios with contact into">  </img>
-</figure>
-
-If we comment out the `@Host()` decorator, Angular now walks up the injector ancestor tree 
-until it finds the logger at the `AppComponent` level. The logger logic kicks in and the hero display updates
-with the gratuitous "!!!", indicating that the logger was found.
-<figure class='image-display'>
-  <img src="assets/images/cookbooks/dependency-injection/hero-bio-contact-no-host.png" alt="Without @Host">     </img>
-</figure>
-
-On the other hand, if we restore the `@Host()` decorator and comment out `@Optional`, 
-the application fails for lack of the required logger at the host component level.

-<a id="component-element"></a>## Inject the component's element
-
-On occasion we might need to access a component's corresponding DOM element. 
-Although we strive to avoid it, many visual effects and 3rd party tools (such as jQuery)
-require DOM access. 
-
-To illustrate, we've written a simplified version of the `HighlightDirective` from 
-the [Attribute Directives](../guide/attribute-directives.html) chapter.
-
-{@example 'cb-dependency-injection/ts/src/app/highlight.directive.ts'}
-
-The directive sets the background to a highlight color when the user mouses over the
-DOM element to which it is applied.
-
-Angular set the constructor's `el` parameter to the injected `ElementRef` which is 
-a wrapper around that DOM element. 
-Its `nativeElement` property exposes the DOM element for the directive to manipulate.
-
-The sample code applies the directive's `myHighlight` attribute to two `<div>` tags, 
-first without a value (yielding the default color) and then with an assigned color value.
-
-{@example 'cb-dependency-injection/ts/src/app/app.component.html' region='highlight'}
-
-The following image shows the effect of mousing over the `<hero-bios-and-contacts>` tag.

-
-<a id="providers"></a>
-## Define dependencies with providers
-
-In this section we learn to write providers that deliver dependent services.
-
-### Background
-We get a service from a dependency injector by giving it a ***token***. 
-
-We usually let Angular handle this transaction for us by specifying a constructor parameter and its type.
-The parameter type serves as the injector lookup *token*. 
-Angular passes this token to the injector and assigns the result to the parameter.
-Here's a typical example:
-
-
-{@example 'cb-dependency-injection/ts/src/app/hero-bios.component.ts' region='ctor'}
-
-Angular asks the injector for the service associated with the `LoggerService` and
-and assigns the returned value to the `logger` parameter.
-
-Where did the injector get that value?
-It may already have that value in its internal container. 
-If it doesn't, it may be able to make one with the help of a ***provider***.
-A *provider* is a recipe for delivering a service associated with a *token*.
-If the injector doesn't have a provider for the requested *token*, it delegates the request 
-to its parent injector, where the process repeats until there are no more injectors. 
-If the search is futile, the injector throws an error ... unless the request was [optional](#optional).
-
-Let's return our attention to providers themselves.A new injector has no providers.
-Angular initializes the injectors it creates with some providers it cares about.
-We have to register our _own_ application providers manually, 
-usually in the `providers` array of the `Component` or `Directive` metadata:
-
-{@example 'cb-dependency-injection/ts/src/app/app.component.ts' region='providers'}
-
-### Defining providers
-
-The simple class provider is the most typical by far.
-We mention the class in the `providers` array and we're done.
-
-{@example 'cb-dependency-injection/ts/src/app/hero-bios.component.ts' region='class-provider'}
-
-It's that simple because the most common injected service is an instance of a class.
-But not every dependency can be satisfied by creating a new instance of a class.
-We need other ways to deliver dependency values and that means we need other ways to specify a provider.
-
-The `HeroOfTheMonthComponent` example demonstrates many of the alternatives and why we need them. 
-
-<figure class='image-display'>
-  <img src="assets/images/cookbooks/dependency-injection/hero-of-month.png" alt="Hero of the month" width="300px">  </img>
-</figure>
-
-It's visually simple: a few properties and the output of a logger. The code behind it gives us plenty to talk about.
-
-{@example 'cb-dependency-injection/ts/src/app/hero-of-the-month.component.ts' region='hero-of-the-month'}
-
-
-
-
-{@a provide}
-#### The *provide* object literal
-
-The `provide` object literal takes a *token* and a *definition object*.
-The *token* is usually a class but [it doesn't have to be](#tokens).
-
-The *definition* object has one main property, (e.g. `useValue`) that indicates how the provider 
-should create or return the provided value.
-
-
-
-{@a usevalue}
-#### useValue - the *value provider*
-
-Set the `useValue` property to a ***fixed value*** that the provider can return as the dependency object.
-
-Use this technique to provide *runtime configuration constants* such as web-site base addresses and feature flags.
-We often use a *value provider* in a unit test to replace a production service with a fake or mock.
-
-The `HeroOfTheMonthComponent` example has two *value providers*.
-The first provides an instance of the `Hero` class; 
-the second specifies a literal string resource:
-
-{@example 'cb-dependency-injection/ts/src/app/hero-of-the-month.component.ts' region='use-value'}
-
-The `Hero` provider token is a class which makes sense because the value is a `Hero`
-and the consumer of the injected hero would want the type information.
-
-The `TITLE` provider token is *not a class*.
-It's a special kind of provider lookup key called an [OpaqueToken](#opaquetoken).
-We often use an `OpaqueToken` when the dependency is a simple value like a string, a number, or a function.
-
-The value of a *value provider* must be defined *now*. We can't create the value later. 
-Obviously the title string literal is immediately available. 
-The `someHero` variable in this example was set earlier in the file:
-
-{@example 'cb-dependency-injection/ts/src/app/hero-of-the-month.component.ts' region='some-hero'}
-
-The other providers create their values *lazily* when they're needed for injection.
-
-
-
-{@a useclass}
-#### useClass - the *class provider*
-
-The `useClass` provider creates and returns new instance of the specified class.
-
-Use this technique to ***substitute an alternative implementation*** for a common or default class.
-The alternative could implement a different strategy, extend the default class,
-or fake the behavior of the real class in a test case.
-
-We see two examples in the `HeroOfTheMonthComponent`:
-
-{@example 'cb-dependency-injection/ts/src/app/hero-of-the-month.component.ts' region='use-class'}
-
-The first provider is the *de-sugared*, expanded form of the most typical case in which the
-class to be created (`HeroService`) is also the provider's injection token. 
-We wrote it in this long form to de-mystify the preferred short form.
-
-The second provider substitutes the `DateLoggerService` for the `LoggerService`.
-The `LoggerService` is already registered at the `AppComponent` level.
-When _this component_ requests the `LoggerService`, it receives the `DateLoggerService` instead.
-This component and its tree of child components receive the `DateLoggerService` instance.
-Components outside the tree continue to receive the original `LoggerService` instance.The `DateLoggerService` inherits from `LoggerService`; it appends the current date/time to each message:  
-
-{@example 'cb-dependency-injection/ts/src/app/date-logger.service.ts' region='date-logger-service'}
-
-
-
-
-{@a useexisting}
-#### useExisting - the *alias provider*
-
-The `useExisting` provider maps one token to another. 
-In effect, the first token is an ***alias*** for the service associated with second token,
-creating ***two ways to access the same service object***.
-
-{@example 'cb-dependency-injection/ts/src/app/hero-of-the-month.component.ts' region='use-existing'}
-
-Narrowing an API through an aliasing interface is _one_ important use case for this technique.
-We're aliasing for that very purpose here.
-Imagine that the `LoggerService` had a large API (it's actually only three methods and a property).
-We want to shrink that API surface to just the two members exposed by the `MinimalLogger` [*class-interface*](#class-interface):
-
-
-{@example 'cb-dependency-injection/ts/src/app/date-logger.service.ts' region='minimal-logger'}
-
-The constructor's `logger` parameter is typed as `MinimalLogger` so only its two members are visible in TypeScript:
-<figure class='image-display'>
-  <img src="assets/images/cookbooks/dependency-injection/minimal-logger-intellisense.png" alt="MinimalLogger restricted API">  </img>
-</figure>
-
-Angular actually sets the `logger` parameter to the injector's full version of the `LoggerService` 
-which happens to be the `DateLoggerService` thanks to the override provider registered previously via `useClass`.
-The following image, which displays the logging date, confirms the point:
-<figure class='image-display'>
-  <img src="assets/images/cookbooks/dependency-injection/date-logger-entry.png" alt="DateLoggerService entry" width="300px">  </img>
-</figure>
-
-
-
-
-{@a usefactory}
-#### useFactory - the *factory provider*
-
-The `useFactory` provider creates a dependency object by calling a factory function
-as seen in this example.
-
-{@example 'cb-dependency-injection/ts/src/app/hero-of-the-month.component.ts' region='use-factory'}
-
-Use this technique to ***create a dependency object*** 
-with a factory function whose inputs are some ***combination of injected services and local state***.
-
-The *dependency object* doesn't have to be a class instance. It could be anything.
-In this example, the *dependency object* is a string of the names of the runners-up
-to the "Hero of the Month" contest.
-
-The local state is the number `2`, the number of runners-up this component should show.
-We execute `runnersUpFactory` immediately with `2`. 
-
-The `runnersUpFactory` itself isn't the provider factory function.
-The true provider factory function is the function that `runnersUpFactory` returns.
-
-
-{@example 'cb-dependency-injection/ts/src/app/runners-up.ts' region='factory-synopsis'}
-
-That returned function takes a winning `Hero` and a `HeroService` as arguments.
-
-Angular supplies these arguments from injected values identified by 
-the two *tokens* in the `deps` array. 
-The two `deps` values are *tokens* that the injector uses
-to provide these factory function dependencies.
-
-After some undisclosed work, the function returns the string of names 
-and Angular injects it into the `runnersUp` parameter of the `HeroOfTheMonthComponent`.
-
-The function retrieves candidate heroes from the `HeroService`, 
-takes `2` of them to be the runners-up, and returns their concatenated names.
-Look at the <live-example name="cb-dependency-injection"></live-example>
-for the full source code.
-
-
-{@a tokens}
-
-## Provider token alternatives: the *class-interface* and *OpaqueToken*
-
-Angular dependency injection is easiest when the provider *token* is a class
-that is also the type of the returned dependency object (what we usually call the *service*).
-
-But the token doesn't have to be a class and even when it is a class,
-it doesn't have to be the same type as the returned object.
-That's the subject of our next section. 
-
-<a id="class-interface"></a>
-### class-interface
-In the previous *Hero of the Month* example, we used the `MinimalLogger` class
-as the token for a provider of a `LoggerService`.
-
-{@example 'cb-dependency-injection/ts/src/app/hero-of-the-month.component.ts' region='use-existing'}
-
-The `MinimalLogger` is an abstract class. 
-
-{@example 'cb-dependency-injection/ts/src/app/date-logger.service.ts' region='minimal-logger'}
-
-We usually inherit from an abstract class.
-But `LoggerService` doesn't inherit from `MinimalLogger`. *No class* inherits from it.
-Instead, we use it like an interface.
-
-Look again at the declaration for `DateLoggerService`
-
-{@example 'cb-dependency-injection/ts/src/app/date-logger.service.ts' region='date-logger-service-signature'}
-
-`DateLoggerService` inherits (extends) from `LoggerService`, not `MinimalLogger`.
-The `DateLoggerService` *implements* `MinimalLogger` as if `MinimalLogger` were an *interface*.
-
-We call a class used in this way a ***class-interface***.
-The key benefit of a *class-interface* is that we can get the strong-typing of an interface
-and we can ***use it as a provider token*** in the same manner as a normal class.
-
-A ***class-interface*** should define *only* the members that its consumers are allowed to call.
-Such a narrowing interface helps decouple the concrete class from its consumers.
-The `MinimalLogger` defines just two of the `LoggerClass` members.
-
-#### Why *MinimalLogger* is a class and not an interface
-We can't use an interface as a provider token because 
-interfaces are not JavaScript objects. 
-They exist only in the TypeScript design space. 
-They disappear after the code is transpiled to JavaScript.
-
-A provider token must be a real JavaScript object of some kind: 
-a function, an object, a string ... a class.
-
-Using a class as an interface gives us the characteristics of an interface in a JavaScript object.
-
-The minimize memory cost, the class should have *no implementation*. 
-The `MinimalLogger` transpiles to this unoptimized, pre-minified JavaScript:
-
-{@example 'cb-dependency-injection/ts/src/app/date-logger.service.ts' region='minimal-logger-transpiled'}
-
-It never grows larger no matter how many members we add *as long as they are typed but not implemented*.
-
-
-{@a opaque-token}
-### OpaqueToken
-
-Dependency objects can be simple values like dates, numbers and strings or 
-shapeless objects like arrays and functions.
-
-Such objects don't have application interfaces and therefore aren't well represented by a class.
-They're better represented by a token that is both unique and symbolic, 
-a JavaScript object that has a friendly name but won't conflict with 
-another token that happens to have the same name.
-
-The `OpaqueToken` has these characteristics.
-We encountered them twice in the *Hero of the Month* example, 
-in the *title* value provider and in the *runnersUp* factory provider.
-
-{@example 'cb-dependency-injection/ts/src/app/hero-of-the-month.component.ts' region='provide-opaque-token'}
-
-We created the `TITLE` token like this:
-
-{@example 'cb-dependency-injection/ts/src/app/hero-of-the-month.component.ts' region='opaque-token'}
-
-
-
-{@a di-inheritance}
-
-## Inject into a derived class
-We must take care when writing a component that inherits from another component.
-If the base component has injected dependencies, 
-we must re-provide and re-inject them in the derived class
-and then pass them down to the base class through the constructor.
-
-In this contrived example, `SortedHeroesComponent` inherits from `HeroesBaseComponent` 
-to display a *sorted* list of heroes.
-
-<figure class='image-display'>
-  <img src="assets/images/cookbooks/dependency-injection/sorted-heroes.png" alt="Sorted Heroes">  </img>
-</figure>
-
-The `HeroesBaseComponent` could stand on its own.
-It demands its own instance of the `HeroService` to get heroes
-and displays them in the order they arrive from the database.
-
-
-{@example 'cb-dependency-injection/ts/src/app/sorted-heroes.component.ts' region='heroes-base'}
-
-
-We strongly prefer simple constructors. They should do little more than initialize variables.
-This rule makes the component safe to construct under test without fear that it will do something dramatic like talk to the server.
-That's why we call the `HeroService` from within the `ngOnInit` rather than the constructor.
-
-We explain the mysterious `afterGetHeroes` below.Users want to see the heroes in alphabetical order.
-Rather than modify the original component, we sub-class it and create a
-`SortedHeroesComponent` that sorts the heroes before presenting them.
-The `SortedHeroesComponent` lets the base class fetch the heroes.
-(we said it was contrived).
-
-Unfortunately, Angular cannot inject the `HeroService` directly into the base class.
-We must provide the `HeroService` again for *this* component, 
-then pass it down to the base class inside the constructor.
-  
-
-{@example 'cb-dependency-injection/ts/src/app/sorted-heroes.component.ts' region='sorted-heroes'}
-
-Now take note of the `afterGetHeroes` method. 
-Our first instinct was to create an `ngOnInit` method in `SortedHeroesComponent` and do the sorting there.
-But Angular calls the *derived* class's `ngOnInit` *before* calling the base class's `ngOnInit` 
-so we'd be sorting the heroes array *before they arrived*. That produces a nasty error.
-
-Overriding the base class's `afterGetHeroes` method solves the problem
-
-These complications argue for *avoiding component inheritance*. 
-
-
-{@a find-parent}
-
-## Find a parent component by injection
-
-Application components often need to share information.
-We prefer the more loosely coupled techniques such as data binding and service sharing.
-But sometimes it makes sense for one component to have a direct reference to another component
-perhaps to access values or call methods on that component.
- 
-Obtaining a component reference is a bit tricky in Angular.
-Although an Angular application is a tree of components,
-there is no public API for inspecting and traversing that tree. 
-
-There is an API for acquiring a child reference
-(checkout `Query`, `QueryList`, `ViewChildren`, and `ContentChildren`).
-
-There is no public API for acquiring a parent reference.
-But because every component instance is added to an injector's container,
-we can use Angular dependency injection to reach a parent component.
-
-This section describes some techniques for doing that.
-
-<a id="known-parent"></a>
-### Find a parent component of known type
-
-We use standard class injection to acquire a parent component whose type we know.
-
-In the following example, the parent `AlexComponent` has several children including a `CathyComponent`:
-
-{@a alex}
-
-
-{@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='alex-1'}
-
-*Cathy* reports whether or not she has access to *Alex*
-after injecting an `AlexComponent` into her constructor:
-
-{@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='cathy'}
-
-We added the [@Optional](#optional) qualifier for safety but
-the <live-example name="cb-dependency-injection"></live-example>
-confirms that the `alex` parameter is set.
-
-<a id="base-parent"></a>
-### Cannot find a parent by its base class
-
-What if we do *not* know the concrete parent component class?
-
-A re-usable component might be a child of multiple components.
-Imagine a component for rendering breaking news about a financial instrument.
-For sound (cough) business reasons, this news component makes frequent calls 
-directly into its parent instrument as changing market data stream by.
-
-The app probably defines more than a dozen financial instrument components.
-If we're lucky, they all implement the same base class
-whose API our `NewsComponent` understands.
-
-Looking for components that implement an interface would be better.
-That's not possible because TypeScript interfaces disappear from the transpiled JavaScript
-which doesn't support interfaces. There's no artifact we could look for.We're not claiming this is good design. 
-We are asking *can a component inject its parent via the parent's base class*?
-
-The sample's `CraigComponent` explores this question. [Looking back](#alex) 
-we see that the `Alex` component *extends* (*inherits*) from a class named `Base`.
-
-{@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='alex-class-signature'}
-
-The `CraigComponent` tries to inject `Base` into its `alex` constructor parameter and reports if it succeeded.
-
-{@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='craig'}
-
-Unfortunately, this does not work. 
-The <live-example name="cb-dependency-injection"></live-example>
-confirms that the `alex` parameter is null.
-*We cannot inject a parent by its base class.*
-
-<a id="class-interface-parent"></a>
-### Find a parent by its class-interface
-
-We can find a parent component with a [class-interface](#class-interface).
-
-The parent must cooperate by providing an *alias* to itself in the name of a *class-interface* token. 
-
-Recall that Angular always adds a component instance to its own injector; 
-that's why we could inject *Alex* into *Cathy* [earlier](#known-parent).
-
-We write an [*alias provider*](#useexisting) &mdash; a `provide` object literal with a `useExisting` definition &mdash;
-that creates an *alternative* way to inject the same component instance
-and add that provider to the `providers` array of the `@Component` metadata for the `AlexComponent`:
-
-{@a alex-providers}
-
-
-{@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='alex-providers'}
-
-[Parent](#parent-token) is the provider's *class-interface* token. 
-The [*forwardRef*](#forwardref) breaks the circular reference we just created by having the `AlexComponent` refer to itself.
-
-*Carol*, the third of *Alex*'s child components, injects the parent into its `parent` parameter, the same way we've done it before:
-
-{@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='carol-class'}
-
-Here's *Alex* and family in action:
-<figure class='image-display'>
-  <img src="assets/images/cookbooks/dependency-injection/alex.png" alt="Alex in action">  </img>
-</figure>
-
-
-
-{@a parent-tree}
-### Find the parent in a tree of parents
-
-Imagine one branch of a component hierarchy: *Alice* -> *Barry* -> *Carol*. 
-Both *Alice* and *Barry* implement the `Parent` *class-interface*.
-
-*Barry* is the problem. He needs to reach his parent, *Alice*, and also be a parent to *Carol*.
-That means he must both *inject* the `Parent` *class-interface* to get *Alice* and
-*provide* a `Parent` to satisfy *Carol*.
-
-Here's *Barry*:
-
-{@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='barry'}
-
-*Barry*'s `providers` array looks just like [*Alex*'s](#alex-providers).
-If we're going to keep writing [*alias providers*](#useexisting) like this we should create a [helper function](#provideparent).
-
-For now, focus on *Barry*'s constructor:
-<md-tab-group>
-
-  <md-tab label="Barry's constructor">
-    {@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='barry-ctor'}
-  </md-tab>
-
-
-  <md-tab label="Carol's constructor">
-    {@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='carol-ctor'}
-  </md-tab>
-
-
-</md-tab-group>
-
-It's identical to *Carol*'s constructor except for the additional `@SkipSelf` decorator.
-
-`@SkipSelf` is essential for two reasons:
- 
-1. It tells the injector to start its search for a `Parent` dependency in a component *above* itself,
-which *is* what parent means.
-
-2. Angular throws a cyclic dependency error if we omit the `@SkipSelf` decorator.
-
-  `Cannot instantiate cyclic dependency! (BethComponent -> Parent -> BethComponent)`
-
-Here's *Alice*, *Barry* and family in action:
-
-<figure class='image-display'>
-  <img src="assets/images/cookbooks/dependency-injection/alice.png" alt="Alice in action">  </img>
-</figure>
-
-
-
-{@a parent-token}
-### The *Parent* class-interface
-We [learned earlier](#class-interface) that a *class-interface* is an abstract class used as an interface rather than as a base class.
-
-Our example defines a `Parent` *class-interface* .
-
-{@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='parent'}
-
-The `Parent` *class-interface* defines a `name` property with a type declaration but *no implementation*., 
-The `name` property is the only member of a parent component that a child component can call.
-Such a narrowing interface helps decouple the child component class from its parent components.
-
-A component that could serve as a parent *should* implement the *class-interface* as the `AliceComponent` does:
-
-{@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='alice-class-signature'}
-
-Doing so adds clarity to the code.  But it's not technically necessary. 
-Although the `AlexComponent` has a `name` property (as required by its `Base` class) 
-its class signature doesn't mention `Parent`:
-
-{@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='alex-class-signature'}
-
-
-The `AlexComponent` *should* implement `Parent` as a matter of proper style. 
-It doesn't in this example *only* to demonstrate that the code will compile and run without the interface 
-
-
-{@a provideparent}
-### A *provideParent* helper function
-
-Writing variations of the same parent *alias provider* gets old quickly, 
-especially this awful mouthful with a [*forwardRef*](#forwardref):
-
-{@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='alex-providers'}
-
-We can extract that logic into a helper function like this:
-
-{@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='provide-the-parent'}
-
-Now we can add a simpler, more meaningful parent provider to our components:
-
-{@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='alice-providers'}
-
-We can do better. The current version of the helper function can only alias the `Parent` *class-interface*.
-Our application might have a variety of parent types, each with its own *class-interface* token.
-
-Here's a revised version that defaults to `parent` but also accepts an optional second parameter for a different parent *class-interface*.
-
-{@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='provide-parent'}
-
-And here's how we could use it with a different parent type:
-
-{@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='beth-providers'}
-
-

-## Break circularities with a forward class reference (*forwardRef*)
-
-The order of class declaration matters in TypeScript.
-We can't refer directly to a class until it's been defined.
-
-This isn't usually a problem, especially if we adhere to the recommended *one class per file* rule.
-But sometimes circular references are unavoidable. 
-We're in a bind when class 'A refers to class 'B' and 'B' refers to 'A'.
-One of them has to be defined first. 
-
-The Angular `forwardRef` function creates an *indirect* reference that Angular can resolve later.
-
-The *Parent Finder* sample is full of circular class references that are impossible to break.
-We face this dilemma when a class makes *a reference to itself*
-as does the `AlexComponent` in its `providers` array. 
-The `providers` array is a property of the `@Component` decorator function which must
-appear *above* the class definition.
-
-We break the circularity with `forwardRef`:

-{@example 'cb-dependency-injection/ts/src/app/parent-finder.component.ts' region='alex-providers'}

-Dynamic Component Loader

-@intro
-Load components dynamically
-
-@description
-Component templates are not always fixed. An application may need to load new components at runtime.
-
-In this cookbook we show how to use `ComponentFactoryResolver` to add components dynamically.

-
-<a id="dynamic-loading"></a>## Dynamic Component Loading      
-
-The following example shows how to build a dynamic ad banner. 
-
-The hero agency is planning an ad campaign with several different ads cycling through the banner.
-
-New ad components are added frequently by several different teams. This makes it impractical to use a template with a static component structure. 
-
-Instead we need a way to load a new component without a fixed reference to the component in the ad banner's template.
-
-Angular comes with its own API for loading components dynamically. In the following sections you will learn how to use it.
-
-
-<a id="where-to-load"></a>## Where to load the component
-
-Before components can be added we have to define an anchor point to mark where components can be inserted dynamically.
-
-The ad banner uses a helper directive called `AdDirective` to mark valid insertion points in the template.
-
-
-{@example 'cb-dynamic-component-loader/ts/src/app/ad.directive.ts'}
-
-`AdDirective` injects `ViewContainerRef` to gain access to the view container of the element that will become the host of the dynamically added component.
- 
-<a id="loading-components"></a>## Loading components
-
-The next step is to implement the ad banner. Most of the implementation is in `AdBannerComponent`.
-
-We start by adding a `template` element with the `AdDirective` directive applied.
-
-<md-tab-group>
-
-  <md-tab label="ad-banner.component.ts">
-    {@example 'cb-dynamic-component-loader/ts/src/app/ad-banner.component.ts'}
-  </md-tab>
-
-
-  <md-tab label="ad.service.ts">
-    {@example 'cb-dynamic-component-loader/ts/src/app/ad.service.ts'}
-  </md-tab>
-
-
-  <md-tab label="ad-item.ts">
-    {@example 'cb-dynamic-component-loader/ts/src/app/ad-item.ts'}
-  </md-tab>
-
-
-  <md-tab label="app.module.ts">
-    {@example 'cb-dynamic-component-loader/ts/src/app/app.module.ts'}
-  </md-tab>
-
-
-  <md-tab label="app.component">
-    {@example 'cb-dynamic-component-loader/ts/src/app/app.component.ts'}
-  </md-tab>
-
-
-</md-tab-group>
-
-The `template` element decorated with the `ad-host` directive marks where dynamically loaded components will be added.
-
-Using a `template` element is recommended since it doesn't render any additional output.
-
-
-{@example 'cb-dynamic-component-loader/ts/src/app/ad-banner.component.ts' region='ad-host'}
-
-### Resolving Components
-
-`AdBanner` takes an array of `AdItem` objects as input. `AdItem` objects specify the type of component to load and any data to bind to the component.
-
-The ad components making up the ad campaign are returned from `AdService`.
-
-Passing an array of components to `AdBannerComponent` allows for a dynamic list of ads without static elements in the template. 
-
-`AdBannerComponent` cycles through the array of `AdItems` and loads the corresponding components on an interval. Every 3 seconds a new component is loaded.
-
-`ComponentFactoryResolver` is used to resolve a `ComponentFactory` for each specific component. The component factory is need to create an instance of the component.
-
-`ComponentFactories` are generated by the Angular compiler. 
-
-Generally the compiler will generate a component factory for any component referenced in a template.
-
-With dynamically loaded components there are no selector references in the templates since components are loaded at runtime. In order to ensure that the compiler will still generate a factory, dynamically loaded components have to be added to their `NgModule`'s `entryComponents` array.   
-
-
-{@example 'cb-dynamic-component-loader/ts/src/app/app.module.ts' region='entry-components'}
-
-Components are added to the template by calling `createComponent` on the `ViewContainerRef` reference. 
-
-`createComponent` returns a reference to the loaded component. The component reference can be used to pass input data or call methods to interact with the component.
-
-In the Ad banner, all components implement a common `AdComponent` interface to standardize the api for passing data to the components.
-
-Two sample components and the `AdComponent` interface are shown below:
-
-<md-tab-group>
-
-  <md-tab label="hero-job-ad.component.ts">
-    {@example 'cb-dynamic-component-loader/ts/src/app/hero-job-ad.component.ts'}
-  </md-tab>
-
-
-  <md-tab label="hero-profile.component.ts">
-    {@example 'cb-dynamic-component-loader/ts/src/app/hero-profile.component.ts'}
-  </md-tab>
-
-
-  <md-tab label="ad.component.ts">
-    {@example 'cb-dynamic-component-loader/ts/src/app/ad.component.ts'}
-  </md-tab>
-
-
-</md-tab-group>
-
-The final ad banner looks like this:

-Dynamic Forms

-@intro
-Render dynamic forms with FormGroup
-
-@description
-We can't always justify the cost and time to build handcrafted forms, 
-especially if we'll need a great number of them, they're similar to each other, and they change frequently 
-to meet rapidly changing business and regulatory requirements.
-
-It may be more economical to create the forms dynamically, based on metadata that describe the business object model.
-
-In this cookbook we show how to use `formGroup` to dynamically render a simple form with different control types and validation.
-It's a primitive start. 
-It might evolve to support a much richer variety of questions, more graceful rendering, and superior user experience.
-All such greatness has humble beginnings.
-
-In our example we use a dynamic form to build an online application experience for heroes seeking employment.
-The agency is constantly tinkering with the application process.
-We can create the forms on the fly *without changing our application code*.

-**See the <live-example name="cb-dynamic-form"></live-example>**.
-
-<a id="bootstrap"></a>## Bootstrap
-
-We start by creating an `NgModule` called `AppModule`.
-
-In our example we will be using Reactive Forms. 
-
-Reactive Forms belongs to a different `NgModule` called `ReactiveFormsModule`, so in order to access any Reactive Forms directives, we have to import `ReactiveFormsModule` from the `@angular/forms` library.    
-
-We bootstrap our `AppModule` in main.ts.
-
-<md-tab-group>
-
-  <md-tab label="app.module.ts">
-    {@example 'cb-dynamic-form/ts/src/app/app.module.ts'}
-  </md-tab>

-
-  <md-tab label="main.ts">
-    {@example 'cb-dynamic-form/ts/src/main.ts'}
-  </md-tab>
-
-
-</md-tab-group>
-
-
-<a id="object-model"></a>## Question Model
-
-The next step is to define an object model that can describe all scenarios needed by the form functionality.
-The hero application process involves a form with a lot of questions. 
-The "question" is the most fundamental object in the model.
-
-We have created `QuestionBase` as the most fundamental question class.
-
-
-{@example 'cb-dynamic-form/ts/src/app/question-base.ts'}
-
-From this base we derived two new classes in `TextboxQuestion` and `DropdownQuestion` that represent Textbox and Dropdown questions. 
-The idea is that the form will be bound to specific question types and render the appropriate controls dynamically. 
-
-`TextboxQuestion` supports multiple html5 types like text, email, url etc via the `type` property.
-
-
-{@example 'cb-dynamic-form/ts/src/app/question-textbox.ts'}
-
-`DropdownQuestion` presents a list of choices in a select box.
-
-
-{@example 'cb-dynamic-form/ts/src/app/question-dropdown.ts'}
-
-Next we have defined `QuestionControlService`, a simple service for transforming our questions to a `FormGroup`. 
-In a nutshell, the form group consumes the metadata from the question model and allows us to specify default values and validation rules.
-
-
-{@example 'cb-dynamic-form/ts/src/app/question-control.service.ts'}
-
-<a id="form-component"></a>## Question form components
-Now that we have defined the complete model we are ready to create components to represent the dynamic form.
-`DynamicFormComponent` is the entry point and the main container for the form. 
-<md-tab-group>
-
-  <md-tab label="dynamic-form.component.html">
-    {@example 'cb-dynamic-form/ts/src/app/dynamic-form.component.html'}
-  </md-tab>
-
-
-  <md-tab label="dynamic-form.component.ts">
-    {@example 'cb-dynamic-form/ts/src/app/dynamic-form.component.ts'}
-  </md-tab>
-
-
-</md-tab-group>
-
-It presents a list of questions, each question bound to a `<df-question>` component element.
-The `<df-question>` tag matches the `DynamicFormQuestionComponent`,
-the component responsible for rendering the details of each _individual_ question based on values in the data-bound question object.  
-
-<md-tab-group>
-
-  <md-tab label="dynamic-form-question.component.html">
-    {@example 'cb-dynamic-form/ts/src/app/dynamic-form-question.component.html'}
-  </md-tab>
-
-
-  <md-tab label="dynamic-form-question.component.ts">
-    {@example 'cb-dynamic-form/ts/src/app/dynamic-form-question.component.ts'}
-  </md-tab>
-
-
-</md-tab-group>
-
-Notice this component can present any type of question in our model. 
-We only have two types of questions at this point but we can imagine many more.
-The `ngSwitch` determines which type of question to display.
-
-In both components  we're relying on Angular's **formGroup** to connect the template HTML to the
-underlying control objects, populated from the question model with display and validation rules.
-
-`formControlName` and `formGroup` are directives defined in `ReactiveFormsModule`. Our templates can can access these directives directly since we imported `ReactiveFormsModule` from `AppModule`.  
-<a id="questionnaire-metadata"></a>## Questionnaire data`DynamicFormComponent` expects the list of questions in the form of an array bound to  `@Input() questions`.
-
- The set of questions we have defined for the job application is returned from the `QuestionService`. 
- In a real app we'd retrieve these questions from storage.
- 
- The key point is that we control the hero job application questions entirely through the objects returned from `QuestionService`. 
- Questionnaire maintenance is a simple matter of adding, updating, and removing objects from the `questions` array.
- 
-
-{@example 'cb-dynamic-form/ts/src/app/question.service.ts'}
-
-Finally, we display an instance of the form in the `AppComponent` shell.
-
-
-{@example 'cb-dynamic-form/ts/src/app/app.component.ts'}
-
-<a id="dynamic-template"></a>## Dynamic Template
-Although in this example we're modelling a job application for heroes, there are no references to any specific hero question 
-outside the objects returned by `QuestionService`. 
-
-This is very important since it allows us to repurpose the components for any type of survey
-as long as it's compatible with our *question* object model. 
-The key is the dynamic data binding of metadata used to render the form 
-without making any hardcoded assumptions about specific questions. 
-In addition to control metadata, we are also adding validation dynamically.
-
-The *Save* button is disabled until the form is in a valid state. 
-When the form is valid, we can click *Save* and the app renders the current form values as JSON. 
-This proves that any user input is bound back to the data model.
-Saving and retrieving the data is an exercise for another time.
-The final form looks like this:

-{@a template1}
-## Simple Template-Driven Forms
-
-In the template-driven approach, you arrange 
-[form elements](https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/Forms_in_HTML) in the component's template.
-
-You add Angular form directives (mostly directives beginning `ng...`) to help
-Angular construct a corresponding internal control model that implements form functionality.
-We say that the control model is _implicit_ in the template.
-
-To validate user input, you add [HTML validation attributes](https://developer.mozilla.org/en-US/docs/Web/Guide/HTML/HTML5/Constraint_validation) 
-to the elements. Angular interprets those as well, adding validator functions to the control model.
-
-Angular exposes information about the state of the controls including 
-whether the user has "touched" the control or made changes and if the control values are valid.
-
-In the first template validation example, 
-we add more HTML to read that control state and update the display appropriately.
-Here's an excerpt from the template html for a single input box control bound to the hero name:
-
-{@example 'cb-form-validation/ts/src/app/template/hero-form-template1.component.html' region='name-with-error-msg'}
-
-Note the following:
-- The `<input>` element carries the HTML validation attributes: `required`, `minlength`, and `maxlength`.
-
-- We set the `name` attribute of the input box to `"name"` so Angular can track this input element and associate it
-with an Angular form control called `name` in its internal control model.
-
-- We use the `[(ngModel)]` directive to two-way data bind the input box to the `hero.name` property.
-
-- We set a template variable (`#name`) to the value `"ngModel"` (always `ngModel`).
-This gives us a reference to the Angular `NgModel` directive 
-associated with this control that we can use _in the template_
-to check for control states such as `valid` and `dirty`.
-
-- The `*ngIf` on `<div>` element reveals a set of nested message `divs` but only if there are "name" errors and
-the control is either `dirty` or `touched`.
-
-- Each nested `<div>` can present a custom message for one of the possible validation errors.
-We've prepared messages for `required`, `minlength`, and `maxlength`.
-
-The full template repeats this kind of layout for each data entry control on the form.
-#### Why check _dirty_ and _touched_?
-
-We shouldn't show errors for a new hero before the user has had a chance to edit the value.
-The checks for `dirty` and `touched` prevent premature display of errors.
-
-Learn about `dirty` and `touched` in the [Forms](../guide/forms.html) chapter.The component class manages the hero model used in the data binding
-as well as other code to support the view.
-
-
-{@example 'cb-form-validation/ts/src/app/template/hero-form-template1.component.ts' region='class'}
-
-Use this template-driven validation technique when working with static forms with simple, standard validation rules.
-
-Here are the complete files for the first version of `HeroFormTemplateCompononent` in the template-driven approach:
-
-<md-tab-group>
-
-  <md-tab label="template/hero-form-template1.component.html">

-  </md-tab>
-
-
-</md-tab-group>
-
-
-
-
-{@a template2}
-## Template-Driven Forms with validation messages in code
-
-While the layout is straightforward, 
-there are obvious shortcomings with the way we handle validation messages:
-
-* It takes a lot of HTML to represent all possible error conditions. 
-This gets out of hand when there are many controls and many validation rules.
-
-* We're not fond of so much JavaScript logic in HTML.
-
-* The messages are static strings, hard-coded into the template. 
-We often require dynamic messages that we should shape in code.
-
-We can move the logic and the messages into the component with a few changes to 
-the template and component.
-
-Here's the hero name again, excerpted from the revised template ("Template 2"), next to the original version:
-<md-tab-group>
-
-  <md-tab label="hero-form-template2.component.html (name #2)">
-    {@example 'cb-form-validation/ts/src/app/template/hero-form-template2.component.html' region='name-with-error-msg'}
-  </md-tab>
-
-
-  <md-tab label="hero-form-template1.component.html (name #1)">
-    {@example 'cb-form-validation/ts/src/app/template/hero-form-template1.component.html' region='name-with-error-msg'}
-  </md-tab>
-
-
-</md-tab-group>
-
-The `<input>` element HTML is almost the same. There are noteworthy differences:
-- The hard-code error message `<divs>` are gone.
-
-- There's a new attribute, `forbiddenName`, that is actually a custom validation directive.
-It invalidates the control if the user enters "bob" anywhere in the name ([try it](#live-example)).
-We discuss [custom validation directives](#custom-validation) later in this cookbook.
-
-- The `#name` template variable is gone because we no longer refer to the Angular control for this element.
-
--  Binding to the new `formErrors.name` property is sufficent to display all name validation error messages.
-
-#### Component class
-The original component code stays the same.
-We _added_ new code to acquire the Angular form control and compose error messages.
-
-The first step is to acquire the form control that Angular created from the template by querying for it.
-
-Look back at the top of the component template where we set the 
-`#heroForm` template variable in the `<form>` element:
-
-{@example 'cb-form-validation/ts/src/app/template/hero-form-template1.component.html' region='form-tag'}
-
-The `heroForm` variable is a reference to the control model that Angular derived from the template.
-We tell Angular to inject that model into the component class's `currentForm` property using a `@ViewChild` query:
-
-{@example 'cb-form-validation/ts/src/app/template/hero-form-template2.component.ts' region='view-child'}
-
-Some observations:
-
-- Angular `@ViewChild` queries for a template variable when you pass it 
-the name of that variable as a string (`'heroForm'` in this case).
-
-- The `heroForm` object changes several times during the life of the component, most notably when we add a new hero.
-We'll have to re-inspect it periodically.
-
-- Angular calls the `ngAfterViewChecked` [lifecycle hook method](../guide/lifecycle-hooks.html#afterview) 
-when anything changes in the view.
-That's the right time to see if there's a new `heroForm` object.
-
-- When there _is_ a new `heroForm` model, we subscribe to its `valueChanged` _Observable_ property.
-The `onValueChanged` handler looks for validation errors after every user keystroke.  
-
-{@example 'cb-form-validation/ts/src/app/template/hero-form-template2.component.ts' region='handler'}
-
-The `onValueChanged` handler interprets user data entry. 
-The `data` object passed into the handler contains the current element values.
-The handler ignores them. Instead, it iterates over the fields of the component's `formErrors` object.
-
-The `formErrors` is a dictionary of the hero fields that have validation rules and their current error messages.
-Only two hero properties have validation rules, `name` and `power`.
-The messages are empty strings when the hero data are valid.
-
-For each field, the handler
-  - clears the prior error message if any
-  - acquires the field's corresponding Angular form control 
-  - if such a control exists _and_ its been changed ("dirty") _and_ its invalid ...
-  - the handler composes a consolidated error message for all of the control's errors.
-
-We'll need some error messages of course, a set for each validated property, one message per validation rule:
-
-{@example 'cb-form-validation/ts/src/app/template/hero-form-template2.component.ts' region='messages'}
-
-Now every time the user makes a change, the `onValueChanged` handler checks for validation errors and produces messages accordingly.
-
-### Is this an improvement?
-
-Clearly the template got substantially smaller while the component code got substantially larger. 
-It's not easy to see the benefit when there are just three fields and only two of them have validation rules.
-
-Consider what happens as we increase the number of validated fields and rules.
-In general, HTML is harder to read and maintain than code. 
-The initial template was already large and threatening to get rapidly worse as we add more validation message `<divs>`.
-
-After moving the validation messaging to the component, 
-the template grows more slowly and proportionally.
-Each field has approximately the same number of lines no matter its number of validation rules.
-The component also grows proportionally, at the rate of one line per validated field
-and one line per validation message.
-
-Both trends are manageable.
-
-Now that the messages are in code, we have more flexibility. We can compose messages more intelligently. 
-We can refactor the messages out of the component, perhaps to a service class that retrieves them from the server.
-In short, there are more opportunities to improve message handling now that text and logic have moved from template to code.
-
-### _FormModule_ and template-driven forms
-
-Angular has two different forms modules &mdash; `FormsModule` and `ReactiveFormsModule` &mdash; 
-that correspond with the two approaches to form development.
-Both modules come from the same `@angular/forms` library package.
-
-We've been reviewing the "Template-driven" approach which requires the `FormsModule`
-Here's how we imported it in the `HeroFormTemplateModule`.
-
-
-{@example 'cb-form-validation/ts/src/app/template/hero-form-template.module.ts'}
-
-
-We haven't talked about the `SharedModule` or its `SubmittedComponent` which appears at the bottom of every
-form template in this cookbook.  
-
-They're not germane to the validation story. Look at the [live example](#live-example) if you're interested.
-
-
-
-{@a reactive}
-## Reactive Forms
-
-In the template-driven approach, you markup the template with form elements, validation attributes, 
-and `ng...` directives from the Angular `FormsModule`.
-At runtime, Angular interprets the template and derives its _form control model_.
-
-**Reactive Forms** takes a different approach. 
-You create the form control model in code. You write the template with form elements
-and`form...` directives from the Angular `ReactiveFormsModule`.
-At runtime, Angular binds the template elements to your control model based on your instructions.
-
-This approach requires a bit more effort. *You have to write the control model and manage it*.
-
-In return, you can
-* add, change, and remove validation functions on the fly
-* manipulate the control model dynamically from within the component
-* [test](#testing) validation and control logic with isolated unit tests.
-
-The third cookbook sample re-writes the hero form in _reactive forms_ style.
-
-### Switch to the _ReactiveFormsModule_
-The reactive forms classes and directives come from the Angular `ReactiveFormsModule`, not the `FormsModule`.
-The application module for the "Reactive Forms" feature in this sample looks like this:
-
-{@example 'cb-form-validation/ts/src/app/reactive/hero-form-reactive.module.ts'}
-
-The "Reactive Forms" feature module and component are in the `src/app/reactive` folder. 
-Let's focus on the `HeroFormReactiveComponent` there, starting with its template.
-
-### Component template
-
-We begin by changing the `<form>` tag so that it binds the Angular `formGroup` directive in the template
-to the `heroForm` property in the component class. 
-The `heroForm` is the control model that the component class builds and maintains.
-
-
-{@example 'cb-form-validation/ts/src/app/reactive/hero-form-reactive.component.html' region='form-tag'}
-
-Then we modify the template HTML elements to match the _reactive forms_ style.
-Here is the "name" portion of the template again, revised for reactive forms and compared with the template-driven version:
-<md-tab-group>
-
-  <md-tab label="hero-form-reactive.component.html (name #3)">
-    {@example 'cb-form-validation/ts/src/app/reactive/hero-form-reactive.component.html' region='name-with-error-msg'}
-  </md-tab>
-
-
-  <md-tab label="hero-form-template1.component.html (name #2)">
-    {@example 'cb-form-validation/ts/src/app/template/hero-form-template2.component.html' region='name-with-error-msg'}
-  </md-tab>

-
-Key changes:
-- the validation attributes are gone (except `required`) because we'll be validating in code.
-
-- `required` remains, not for validation purposes (we'll cover that in the code), 
-but rather for css styling and accessibility.
-
-A future version of reactive forms will add the `required` HTML validation attribute to the DOM element
-(and perhaps the `aria-required` attribute) when the control has the `required` validator function. 
-
-Until then, apply the `required` attribute _and_ add the `Validator.required` function
-to the control model, as we'll do below.
-- the `formControlName` replaces the `name` attribute; it serves the same
-purpose of correlating the input box with the Angular form control.
-
-- the two-way `[(ngModel)]` binding is gone. 
-The reactive approach does not use data binding to move data into and out of the form controls.
-We do that in code.
-
-The retreat from data binding is a principle of the reactive paradigm rather than a technical limitation.### Component class
-
-The component class is now responsible for defining and managing the form control model. 
-
-Angular no longer derives the control model from the template so we can no longer query for it.
-We create the Angular form control model explicitly with the help of the `FormBuilder`.
-
-Here's the section of code devoted to that process, paired with the template-driven code it replaces:
-<md-tab-group>
-
-  <md-tab label="reactive/hero-form-reactive.component.ts (FormBuilder)">
-    {@example 'cb-form-validation/ts/src/app/reactive/hero-form-reactive.component.ts' region='form-builder'}
-  </md-tab>
-
-
-  <md-tab label="template/hero-form-template2.component.ts (ViewChild)">
-    {@example 'cb-form-validation/ts/src/app/template/hero-form-template2.component.ts' region='view-child'}
-  </md-tab>
-
-
-</md-tab-group>
-
-- we inject the `FormBuilder` in a constructor.
-
-- we call a `buildForm` method in the `ngOnInit` [lifecycle hook method](../guide/lifecycle-hooks.html#hooks-overview)
-because that's when we'll have the hero data. We'll call it again in the `addHero` method.
-A real app would retrieve the hero asynchronously from a data service, a task best performed in the `ngOnInit` hook.- the `buildForm` method uses the `FormBuilder` (`fb`) to declare the form control model.
-Then it attaches the same `onValueChanged` handler (there's a one line difference) 
-to the form's `valueChanged` event and calls it immediately 
-to set error messages for the new control model.
-#### _FormBuilder_ declaration
-The `FormBuilder` declaration object specifies the three controls of the sample's hero form. 
-
-Each control spec is a control name with an array value. 
-The first array element is the current value of the corresponding hero field.
-The (optional) second value is a validator function or an array of validator functions.
-
-Most of the validator functions are stock validators provided by Angular as static methods of the `Validators` class.
-Angular has stock validators that correspond to the standard HTML validation attributes.
-
-The `forbiddenNames` validator on the `"name"` control is a custom validator, 
-discussed in a separate [section below](#custom-validation).
-
- Learn more about `FormBuilder` in a _forthcoming_ chapter on reactive forms. 
-#### Committing hero value changes
-
-In two-way data binding, the user's changes flow automatically from the controls back to the data model properties.
-Reactive forms do not use data binding to update data model properties. 
-The developer decides _when and how_ to update the data model from control values.
-
-This sample updates the model twice:
-1. when the user submits the form
-1. when the user chooses to add a new hero
-
-The `onSubmit` method simply replaces the `hero` object with the combined values of the form:
-
-{@example 'cb-form-validation/ts/src/app/reactive/hero-form-reactive.component.ts' region='on-submit'}
-
-
-This example is "lucky" in that the `heroForm.value` properties _just happen_ to
-correspond _exactly_ to the hero data object properties.The `addHero` method discards pending changes and creates a brand new `hero` model object.
-
-{@example 'cb-form-validation/ts/src/app/reactive/hero-form-reactive.component.ts' region='add-hero'}
-
-Then it calls `buildForm` again which replaces the previous `heroForm` control model with a new one.
-The `<form>` tag's `[formGroup]` binding refreshes the page with the new control model.
-
-Here's the complete reactive component file, compared to the two template-driven component files.
-<md-tab-group>
-
-  <md-tab label="reactive/hero-form-reactive.component.ts (#3)">

-
-{@a custom-validation}
-## Custom validation
-This cookbook sample has a custom `forbiddenNamevalidator` function that's applied to both the 
-template-driven and the reactive form controls. It's in the `src/app/shared` folder
-and declared in the `SharedModule`.
-
-Here's the `forbiddenNamevalidator` function itself:
-
-{@example 'cb-form-validation/ts/src/app/shared/forbidden-name.directive.ts' region='custom-validator'}
-
-The function is actually a factory that takes a regular expression to detect a _specific_ forbidden name
-and returns a validator function.
-
-In this sample, the forbidden name is "bob"; 
-the validator rejects any hero name containing "bob".
-Elsewhere it could reject "alice" or any name that the configuring regular expression matches.
-
-The `forbiddenNamevalidator` factory returns the configured validator function.
-That function takes an Angular control object and returns _either_
-null if the control value is valid _or_ a validation error object.
-The validation error object typically has a property whose name is the validation key ('forbiddenName')
-and whose value is an arbitrary dictionary of values that we could insert into an error message (`{name}`).
-
-Learn more about validator functions in a _forthcoming_ chapter on custom form validation.#### Custom validation directive
-In the reactive forms component we added a configured `forbiddenNamevalidator`
-to the bottom of the `'name'` control's validator function list.
-
-{@example 'cb-form-validation/ts/src/app/reactive/hero-form-reactive.component.ts' region='name-validators'}
-
-In the template-driven component template, we add the selector (`forbiddenName`) of a custom _attribute directive_ to the name's input box
-and configured it to reject "bob".
-
-{@example 'cb-form-validation/ts/src/app/template/hero-form-template2.component.html' region='name-input'}
-
-The corresponding `ForbiddenValidatorDirective` is a wrapper around the `forbiddenNamevalidator`.
-
-Angular forms recognizes the directive's role in the validation process because the directive registers itself
-with the `NG_VALIDATORS` provider, a provider with an extensible collection of validation directives.
-
-{@example 'cb-form-validation/ts/src/app/shared/forbidden-name.directive.ts' region='directive-providers'}
-
-The rest of the directive is unremarkable and we present it here without further comment.
-
-{@example 'cb-form-validation/ts/src/app/shared/forbidden-name.directive.ts' region='directive'}
-
-
-See the [Attribute Directives](../guide/attribute-directives.html) chapter.
-
-
-
-{@a testing}
-## Testing Considerations
-
-We can write _isolated unit tests_ of validation and control logic in _Reactive Forms_.
-
-_Isolated unit tests_ probe the component class directly, independent of its
-interactions with its template, the DOM, other dependencies, or Angular itself.
-
-Such tests have minimal setup, are quick to write, and easy to maintain.
-They do not require the `Angular TestBed` or asynchronous testing practices.
-
-That's not possible with _Template-driven_ forms.
-The template-driven approach relies on Angular to produce the control model and 
-to derive validation rules from the HTML validation attributes.
-You must use the `Angular TestBed` to create component test instances,
-write asynchronous tests, and interact with the DOM.
-
-While not difficult, this takes more time, work and skill &mdash; 
-factors that tend to diminish test code coverage and quality.

-## Angular and _i18n_ template translation
-
-Application internationalization is a challenging, many-faceted effort that 
-takes dedication and enduring commitment.
-Angular's _i18n_ internationalization facilities can help.
-
-This page describes the _i18n_ tools available to assist translation of component template text
-into multiple languages.
-
-
-Practitioners of _internationalization_ refer to a translatable text as a "_message_".
-This page uses the words "_text_" and "_message_" interchangably and in the combination, "_text message_".
-The _i18n_ template translation process has four phases:
-
-1. Mark static text messages in your component templates for translation.
-
-1. An angular _i18n_ tool extracts the marked messages into an industry standard translation source file.
-
-1. A translator edits that file, translating the extracted text messages into the target language, 
-and returns the file to you.
-
-1. The Angular compiler imports the completed translation files, 
-replaces the original messages with translated text, and generates a new version of the application
-in the target language.
-
-You need to build and deploy a separate version of the application for each supported language.
-
-
-{@a i18n-attribute}
-
-## Mark text with the _i18n_ attribute
-
-The Angular `i18n` attribute is a marker for translatable content.
-Place it on every element tag whose fixed text should be translated.
-
-
-~~~ {.alert.is-helpful}
-
-`i18n` is not an Angular _directive_. 
-It's a custom _attribute_, recognized by Angular tools and compilers.
-After translation, the compiler removes it.
-
-
-~~~
-
-In the accompanying sample, an `<h1>` tag displays a simple English language greeting 
-that you translate into Spanish:
-
-{@example 'cb-i18n/ts/src/app/app.component.1.html' region='greeting'}
-
-Add the `i18n` attribute to the tag to mark it for translation.
-
-
-{@example 'cb-i18n/ts/src/app/app.component.1.html' region='i18n-attribute'}
-
-### Help the translator with a _description_ and _intent_
-
-In order to translate it accurately, the translator may 
-need a description of the message.
-Assign a description to the i18n attribute:
-
-
-{@example 'cb-i18n/ts/src/app/app.component.1.html' region='i18n-attribute-desc'}
-
-In order to deliver a correct translation, the translator may need to 
-know your _intent_&mdash;the true _meaning_ of the text 
-within _this particular_ application context.
-In front of the description, add some contextual meaning to the assigned string,
-separating it from the description with the `|` character (`<meaning>|<description>`):
-
-
-{@example 'cb-i18n/ts/src/app/app.component.html' region='i18n-attribute-meaning'}
-
-While all appearances of a message with the _same_ meaning have the _same_ translation, 
-a message with *a variety of possible meanings* could have different translations.
-The Angular extraction tool preserves both the _meaning_ and the _description_ in the translation source file
-to facilitiate contextually-specific translations.
-
-### Translate text without creating an element
-
-Suppose there is a stretch of text that you'd like to translate.
-You could wrap it in a `<span>` tag but for some reason (CSS comes to mind)
-you don't want to create a new DOM element merely to facilitate translation.
-
-Here are two techniques to try.
-
-(1) Wrap the text in an `<ng-container>` element. The `<ng-container>` is never renderered:
-
-
-{@example 'cb-i18n/ts/src/app/app.component.html' region='i18n-ng-container'}
-
-(2) Wrap the text in a pair of HTML comments:
-
-
-{@example 'cb-i18n/ts/src/app/app.component.html' region='i18n-with-comment'}
-
-
-
-
-{@a translate-attributes}
-## Add _i18n-..._ translation attributes
-You've added an image to your template. You care about accessibility too so you add a `title` attribute:
-
-
-{@example 'cb-i18n/ts/src/app/app.component.1.html' region='i18n-title'}
-
-The `title` attribute needs to be translated. 
-Angular i18n support has more translation attributes in the form,`i18n-x`, where `x` is the
-name of the attribute to translate. 
-
-To translate the `title` on the `img` tag from the previous example, write:
-
-
-{@example 'cb-i18n/ts/src/app/app.component.html' region='i18n-title-translate'}
-
-You can also assign a meaning and a description with the `i18n-x="<meaning>|<description>"` syntax.
-
-
-
-{@a cardinality}
-## Handle singular and plural
-
-Different languages have different pluralization rules.
-
-Suppose your application says something about a collection of wolves. 
-In English, depending upon the number of wolves, you could display "no wolves", "one wolf", "two wolves", or "a wolf pack".
-Other languages might express the _cardinality_ differently. 
-
-Here's how you could mark up the component template to display the phrase appropriate to the number of wolves:
-
-
-{@example 'cb-i18n/ts/src/app/app.component.html' region='i18n-plural'}
-
-* The first parameter is the key. It is bound to the component property (`wolves`) 
-that determines the number of wolves.
-* The second parameter identifies this as a `plural` translation type.
-* The third parameter defines a pluralization pattern consisting of pluralization 
-categories and their matching values.
-
-Pluralization categories include:
-* =0
-* =1
-* =5
-* few
-* other
-
-Put the default _English_ translation in braces (`{}`) next to the pluralization category.
-* When you're talking about one wolf, you could write `=1 {one wolf}`.
-* For zero wolves, you could write `=0 {no wolves}`.
-* For two wolves, you could write `=2 {two wolves}`. 
-
-You could keep this up for three, four, and every other number of wolves.
-Or you could specify the **`other`** category as a catch-all for any unmatched cardinality
-and write something like: `other {a wolf pack}`.
-
-This syntax conforms to the
-<a href="http://userguide.icu-project.org/formatparse/messages" target="_blank" title="ICU Message Format">ICU Message Format</a>
-that derives from the 
-<a href="http://cldr.unicode.org/" target="_blank" title="CLDR">Common Locale Data Repository (CLDR),</a>
-which specifies the
-<a href="http://unicode.org/reports/tr35/tr35-numbers.html#Language_Plural_Rules" target="_blank" title="Pluralization Rules">pluralization rules</a>.
-
-
-{@a select}
-## Select among alternative texts
-The application displays different text depending upon whether the hero is male or female.
-These text alternatives require translation too.
-
-You can handle this with a `select` translation. 
-A `select` also follows the
-<a href="http://userguide.icu-project.org/formatparse/messages" target="_blank" title="ICU Message Format">ICU message syntax</a>. 
-You choose among alternative translation based on a string value instead of a number.
-
-The following format message in the component template binds to the component's `gender` 
-property, which outputs either an "m" or an "f".
-The message maps those values to the appropriate translation:
-
-
-{@example 'cb-i18n/ts/src/app/app.component.html' region='i18n-select'}
-
-
-
-{@a ng-xi18n}
-
-## Create a translation source file with the _ng-xi18n_ tool
-
-Use the **_ng-xi18n_ extraction tool** to extract the `i18n`-marked texts 
-into a translation source file in an industry standard format.
-
-This is an Angular CLI tool in the `@angular/compiler-cli` npm package.
-If you haven't already installed the CLI and its `platform-server` peer dependency, do so now:
-
-<code-example language="sh" class="code-shell">
-  npm install @angular/compiler-cli @angular/platform-server --save  
-    
-</code-example>
-
-Open a terminal window at the root of the application project and enter the `ng-xi18n` command:
-
-<code-example language="sh" class="code-shell">
-  ./node_modules/.bin/ng-xi18n  
-    
-</code-example>
-
-
-Windows users may have to quote the command like this: `"./node_modules/.bin/ng-xi18n"`
-By default, the tool generates a translation file named **`messages.xlf`** in the
-<a href="https://en.wikipedia.org/wiki/XLIFF" target="_blank">XML Localisation Interchange File Format (XLIFF, version 1.2)</a>.
-
-
-{@a other-formats}
-### Other translation formats
-
-You can generate a file named **`messages.xmb`** in the 
-<a href="http://cldr.unicode.org/development/development-process/design-proposals/xmb"  target="_blank">XML Message Bundle (XMB)</a> format
-by adding the `--i18nFormat=xmb` flag.
-
-<code-example language="sh" class="code-shell">
-  ./node_modules/.bin/ng-xi18n  --i18nFormat=xmb  
-    
-</code-example>
-
-This sample sticks with the _XLIFF_ format.
-
-
-{@a ng-xi18n-options}
-### Other options
-You may have to specify additional options. 
-For example, if the `tsconfig.json` TypeScript configuration 
-file is located somewhere other than in the root folder,
-you must identify the path to it with the `-p` option:
-<code-example language="sh" class="code-shell">
-  ./node_modules/.bin/ng-xi18n -p path/to/tsconfig.json  
-    ./node_modules/.bin/ng-xi18n  --i18nFormat=xmb -p path/to/tsconfig.json  
-      
-    
-</code-example>
-
-
-
-{@a npm-i18n-script}
-### Add an _npm_ script for convenience
-
-Consider adding a convenience shortcut to the `scripts` section of the `package.json`
-to make the command easier to remember and run:
-<code-example format='.' language='sh'>
-  "scripts": {  
-      "i18n": "ng-xi18n",   
-      ...  
-    }
-</code-example>
-
-Now you can issue command variations such as these:
-<code-example language="sh" class="code-shell">
-  npm run i18n  
-    npm run i18n -- -p path/to/tsconfig.json  
-    npm run i18n -- --i18nFormat=xmb -p path/to/tsconfig.json
-</code-example>
-
-Note the `--` flag before the options. 
-It tells _npm_ to pass every flag thereafter to `ng-xi18n`.
-
-
-{@a translate}
-
-## Translate text messages
-
-The `ng-xi18n` command generates a translation source file 
-in the project root folder named `messages.xlf`.
-The next step is to translate the English language template 
-text into the specific language translation
-files. The cookbook sample creates a Spanish translation file.
-
-
-{@a localization-folder}
-### Create a localization folder
-
-You will probably translate into more than one other language so it's a good idea
-for the project structure to reflect your entire internationalization effort.
-
-One approach is to dedicate a folder to localization and store related assets 
-(for example, internationalization files) there.
-Localization and internationalization are 
-<a href="https://en.wikipedia.org/wiki/Internationalization_and_localization" target="_blank">different but closely related terms</a>.This cookbook follows that suggestion. It has a `locale` folder under the `src/`.
-Assets within the folder carry a filename extension that matches a language-culture code from a
-<a href="https://msdn.microsoft.com/en-us/library/ee825488(v=cs.20).aspx" target="_blank">well-known codeset</a>.
-
-Make a copy of the `messages.xlf` file, put it in the `locale` folder and 
-rename it `messages.es.xlf`for the Spanish language translation.
-Do the same for each target language.
-
-### Translate text nodes
-In the real world, you send the `messages.es.xlf` file to a Spanish translator who fills in the translations
-using one of the
-<a href="https://en.wikipedia.org/wiki/XLIFF#Editors" target="_blank">many XLIFF file editors</a>.
-
-This sample file is easy to translate without a special editor or knowledge of Spanish.
-Open `messages.es.xlf` and find the first `<trans-unit>` section:
-
-
-{@example 'cb-i18n/ts/src/locale/messages.es.xlf.html' region='translated-hello'}
-
-This XML element represents the translation of the `<h1>` greeting tag you marked with the `i18n` attribute. 
-
-Using the _source_, _description_, and _meaning_ elements to guide your translation,
-replace the `<target/>` tag with the Spanish greeting:
-
-{@example 'cb-i18n/ts/src/locale/messages.es.xlf.html' region='translated-hello'}
-
-
-
-~~~ {.alert.is-important}
-
-Note that the tool generates the `id`. **Don't touch it.**
-Its value depends on the content of the message and its assigned meaning.
-Change either factor and the `id` changes as well.
-See the **[translation file maintenance discussion](#maintenance)**.
-
-
-~~~
-
-Translate the other text nodes the same way:
-
-
-{@example 'cb-i18n/ts/src/locale/messages.es.xlf.html' region='translated-other-nodes'}
-
-
-
-{@a translate-plural-select}
-## Translate _plural_ and _select_
-Translating _plural_ and _select_ messages is a little tricky.
-
-The `<source>` tag is empty for `plural` and `select` translation 
-units, which makes them hard to correlate with the original template.
-The `XLIFF` format doesn't yet support the ICU rules; it soon will.
-However, the `XMB` format does support the ICU rules.
-
-You'll just have to look for them in relation to other translation units that you recognize from elsewhere in the source template.
-In this example, you know the translation unit for the `select` must be just below the translation unit for the logo.
-### Translate _plural_ 
-To translate a `plural`, translate its ICU format match values:
-
-
-{@example 'cb-i18n/ts/src/locale/messages.es.xlf.html' region='translated-plural'}
-
-### Translate _select_ 
-The `select` behaves a little differently. Here again is the ICU format message in the component template:
-
-
-{@example 'cb-i18n/ts/src/app/app.component.html' region='i18n-select'}
-
-The extraction tool broke that into _two_ translation units.
-
-The first unit contains the text that was _outside_ the `select`.
-In place of the `select` is a placeholder, `<x id="ICU">`, that represents the `select` message. 
-Translate the text and leave the placeholder where it is.
-
-
-{@example 'cb-i18n/ts/src/locale/messages.es.xlf.html' region='translate-select-1'}
-
-The second translation unit, immediately below the first one, contains the `select` message. Translate that.
-
-
-{@example 'cb-i18n/ts/src/locale/messages.es.xlf.html' region='translate-select-2'}
-
-Here they are together, after translation:
-
-
-{@example 'cb-i18n/ts/src/locale/messages.es.xlf.html' region='translated-select'}
-
-
-<div class='l-main-content'>
-
-</div>
-
-The entire template translation is complete. It's 
-time to incorporate that translation into the application.
-
-<div id='app-pre-translation'>
-
-</div>
-
-### The app before translation
-
-When the previous steps finish, the sample app _and_ its translation file are as follows:
-
-<md-tab-group>
-
-  <md-tab label="src/app/app.component.html">
-    {@example 'cb-i18n/ts/src/app/app.component.html'}
-  </md-tab>
-
-
-  <md-tab label="src/app/app.component.ts">

-  </md-tab>
-
-
-  <md-tab label="src/app/app.module.ts">
-    {@example 'cb-i18n/ts/src/app/app.module.ts'}
-  </md-tab>
-
-
-  <md-tab label="src/main.ts">
-    {@example 'cb-i18n/ts/src/main.1.ts'}
-  </md-tab>
-
-
-  <md-tab label="src/locale/messages.es.xlf">
-    {@example 'cb-i18n/ts/src/locale/messages.es.xlf.html'}
-  </md-tab>
-
-
-</md-tab-group>
-
-
-
-{@a merge}
-
-## Merge the completed translation file into the app
-
-To merge the translated text into component templates,
-compile the application with the completed translation file.
-The process is the same whether the file is in `.xlf` format or 
-in another format (`.xlif` and `.xtb`) that Angular understands.
-
-You provide the Angular compiler with three new pieces of information:
-  * the translation file
-  * the translation file format 
-  * the   <a href="https://en.wikipedia.org/wiki/XLIFF" target="_blank">_Locale ID_</a>
-  (`es` or `en-US` for instance)
-
-_How_ you provide this information depends upon whether you compile with
-the JIT (_Just-in-Time_) compiler or the AOT (_Ahead-of-Time_) compiler. 
-
-  * With [JIT](#jit), you provide the information at bootstrap time.
-  * With [AOT](#aot), you pass the information as `ngc` options. 
-
-
-{@a jit}
-
-### Merge with the JIT compiler
-
-The JIT compiler compiles the application in the browser as the application loads.
-Translation with the JIT compiler is a dynamic process of:
-
-1. Determining the language version for the current user.
-2. Importing the appropriate language translation file as a string constant.
-3. Creating corresponding translation providers to guide the JIT compiler.
-4. Bootstrapping the application with those providers.
-
-Open `index.html` and revise the launch script as follows:
-
-{@example 'cb-i18n/ts/src/index.html' region='i18n'}
-
-In this sample, the user's language is hardcoded as a global `document.locale` variable
-in the `index.html`.
-
-
-{@a text-plugin}
-### SystemJS Text plugin
-
-Notice the SystemJS mapping of `text` to a `systemjs-text-plugin.js`.
-With the help of a text plugin, SystemJS can read any file as raw text and
-return the contents as a string.
-You'll need it to import the language translation file.
-
-SystemJS doesn't ship with a raw text plugin but it's easy to add.
-Create the following `systemjs-text-plugin.js` in the `src/` folder:
-
-{@example 'cb-i18n/ts/src/systemjs-text-plugin.js'}
-
-### Create translation providers
-
-Three providers tell the JIT compiler how to translate the template texts for a particular language
-while compiling the application:
-
-* `TRANSLATIONS` is a string containing the content of the translation file.
-* `TRANSLATIONS_FORMAT` is the format of the file: `xlf`, `xlif` or `xtb`.
-* `LOCALE_ID` is the locale of the target language.
-
-The `getTranslationProviders` function in the following `src/app/i18n-providers.ts` 
-creates those providers based on the user's _locale_
-and the corresponding translation file:
-
-{@example 'cb-i18n/ts/src/app/i18n-providers.ts'}
-
-1. It gets the locale from the global `document.locale` variable that was set in `index.html`.
-
-1. If there is no locale or the language is U.S. English (`en-US`), there is no need to translate.
-  The function returns an empty `noProviders` array as a `Promise`.
-  It must return a `Promise` because this function could read a translation file asynchronously from the server.
-
-1. It creates a transaction filename from the locale according to the name and location convention 
-[described earlier](#localization-folder).
-
-1. The `getTranslationsWithSystemJs` method reads the translation and returns the contents as a string.
-Notice that it appends `!text` to the filename, telling SystemJS to use the [text plugin](#text-plugin). 
-
-1. The callback composes a providers array with the three translation providers.
-
-1. Finally, `getTranslationProviders` returns the entire effort as a promise.
-
-### Bootstrap the app with translation providers
-
-The Angular `bootstrapModule` method has a second, _options_ parameter
-that can influence the behavior of the compiler.
-
-You'll create an _options_ object with the translation providers from `getTranslationProviders`
-and pass it to `bootstrapModule`.
-Open the `src/main.ts` and modify the bootstrap code as follows:
-
-{@example 'cb-i18n/ts/src/main.ts'}
-
-Notice that it waits for the `getTranslationProviders` promise to resolve before
-bootstrapping the app.
-
-The app is now _internationalized_ for English and Spanish and there is a clear path for adding
-more languages.
-
-
-{@a aot}
-
-### _Internationalize_ with the AOT compiler
-
-The JIT compiler translates the application into the target language 
-while compiling dynamically in the browser.
-That's flexible but may not be fast enough for your users. 
-
-The AOT (_Ahead-of-Time_) compiler is part of a build process that 
-produces a small, fast, ready-to-run application package.
-When you internationalize with the AOT compiler, you pre-build 
-a separate application package for each
-language. Then in the host web page (`index.html`), 
-you determine which language the user needs
-and serve the appropriate application package.
-
-This cookbook doesn't cover how to build multiple application packages and 
-serve them according to the user's language preference.
-It does explain the few steps necessary to tell the AOT compiler to apply a translations file.
-
-Internationalization with the AOT compiler requires 
-some setup specifically for AOT compilation. 
-Start with the application project as shown 
-[just before merging the translation file](#app-pre-translation)
-and refer to the [AOT cookbook](aot-compiler.html) to make it _AOT-ready_.
-
-Next, issue an `ngc` compile command for each supported language (including English).
-The result is a separate version of the application for each language.
-
-Tell AOT how to translate by adding three options to the `ngc` command:
-  * `--i18nFile`: the path to the translation file
-  * `--locale`: the name of the locale
-  * `--i18nFormat`: the format of the localization file
-
-For this sample, the Spanish language command would be
-<code-example language="sh" class="code-shell">
-  ./node_modules/.bin/ngc --i18nFile=./locale/messages.es.xlf --locale=es --i18nFormat=xlf  
-    
-</code-example>
-
-
-Windows users may have to quote the command:
-<code-example language="sh" class="code-shell">
-  "./node_modules/.bin/ngc" --i18nFile=./locale/messages.es.xlf --locale=es --i18nFormat=xlf  
-    
-</code-example>
-
-
-
-{@a maintenance}
-## Translation file maintenance and _id_ changes
-  
-As the application evolves, you will change the _i18n_ markup 
-and re-run the `ng-xi18n` extraction tool many times.
-The _new_ markup that you add is not a problem;
-but _most_ changes to _existing_ markup trigger 
-generation of _new_ `id`s for the affected translation units.
-
-After an `id` changes, the translation files are no longer in-sync.
-**All translated versions of the application will fail** during re-compilation. 
-The error messages identify the old `id`s that are no longer valid but 
-they don't tell you what the new `id`s should be.
-
-**Commit all translation message files to source control**, 
-especially the English source `messages.xlf`.
-The difference between the old and the new `messages.xlf` file
- help you find and update `id` changes across your translation files.

-## The problem with *&lt;title&gt;*
-
-The obvious approach is to bind a property of the component to the HTML `<title>` like this:
-<code-example format=''>
-  &lt;title&gt;{{This_Does_Not_Work}}&lt;/title&gt;
-</code-example>
-
-Sorry but that won't work.
-The root component of our application is an element contained within the `<body>` tag.
-The HTML `<title>` is in the document `<head>`, outside the body, making it inaccessible to Angular data binding.
-
-We could grab the browser `document` object and set the title manually.
-That's dirty and undermines our chances of running the app outside of a browser someday.
-Running your app outside a browser means that you can take advantage of server-side
-pre-rendering for near-instant first app render times and for SEO.  It means you could run from
-inside a Web Worker to improve your app's responsiveness by using multiple threads.  And it
-means that you could run your app inside Electron.js or Windows Universal to deliver it to the desktop.
-## Use the *Title* service
-Fortunately, Angular bridges the gap by providing a `Title` service as part of the *Browser platform*.
-The [Title](../api/platform-browser/index/Title-class.html) service is a simple class that provides an API
-for getting and setting the current HTML document title:
-
-* `getTitle() : string` &mdash; Gets the title of the current HTML document.
-* `setTitle( newTitle : string )` &mdash; Sets the title of the current HTML document. 
-
-Let's inject the `Title` service into the root `AppComponent` and expose a bindable `setTitle` method that calls it:
-
-
-{@example 'cb-set-document-title/ts/src/app/app.component.ts' region='class'}
-
-We bind that method to three anchor tags and, voilà!

-## Why we provide the *Title* service in *bootstrap*
-
-We generally recommended providing application-wide services in the root application component, `AppComponent`.
-
-Here we recommend registering the title service during bootstrapping,
-a location we reserve for configuring the runtime Angular environment.
-
-That's exactly what we're doing.
-The `Title` service is part of the Angular *browser platform*.
-If we bootstrap our application into a different platform,
-we'll have to provide a different `Title` service that understands the concept of a "document title" for that specific platform.
-Ideally the application itself neither knows nor cares about the runtime environment.[Back to top](#top)

-Anything you can do with Angular in _TypeScript_, you can also do

-_TypeScript_ is a popular language option for Angular development. 
-Most code examples on the Internet as well as on this site are written in _TypeScript_.

-
-_TypeScript_ 
-<a href="https://www.typescriptlang.org" target="_blank" title='"TypeScript is a typed, superset of JavaScript"'>is a typed superset of _ES6 JavaScript_</a>.
-&nbsp; _ES6 JavaScript_ is a superset of _ES5 JavaScript_. &nbsp; _ES5_ is the kind of JavaScript that runs natively in all modern browsers.
-The transformation of _TypeScript_ code all the way down to _ES5_ code can be seen as "shedding" features.
-
-The downgrade progression is
-* _TypeScript_ to _ES6-with-decorators_
-* _ES6-with-decorators_ to _ES6-without-decorators_ ("_plain ES6_")
-* _ES6-without-decorators_ to _ES5_
-
-When translating from _TypeScript_ to _ES6-with-decorators_, remove 
-[class property access modifiers](http://www.typescriptlang.org/docs/handbook/classes.html#public-private-and-protected-modifiers)
-such as `public` and `private`.
-Remove most of the 
-[type declarations](https://www.typescriptlang.org/docs/handbook/basic-types.html), 
-such as `:string` and `:boolean`
-but **keep the constructor parameter types which are used for dependency injection**.
- 
-
-From _ES6-with-decorators_ to _plain ES6_, remove all 
-[decorators](https://www.typescriptlang.org/docs/handbook/decorators.html)
-and the remaining types.
-You must declare properties in the class constructor (`this.title = '...'`) rather than in the body of the class.
-
-Finally, from _plain ES6_ to _ES5_, the main missing features are `import`
-statements and `class` declarations. 
-
-For _plain ES6_ transpilation you can _start_ with a setup similar to the 
-[_TypeScript_ quickstart](https://github.com/angular/quickstart) and adjust the application code accordingly. 
-Transpile with [Babel](https://babeljs.io/) using the `es2015` preset. 
-To use decorators and annotations with Babel, install the 
-[`angular2`](https://github.com/shuhei/babel-plugin-angular2-annotations) preset as well.

-## Importing and Exporting
-
-### Importing Angular Code
-
-In both _TypeScript_ and _ES6_, you import Angular classes, functions, and other members with _ES6_ `import` statements.
-
-In _ES5_, you access the Angular entities of the [the Angular packages](../glossary.html#scoped-package)
-through the global `ng` object. 
-Anything you can import from `@angular` is a nested member of this `ng` object:

-
-### Exporting Application Code
-
-Each file in a _TypeScript_ or _ES6_ Angular application constitutes an _ES6_ module.
-When you want to make something available to other modules, you `export` it.
-
-_ES5_ lacks native support for modules. 
-In an Angular _ES5_ application, you load each file manually by adding a `<script>` tag to `index.html`. 
-
-~~~ {.alert.is-important}
-
-The order of `<script>` tags is often significant. 
-You must load a file that defines a public JavaScript entity before a file that references that entity.
-
-~~~
-
-The best practice in _ES5_ is to create a form of modularity that avoids polluting the global scope. 
-Add one application namespace object such as `app` to the global `document`.
-Then each code file "exports" public entities by attaching them to that namespace object, e.g., `app.HeroComponent`.
-You could factor a large application into several sub-namespaces 
-which leads to "exports" along the lines of `app.heroQueries.HeroComponent`.
-
-Every _ES5_ file should wrap code in an 
-[Immediately Invoked Function Expression (IIFE)](https://en.wikipedia.org/wiki/Immediately-invoked_function_expression)
-to limit unintentional leaking of private symbols into the global scope.
-
-Here is a `HeroComponent` as it might be defined and "exported" in each of the four language variants.

-### Importing Application Code
-
-In _TypeScript_ and _ES6_ apps, you `import` things that have been exported from other modules.

-## Classes and Class Metadata
-
-### Classes
-
-Most Angular _TypeScript_ and _ES6_ code is written as classes.
-
-Properties and method parameters of _TypeScript_ classes may be marked with the access modifiers
-`private`, `internal`, and `public`. 
-Remove these modifiers when translating to JavaScript.
-
-Most type declarations (e.g, `:string` and `:boolean`) should be removed when translating to JavaScript.
-When translating to _ES6-with-decorators_, ***do not remove types from constructor parameters!***
-
-Look for types in _TypeScript_ property declarations.
-In general it is better to initialize such properties with default values because
-many browser JavaScript engines can generate more performant code.
-When _TypeScript_ code follows this same advice, it can infer the property types
-and there is nothing to remove during translation. 
-
-In _ES6-without-decorators_, properties of classes must be assigned inside the constructor.
-
-_ES5_ JavaScript has no classes. 
-Use the constructor function pattern instead, adding methods to the prototype.

-</md-tab-group>
-
-### Metadata
-
-When writing in _TypeScript_ or _ES6-with-decorators_, 
-provide configuration and metadata by adorning a class with one or more *decorators*. 
-For example, you supply metadata to a component class by preceding its definition with a
-[`@Component`](../api/core/index/Component-decorator.html) decorator function whose
-argument is an object literal with metadata properties.
-
-In _plain ES6_, you provide metadata by attaching an `annotations` array to the _class_.
-Each item in the array is a new instance of a metadata decorator created with a similar metadata object literal.
-
-In _ES5_, you also provide an `annotations` array but you attach it to the _constructor function_ rather than to a class.
-
-See these variations side-by-side:
-
-<md-tab-group>

-  </md-tab>
-
-
-</md-tab-group>
-
-***External Template file***
-
-A large component template is often kept in a separate template file.
-
-{@example 'cb-ts-to-js/ts/src/app/hero-title.component.html'}
-
-The component (`HeroTitleComponent` in this case) then references the template file in its metadata `templateUrl` property:
-<md-tab-group>
-
-  <md-tab label="TypeScript">
-    {@example 'cb-ts-to-js/ts/src/app/hero-title.component.ts' region='templateUrl'}
-  </md-tab>
-
-
-  <md-tab label="ES6 JavaScript with decorators">
-    {@example 'cb-ts-to-js/js-es6-decorators/src/app/hero-title.component.es6' region='templateUrl'}
-  </md-tab>
-
-
-  <md-tab label="ES6 JavaScript">
-    {@example 'cb-ts-to-js/js-es6/src/app/hero-title.component.es6' region='templateUrl'}
-  </md-tab>
-
-
-  <md-tab label="ES5 JavaScript">
-    {@example 'cb-ts-to-js/js/src/app/hero-title.component.js' region='templateUrl'}
-  </md-tab>
-
-
-</md-tab-group>
-
-Note that both the _TypeScript_ and _ES6_ `templateUrl` properties identify the location of the template file _relative to the component module_.
-All three metadata configurations specify the `moduleId` property 
-so that Angular can calculate the proper module address.
-
-The _ES5_ approach shown here does not support modules and therefore there is no way to calculate a _module-relative URL_.
-The `templateUrl` for the _ES5_ code must specify the _path from the project root_ and 
-omits the irrelevant `moduleId` property. 
-
-With the right tooling, the `moduleId` may not be needed in the other JavaScript dialects either.
-But it's safest to provide it anyway.
-

-{@a dsl}
-
-## _ES5_ DSL
-
-This _ES5_ pattern of creating a constructor and annotating it with metadata is so common that Angular 
-provides a convenience API to make it a little more compact and locates the metadata above the constructor, 
-as you would if you wrote in _TypeScript_ or _ES6-with-decorators_.
-
-This _API_ (_Application Programming Interface_) is commonly known as the _ES5 DSL_ (_Domain Specific Language_).
-
-Set an application namespace property (e.g., `app.HeroDslComponent`) to the result of an `ng.core.Component` function call.
-Pass the same metadata object to `ng.core.Component` as you did before.
-Then chain a call to the `Class` method which takes an object defining the class constructor and instance methods.
-
-Here is an example of the `HeroComponent`, re-written with the DSL,
-next to the original _ES5_ version for comparison:

-### Properties with getters and setters
-
-_TypeScript_ and _ES6_ support with getters and setters.
-Here's an example of a read-only _TypeScript_ property with a getter
-that prepares a toggle-button label for the next clicked state:
-
-{@example 'cb-ts-to-js/ts/src/app/hero-queries.component.ts' region='defined-property'}
-
-This _TypeScript_ "getter" property is transpiled to an _ES5_
-<a href="https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Object/defineProperty"
-   target="_blank" title="Defined Properties">defined property</a>.
-The _ES5 DSL_ does not support _defined properties_ directly
-but you can still create them by extracting the "class" prototype and
-adding the _defined property_ in raw JavaScript like this:
-
-{@example 'cb-ts-to-js/js/src/app/hero-queries.component.js' region='defined-property'}
-
-### DSL for other classes
-There are similar DSLs for other decorated classes. 
-You can define a directive with `ng.core.Directive`: 
-
-<code-example>
-  app.MyDirective = ng.core.Directive({  
-      selector: '[myDirective]'  
-    }).Class({  
-      ...  
-    });
-</code-example>
-
-and a pipe with `ng.core.Pipe`:
-<code-example>
-  app.MyPipe = ng.core.Pipe({  
-      name: 'myPipe'  
-    }).Class({  
-      ...  
-    });  
-    
-</code-example>

-{@a interfaces}
-
-## Interfaces
-
-A _TypeScript_ interface helps ensure that a class implements the interface's members correctly.
-We strongly recommend Angular interfaces where appropriate. 
-For example, the component class that implements the `ngOnInit` lifecycle hook method
-should implement the `OnInit` interface.
-
-_TypeScript_ interfaces exist for developer convenience and are not used by Angular at runtime.
-They have no physical manifestation in the generated JavaScript code.
-Just implement the methods and ignore interfaces when translating code samples from _TypeScript_ to JavaScript.

-
-## Input and Output Metadata
-
-### Input and Output Decorators
-
-In _TypeScript_ and _ES6-with-decorators_, you often add metadata to class _properties_ with _property decorators_.
-For example, you apply [`@Input` and `@Output` property decorators](../guide/template-syntax.html#inputs-outputs) 
-to public class properties that will be the target of data binding expressions in parent components.
-
-There is no equivalent of a property decorator in _ES5_ or _plain ES6_. 
-Fortunately, every property decorator has an equivalent representation in a class decorator metadata property.
-A _TypeScript_ `@Input` property decorator can be represented by an item in the `Component` metadata's `inputs` array.
-
-You already know how to add `Component` or `Directive` class metadata in _any_ JavaScript dialect so
-there's nothing fundamentally new about adding another property. 
-But note that what would have been _separate_ `@Input` and `@Output` property decorators for each class property are
-combined in the metadata `inputs` and `outputs` _arrays_.

-</md-tab-group>
-
-In the previous example, one of the public-facing binding names (`cancelMsg`) 
-differs from the corresponding class property name (`notOkMsg`).
-That's OK but you must tell Angular about it so that it can map an external binding of `cancelMsg`
-to the component's `notOkMsg` property.
-
-In _TypeScript_ and _ES6-with-decorators_, 
-you specify the special binding name in the argument to the property decorator.
-
-In _ES5_ and _plain ES6_ code, convey this pairing with the `propertyName: bindingName` syntax in the class metadata.
-
-## Dependency Injection
-Angular relies heavily on [Dependency Injection](../guide/dependency-injection.html) to provide services to the objects it creates.
-When Angular creates a new component, directive, pipe or another service, 
-it sets the class constructor parameters to instances of services provided by an _Injector_.
-
-The developer must tell Angular what to inject into each parameter.
-
-### Injection by Class Type
-
-The easiest and most popular technique in _TypeScript_ and _ES6-with-decorators_ is to set the constructor parameter type
-to the class associated with the service to inject. 
-
-The _TypeScript_ transpiler writes parameter type information into the generated JavaScript.
-Angular reads that information at runtime and locates the corresponding service in the appropriate _Injector_..
-The _ES6-with-decorators_ transpiler does essentially the same thing using the same parameter-typing syntax.
-
-_ES5_ and _plain ES6_ lack types so you must identify "injectables" by attaching a **`parameters`** array to the constructor function. 
-Each item in the array specifies the service's injection token.
-
-As with _TypeScript_ the most popular token is a class, 
-or rather a _constructor function_ that represents a class in _ES5_ and _plain ES6_.
-The format of the `parameters` array varies:
-
-* _plain ES6_ &mdash; nest each constructor function in a sub-array.
-
-* _ES5_ &mdash; simply list the constructor functions.
-
-When writing with _ES5 DSL_, set the `Class.constructor` property to
-an array whose first parameters are the injectable constructor functions and whose
-last parameter is the class constructor itself. 
-This format should be familiar to AngularJS developers.

-</md-tab-group>
-
-### Injection with the @Inject decorator
-
-Sometimes the dependency injection token isn't a class or constructor function.
-
-In _TypeScript_ and _ES6-with-decorators_, you precede the class constructor parameter
-by calling the `@Inject()` decorator with the injection token.
-In the following example, the token is the string `'heroName'`.
-
-The other JavaScript dialects add a `parameters` array to the class contructor function.
-Each item constains a new instance of `Inject`:
-
-* _plain ES6_ &mdash; each item is a new instance of `Inject(token)` in a sub-array.
-
-* _ES5_ &mdash; simply list the string tokens.
-
-When writing with _ES5 DSL_, set the `Class.constructor` property to a function definition
-array as before. Create a new instance of `ng.core.Inject(token)` for each parameter.

-</md-tab-group>
-
-### Additional Injection Decorators
-
-You can qualify injection behavior with injection decorators from `@angular/core`.
-
-In _TypeScript_ and _ES6-with-decorators_, 
-you precede the constructor parameters with injection qualifiers such as:
-* [`@Optional`](../api/core/index/Optional-decorator.html) sets the parameter to `null` if the service is missing
-* [`@Attribute`](../api/core/index/Attribute-interface.html) to inject a host element attribute value
-* [`@ContentChild`](../api/core/index/ContentChild-decorator.html) to inject a content child
-* [`@ViewChild`](../api/core/index/ViewChild-decorator.html) to inject a view child
-* [`@Host`](../api/core/index/Host-decorator.html) to inject a service in this component or its host
-* [`@SkipSelf`](../api/core/index/SkipSelf-decorator.html) to inject a service provided in an ancestor of this component
-
-In _plain ES6_ and _ES5_, create an instance of the equivalent injection qualifier in a nested array within the `parameters` array.
-For example, you'd write `new Optional()` in _plain ES6_ and `new ng.core.Optional()` in _ES5_.
-
-
-When writing with _ES5 DSL_, set the `Class.constructor` property to a function definition
-array as before. Use a nested array to define a parameter's complete injection specification.

-In the example above, there is no provider for the `'titlePrefix'` token.

-
-{@a host-binding}
-
-## Host Binding
-Angular supports bindings to properties and events of the _host element_ which is the
-element whose tag matches the component selector.
-
-### Host Decorators
-
-In _TypeScript_ and _ES6-with-decorators_, you can use host property decorators to bind a host
-element to a component or directive.
-The [`@HostBinding`](../api/core/index/HostBinding-interface.html) decorator
-binds host element properties to component data properties. 
-The [`@HostListener`](../api/core/index/HostListener-interface.html) decorator binds
-host element events to component event handlers.
-
-In _plain ES6_ or _ES5_, add a `host` attribute to the component metadata to achieve the
-same effect as `@HostBinding` and `@HostListener`. 
-
-The  `host` value is an object whose properties are host property and listener bindings:
-
-* Each key follows regular Angular binding syntax: `[property]` for host bindings
-  or `(event)` for host listeners.
-* Each value identifies the corresponding component property or method.

-### Host Metadata
-Some developers prefer to specify host properties and listeners
-in the component metadata. 
-They'd _rather_ do it the way you _must_ do it _ES5_ and _plain ES6_.
-
-The following re-implementation of the `HeroComponent` reminds us that _any property metadata decorator_
-can be expressed as component or directive metadata in both _TypeScript_ and _ES6-with-decorators_.
-These particular _TypeScript_ and _ES6_ code snippets happen to be identical.

-{@a view-child-decorators}
-
-### View and Child Decorators
-
-Several _property_ decorators query a component's nested view and content components.
-
-_View_ children are associated with element tags that appear _within_ the component's template.
-
-_Content_ children are associated with elements that appear _between_ the component's element tags;
-they are projected into an `<ng-content>` slot in the component's template.     The [`@ViewChild`](../api/core/index/ViewChild-decorator.html) and
-[`@ViewChildren`](../api/core/index/ViewChildren-decorator.html) property decorators
-allow a component to query instances of other components that are used in
-its view. 
-
-In _ES5_ and _ES6_, you access a component's view children by adding a `queries` property to the component metadata. 
-The `queries` property value is a hash map.
-
-* each _key_ is the name of a component property that will hold the view child or children.
-* each _value_ is a new instance of either `ViewChild` or `ViewChildren`.

-<h2 id='prereq1'>
-  Prerequisite: Node.js
-</h2>
-
-Install **[Node.js® and npm](https://nodejs.org/en/download/)**
-if they are not already on your machine.
-**Verify that you are running node version `4.6.x` or greater, and npm `3.x.x` or greater**
-by running `node -v` and `npm -v` in a terminal/console window.
-Older versions produce errors.
-
-
-<h2 id='prereq2'>
-  Prerequisite: Visual Studio 2015 Update 3
-</h2>
-
-The minimum requirement for developing Angular applications with Visual Studio is Update 3.
-Earlier versions do not follow the best practices for developing applications with TypeScript.
-To view your version of Visual Studio 2015, go to `Help | About Visual Studio`.
-
-If you don't have it, install **[Visual Studio 2015 Update 3](https://www.visualstudio.com/en-us/news/releasenotes/vs2015-update3-vs)**.
-Or use `Tools | Extensions and Updates` to update to Update 3 directly from Visual Studio 2015.
-
-
-<h2 id='prereq3'>
-  Prerequisite: Configure External Web tools
-</h2>
-
-Configure Visual Studio to use the global external web tools instead of the tools that ship with Visual Studio:
-
-  * Open the **Options** dialog with `Tools` | `Options`
-  * In the tree on the left, select `Projects and Solutions` | `External Web Tools`.
-  * On the right, move the `$(PATH)` entry above the `$(DevEnvDir`) entries. This tells Visual Studio to
-    use the external tools (such as npm) found in the global path before using its own version of the external tools.
-  * Click OK to close the dialog.
-  * Restart Visual Studio for this change to take effect.
-
-Visual Studio will now look first for external tools in the current workspace and 
-if not found then look in the global path and if it is not found there, Visual Studio
-will use its own versions of the tools.
-
-
-<h2 id='prereq4'>
-  Prerequisite: Install TypeScript 2 for Visual Studio 2015
-</h2>
-
-While Visual Studio Update 3 ships with TypeScript support out of the box, it currently doesn’t ship with TypeScript 2, 
-which you need to develop Angular applications.
-
-To install TypeScript 2:
- * Download and install **[TypeScript 2.0 for Visual Studio 2015](http://download.microsoft.com/download/6/D/8/6D8381B0-03C1-4BD2-AE65-30FF0A4C62DA/TS2.0.3-TS-release20-nightly-20160921.1/TypeScript_Dev14Full.exe)**
- * OR install it with npm: `npm install -g typescript@2.0`.
-
-You can find out more about TypeScript 2 support in Visual studio **[here](https://blogs.msdn.microsoft.com/typescript/2016/09/22/announcing-typescript-2-0/)**
-
-At this point, Visual Studio is ready. It’s a good idea to close Visual Studio and 
-restart it to make sure everything is clean.
-
-
-<h2 id='download'>
-  Step 1: Download the QuickStart files
-</h2>
-
-[Download the QuickStart source](https://github.com/angular/quickstart)
-from github. If you downloaded as a zip file, extract the files.
-
-
-<h2 id='create-project'>
-  Step 2: Create the Visual Studio ASP.NET project
-</h2>
-
-Create the ASP.NET 4.x project in the usual way as follows:
-
-* In Visual Studio, select `File` | `New` | `Project` from the menu.
-* In the template tree, select `Templates` | `Visual C#` (or `Visual Basic`) | `Web`.
-* Select the `ASP.NET Web Application` template, give the project a name, and click OK.
-* Select the desired ASP.NET 4.5.2 template and click OK.
-
-In this cookbook we'll select the `Empty` template with no added folders, 
-no authentication and no hosting. Pick the template and options appropriate for your project.
-
-
-<h2 id='copy'>
-  Step 3: Copy the QuickStart files into the ASP.NET project folder
-</h2>
-
-Copy the QuickStart files we downloaded from github into the folder containing the `.csproj` file.
-Include the files in the Visual Studio project as follows:
-
-* Click the `Show All Files` button in Solution Explorer to reveal all of the hidden files in the project.
-* Right-click on each folder/file to be included in the project and select `Include in Project`.
-  Minimally, include the following folder/files:
-  * app folder (answer *No*  if asked to search for TypeScript Typings)
-  * styles.css
-  * index.html
-  * package.json
-  * tsconfig.json
-  
-
-<h2 id='restore'>
-  Step 4: Restore the required packages
-</h2>
-
-Restore the packages required for an Angular application as follows:
-
-* Right-click on the `package.json` file in Solution Explorer and select `Restore Packages`.
-  <br>This uses `npm` to install all of the packages defined in the `package.json` file. 
-  It may take some time.
-* If desired, open the Output window (`View` | `Output`) to watch the npm commands execute.
-* Ignore the warnings.
-* When the restore is finished, a message should say: `npm command completed with exit code 0`.
-* Click the `Refresh` icon in Solution Explorer.
-* **Do not** include the `node_modules` folder in the project. Let it be a hidden project folder.
-
-
-<h2 id='build-and-run'>
-  Step 5: Build and run the app
-</h2>
-
-First, ensure that `index.html` is set as the start page.
-Right-click `index.html` in Solution Explorer and select option `Set As Start Page`.
-
-Build and launch the app with debugger by clicking the **Run** button or press `F5`.
-It's faster to run without the debugger by pressing `Ctrl-F5`.The default browser opens and displays the QuickStart sample application.
-
-Try editing any of the project files. *Save* and refresh the browser to
-see the changes. 
-
-
-<h2 id='routing'>
-  Note on Routing Applications
-</h2>
-
-If this application used the Angular router, a browser refresh could return a *404 - Page Not Found*.
-Look at the address bar. Does it contain a navigation url (a "deep link") ... any path other than `/` or `/index.html`? 
-
-You'll have to configure the server to return `index.html` for these requests.
-Until you do, remove the navigation path and refresh again.
