BREAKING CHANGE: web worker platform is now exported via separate packages.
Please use @angular/platform-webworker and @angular/platform-webworker-dynamic
This contains major changes to the compiler, bootstrap of the platforms
and test environment initialization.
Main part of #10043Closes#10164
BREAKING CHANGE:
- Semantics and name of `@AppModule` (now `@NgModule`) changed quite a bit.
This is actually not breaking as `@AppModules` were not part of rc.4.
We will have detailed docs on `@NgModule` separately.
- `coreLoadAndBootstrap` and `coreBootstrap` can't be used any more (without migration support).
Use `bootstrapModule` / `bootstrapModuleFactory` instead.
- All Components listed in routes have to be part of the `declarations` of an NgModule.
Either directly on the bootstrap module / lazy loaded module, or in an NgModule imported by them.
"render" is gramatically incorrect and confusing to developers who used this api.
Since webworker apis were exposed only in master, renaming these before the rc2 release
is not a breaking change
Previously these symbols were exposed via platform-browser-dynamic, then we merged then into platform-browser
thinking that tools would know how to shake off the compiler and other dynamic bits not used with the offline
compilation flow. This turned out to be wrong as both webpack and rollup don't have good enough tree-shaking
capabilities to do this today. We think that in the future we'll be able to merge these two entry points into
one, but we need to give tooling some time before we can do it. In the meantime the reintroduction of the -dynamic
package point allows us to separate the compiler dependencies from the rest of the framework.
This change undoes the previous breaking change that removed the platform-browser-dynamic package.
This changes Angular so that it can be used without reflection (assuming a codegen for injectors).
BREAKIKNG CHANGE:
- Drops `APP_COMPONENT` provider. Instead, inject
`ApplicationRef` and read its `componentTypes` property.
- long form bootstrap has changed into the following:
```
var platform = createPlatform(ReflectiveInjector.resolveAndCreate(BROWSER_PROVIDERS));
var appInjector =
ReflectiveInjector.resolveAndCreate([BROWSER_APP_PROVIDERS, appProviders], platform.injector);
coreLoadAndBootstrap(appInjector, MyApp);
```
BREAKING CHANGE
WORKER_RENDER_APP is now deprecated. Use WORKER_RENDER_APPLICATION instead
WORKER_RENDER_APP_COMMON has been replaced by WORKER_RENDER_APPLICATION_COMMON
closes#6184Closes#6378
BREAKING CHANGE
From the app thread, in both TypeScript and Dart, you bootstrap the app
using `application` instead of `asyncApplication`.
Before:
```TypeScript
platform([WORKER_APP_PLATFORM])
.asyncApplication(setupWebWorker, optionalProviders?)
.then((ref) => ref.bootstrap(RootComponent));
```
Now:
```TypeScript
platform([WORKER_APP_PLATFORM])
.application([WORKER_APP_APPLICATION])
.bootstrap(RootComponent);
```
closes#5857Closes#5862
BREAKING CHANGE:
You can no longer bootstrap a WebWorker or Isolate using `bootstrap` or `bootstrapWebWorker`. Instead you have to do the following:
In TypeScript:
```TypeScript
// index.js
import {WORKER_RENDER_PLATFORM, WORKER_RENDER_APPLICATION, WORKER_SCRIPT} from "angular2/platforms/worker_render";
import {platform} from "angular2/platform";
platform([WORKER_RENDER_PLATFORM])
.application([WORKER_RENDER_APPLICATION, new Provider(WORKER_SCRIPT, {useValue: "loader.js"});
```
```JavaScript
// loader.js
importScripts("https://cdnjs.cloudflare.com/ajax/libs/es6-shim/0.33.3/es6-shim.js", "https://jspm.io/system@0.16.js", "angular2/web_worker/worker.js");
System.import("app");
```
```TypeScript
// app.ts
import {Component, View} from "angular2/core";
import {WORKER_APP_PLATFORM, setupWebWorker} from "angular2/platforms/worker_app";
import {platform} from "angular2/platform";
@Component({
selector: "hello-world"
})
@View({
template: "<h1>Hello {{name}}</h1>
})
export class HelloWorld {
name: string = "Jane";
}
platform([WORKER_APP_PLATFORM])
.asyncApplication(setupWebWorker, optionalProviders?)
.then((ref) => ref.bootstrap(RootComponent));
```
In Dart:
```Dart
// index.dart
import "angular2/platform.dart";
import "angular2/platforms/worker_render.dart";
main() {
platform([WORKER_RENDER_PLATFORM])
.asyncApplication(initIsolate("my_worker.dart"));
}
```
```Dart
// background_index.dart
import "angular2/platform.dart";
import "angular2/platforms/worker_app.dart";
import "package:angular2/src/core/reflection/reflection.dart";
import "package:angular2/src/core/reflection/reflection_capabilities.dart";
@Component(
selector: "hello-world"
)
@View(
template: "<h1>Hello {{name}}</h1>"
)
class HelloWorld {
String name = "Jane";
}
main(List<String> args, SendPort replyTo) {
reflector.reflectionCapabilities = new ReflectionCapabilities();
platform([WORKER_APP_PLATFORM])
.asyncApplication(setupIsolate(replyTo))
.then((ref) => ref.bootstrap(RootComponent));
}
```
You should no longer import from the `angular2/web_worker/worker` and `angular2/web_worker/ui` paths. Instead you can now import directly from core, directives, etc..
The WebWorkerApplication class has been removed. If you want to use ServiceMessageBroker or ClientMessageBroker on the render thread, you must inject their factories via DI.
If you need to use the MessageBus on the render thread you must also obtain it through DI.

This is part of ongoing work to make core platform-independent.
BREAKING CHANGE
All private exports from 'angular2/src/core/facade/{lang,collection,exception_handler}' should be replaced with 'angular2/src/facade/{lang,collection,exception_handler}'.
The directory contains code authored in a style that makes it transpilable to dart. As such, these are not idiomatic examples of Angular 2 usage.
The main purpose of this directory is to enable experimentation with Angular within the angular/angular repository.
