refactor(WebWorker): Use the new generic bootstrap. BREAKING CHANGE: You can no longer bootstrap a WebWorker or Isolate using `bootstrap` or `bootstrapWebWorker`. Instead you have to do the following: In TypeScript: ```TypeScript // index.js import {WORKER_RENDER_PLATFORM, WORKER_RENDER_APPLICATION, WORKER_SCRIPT} from "angular2/platforms/worker_render"; import {platform} from "angular2/platform"; platform([WORKER_RENDER_PLATFORM]) .application([WORKER_RENDER_APPLICATION, new Provider(WORKER_SCRIPT, {useValue: "loader.js"}); ``` ```JavaScript // loader.js importScripts("https://cdnjs.cloudflare.com/ajax/libs/es6-shim/0.33.3/es6-shim.js", "https://jspm.io/system@0.16.js", "angular2/web_worker/worker.js"); System.import("app"); ``` ```TypeScript // app.ts import {Component, View} from "angular2/core"; import {WORKER_APP_PLATFORM, setupWebWorker} from "angular2/platforms/worker_app"; import {platform} from "angular2/platform"; @Component({ selector: "hello-world" }) @View({ template: "<h1>Hello {{name}}</h1> }) export class HelloWorld { name: string = "Jane"; } platform([WORKER_APP_PLATFORM]) .asyncApplication(setupWebWorker, optionalProviders?) .then((ref) => ref.bootstrap(RootComponent)); ``` In Dart: ```Dart // index.dart import "angular2/platform.dart"; import "angular2/platforms/worker_render.dart"; main() { platform([WORKER_RENDER_PLATFORM]) .asyncApplication(initIsolate("my_worker.dart")); } ``` ```Dart // background_index.dart import "angular2/platform.dart"; import "angular2/platforms/worker_app.dart"; import "package:angular2/src/core/reflection/reflection.dart"; import "package:angular2/src/core/reflection/reflection_capabilities.dart"; @Component( selector: "hello-world" ) @View( template: "<h1>Hello {{name}}</h1>" ) class HelloWorld { String name = "Jane"; } main(List<String> args, SendPort replyTo) { reflector.reflectionCapabilities = new ReflectionCapabilities(); platform([WORKER_APP_PLATFORM]) .asyncApplication(setupIsolate(replyTo)) .then((ref) => ref.bootstrap(RootComponent)); } ``` You should no longer import from the `angular2/web_worker/worker` and `angular2/web_worker/ui` paths. Instead you can now import directly from core, directives, etc.. The WebWorkerApplication class has been removed. If you want to use ServiceMessageBroker or ClientMessageBroker on the render thread, you must inject their factories via DI. If you need to use the MessageBus on the render thread you must also obtain it through DI. closes #3277 closes #5473 Closes #5519
