Angular 2 网络工作者 - UI 不是运行

Question

我在 Web Worker 中有一个 angular2 应用程序运行。从外观上看，一切都如我所料运行，但 DOM 似乎什么也没有发生。例如，我在应用程序加载时显示预加载器，但它永远不会被实际应用程序替换 UI。

<my-app>Loading...</my-app>

当 AppModule 加载时，我的应用程序中没有呈现任何内容...即使我看到我所有的组件和服务运行完全符合我在后台工作程序中的预期...整个应用程序是运行很好 - 只是没有 UI.

import { NgModule } from '@angular/core';
import { HttpModule, XSRFStrategy } from '@angular/http';
import { FormsModule } from '@angular/forms';
import { BrowserModule } from '@angular/platform-browser';
import { WorkerAppModule } from '@angular/platform-webworker';
import { WORKER_APP_LOCATION_PROVIDERS } from '@angular/platform-webworker';

import { AppComponent } from './app.component';
import { NoXSRFStrategy } from './common/backends/XSRFStrategies';

@NgModule({
    imports: [
        BrowserModule,
        HttpModule,
        FormsModule,
        routing,  

        WorkerAppModule         
    ],
    declarations: [
        AppComponent
    ],
    providers: [
        { provide: XSRFStrategy, useClass: NoXSRFStrategy },

        WORKER_APP_LOCATION_PROVIDERS           
    ],
    bootstrap: [AppComponent]
})
export class AppModule {    
    constructor() { }    
}

在我的main.ts

UI_THREAD_CHANNEL = 'UI_THREAD_CHANNEL'
bootstrapWorkerUi('/webworker-loader.js').then((hWnd) => {

                // register methods the WebWorker needs to run on the UI thread.
                let brokerFactory: ServiceMessageBrokerFactory = hWnd.injector.get(ServiceMessageBrokerFactory);
                let broker = brokerFactory.createMessageBroker(UI_THREAD_CHANNEL, false);

                broker.registerMethod('redirect', [PRIMITIVE], (href: string) => {
                    window.location.href = href;
                });
            });

在我的webworker中-main.ts

import { platformWorkerAppDynamic } from '@angular/platform-webworker-dynamic';
import { AppModule } from './app.module';
const platform = platformWorkerAppDynamic();
platform.bootstrapModule(AppModule);

当我不使用 web-worker 时，一切正常。我真的很接近让这项工作我相信......只是找不到我所缺少的东西。我怀疑有些东西我没有加载 - 或者我不知道与路由相关的东西。

想通了。

问题是必须向 main.ts 中的 bootstrapWorkerUi 提供额外的提供程序 - 特别是来自 @angular/platform-webworker.

的 WORKER_UI_LOCATION_PROVIDERS

新（工作）main.ts

import { WORKER_UI_LOCATION_PROVIDERS, bootstrapWorkerUi, 
ServiceMessageBrokerFactory } from '@angular/platform-webworker';

UI_THREAD_CHANNEL = 'UI_THREAD_CHANNEL'
bootstrapWorkerUi('/webworker-loader.js', WORKER_UI_LOCATION_PROVIDERS).then((hWnd) => {

    // register methods the WebWorker needs to run on the UI thread.
    let brokerFactory: ServiceMessageBrokerFactory = hWnd.injector.get(ServiceMessageBrokerFactory);
    let broker = brokerFactory.createMessageBroker(UI_THREAD_CHANNEL, false);

    broker.registerMethod('redirect', [PRIMITIVE], (href: string) => {
        window.location.href = href;
    });
});
