Angular2 RC7和angular-cli Webpack中的延迟加载 [英] Lazy loading in Angular2 RC7 and angular-cli webpack

问题描述

我已经使用ng new创建了一个新的应用程序，但是当我尝试配置模块以使用延迟加载进行加载时，我不断收到错误消息，找不到该模块.

I have created a new app using ng new but when I try to configure a module to load using lazy loading I keep getting an error that the module cannot be found.

EXCEPTION: Uncaught (in promise): Error: Cannot find module 'app/home/home.module'

import { ModuleWithProviders } from '@angular/core';

const appRoutes: Routes = [{

    redirectTo: 'home',
    pathMatch: 'full'
},
{
    path: `home`,
    loadChildren: `app/home/home.module`
}];
export const routing: ModuleWithProviders = RouterModule.forRoot(appRoutes);

app.module.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { HttpModule } from '@angular/http';

import { AppComponent } from './app.component';

import { routing } from './app.routing';

@NgModule({
  declarations: [
     AppComponent
  ],
  imports: [
    BrowserModule,
    FormsModule,
    HttpModule,
    routing
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

app.component.ts

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  templateUrl: 'app.component.html',
  styleUrls: ['app.component.css']
})
export class AppComponent {
  title = 'app works!';
}

app.component.html

<router-outlet></router-outlet>

我确定我缺少一些愚蠢的东西，但是我尝试了各种选择，但到目前为止没有任何效果.有了我的配置，我会丢失任何东西吗?

I'm sure I'm missing something stupid but I tried various options and nothing has worked so far. Given my configuration, am I missing anything?

推荐答案

使用RC7，您可以执行以下操作:

With RC7, you can do as follow:

const appRoutes: Routes = [
  {
    path: 'home',
    loadChildren: 'app/home/home.module#HomeModule',
  }
];

别忘了"#"

然后终止服务并重新启动

Then kill ng serve and restart it

它将与angular-cli @ webpack一起使用

It will works with angular-cli@webpack

P.S:角度惯例是在延迟加载的文件夹前面加上(+)，例如+ home/

P.S: The angular convention is to prefix lazy loaded folders with a (+) e.g. +home/
