使用 angular-cli webpack 创建多个包

Question

当我使用 angular-cli 构建项目时，它将所有项目文件捆绑到一个大的主包中。

我在应用程序中使用了惰性路由，应用程序加载后我可以正常导航。

有没有一种方法可以根据延迟加载的路由模块将主包分成多个文件？

下面是angular-cli.json

中的配置

    {
  "project": {
    "version": "1.0.0-beta.15",
    "name": "maddy-test-project"

    {

如果将要延迟加载的区域拆分为单独的模块，则应该能够生成多个包。看一下直接从 angular.io 网站获取的有关路由和导航的 plnkr。如果你以这种方式配置你的路由，你应该能够在运行 ng serve 类似于：
时生成一个构建注意块文件。在我的项目中，这些块文件在导航到 'crisis' 和 'heroes' 路由时被异步加载。

export const routes: Routes = [
  { path: '', redirectTo: 'contact', pathMatch: 'full'},
  { path: 'crisis', loadChildren: 'app/crisis/crisis.module#CrisisModule' },
  { path: 'heroes', loadChildren: 'app/hero/hero.module#HeroModule' }
];

是NgModule和RouterModule.forChild()的作用。这是一篇非常好的文章，用于启动大型 Angular 2 模块化应用程序开发：http://blog.angular-university.io/angular2-ngmodule/

The first thing that we need to do is to remove every mention of the Home component or the HomeModule from the App component and the main routing configuration:

We can see here that the App component no longer imports HomeModule, instead the routing config uses loadChildren to say that if /home or any other url starting with it gets hit, then the file home.module should be loaded via an Ajax call.

很快，要移动惰性模块中的一些逻辑和组件，您可以运行这个命令：

ng g module child --routing

然后angular-cli会生成一个NgModule（app/child/child.module.ts）和一个子路由配置（app/child/child-routing.module.ts）。

延迟加载此子路由器的路由将是：

 { path: 'child', loadChildren: 'app/child/child.module#ChildModule' }

最后在你的 ChildModule 中移动你想要的东西，但有一个限制：其他模块（如 AppModule）将无法使用任何 ChildModule 依赖项（例如服务）。如果需要，一个好的做法是创建一个共享模块。
