当我使用angular-cli构建项目时,它会将所有项目文件捆绑到一个大的主要包中。
我在应用程序中使用了延迟路由,一旦应用程序加载,我就可以正常导航。
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?
以下是angular-cli.json
{
"project": {
"version": "1.0.0-beta.15",
"name": "maddy-test-project"
},
"apps": [
{
"root": "src",
"outDir": "dist",
"assets": "styles/content",
"index": "default.htm",
"main": "main.ts",
"test": "test.ts",
"tsconfig": "tsconfig.json",
"prefix": "",
"mobile": false,
"styles": [
"styles.less"
],

"environments": {
"source": "environments/environment.ts",
"dev": "environments/environment.ts",
"prod": "environments/environment.prod.ts"
}
}
],
"addons": [],
"packages": [],
"e2e": {
"protractor": {
"config": "./protractor.conf.js"
}
},
"test": {
"karma": {
"config": "./karma.conf.js"
}
},

"styleExt": "less",
"prefixInterfaces": false
}
}
下面的是package.json

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/
我们需要做的第一件事是从App组件和主路由配置中删除每个提到的Home组件或HomeModule:
我们在这里可以看到App组件不再导入HomeModule,而是路由配置使用loadChildren来表示如果/ home或任何其他以它开头的url被命中,则应该通过Ajax加载文件home.module调用
很快,要在惰性模块中移动一些逻辑和组件,可以运行以下命令:
ng g module child --routing
然后angular-cli将生成NgModule(app/child/child.module.ts
)和子路由器配置(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' }
最后用一个约束在ChildModule中移动你想要的东西:其他模块(如AppModule)将无法使用任何ChildModule依赖(例如服务)。如果您需要它,一个好的做法是创建一个共享模块。

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。请直接从angular.io网站上查看有关路由和导航的plnkr。
如果以这种方式配置路线,则应该能够在运行类似于以下的服务时生成构建:
注意块文件。在我的项目中,当导航到“危机”和“英雄”路线时,这些块文件会异步加载。
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' }
];
