Question

我在Angular2和Webpack的VS2015 MVC项目中创建了一个。我正在努力完成三件事。

将所有js捆绑成3个文件（app.bundle.js，polyfills.bundle.js，vendor.bundle.js）
将组件templateUrl中的所有html模板粘贴到app.bundle.js文件中。
缩小js文件会很棒。我还没有达到这一点。

我收到以下错误，app.bundle.js和vendor.bundle.js只是1K文件错误

构建：无法找到模块＆＃39;量角器＆＃39;。 E2E \ app.e2e，spec.ts 构建：重复标识符＆＃39; PropertyKey＆＃39;。 node_modules \ @types \ core-js \ index.d.ts 21
构建：重复标识符＆＃39; export =＆＃39;。 node_modules \ @types \ core-js \ index.d.ts 1513

我认为您收到错误Cannot find module 'protractor'，因为您在为生产生成构建时未排除spec和e2e测试用例文件，因此您需要更改awesome-typescript-loader webpack.config.js文件中的配置如下：

loaders: [
  {
    test: /\.ts$/,
    loaders: ['awesome-typescript-loader', 'angular2-template-loader'],
    exclude: [/\.(spec|e2e)\.ts$/]
  }
]

要缩小js文件，您可以使用UglifyJsPlugin插件进行webpack，如下所示：

const UglifyJsPlugin =  require('webpack/lib/optimize/UglifyJsPlugin');

plugins: [
  new UglifyJsPlugin({
    beautify: false, //prod
    mangle  : {
      screw_ie8: true,
      keep_fnames: true
    },
    compress: { screw_ie8: true },
    comments: false
  });
]
