Question

Angular v.4和webpack

我正在寻找非常简单问题的答案。

如何将node_module文件夹捆绑为vendor.js，但不捆绑应用程序代码。在页面加载似乎有超过300个角度代码请求加载内部文件。

如果我能够合并所有node_modules库，我将节省大量的浏览器请求。

我跟着这个example能够让它运行但它也捆绑了库和你的应用程序代码。我能够成功生成vendor.js，但我不确定在index.html中添加vendor.js后，我的应用程序代码将如何识别@angular lib引用。目前正在使用systemjs.config.js来解决这个问题

@angular/code : 'npm:@angular/code/bundle/core.umd.js' 
..
..

正是因为我认为应用程序崩溃所发生的事情，它无法从我的应用程序代码中找到对@angular的引用。

是否可以将node_module文件夹绑定到vendor.js，并且仍然可以在我的应用程序代码中使用而无需捆绑应用程序代码？

添加webpack config

webpack.config.js

module.exports = require('./config/webpack.prod.js');

webpack.common.js

var webpack = require('webpack');
var HtmlWebpackPlugin = require('html-webpack-plugin');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var helpers = require('./helpers');

module.exports = {
  entry: {
    'polyfills': './src/polyfills.ts',
    'vendor': './src/vendor.ts',
    'app': './src/main.ts'
  },

  resolve: {
    extensions: ['.ts', '.js']
  },

  module: {
    rules: [
      {
        test: /\.ts$/,
        loaders: [
          {
            loader: 'awesome-typescript-loader',
            options: { configFileName: helpers.root('src', 'tsconfig.json') }
          } , 'angular2-template-loader'
        ]
      },
      {
        test: /\.html$/,
        loader: 'html-loader'
      },
      {
        test: /\.(png|jpe?g|gif|svg|woff|woff2|ttf|eot|ico)$/,
        loader: 'file-loader?name=assets/[name].[hash].[ext]'
      },
      {
        test: /\.css$/,
        exclude: helpers.root('src', 'app'),
        loader: ExtractTextPlugin.extract({ fallbackLoader: 'style-loader', loader: 'css-loader?sourceMap' })
      },
      {
        test: /\.css$/,
        include: helpers.root('src', 'app'),
        loader: 'raw-loader'
      }
    ]
  },

  plugins: [
    // Workaround for angular/angular#11580
    new webpack.ContextReplacementPlugin(
      // The (\\|\/) piece accounts for path separators in *nix and Windows
      /angular(\\|\/)core(\\|\/)(esm(\\|\/)src|src)(\\|\/)linker/,
      helpers.root('./src'), // location of your src
      {} // a map of your routes
    ),

    new webpack.optimize.CommonsChunkPlugin({
      name: ['app', 'vendor', 'polyfills']
    }),

    new HtmlWebpackPlugin({
      template: 'src/index.html'
    })
  ]
};

webpack.prod.js

var webpack = require('webpack');
var webpackMerge = require('webpack-merge');
var ExtractTextPlugin = require('extract-text-webpack-plugin');
var commonConfig = require('./webpack.common.js');
var helpers = require('./helpers');

const ENV = process.env.NODE_ENV = process.env.ENV = 'production';

module.exports = webpackMerge(commonConfig, {
  devtool: 'source-map',

  output: {
    path: helpers.root('dist'),
    publicPath: '/',
    filename: '[name].[hash].js',
    chunkFilename: '[id].[hash].chunk.js'
  },

  plugins: [
    new webpack.NoEmitOnErrorsPlugin(),
    new webpack.optimize.UglifyJsPlugin({ // https://github.com/angular/angular/issues/10618
      mangle: {
        keep_fnames: true
      }
    }),
    new ExtractTextPlugin('[name].[hash].css'),
    new webpack.DefinePlugin({
      'process.env': {
        'ENV': JSON.stringify(ENV)
      }
    }),
    new webpack.LoaderOptionsPlugin({
      htmlLoader: {
        minimize: false // workaround for ng2
      }
    })
  ]
});

仅限angular2 bundle node_modules而不是应用程序代码
