我开发了react应用,并在 webpack 上实现了不同的方法以减小捆绑的大小。例如codespliting动态导入,splitChunks,压缩和uglifyJs 等,但我的供应商大小仍然是 570 kb
我的 webpack文件

const webpack = require('webpack');
const path = require('path');
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const HtmlWebpackPlugin = require('html-webpack-plugin');
const WebpackMd5Hash = require('webpack-md5-hash');
const CompressionPlugin = require('compression-webpack-plugin');
const VENDOR_LIBS =[
  'antd','axios','moment','rc-time-picker','react',
  'react-dom','react-ga','react-google-maps','react-loadable',
  'react-redux','react-router','react-router-dom','recompose','redux','redux-thunk'
];
const UglifyJsPlugin = require('uglifyjs-webpack-plugin');
const OptimizeCSSAssetsPlugin = require("optimize-css-assets-webpack-plugin");
module.exports = {
    entry:{
      vendor: VENDOR_LIBS,
      main: './src/app.js',
    },
  output: {
      path: path.join(__dirname, 'public'),
      filename: '[name].chunkhash.bundle.js',
      chunkFilename: '[name].chunkhash.bundle.js',
  },

  module: {
    rules: [
      {
        test: /\.js$/,
        exclude: /node_modules/,
        use: {
          loader: "babel-loader"
        }
      },
      {
        test: /\.s?css$/,
        use:  ['style-loader', MiniCssExtractPlugin.loader, 'css-loader', 'sass-loader']
    },{
        test: /\.(gif|svg|jpg|png|ttf|eot|woff(2)?)(\?[a-z0-9=&.]+)?$/,
        loader: "file-loader",
    }
    ]
  },
  plugins: [ 
    new MiniCssExtractPlugin({
      filename: 'style.[contenthash].css',
    }),
    new HtmlWebpackPlugin({
      inject: true,
      hash: true,
      template: './src/index.html',
      filename: 'index.html'
    }),
    new WebpackMd5Hash(),
    new CompressionPlugin({
      algorithm: 'gzip',
      test : /\.js$|\.css$|\.eot?.+$|\.ttf?.+$|\.woff?.+$|\.svg?.+$/,
      threshold: 10240,
      minRatio: 0.8
    }),
    new webpack.DefinePlugin({
        'process.env': {
            NODE_ENV: JSON.stringify('production')
        }
    }),
    new webpack.DefinePlugin({
      'process.env': {
        NODE_ENV: JSON.stringify('production')
      },
    })
  ],
  optimization: {
    splitChunks: {
      cacheGroups: {
        vendor: {
          test: /[\\/]node_modules[\\/]/,
                    name: 'vendors',
          chunks: 'all',
          minChunks: 2
        },
      }
    },
    runtimeChunk: true,
    minimizer: [
      new UglifyJsPlugin({
        cache: true,
        parallel: true,
        sourceMap: true,
        uglifyOptions: {
          compress: {
            inline: false
          }
        }
      }),
      new OptimizeCSSAssetsPlugin({})
    ],
  },
};

实际上,我的Web应用大部分时间仅在移动设备上打开,并且大多数都是3g网络,因此需要花费更多时间。因此,有什么方法可以减少我的vendor.js文件。
我已经在服务器端实现了brotli算法,所以现在是440 kb。
我想减少到250 kb

您是否考虑过“捆绑式装载机”?该模块将帮助您分块关键的JS。自然,这需要您的主要对象进行一些重构/架构:'./src/app.js' 您的模块必须异步加载。

如果您通知模式:“生产”,那么webpack-4会自动为您完成一些自动化操作,这样您就可以避免使用许多插件并拥有更整洁的配置文件。
