1. 安装所需库

yarn add webpack webpack-cli webpack-command webpack-dev-server --dev

yarn add ts-loader html-webpack-plugin clean-webpack-plugin friendly-errors-webpack-plugin extract-text-webpack-plugin webpack-bundle-analyzer babel-plugin-syntax-dynamic-import image-webpack-loader MiniCssExtractPlugin --dev

yarn add babel-loader babel-core @babel/preset-env @babel/core @babel/cli @babel/preset-react @babel/preset-typescript @babel/polyfill @babel/plugin-proposal-class-properties --dev

yarn add css-loader node-sass sass-loader file-loader url-loader json-loader --dev

2. 新建webpack.config.js

const path = require('path');
const htmlWebpackPlugin = require('html-webpack-plugin')
const {CleanWebpackPlugin} = require('clean-webpack-plugin')
const { BundleAnalyzerPlugin } = require('webpack-bundle-analyzer');
const UglifyJsPlugin = require('uglifyjs-webpack-plugin');
const CompressionPlugin = require('compression-webpack-plugin');//引入gzip压缩插件
const MiniCssExtractPlugin = require("mini-css-extract-plugin");


module.exports = {
  entry: './src/index.js',//入口地址
  output: { //打包文件的输出位置
    path: path.resolve(__dirname, 'dist'),
    filename: 'main.[chunkhash:8].js',
    chunkFilename: 'chunks/[name].[hash:8].js',
  },
  devServer: {
    static: "./public",//本地服务器所加载的页面所在的目录
    historyApiFallback: true,//不跳转
    hot: true,//实时刷新
    compress: true, //gzip压缩
  },
  module:{
    rules:[
      {
        test: /\.(js|jsx|mjs)$/,
        loader: "babel-loader",
        exclude: /node_modules/,
      },
      {
        test: /\.(ts|tsx)?$/,
        loader: "ts-loader",
        exclude: /node_modules/,
      },
      {
        test:/\.css$/,
        use: [
          {
            loader: MiniCssExtractPlugin.loader,
            options: {
              publicPath: '../'
            }
          },
          "css-loader"
        ]
      },
      {
        test:/\.scss$/,
        use: [
          {
            loader: MiniCssExtractPlugin.loader,
            options: {
              publicPath: '../'
            }
          },
          "css-loader",
          'sass-loader'
        ]
      },
      {
        test: /\.(jpe?g|png|gif|svg)$/,
        use:[
          {
            loader:'url-loader',
            options: {
              limit:8*1024,
              name: '[name]_[hash:6].[ext]'//这里我们给图片名添加了6位的hash值
            }
          },
          'image-webpack-loader'
        ],
      },
      {
        test: /\.(mp4|mp3|webm|0gg|wav|flac|acc)$/,
        loader:'url-loader',
        options: {
          limit:8*1024,
          name: '[name]_[hash:6].[ext]'
        }
      },
      {
        test: /\.(wogg2?|eot|ttf|otf)$/,
        loader:'url-loader',
        options: {
          limit:8*1024,
          name: '[name]_[hash:6].[ext]'
        }
      },
      {
        test: /\.json$/,
        use: ['json-loader'],
        type: 'javascript/auto'
      }
    ],
  },
  plugins:[
    new htmlWebpackPlugin({
      template:path.join(__dirname,'./public/index.html'),
      filename: 'index.html'
    }),
    new CleanWebpackPlugin({}),
    new BundleAnalyzerPlugin({ analyzerPort: 8919 }),
    new UglifyJsPlugin({
      uglifyOptions: {
        warnings: false,
        compress: {
          drop_console: true,
          drop_debugger: true,
          pure_funcs: ['console.log']
        }
      }
    }),
    new MiniCssExtractPlugin({
      filename: 'main.[chunkhash:8].css',
      chunkFilename: 'chunks/[name].[hash:8].css',
    }),
    new webpack.optimize.UglifyJsPlugin({
      compress: {
        warnings: false
      }
    })
  ],
  mode:'production', //环境  production
  resolve:{
    extensions:['.js','.ts','.tsx','.jsx','.mjs']
  },
  optimization: {
    splitChunks: {
      chunks: 'async',
      minSize: 20000,
      minRemainingSize: 0,
      minChunks: 1,
      maxAsyncRequests: 30,
      maxInitialRequests: 30,
      enforceSizeThreshold: 50000,
      cacheGroups: {
        defaultVendors: {
          test: /[\\/]node_modules[\\/]/,
          priority: -10,
          reuseExistingChunk: true,
        },
        default: {
          minChunks: 2,
          priority: -20,
          reuseExistingChunk: true,
        },
      },
    },
  },
};

3. 新建.babelrc

{
  "presets": [
      "@babel/preset-env",
      "@babel/preset-react"
  ],
  "plugins": [
      "@babel/plugin-proposal-class-properties"
  ]
}

4. 修改tsconfig.json

"noEmit": false,

5. 打包
