webpack 爬坑

1.terser-webpack-plugin

js压缩插件，当其他js压缩插件没用时可以考虑

https://www.npmjs.com/package/terser-webpack-plugin

https://github.com/webpack-contrib/terser-webpack-plugin

webpack.config.js

const TerserPlugin = require('terser-webpack-plugin');

module.exports = {
  optimization: {
    minimize: true,
    minimizer: [new TerserPlugin()],
  },
};

深入了解terser插件请查看文档

2.uglifyjs-webpack-plugin

因为uglifyjs不支持es6语法，所以用terser-webpack-plugin替代uglifyjs-webpack-plugin

3. webpack-parallel-uglify-plugin
