使用terser-webpack-plugin替换uglify插件。具体步骤：

1. 安装

npm install terser-webpack-plugin -D

2. webpack.config.js配置

// 引入插件
const TerserWebpackPlugin = require("terser-webpack-plugin");

// 配置参数
module.exports = {
  ...
  optimization: {
    minimize: true,
    minimizer: [new TerserWebpackPlugin ()],
  },
};

3. 执行npm run dev，bundle.js中的代码被压缩
