npm install uglifyjs-webpack-plugin --save-dev

配置

在文件​​vue.config.js​​里进行配置

// 引入
const UglifyJsPlugin = require("uglifyjs-webpack-plugin");

module.exports = {
  chainWebpack: config => {
    if (process.env.NODE_ENV === 'production') {
      // js,css代码的最小化压缩
      config.optimization.minimize(true);
    }
  },
  configureWebpack: config => {
    if (process.env.NODE_ENV === 'production') {
      config.optimization.minimizer = [
        new UglifyJsPlugin({
          uglifyOptions: {
            warnings: false,
            compress: {
              drop_console: true,
              drop_debugger: false,
              pure_funcs: ["console.log"]
            }
          }
        })
      ];
    }
  }
}
