vue cli3使用webpack4打包优化

去掉console.log，以及开启gzip

const CompressionPlugin = require('compression-webpack-plugin');//引入gzip压缩插件

  configureWebpack: (config) => {

    if (process.env.NODE_ENV === 'production') {

      //npm install terser-webpack-plugin -D， 去掉console

      config.optimization.minimizer[0].options.terserOptions.compress.drop_console = true

      return {

        plugins: [

          new CompressionPlugin({

            test: /\.js$|\.html$|\.css/,

            threshold: 10240,

            deleteOriginalAssets: false

          })

        ]

      }

    }

  },
