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
          })
        ]
      }
    }
  },
