GZIP

• webpack.prod.conf.js 与webpackConfig同级添加以下

if (config.build.productionGzip) {
  const CompressionWebpackPlugin = require('compression-webpack-plugin')

  webpackConfig.plugins.push(
    new CompressionWebpackPlugin({
      asset: '[path].gz[query]',
      algorithm: 'gzip',
      test: new RegExp(
        '\\.(' +
        config.build.productionGzipExtensions.join('|') +
        ')$'
      ),
      threshold: 10240,
      minRatio: 0.8
    })
  )
}

• config/index.js

//改为true
 productionGzip: true,

如果报错，可能是plugin版本太高，降低即可

 npm install --save-dev compression-webpack-plugin@1.1.12

• 去掉所有的console

在 webpack.prod.conf.js 的 UglifyJsPlugin添加一句

compress:{
  warnings:false,
  //添加开始
  drop_console:true,
  pure_funcs:['console.log']
  //添加结束
}

Vue-Cli 3.0 CDN和Gzip压缩

• vue.config.js

安装

npm i -D compression-webpack-plugin

引入

const CompressionWebpackPlugin = require('compression-webpack-plugin')
const path = require('path');

与devServer同级 添加

  configureWebpack: {
    // 使用CDN
    externals: {
      vue: 'Vue',
      'vue-i18n': 'VueI18n',
      axios: 'axios',
      'vue-router': 'VueRouter',
      vuex: 'Vuex',
      'element-ui': 'ELEMENT'
    },
    plugins: [
      new CompressionWebpackPlugin({
        filename: '[path].gz[query]',
        algorithm: 'gzip',
        // test: new RegExp('\\.(' + productionGzipExtensions.join('|') + ')$'),
        test: /\.(js|css)$/,
        threshold: 10240,
        minRatio: 0.8
      })
    ]
