// chunkhash,js
  filename: utils.assetsPath('js/[name].[chunkhash].js'),
  chunkFilename: utils.assetsPath('js/[id].[chunkhash].js')


contenthash：build/webpack.prod.conf.js
使用extract-text-webpack-plugin单独编译输出css文件。extract-text-webpack-plugin提供了另外一种hash值：contenthash


  // extract css into its own file
  new ExtractTextPlugin({
   filename: utils.assetsPath('css/[name].[contenthash].css')
  }),


至于缓存这一大块的内容，路漫漫，继续学习
以上这篇vue-cli3中配置alias和打包加hash值操作就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
