<think>我们注意到虽然配置了优化，但打包体积仍然很大，特别是chunk-vendors.js文件（2.28MB）。这可能是由于某些大型库（如ElementUI、ECharts等）被包含在内。我们需要进一步优化。 ###深度优化方案####1.按需引入组件库如果使用ElementUI，确保按需引入：```javascript//在babel.config.js中配置module.exports= {presets:['@vue/cli-plugin-babel/preset'],plugins:[['component',{libraryName: 'element-ui',styleLibraryName:'theme-chalk'}]] }``` ####2.使用CDN引入外部库```javascript// vue.config.jsmodule.exports =defineConfig({//...其他配置configureWebpack: {externals:{//将需要CDN引入的库配置为外部依赖'vue':'Vue','vue-router': 'VueRouter','element-ui': 'ELEMENT','axios': 'axios','echarts': 'echarts'}},chainWebpack: config=> {//添加CDN配置config.plugin('html').tap(args=> {args[0].cdn= {css: ['https://cdn.jsdelivr.net/npm/[email protected]/lib/theme-chalk/index.css'],js:['https://cdn.jsdelivr.net/npm/[email protected]/dist/vue.min.js','https://cdn.jsdelivr.net/npm/[email protected]/dist/vue-router.min.js','https://cdn.jsdelivr.net/npm/[email protected]/lib/index.js','https://cdn.jsdelivr.net/npm/[email protected]/dist/axios.min.js','https://cdn.jsdelivr.net/npm/[email protected]/dist/echarts.min.js']}returnargs})}}) ``````html<!--public/index.html中添加CDN引用--> <head><% for(vari inhtmlWebpackPlugin.options.cdn &&htmlWebpackPlugin.options.cdn.css) {%><linkrel="stylesheet"href="<%=htmlWebpackPlugin.options.cdn.css[i]%>"/><% }%> </head><body><!--... --><%for (var iin htmlWebpackPlugin.options.cdn&& htmlWebpackPlugin.options.cdn.js){ %><script src="<%= htmlWebpackPlugin.options.cdn.js[i] %>"></script><% }%> </body>``` ####3.路由懒加载```javascript//router.jsconst Home= ()=> import(/*webpackChunkName:"home" */'./views/Home.vue')const About= ()=> import(/*webpackChunkName:"about" */'./views/About.vue') ```####4.压缩图片的终极方案使用在线工具压缩大图片（如0001.bbc23d94.jpg），然后替换原文件。####5.升级到Vue3（如果可行） Vue3的Tree-shaking更高效，能进一步减小体积。 ###执行优化后的预期效果|文件|优化前|优化后（预计） ||---------------------|----------|---------------|| chunk-vendors.js|2.28MB|0.5-1MB||总构建体积|2.6 MB|1.0-1.5 MB||图片体积|1.85MB|0.3-0.5 MB|###完整优化后的vue.config.js```javascriptconst {defineConfig} =require('@vue/cli-service')const BundleAnalyzerPlugin =require('webpack-bundle-analyzer').BundleAnalyzerPlugin; module.exports =defineConfig({transpileDependencies: true,publicPath: './',configureWebpack:{externals: {'vue':'Vue','vue-router': 'VueRouter','element-ui': 'ELEMENT','axios': 'axios','echarts': 'echarts'},plugins:process.env.NODE_ENV=== 'production'?
