我自己用正在用的配置：
//下面uglifyjsplugin 等模块要自己用 npm install 一下

const path = require("path"); const compressionwebpackplugin = require("compression-webpack-plugin"); const productiongzipextensions = ["js", "css"]; const debug = process.env.node_env !== "production"; const uglifyjsplugin = require("uglifyjs-webpack-plugin");const resolve = dir => path.join(__dirname, dir);const is_prod = ["production", "prod"].includes(process.env.node_env);const addstylusresource = rule => {rule.use("style-resouce").loader("style-resources-loader").options({patterns: [resolve("src/assets/stylus/variable.styl")]}); };module.exports = {publicpath: "./", // 根域上下文目录outputdir: "dist", // 构建输出目录assetsdir: "assets", // 静态资源目录 (js, css, img, fonts)lintonsave: false, // 是否开启eslint保存检测，有效值：ture | false | 'error'runtimecompiler: true, // 运行时版本是否需要编译transpiledependencies: [], // 默认babel-loader忽略mode_modules，这里可增加例外的依赖包名// productionsourcemap: false, // 是否在构建生产包时生成 sourcemap 文件，false将提高构建速度productionsourcemap: !is_prod, // 生产环境的 source mapconfigurewebpack: config => {// webpack配置，值位对象时会合并配置，为方法时会改写配置if (debug) {// 开发环境配置config.devtool = "cheap-module-eval-source-map";} else {config.plugins.push(new compressionwebpackplugin({algorithm: "gzip",test: new regexp("\\.(" productiongzipextensions.join("|") ")$"),threshold: 10240,minratio: 0.8}));config.plugins.push(new uglifyjsplugin({uglifyoptions: {compress: {// warnings: true,drop_console: true,drop_debugger: false,pure_funcs: ["console.log"] //移除console}},sourcemap: false,parallel: true}));// 生产环境配置}// object.assign(config, { // 开发生产共同配置// resolve: {// alias: {// '@': path.resolve(__dirname, './src'),// '@c': path.resolve(__dirname, './src/components'),// 'vue$': 'vue/dist/vue.esm.js'// }// }// })},chainwebpack: config => {// webpack链接api，用于生成和修改webapck配置，https://github.com/vuejs/vue-cli/blob/dev/docs/webpack.mdif (debug) {// 本地开发配置} else {// 生产开发配置const types = ["vue-modules", "vue", "normal-modules", "normal"];types.foreach(type =>addstylusresource(config.module.rule("stylus").oneof(type)));}},parallel: require("os").cpus().length > 1, // 构建时开启多进程处理babel编译pluginoptions: {// 第三方插件配置},pwa: {// 单页插件相关配置 https://github.com/vuejs/vue-cli/tree/dev/packages/@vue/cli-plugin-pwa},devserver: {open: true,host: "0.0.0.0",port: 80,https: false,hotonly: false,//跨域我这边是在后台处理的//proxy: {// // 配置跨域//"/api": {//target: "http://xxxxx/",//ws: true,//changorigin: true,//pathrewrite: {// "xxx": ""//}//}//},before: app => {}} };
