完整版配置:
const path = require("path");
const UglifyPlugin = require("uglifyjs-webpack-plugin");
module.exports = {
// 基本路径
/* 部署生产环境和开发环境下的URL:可对当前环境进行区分,baseUrl 从 Vue CLI 3.3 起已弃用,要使用publicPath */
/* baseUrl: process.env.NODE_ENV === 'production' ? './' : '/' */
publicPath: process.env.NODE_ENV === "production" ? "./" : "./",
// 输出文件目录
outputDir: "dist",
// eslint-loader 是否在保存的时候检查
lintOnSave: true,
// use the full build with in-browser compiler?
// https://vuejs.org/v2/guide/installation.html#Runtime-Compiler-vs-Runtime-only
// compiler: false,
runtimeCompiler: true,
// 调整内部的 webpack 配置。
// 查阅 https://github.com/vuejs/vue-doc-zh-cn/vue-cli/webpack.md
// webpack配置
// see https://github.com/vuejs/vue-cli/blob/dev/docs/webpack.md
chainWebpack: () => {},
configureWebpack: config => {

// 为生产环境修改配置...

// 将每个依赖包打包成单独的js文件
var optimization = {
runtimeChunk: "single",
splitChunks: {
chunks: "all",
maxInitialRequests: Infinity,
minSize: 20000, // 依赖包超过20000bit将被单独打包
cacheGroups: {
vendor: {
test: /[\\/]node_modules[\\/]/,
name(module) {
// get the name. E.g. node_modules/packageName/not/this/part.js
// or node_modules/packageName
const packageName = module.context.match(
/[\\/]node_modules[\\/](.*?)([\\/]|$)/
)[1];
// npm package names are URL-safe, but some servers don't like @ symbols

}
}
}
},

}
}
})
]
};
Object.assign(config, {

});
} else {
// 为开发环境修改配置...

var optimization2 = {

// 开发生产共同配置
// externals: {
// 'vue': 'Vue',
// 'element-ui': 'ELEMENT',
// 'vue-router': 'VueRouter',
// 'vuex': 'Vuex'
// } // 防止将某些 import 的包(package)打包到 bundle 中,而是在运行时(runtime)再去从外部获取这些扩展依赖(用于csdn引入)

// vue-loader 配置项

简洁版配置:
const path = require("path");
const resolve = function(dir) {
return path.join(__dirname, dir);
};
module.exports = {
publicPath: process.env.NODE_ENV === "production" ? "./" : "./",
outputDir: "dist",
assetsDir: "static",
lintOnSave: true, // 是否开启eslint保存检测
productionSourceMap: false, // 是否在构建生产包时生成sourcdeMap
chainWebpack: config => {
config.resolve.alias
.set("@", resolve("src"))
.set("@v", resolve("src/views"))
.set("@c", resolve("src/components"))
.set("@u", resolve("src/utils"))
.set("@s", resolve("src/service")); /* 路径别名配置 */
config.optimization.runtimeChunk("single");
},
devServer: {
/* 本地ip地址 */
host: "0.0.0.0", //局域网和本地访问
port: "8080",
hot: true,
/* 自动打开浏览器 */
open: false,
overlay: {
warning: false,
error: true
},
/* 跨域代理 */
proxy: {
"/api": {
/* 目标代理服务器地址 */
target: "http://xxxx.xx", //api地址
/* 允许跨域 */
changeOrigin: true,

}
}
}
}
};
