vue-cli 3.x 已经没有了webpack.config.js文件。取而代之的是创建一个vue.config.js文件。官网是这样介绍的
vue.config.js
const path = require("path");
const resolve = dir => path.join(__dirname, dir);
//用于生产环境去除多余的css
const PurgecssPlugin = require("purgecss-webpack-plugin");
//全局文件路径
const glob = require("glob-all");
//压缩代码并去掉console
const UglifyJsPlugin = require("uglifyjs-webpack-plugin");
//代码打包zip
const CompressionWebpackPlugin = require("compression-webpack-plugin");
const productionGzipExtensions = /.(js|css|json|txt|html|ico|svg)(?.*)?$/i;
module.exports = {
// 废弃baseUrl 一般运维会配置好的
publicPath: process.env.NODE_ENV === "production" ? "/configtest/" : "/",
//打包的输出目录
outputDir: "dist/configtest",
//保存是校验
lintOnSave: true,
//如果文件等设置
pages: {
index: {
entry: "src/main.js",
template: "public/index.html",
filename: "index.html"
}
},
//静态资源打包路径
assetsDir: "static",
//默认false 可以加快打包
productionSourceMap: false,
//打包后的启动文件
indexPath: "congfigtest.html",
//打包文件是否使用hash
filenameHashing: true,
runtimeCompiler: false,
transpileDependencies: [],
//打包的css路径及命名
css: {
modules: false,
//vue 文件中修改css 不生效 注释掉 extract:true
extract: {
filename: "style/[name].[hash:8].css",
chunkFilename: "style/[name].[hash:8].css"
},
sourceMap: false,
loaderOptions: {
css: {},
less: {
// 向全局less样式传入共享的全局变量
// data: `@import "~assets/less/variables.less";$src: "${process.env.VUE_APP_SRC}";`
},
// postcss 设置
postcss: {
plugins: [
require("postcss-px-to-viewport")({
viewportWidth: 750, // 视窗的宽度，对应的是我们设计稿的宽度，一般是750
viewportHeight: 1334, // 视窗的高度，根据750设备的宽度来指定，一般指定1334，也可以不配置
unitPrecision: 3, // 指定`px`转换为视窗单位值的小数位数（很多时候无法整除）
viewportUnit: "vw", // 指定需要转换成的视窗单位，建议使用vw
selectorBlackList: [".ignore", ".hairlines"], // 指定不转换为视窗单位的类，可以自定义，可以无限添加,建议定义一至两个通用的类名
minPixelValue: 1, // 小于或等于`1px`不转换为视窗单位，你也可以设置为你想要的值
mediaQuery: false // 允许在媒体查询中转换`px`
})
]
}
}
},
//webpack 链式配置 默认已经配置好了 node_moudles/@vue
chainWebpack: config => {
// 修复HMR
config.resolve.symlinks(true);
// 修复Lazy loading routes 按需加载的问题，如果没有配置按需加载不需要写，会报错
// config.plugin("html").tap(args => {
// args[0].chunksSortMode = "none";
// return args;
// });
//添加别名
config.resolve.alias
.set("@", resolve("src"))
.set("assets", resolve("src/assets"))
.set("components", resolve("src/components"))
.set("layout", resolve("src/layout"))
.set("base", resolve("src/base"))
.set("static", resolve("src/static"));
// 压缩图片

.rule("images")
