vue.config.js

const CompressionWebpackPlugin = require('compression-webpack-plugin');module.exports = {configureWebpack: config => {if (process.env.UNI_PLATFORM === 'h5') {filePath = 'static/js/'; //打包文件存放文件夹路径Timestamp = '.' + new Date().getTime(); //时间戳}config.plugins.push(new CompressionWebpackPlugin({filename: "[path][base].gz",algorithm: "gzip",test: /\.js$/,threshold: 10240,minRatio: 0.8,exclude: /node_modules/,}));},chainWebpack: config => {//通过运行 vue inspect plugins 的值html插件别名。。  config.plugin('html-index').tap(args => {args[0].minify = {removeAttributeQuotes: false}return args})config.when(process.env.NODE_ENV === "production", config => {config.plugin('html-index').tap(args => {args[0].minify = {removeAttributeQuotes: false}return args})config.output.filename("static/js/[name]-[contenthash].js");config.output.chunkFilename("static/js/[id]-[chunkhash].js");config.optimization.splitChunks({name: false, //官方建议在生产环境时将 name 设置为 false，为了“it doesn't change names unnecessarily”hidePathInfo: true,})})},
}

这样打包出来的文件名就会短很多,且会打包压缩出gz文件.
