1.安装npm i compression-webpack-plugin
2. 复制一下代码到文件vue.comfig.js
const path = require('path')
const CompressionWebpackPlugin = require('compression-webpack-plugin')
// const VueLoaderPlugin = require('vue-loader/lib/plugin')
const resolve = dir => {
return path.join(__dirname, dir)
}
const isProduction = process.env.NODE_ENV === 'production'
const plugins = []
if (isProduction) {
plugins.push(
new CompressionWebpackPlugin({
filename: '[path].gz[query]',
algorithm: 'gzip',
// test: /\.css$|\.ttf$|\.html$|\.svg$|\.json$|\.js$/,
test: /\.css$|\.ttf$|\.svg$|\.json$|\.js$/,
threshold: 0, // 只有大小大于该值的资源会被处理
minRatio: 0.8, // 只有压缩率小于这个值的资源才会被处理
deleteOriginalAssets: true// 删除原文件
})
)
}
module.exports = {
productionSourceMap: false,
// 如果你不需要使用eslint，把lintOnSave设为false即可
// lintOnSave: false,
devServer: {
overlay: {
warnings: true,
errors: true
}
},
chainWebpack: config => {
config.resolve.alias.set('@', resolve('src'))
// config.output.filename('[name].[hash].js').end()
config.plugins.delete('preload') // TODO: need test
config.plugins.delete('prefetch') // TODO: need test
config.module
.rule('vue')
.use('vue-loader')
.loader('vue-loader')
.tap(options => {
options.compilerOptions.preserveWhitespace = true
return options
})
.end()
config.entry('index').add('babel-polyfill')
config
.when(process.env.NODE_ENV !== 'development',
config => {
config
.plugin('ScriptExtHtmlWebpackPlugin')
.after('html')
.use('script-ext-html-webpack-plugin', [{
// `runtime` must same as runtimeChunk name. default is `runtime`
inline: /runtime\..*\.js$/
}])
.end()
config
.optimization.splitChunks({
chunks: 'all',
cacheGroups: {
libs: {
name: 'chunk-libs',
test: /[\\/]node_modules[\\/]/,
priority: 10,
chunks: 'initial' // only package third parties that are initially dependent
},
elementUI: {
name: 'chunk-elementUI', // split elementUI into a single package
priority: 20, // the weight needs to be larger than libs and app or it will be packaged into libs or app
test: /[\\/]node_modules[\\/]_?element-ui(.*)/ // in order to adapt to cnpm
},
commons: {
name: 'chunk-commons',
test: resolve('src/components'), // can customize your rules
minChunks: 3, // minimum common number
priority: 5,
reuseExistingChunk: true
}
}
})
config.optimization.runtimeChunk('single')
}
)
config.module
.rule('images')
.use('image-webpack-loader')
.loader('image-webpack-loader')
.options({
bypassOnDebug: true
})
.end()
},
configureWebpack: {
// plugins: []
}
}
3.在package.json配置
4.开始打包
npm run build
