GZIP压缩
GZIP压缩有动态跟静态两种
可以将由前端打包GZIP,通过 gzip_static:on会寻找以.gz结尾的文件，直接返回，不会占用cpu进行压缩，如果找不到则不进行压缩
nginx
gzip on|off;
gzip_min_length 1k;
gzip_comp_level 5;
gzip_types text/plain application/javascript application/x-javascript text/css application/xml text/javascript ;
gzip_static on|off
gzip_vary on;
gzip_buffers 2 4k;
gzip_http_version 1.1;
vue.config.js
const CompressionPlugin = require('compression-webpack-plugin')
configureWebpack: {
plugins: [
new CompressionPlugin({
algorithm: 'gzip',
test: /\.js$|\.html$|\.css$/,
filename: '[path].gz[query]',
minRatio: 1,
threshold: 10240,
deleteOriginalAssets: false,
}),
]
}
CDN
const isProd = process.env.NODE_ENV === 'production'
const cdn = {
externals: {
vue: 'Vue',
'vue-router': 'VueRouter',
vuex: 'Vuex',
axios: 'axios',
'ant-design-vue': 'antd',
'vue-ls': 'VueStorage',
},
css: [],
js: [
'//unpkg.com/vue@2.6.12/dist/vue.min.js',
'//unpkg.com/vue-router@3.4.9/dist/vue-router.min.js',
'//unpkg.com/vuex@3.5.1/dist/vuex.min.js',
'//unpkg.com/axios@0.21.0/dist/axios.min.js',
'//unpkg.com/ant-design-vue@1.7.2/dist/antd.min.js',
'//unpkg.com/vue-ls@3.2.1/dist/vue-ls.min.js',
]
};
configureWebpack: config => {
config.externals = isProd ? cdn.externals : {}
},
chainWebpack: config => {
config.plugin('html').tap(args => {
args[0].cdn = cdn
return args
})
}

路由按需加载
使用 ()=>import('xxx')按需加载路由组件,可以添加magic comments
打包后会单独生成chunk.[hash].js文件,进一步减小主包大小
{
path: '/login',
name: 'login',
component: () => import('@/views/login/Login'),
hidden: true,
},
