一. 使用 CDN 加速
index.html 页面引入 cdn script
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width,initial-scale=1.0">
<link rel="icon" href="<%= BASE_URL %>favicon.ico">
<title>AI Finance</title>
</head>
<body>
<noscript>
<strong>We're sorry but yarn-frotend-cli3 doesn't work properly without JavaScript enabled. Please enable it to
continue.</strong>
</noscript>
<div id="app"></div>
<!-- built files will be auto injected -->
<script src="https://cdn.bootcss.com/vue/2.5.21/vue.min.js"></script>
<script src="https://cdn.bootcss.com/vuex/3.0.1/vuex.min.js"></script>
<script src="https://cdn.bootcss.com/vue-router/3.0.2/vue-router.min.js"></script>
<script src="https://cdn.bootcss.com/axios/0.18.0/axios.min.js"></script>
</body>
</html>
项目根目录下的 vue.config.js 添加 externals 配置,把引入的 cdn 库这这里配置后, yarn builid 就不会把这些库打包了
module.exports = {
configureWebpack: (config) => {
config.externals = {
vue: 'Vue',
vuex: 'Vuex',
'vue-router': 'VueRouter',
'axios': 'axios'
}
...
二. 启用 Gzip 压缩
Vue 项目默认不启动 Gzip 压缩, 需要安装 compression-webpack-plugin 包, 配置 config 文件.
yarn add compression-webpack-plugin
vue.config.js 配置文件中添加 configureWebpack 设置, 如下
const CompressionWebpackPlugin = require('compression-webpack-plugin')
const productionGzipExtensions = ['js', 'css']
configureWebpack: {
plugins: [
new CompressionWebpackPlugin({
filename: '[path].gz[query]',
algorithm: 'gzip',
test: new RegExp('\\.(' + productionGzipExtensions.join('|') + ')$'),
threshold: 10240,
minRatio: 0.8
})
]
}
注意 filename: '[path].gz[query]', 这一行, 这里的 compression-webpack-plugin 版本为 2.0 , 如果 compression-webpack-plugin 版本为 1.0 ,需要把 filename 参数换成 asset
Node服务添加 gzip 支持
npm i express compression
let express = require('express')
let app = express()
let compression = require('compression')
app.use(compression())
Nginx 服务添加 gzip 支持
http {
gzip on;
gzip_static on;
gzip_min_length 1024;
gzip_buffers 4 16k;
gzip_comp_level 2;
gzip_types text/plain application/javascript application/x-javascript text/css application/xml text/javascript application/x-httpd-php application/vnd.ms-fontobject font/ttf font/opentype font/x-woff image/svg+xml;
gzip_vary off;
gzip_disable "MSIE [1-6]\.";
}
使用 UglifyJsPlugin 压缩代码
yarn add uglifyjs-webpack-plugin
vue.config.js 中添加配置
const UglifyJsPlugin = require('uglifyjs-webpack-plugin')
module.exports = {
configureWebpack: (config) => {
config.plugins.push(new UglifyJsPlugin({
uglifyOptions: {
compress: {
warnings: false,
drop_debugger: true,
drop_console: true
}
},
sourceMap: false,
parallel: true
}))
}
}
