基于element-ui的cdn打包，网上搜到的一些教程非常坑，总是不说关键的细节。
一、3.x
在build/webpack.base.conf.js下module.exports中添加打包排除
externals: {
'vue': 'Vue',
'vue-router': 'VueRouter',
'element-ui': 'element-ui'
},

index.html中body里<div id＝"app"></div>下面一刚加入，注意head中加入css样式cdn
<script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
<script src="https://cdn.bootcss.com/vue-router/3.1.3/vue-router.min.js"></script>
<!-- 引入组件库 用饿了吗官网提供的cdn也是比较慢的，建议自行换cdn-->
<script src="https://unpkg.com/element-ui/lib/index.js"></script>
main.js中

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
// import ElementUI from 'element-ui';
// import 'element-ui/lib/theme-chalk/index.css';
import App from './App'
import router from './router'
import Router from 'vue-router'
Vue.use(Router)
// Vue.use(ElementUI);
Vue.config.productionTip = false
const originalPush = Router.prototype.push
Router.prototype.push = function push(location) {
return originalPush.call(this, location).catch(err => err)
}
/* eslint-disable no-new */
new Vue({
el: '#app',
router,
components: { App },
template: '<App/>'
})
打包：
npm run build
二、4.x
先找到 vue.config.js(没有就创建-根目录下，可参考官网)， 添加 externals 让webpack 不打包 vue 和 element
module.exports = {
configureWebpack: config => {
config.externals = {
vue: "Vue",
"element-ui": "ELEMENT",
"vue-router": "VueRouter",
vuex: "Vuex",
axios: "axios"
};
},
chainWebpack: config => {
const cdn = {
// 访问https://unpkg.com/element-ui/lib/theme-chalk/index.css获取最新版本
css: ["//unpkg.com/element-ui@2.10.1/lib/theme-chalk/index.css"],
js: [
"//unpkg.com/vue@2.6.10/dist/vue.min.js", // 访问https://unpkg.com/vue/dist/vue.min.js获取最新版本
"//unpkg.com/vue-router@3.0.6/dist/vue-router.min.js",
"//unpkg.com/vuex@3.1.1/dist/vuex.min.js",
"//unpkg.com/axios@0.19.0/dist/axios.min.js",
"//unpkg.com/element-ui@2.10.1/lib/index.js"
]
};
// 如果使用多页面打包，使用vue inspect --plugins查看html是否在结果数组中
config.plugin("html").tap(args => {
// html中添加cdn
args[0].cdn = cdn;
return args;
});
}
};
然后在html中引入CDN加速即可
<!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><%= htmlWebpackPlugin.options.title %></title>
<!-- 使用CDN的CSS文件 -->
<% for (var i in htmlWebpackPlugin.options.cdn &&
htmlWebpackPlugin.options.cdn.css) { %>
<link rel="stylesheet" href="<%= htmlWebpackPlugin.options.cdn.css[i] %>" />
<% } %>
</head>
<body>
<noscript>
<strong>We're sorry but <%= htmlWebpackPlugin.options.title %> doesn't work properly without JavaScript enabled. Please enable it to continue.</strong>
</noscript>
<div id="app"></div>
<!-- 使用CDN的JS文件 -->
<% for (var i in htmlWebpackPlugin.options.cdn &&
htmlWebpackPlugin.options.cdn.js) { %>
<script
type="text/javascript"
src="<%= htmlWebpackPlugin.options.cdn.js[i] %>"
></script>
<% } %>
<!-- built files will be auto injected -->
</body>
</html>
三、其他
npm run build 失败一般是dist文件被占用
Nginx配置
server {
listen 80;
server_name lingkang.top www.lingkang.top;
location / {
try_files $uri $uri/ @router;
root /usr/local/docker/nginx/wwwroot;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Real-Port $remote_port;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
index index.html index.htm;
}
location @router {
rewrite ^.*$ /index.html last;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
}
nginx.conf开启gzip
gzip on;
gzip_min_length 1k;
gzip_buffers 4 16k;
gzip_comp_level 4;
gzip_types text/plain application/x-javascript text/css application/xml text/javascript application/x-httpd-php image/jpeg image/gif image/png;
gzip_vary off;
