high-cdn-webpack-plugin是Webpack一款插件，用来在index.html引用的CDN服务器宕机后自动替换CDN地址，实现CDN高可用的服务状态，需要配合html-webpack-plugin生成的模板html动态注入。

使用后：

二、插件使用

1. 安装

npm install high-cdn-webpack-plugin --save

2. 使用

确定模板文件中存在标签，否则插件无法正常找到脚本插入点：

<!DOCTYPE html>
<html lang="en">
<head> <!-- 存在head标签才能使用 -->
    <meta charset="UTF-8">
    <title>hello world</title>
</head>
<body>
   
</body>
</html>

引入插件，并实例化：

// webpack.config.js

const HighCdnWebpackPlugin = require("high-cdn-webpack-plugin");

module.exports = {
  // ... 省略其他配置
  plugins: [
    // ... 省略其他插件
    new HighCdnWebpackPlugin({
      template: 'index.html',
      js: [
        {
          external: {
            'vue': 'Vue'
          },
          path: 'https://cdn.staticfile.org/vue/2.5.16/vue.min.js',
          replacementPath: '/vue/3.0.11/vue.cjs.min.js'
        },
        {
          external: {
            'vue-router': 'VueRouter',
          },
          path: 'https://cdn.staticfile.org/vue-router/3.0.1/vue-router2.min.js',
          replacementPath: '/vue-router/4.0.6/vue-router.cjs.js'
        },
      ],
      css: ['https://cdn.bootcdn.net/ajax/libs/element-ui/2.15.1/theme-chalk/index.min.css']
  })  
  ]
}

三、Vuejs 使用

// vue.config.js

const HighCdnWebpackPlugin = require("high-cdn-webpack-plugin");
module.exports = {
  // ... 省略其他配置
  configureWebpack: {
    plugins: [
      // ... 省略其他插件
      new HighCdnWebpackPlugin()  
    ]
  }
}

四、其他

Options

属性	类型	必填	说明
template	String	N	打包目录下模板文件名称，默认为index.html
css	Array	N	Css cdn地址，css暂不支持高可用
js	Array	Y	Js文件cdn地址，格式如下方

    {
          external: {   // CDN module export 声明
            'vue': 'Vue'
          },
          path: 'https://cdn.staticfile.org/vue/2.5.16/vue.min.js', // CDN地址
          replacementPath: 'https://cdn.bootcdn.net/ajax/libs/vue/3.0.11/vue.cjs.min.js' // path CDN失效后，将用此个地方的地址代替，一般使用自己服务器上的静态文件地址
