3、cdn配置

安装插件
npm install vite-plugin-cdn-import --save-dev

导入
import importToCDN from "vite-plugin-cdn-import";
配置(以element-plus为例)
plugins: [
   ...
    importToCDN({
      modules: [
        {
          name: "vue",
          var: "Vue",
          path: `https://unpkg.com/vue@next`,
        },
        {
          name: "element-plus",
          var: "ElementPlus",
          path: `https://unpkg.com/element-plus`,
          css: `https://unpkg.com/element-plus/dist/index.css`,
        },
      ],
    }),
  ],
