戳这里，跳文档

二、使用步骤

1.安装插件

npm install -D unplugin-vue-components unplugin-auto-import

2.配置vue.config.js

vue-cli内部用的就是webpack，configureWebpack配置的会被合并

const AutoImport = require('unplugin-auto-import/webpack')
const Components = require('unplugin-vue-components/webpack')
const { ElementPlusResolver } = require('unplugin-vue-components/resolvers')

module.exports = {
  configureWebpack: {
    plugins: [
      AutoImport({
        resolvers: [ElementPlusResolver()]
      }),
      Components({
        resolvers: [ElementPlusResolver()]
      })
    ]
  }
}

3.测试

运行时，会自动生成auto-imports.d.ts文件导入组件
