vue3+vite中再也不用单独页面引入vue了，神器：unplugin-vue-components/vite

前言：

        你是否还在为vue3项目中每个组件都需要单独引入vue而烦恼着，实际vite有一个插件能很好的解决这个问题，那就是 unplugin-auto-import/vite

使用步骤：

1、安装 npm/cnpm/pnpm/yarn  都可以，装上下面两个插件

unplugin-auto-import/vite

2、vite.config.js中配置

import AutoImport from 'unplugin-auto-import/vite';// 自动导入vue中hook reactive ref等
const config = {
    plugins: [
        AutoImport({
          //安装两行后你会发现在组件中不用再导入ref，reactive等
          imports: ['vue', 'vue-router','@vueuse/core'],
          //存放的位置
          dts: 'src/types/auto-import.d.ts',
        }),
    ]
    
}

3、页面上试试，发现是可以的

4、types下的auto-import.d.ts，自动生成

/* eslint-disable */
/* prettier-ignore */
// @ts-nocheck
// noinspection JSUnusedGlobalSymbols
// Generated by unplugin-auto-import
export {}
