Vite+Vue3安装且自动按需引入Element Plus组件库

一，安装Element Plus

npm install element-plus  //node环境16+

---

二，安装插件

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

---

三，配置vite.config.ts文件

//按需引入element-plus组件
import AutoImport from 'unplugin-auto-import/vite'
import Components from 'unplugin-vue-components/vite'
import { ElementPlusResolver } from 'unplugin-vue-components/resolvers'
export default defineConfig({plugins: [vue(),// 按需引入elementAutoImport({resolvers: [ElementPlusResolver()],}),Components({resolvers: [ElementPlusResolver()],}),],
})

---

四，使用icon图标需要单独安装

npm install @element-plus/icons-vue

---

五，main.ts注册icon

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'// 导入 element-plus 图标
import * as ElementPlusIconsVue from "@element-plus/icons-vue";const app = createApp(App)
app.use(router)
app.mount('#app')// 注册所有图标
for (const [key, component] of Object.entries(ElementPlusIconsVue)) {app.component(key, component);
}

六，使用组件

直接在vue页面模板上使用element标签即可
