vue3集成Element-plus实现按需自动引入组件的方法总结

npm install element-plus

import { createApp } from 'vue'
// 全局引入
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
import App from './App.vue'
import router from './router'
import store from './store'
 
const app = createApp(App)
app.use(router)
app.use(store)
app.use(ElementPlus)
app.mount('#app')

<template>
  <div class="app">
    <el-button>Default</el-button>
    <el-button type="primary">Primary</el-button>
    <el-button type="success">Success</el-button>
    <el-button type="info">Info</el-button>
    <el-button type="warning">Warning</el-button>
    <el-button type="danger">Danger</el-button>
    <el-button>中文</el-button>
  </div>
</template>
<script lang="ts">
import { defineComponent } from 'vue'
// 局部引入
import { ElButton } from 'element-plus'
import 'element-plus/theme-chalk/el-button.css'
import 'element-plus/theme-chalk/base.css'
export default defineComponent({
  components: { ElButton },
  setup() {
    return {}
  }
})
</script>
 
<style lang="less"></style>

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

// vue.config.js
const AutoImport = require('unplugin-auto-import/webpack')
const Components = require('unplugin-vue-components/webpack')
const { ElementPlusResolver } = require('unplugin-vue-components/resolvers')
module.exports = {
  outputDir: './build',
  // 和webpapck属性完全一致，最后会进行合并
  configureWebpack: {
    resolve: {
      alias: {
        components: '@/components'
      }
    },
    //配置webpack自动按需引入element-plus，
      plugins: [
        AutoImport({
          resolvers: [ElementPlusResolver()]
        }),
        Components({
          resolvers: [ElementPlusResolver()]
        })
      ]
  }
}
