Vue3 引入Element-Plus组件库vue-cli按需自动引入+引入ElementPlus的Icon图标

一：引入Element-Plus组件库vue-cli按需自动引入

1.使用包管理器（如 NPM、Yarn ）安装 Element Plus

# NPM
$ npm install element-plus --save

# Yarn
$ yarn add element-plus

2.首先要安装两款插件 unplugin-vue-components 和 unplugin-auto-import：

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

# Yarn
$ yarn add -D unplugin-vue-components unplugin-auto-import

3.在vue.config.js加入plugins代码如下

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

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

4.在vue页面加入如下，测试是否引入成功

<template>
  <div>
    <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>
  </div>
</template>

5.重新启动运行项目，然后预览浏览器截图如下

二：引入elementPlus的Icon图标

1.在项目终端运行

# NPM
$ npm install unplugin-icons -D

# Yarn
$ yarn add unplugin-icons -D

2.在main.ts全量引入Icon图标

import * as ElementPlusIconsVue from "@element-plus/icons-vue";

const app = createApp(App);

for (const [key, component] of Object.entries(ElementPlusIconsVue)) {
    
    
  app.component(key, component);
}
app.mount("#app");

3.在vue页面使用

 <el-icon><Expand /></el-icon>
