[JavaScript知识库]vue3-element-plus

1. 本地安装Vue3.0

npm init -y
npm i @vue/cli  # 安装脚手架

2. 项目搭建

npx vue create project  # 项目搭建,选择Vue3

3. 配置vue.config.js让项目运行的时候自动打开浏览器

// vue.config.js
module.exports = {
    devServer: {
        open: true // 自动打开浏览器
    }
}

4. 安装element-plus

cnpm install element-plus --save

// main.js
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
import locale from 'element-plus/es/locale/lang/zh-cn'

createApp(App).use(ElementPlus, {locale}).mount('#app')

去写菜单组件
安装axios,通过axios请求菜单数据

cnpm i -D axios

// main.js
import { createApp } from 'vue'
import App from './App.vue'
import ElementPlus from 'element-plus'
import 'element-plus/dist/index.css'
import locale from 'element-plus/es/locale/lang/zh-cn'
import axios from 'axios'

const app = createApp(App)
app.config.globalProperties.$http = axios

// createApp(App).use(ElementPlus, {locale}).mount('#app')
app.use(ElementPlus, {locale}).mount('#app')
