见文档https://vue-docs-next-zh-cn.netlify.app/guide/installation.html#%E5%91%BD%E4%BB%A4%E8%A1%8C%E5%B7%A5%E5%85%B7-cli
vite搭建:
1. 安装vite npm init @vitejs/app 2. npm init vite <project-name> 3. cd <project-name> 4. npm i 5. npm run dev
vite引入组件时需要加文件后缀不然报错
路由配置
下载路由: npm install vue-router@4
1. 新建router文件夹,其下建index.js
import {createRouter, createWebHashHistory, createWebHistory} from "vue-router" const routes = [ { path: "/", component: () => import('../components/home.vue') }, { path: "/about", component: () => import('../components/pages/about.vue') }, ]; const router = createRouter({ // 4. 采用hash 模式 history: createWebHashHistory(), // 采用 history 模式 history: createWebHistory(), routes, }); export default router
2. 挂载到main.js
import { createApp } from 'vue' import App from './App.vue' import router from './router/index' // createApp(App).mount('#app') const app = createApp(App) app.use(router) app.mount('#app')
1. 调用挂在vue实例区别
//vue2 //main.js全局引入 import axios from 'axios' Vue.prototype.$axios = axios //在组件中使用通过this.$axios调用
//vue3 //main.js import axios from 'axios' import * as echarts from 'echarts' app.config.globalProperties.$http = axios app.config.globalProperties.$echarts = echarts //再别的组件中使用 const { proxy } = getCurrentInstance() let chart1 = proxy.$echarts.init(chartDom);
