vue3+vite的路由配置

App.vue

添加router-view

<template>
  <div>
    <router-view></router-view>
  </div>
</template>

router/index.js

import { createRouter, createWebHistory} from 'vue-router'; // history
// createWebHashHistory hash

const routes = [
  {
    path: '/',
    name: 'index',
    component: () => import(/* webpackChunkName: 'importPage' */ '../views/index.vue') // 懒加载
  }
]
const router = createRouter({
  history: createWebHistory(),
  routes
});

export default router

main.js

引入App.vue、router/index.js

import { createApp } from 'vue'
import './style.css'
import App from './App.vue'
import router from './router/index'

// 创建应用 将配置对象传进去 挂载
const app = createApp(App)
app.use(router)
app.mount('#app')
