1、安装  

pnpm i vue-router

2、新建文件：src/routes.ts

import { RouteRecordRaw } from 'vue-router'

export const constantRoute: RouteRecordRaw[] = [
  {
    //
    path: '/',
    redirect: '/login',
  },
  {
    //
    path: '/login',
    component: () => import('@/views/Login/index.vue'),
    name: 'Login',
    meta: {
      title: '登录',
    },
  },
  {
    //登录成功展示数据的页面 main.vue
    path: '/layout',
    component: () => import('@/layout/index.vue'),
    name: 'layout',
    meta: {
      title: 'layout',
    },
  },
  {
    path: '/404',
    component: () => import('@/views/404/index.vue'),
    name: '404',
    meta: {
      title: '404',
    },
  },
  {
    // 任意路由(无效或者不存在的路径 跳转至404)
    path: '/:pathMatch(.*)*',
    component: () => import('@/views/404/index.vue'),
    name: 'Any',
    meta: {
      title: '任意',
    },
  },
]

3、新建文件：src/index.ts

import { createRouter, createWebHashHistory } from 'vue-router'
import { constantRoute } from './routes'
const router = createRouter({
  history: createWebHashHistory(),
  routes: constantRoute,
  //   滚动行为
  scrollBehavior() {
    // ...
    return {
      left: 0,
      top: 0,
    }
  },
})

export const setupRouter = (app: any) => {
    app.use(router)
  }
export default router

4、main.ts 引入

// 路由
import { setupRouter } from './router'
// 创建实例
const setupAll = async () => {
  const app = createApp(App)
  await setupRouter(app)
  app.mount('#app')
}

setupAll()

5、app.vue 中加入代码

以上完成 ，输入不同路径就可以跳转到对应页面了。
