import { createRouter, createWebHistory } from "vue-router"
import type { RouteRecordRaw } from "vue-router"

const routes: Array<RouteRecordRaw> = [
  {
    path: "/",
    component: () => import("../components/footer.vue"),
    // 嵌套路由，可以无限嵌套
    children: [
      {
        // path为空即默认展示该路由
        path: "",
        name: "Login",
        component: () => import("../components/login.vue")
      },
      {
        path: "reg",
        name: "Reg",
        component: () => import("../components/reg.vue")
      }
    ]
  },
]

const router = createRouter({
  // 路由的模式
  history: createWebHistory(),
  // 路由信息
  routes
})

export default router
