问题描述：vue3 新增路由对象或者是属性类型后，会报错
原因：vue3源码里没有定义这个属性
解决方法：新增一个路由声明文件，扩展基础路由对象属性

比如新增一个hidden false,报错如下
TS2322: Type ‘{ path: string; name: string; hidden: false; component: () => Promise<typeof import("*.vue")>; }’ is not assignable to type ‘RouteRecordRaw’. Object literal may only specify known properties, and ‘hidden’ does not exist in type ‘RouteRecordSingleView’.

解决方法1：将hidden 直接放在meta里

const routes: Array<RouteRecordRaw> = [
    {
        path: '/',
        redirect: '/login',
    },
    {
        path: '/login',
        name:'login',
        meta:{
            hidden: false
        },
        component: () => import('@/views/login.vue'), // 懒加载组件
    }
 ]

解决方法2：引入 _RouteRecordBase ， 定义 hidden

import {
    createRouter,
    createWebHashHistory,
    RouteRecordRaw,
    _RouteRecordBase 
} from 'vue-router'

declare module 'vue-router'{
    interface _RouteRecordBase {
        hidden?: boolean | string | number
    }
}

const routes: Array<RouteRecordRaw> = [
 {
        path: '/',
        redirect: '/login',
    },
    {
        path: '/login',
        name:'login',
       	hidden: false,
        component: () => import('@/views/login.vue'), // 懒加载组件
    }
]
