vue3多端适配两套代码

1.配置路由router 下的index文件

import { createRouter, createWebHistory } from 'vue-router';
const routePC = [
  {
    path: '/',
    name: 'index',
    component: ()=> import('@/pages/PC/index/IndexView.vue')
  },
];
const routesM = [
  {
    path: '/',
    name: 'index',
    component: ()=> import('@/pages/Mobile/index/IndexView.vue')
  },
];
var routes =[]

  let flag = navigator.userAgent.match(
    /(phone|pad|pod|iPhone|iPod|ios|iPad|Android|Mobile|BlackBerry|IEMobile|MQQBrowser|JUC|Fennec|wOSBrowser|BrowserNG|WebOS|Symbian|Windows Phone)/i
  );
  // 这里判断后选择使用移动端的路由还是pc端的路由
  if(flag){
    routes = routesM
    
  }else{
    routes = routePC
  }
const router = createRouter({
  history: createWebHistory(import.meta.env.BASE_URL),
  
  fallback: false,
   
   routes
});
export default router;

2.页面代码配置两套，放进不同的文件夹
