1.下载依赖

npm i react-router-dom

2.配置文件  router/index.js

import { createBrowserRouter,Navigate } from'react-router-dom';
import main from '../pages/mian';
import home from '../pages/home/index';
const routes = [
  {
    path: '/',
    Component: main,
    children: [
      // 重定向
      {
        path: '/',
        element: <Navigate to="home" replace />
      },
      {
        path: '/home',
        Component: home
      }
    ]
  }
]


export default createBrowserRouter(routes)

3.创建文件   pages/mian.js

import React from "react";
import { Outlet } from "react-router-dom";
const main = () => {
  return (
    <div>
      <h1>Welcome to my React App!</h1>
      <p>This is the main component.</p>
      {/* 显示子文件位置 */}
      <Outlet />
    </div>
  );
}
export default main;

4.创建页面组件  pages/home/index.js

const home = () => {
  return (
    <div>
      <h1>Home Page</h1>
      <p>Welcome to the Home Page!</p>
    </div>
  );
}
export default home

5.在入口文件App.js导入router

import { RouterProvider } from 'react-router-dom';
import router from './router'
function App() {
  return (
    <div className='app'>
      <RouterProvider router={router}></RouterProvider>
    </div>
  );
}

export default App;

6.使用方法
