创建一个简单的react router demo

import React from 'react';
import ReactDOM from 'react-dom/client';
import './index.css';
import App from './App';
import reportWebVitals from './reportWebVitals';
import { createBrowserRouter, RouterProvider } from 'react-router-dom';

// 1. 创建router实例对象并且配置路由对应关系
const router = createBrowserRouter([
  {
    path: '/login',
    element: <div>This is the login page.</div>
  },
  {
    path: '/article',
    element: <div>This is the article page.</div>
  }
])


const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <React.StrictMode>
    {/* 2. 路由绑定 */}
    <RouterProvider router={router}></RouterProvider>
  </React.StrictMode>
);

// If you want to start measuring performance in your app, pass a function
// to log results (for example: reportWebVitals(console.log))
// or send to an analytics endpoint. Learn more: https://bit.ly/CRA-vitals
reportWebVitals();
