如何使用react-router创建侧边栏和设置按钮样式

npm install react-router-dom

import { BrowserRouter as Router, Route, Link } from 'react-router-dom';

const Sidebar = () => {
  return (
    <div>
      <ul>
        <li>
          <Link to="/">首页</Link>
        </li>
        <li>
          <Link to="/设置">设置</Link>
        </li>
      </ul>
    </div>
  );
};

const MainContent = () => {
  return (
    <div>
      <Route exact path="/" component={Home} />
      <Route path="/设置" component={Settings} />
    </div>
  );
};

const App = () => {
  return (
    <Router>
      <div>
        <Sidebar />
        <MainContent />
      </div>
    </Router>
  );
};
