如何在React中使用路由？

npm install react-router-dom

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

const Home = () => <div>Home</div>;
const About = () => <div>About</div>;

const App = () => {
  return (
    <Router>
      <Switch>
        <Route exact path="/" component={Home} />
        <Route path="/about" component={About} />
      </Switch>
    </Router>
  );
};

ReactDOM.render(<App />, document.getElementById('root'));
