How can I use Suspense with React Router v6?

You can use React's Suspense to handle loading states in your routes. Wrap your routes in a <Suspense> component.

Can you show me a code example?

Sure! Here's a simple example:

import { Suspense, lazy } from 'react';
import { BrowserRouter as Router, Routes, Route } from 'react-router-dom';

const Home = lazy(() => import('./Home'));
const About = lazy(() => import('./About'));

function App() {
  return (
    <Router>
      <Suspense fallback={<div>Loading...</div>}>
        <Routes>
          <Route path='/' element={<Home />} />
          <Route path='/about' element={<About />} />
        </Routes>
      </Suspense>
    </Router>
  );
}

This will show a loading message while the components are being loaded.

What happens if I don't use Suspense?

If you don't use Suspense, your application won't handle loading states gracefully. Users might see a blank screen or incomplete UI while the components are loading.

Are there any performance benefits?

Yes, using Suspense can improve performance by allowing you to load components only when needed, reducing the initial load time.
