How can I handle routing errors in React 18?

In React 18, you can handle routing errors by using the ErrorBoundary component. This allows you to catch errors in your routing logic.

Can you show me an example of using ErrorBoundary?

Sure! Here's a simple example:

import { ErrorBoundary } from 'react-error-boundary';

function MyComponent() {
  return (
    <ErrorBoundary FallbackComponent={ErrorFallback}>
      <MyRoutes />
    </ErrorBoundary>
  );
}

function ErrorFallback({ error }) {
  return <div>Something went wrong: {error.message}</div>;
}

This will catch any errors in MyRoutes and display the fallback UI.

What if I want to log the errors as well?

You can use the onError prop of ErrorBoundary to log errors. For example:

<ErrorBoundary
  FallbackComponent={ErrorFallback}
  onError={(error) => console.error('Error caught:', error)}
>
  <MyRoutes />
</ErrorBoundary>

Thanks! Is there a way to redirect users after an error?

Yes, you can use the useNavigate hook from react-router-dom inside your ErrorFallback component to redirect users after an error.
