How can I customize the fallback UI in my React application?

You can customize the fallback UI by creating a new component and using it in your error boundary.

What should I include in my fallback UI?

Include user-friendly messages, a retry button, and possibly some visuals to enhance the experience.

Can you show me a code example?

Sure! Here's a simple example:

const FallbackUI = () => (
  <div>
    <h1>Something went wrong!</h1>
    <button onClick={() => window.location.reload()}>Retry</button>
  </div>
);

How do I implement this in my existing app?

Wrap your main component with an ErrorBoundary and pass the FallbackUI as a prop.
