How can I handle errors in React Router v6?

In React Router v6, you can handle errors by using the ErrorBoundary component. This allows you to catch errors in your routes.

Can you show me an example of using ErrorBoundary?

Sure! You can create an ErrorBoundary component and wrap your routes with it. Here's a simple example:

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

function MyErrorBoundary({ children }) {
  return (
    <ErrorBoundary FallbackComponent={ErrorFallback}>
      {children}
    </ErrorBoundary>
  );
}

function App() {
  return (
    <MyErrorBoundary>
      <Routes>
        <Route path="/somepath" element={<SomeComponent />} />
      </Routes>
    </MyErrorBoundary>
  );
}

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

What should I include in the fallback UI?

In the fallback UI, you can include a message to inform users that something went wrong, and possibly a button to retry or go back. For example:

function ErrorFallback({ error }) {
  return (
    <div>
      <h2>Something went wrong:</h2>
      <pre>{error.message}</pre>
      <button onClick={() => window.location.reload()}>Retry</button>
    </div>
  );
}
