How can I handle errors in React Router using error boundaries?

You can use error boundaries in React to catch errors in your components. Wrap your routes with an error boundary component.

Can you show me a code example of how to implement an error boundary?

Sure! Here's a simple example:

class ErrorBoundary extends React.Component {
  constructor(props) {
    super(props);
    this.state = { hasError: false };
  }

  static getDerivedStateFromError(error) {
    return { hasError: true };
  }

  componentDidCatch(error, info) {
    console.error('Error caught in ErrorBoundary:', error);
  }

  render() {
    if (this.state.hasError) {
      return <h1>Something went wrong.</h1>;
    }
    return this.props.children;
  }
}

You can then use this ErrorBoundary to wrap your routes.

What happens if an error occurs outside of the error boundary?

If an error occurs outside of the error boundary, it won't be caught by that boundary. You may need to implement additional error handling strategies.

Are there any limitations to using error boundaries?

Yes, error boundaries only catch errors in the components they wrap. They do not catch errors in event handlers, asynchronous code, or server-side rendering.
