What are common issues with React error boundaries?

What are common issues with React error boundaries?

Common issues include not catching errors in asynchronous code, not handling errors in nested components, and improper placement of error boundaries.

How can I ensure my error boundaries catch all errors?

To catch all errors, place error boundaries higher in the component tree and ensure they wrap all components that might throw errors.

Can error boundaries catch errors in event handlers?

No, error boundaries do not catch errors in event handlers. You need to use try-catch blocks for that.

What happens if an error boundary fails?

If an error boundary fails, it will not catch the error, and the entire component tree may unmount, leading to a blank screen.

Are there any best practices for using error boundaries?

Yes, best practices include using multiple error boundaries for different parts of your app and providing fallback UI for better user experience.
