What are error boundaries in Vue components?

What are error boundaries in Vue components?

Error boundaries are special components in Vue that catch JavaScript errors in their child components, preventing the entire app from crashing.

How do I implement error boundaries in my Vue app?

You can create an error boundary by defining a component with the errorCaptured lifecycle hook to handle errors.

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

Sure! Here's a simple example:

export default {
  errorCaptured(err, vm, info) {
    console.error('Error captured:', err);
    return false; // Prevents the error from propagating further
  }
};

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

If an error occurs outside of an error boundary, it will not be caught, and the entire Vue app may crash.
