Vue Error Handling vs React

What are the main differences in error handling between Vue and React?

In Vue, error handling is often done using the errorCaptured lifecycle hook, while React uses error boundaries. Vue's approach allows for centralized error handling in components, whereas React's error boundaries can catch errors in the rendering phase.

Can you give an example of how to implement error handling in both frameworks?

Sure! In Vue, you can use the errorCaptured hook like this:

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

In React, you would create an error boundary like this:

class ErrorBoundary extends React.Component {
  componentDidCatch(error, info) {
    console.error('Error:', error);
  }

  render() {
    return this.props.children;
  }
}

What are the advantages of using error boundaries in React?

Error boundaries in React provide a way to catch JavaScript errors in the component tree, allowing you to display a fallback UI instead of crashing the whole app. This improves user experience and helps in debugging.

Is there a way to log errors in both frameworks?

Yes! In Vue, you can log errors in the errorCaptured hook. In React, you can log errors in the componentDidCatch method of your error boundary. Both methods allow you to send error information to a logging service.
