How can I log errors in a React application?
You can use the componentDidCatch
lifecycle method to catch errors in class components, or the ErrorBoundary
component for functional components.
What is an Error Boundary?
An Error Boundary is a React component that catches JavaScript errors in its child component tree, logs those errors, and displays a fallback UI.
Can I log errors to an external service?
Yes, you can log errors to external services like Sentry or LogRocket by integrating their SDKs into your application.
How do I implement an Error Boundary?
You can create a class component that implements componentDidCatch
and getDerivedStateFromError
