An example of an AI chatbot conversation about error boundaries in React.
What are error boundaries in React?
Error boundaries are React components that catch JavaScript errors in their child component tree, log those errors, and display a fallback UI.
How do I implement an error boundary in my React app?
You can create an error boundary by defining a class component that implements either the static getDerivedStateFromError method or the componentDidCatch lifecycle method.
Can error boundaries catch errors in asynchronous code?
No, error boundaries only catch errors in the rendering phase, lifecycle methods, and constructors of the whole tree below them.
What happens if an error occurs outside of an error boundary?
If an error occurs outside of an error boundary, it will crash the entire React application.
