An example of an AI chatbot conversation about error boundaries in React functional components.
How do error boundaries work in React functional components?
Error boundaries are React components that catch JavaScript errors in their child component tree. They help prevent crashes by displaying a fallback UI.
Can you show me an example of how to implement an error boundary?
Sure! You can create a class component that implements the componentDidCatch lifecycle method and getDerivedStateFromError static method.
Is it possible to use error boundaries with hooks?
Error boundaries can only be class components. However, you can use hooks within the components that are wrapped by error boundaries.
What happens if an error occurs in a functional component?
If an error occurs in a functional component, it will not be caught by error boundaries unless the functional component is wrapped in one.
