[See how to mi By default, if your application throws an error during rendering, React will remove its UI from the screen. To prevent this, you can wrap a part of your UI into an *Error Boundary*. An Error Boundary is a special component that lets you display some fallback UI instead of the part that crashed--for example, an error message. + +Error boundaries do not catch errors for: + +- Event handlers [(learn more)](/learn/responding-to-events) +- [Server side rendering](/reference/react-dom/server) +- Errors thrown in the error boundary itself (rather than its children) +- Asynchronous code (e.g. `setTimeout` or `requestAnimationFrame` callbacks); an exception is the usage of the [`startTransition`](/reference/react/useTransition#starttransition) function returned by the [`useTransition`](/reference/react/useTransition) Hook. Errors thrown inside the transition function are caught by error boundaries [(learn more)](/reference/react/useTransition#displaying-an-error-to-users-with-error-boundary) + + + To implement an Error Boundary component, you need to provide [`static getDerivedStateFromError`](#static-getderivedstatefromerror) which lets you update state in response to an error and display an error message to the user. You can also optionally implement [`componentDidCatch`](#componentdidcatch) to add some extra logic, for example, to log the error to an analytics service. With [`captureOwnerStack`](/reference/react/captureOwnerStack) you can include the Owner Stack during development.
