React Error Boundaries

React Error Boundaries

Error boundaries are React components that catch JavaScript errors anywhere in their child component tree, log those errors, and display a fallback UI instead of crashing the entire application. They are implemented using React’s class components with lifecycle methods like getDerivedStateFromError and componentDidCatch.

How to Implement Error Boundaries in a React Application

To implement error boundaries, you need to follow these steps:

1. Create a class component that implements the getDerivedStateFromError and componentDidCatch methods.
2. Wrap the error-prone components within this boundary component.
3. Provide a fallback UI for displaying errors to the user.

Example: Implementing Error Boundaries

1. Create a new class component called ErrorBoundary.
2. Define the getDerivedStateFromError lifecycle method to update the state when an error occurs.
3. Use the componentDidCatch method to log the error information.
4. Render a fallback UI if an error is detected.
