Do Error Boundaries catch errors in event handlers or async code?

No, native Error Boundaries only catch errors during rendering, in lifecycle methods, and in constructors. For event handlers or async code, you should use try/catch blocks or the showBoundary hook to manually trigger a boundary.

How does React 19 improve error handling?

React 19 introduces options in createRoot such as onCaughtError, onUncaughtError, and onRecoverableError, which allow for centralized error logging and better observability of the application's health.

What is the benefit of granular error boundaries?

Placing boundaries around specific features (like a sidebar or a widget) rather than the whole app ensures that if one part fails, the rest of the application remains functional for the user.

Can I use hooks to create a React Error Boundary?

Native React Error Boundaries must be class components because they require the getDerivedStateFromError or componentDidCatch lifecycle methods. However, you can use the react-error-boundary library to interact with boundaries using hooks.

Security & Testing

Implements resilient React error handling patterns using error boundaries, fallback UIs, and recovery mechanisms to prevent application crashes.

This skill provides comprehensive guidance and implementation patterns for React Error Boundaries, ensuring web applications handle runtime errors gracefully. It covers both native class-based implementations and the react-error-boundary library, offering specialized strategies for async error propagation and modern React 19 createRoot hooks. By emphasizing granular boundary placement and accessible fallback UIs with retry functionality, it helps developers build robust frontend architectures that isolate failures and maintain a seamless user experience even when individual components fail.
