Global Error Handling

Global error handling catches exceptions across frontend and backend using try-catch blocks and error boundaries, preventing crashes. Implement centralized error management at all layers—API calls, UI event handlers, and background tasks—to ensure your application recovers gracefully instead of failing.

Global error handling separates user-facing messages from internal technical details by catching exceptions and mapping them to clear, non-revealing feedback. Return appropriate HTTP status codes and descriptive messages that help users understand what went wrong without leaking sensitive system information.

Implement exponential backoff retry logic within your error handling strategy to manage transient failures from external services and API timeouts. Catch timeout exceptions and database failures separately, allowing your application to retry failed operations before returning an error to the user.

Yes, global error handling applies to all application layers—frontend UI event handling, backend API endpoints, and background tasks. Use specific exception types and centralized error boundaries to enforce consistent error management strategies across your entire system.

Graceful degradation in global error handling allows non-critical failures to degrade functionality without crashing the app. Catch exceptions in secondary features and log them securely while letting core functionality continue, maintaining user experience even when some features are unavailable.
