dev-error-handling

Error handling middleware in Node.js catches both known and unexpected runtime errors to manage server responses. It integrates with Express to intercept failures, log details, and return structured error responses for application stability.

Client-side error boundaries catch and display React UI rendering errors gracefully during component rendering. They intercept failures in the component tree to prevent full application crashes and show informative user feedback.

Custom error classes define a hierarchy of error types for precise API error identification and handling. They allow developers to categorize exceptions distinctly, enabling targeted failure detection and clearer server responses.

Retry mechanisms include patterns for retrying failed API operations to improve robustness against transient issues. They automatically reattempt failed requests, ensuring continuity and recovery during temporary network disruptions.

Yes, this approach handles both backend API errors and frontend React exceptions. It spans server error responses and client-side boundaries, addressing failure detection, logging, and recovery across the full application stack.
