Error Handling Patterns

Next.js and React error handling uses error boundaries for UI fallbacks and route-level error pages for graceful degradation. This framework provides custom error classes, API error standardization, and retry mechanisms to maintain application stability during failures.

Standardizing API error responses in TypeScript requires defining custom error hierarchies with specific codes and HTTP status codes. This approach distinguishes operational errors from internal errors to ensure consistent API error management across routes.

React error boundaries catch component tree errors and display fallback UI instead of crashing. This framework provides a reusable error boundary component to wrap your application content, log errors with context, and show user-friendly messages.

Retry logic for transient network errors is supported through resilience patterns that automatically retry failed API requests. This approach enhances application resilience and improves user experience during temporary network disruptions.

Logging errors with context in TypeScript involves capturing custom error class details and application state during failures. This framework provides structured logging patterns that integrate with error boundaries and API routes for actionable diagnostics.

This error handling framework operates without external dependencies, providing native TypeScript patterns and React component implementations. It covers error boundaries, API standardization, and retry mechanisms using built-in language features.
