Use try-catch with async/await, implement proper error states, handle promise rejections, use error boundaries where applicable. Consider loading states and user feedback.
Place boundaries strategically to isolate failures, consider component hierarchy, implement granular error handling. Balance between too many and too few boundaries.
Use error boundaries around portals, handle portal-specific errors, manage cleanup on errors. Consider modal and overlay error scenarios.
Implement route-level error boundaries, handle navigation errors, provide error pages, manage route transitions. Consider deep linking errors.
Provide clear, actionable error messages, implement proper i18n, consider user experience, maintain consistency. Handle different error types appropriately.
Implement error tracking services, collect error metrics, analyze error patterns, set up alerts. Consider privacy and performance implications.
Wrap third-party components in error boundaries, handle integration errors, implement fallbacks. Consider version compatibility issues.
Test error boundaries, simulate different error conditions, verify error recovery, implement comprehensive test cases. Consider edge cases and error combinations.
Create a class component that implements either getDerivedStateFromError() or componentDidCatch() lifecycle methods. getDerivedStateFromError() renders fallback UI, while componentDidCatch() handles error logging.
Error Boundaries don't catch errors in event handlers, asynchronous code (setTimeout/requestAnimationFrame), server-side rendering, or errors thrown in the error boundary itself. These require different error handling approaches.
Implement retry logic, state reset mechanisms, fallback UI, and proper error clearing. Consider user experience and recovery workflows.
Implement client-side validation, handle server validation errors, provide clear error messages, manage error states properly. Consider UX and accessibility.
Implement error reducers, handle async action errors, provide error states in store, consider middleware for error handling. Handle global vs local error states.
Use try-catch blocks in event handlers, implement proper error handling and state updates, provide user feedback. Consider global error handling for uncaught errors in events.
Implement error handling logic in HOCs, wrap components with error boundaries, handle prop validation errors. Consider composition of error handling HOCs.
Implement field-level and form-level validation, handle async validation, provide immediate feedback. Consider UX and accessibility requirements.
Implement proper error states, handle network failures, manage retry logic, provide user feedback. Consider caching and offline scenarios.
Error Boundaries are React components that catch JavaScript errors in their child component tree and display fallback UI. They prevent the entire app from crashing and provide a way to gracefully handle runtime errors.
componentDidCatch captures error information and error stack traces. Used for error logging, analytics, and side effects in error handling. Cannot modify state during render phase.
Implement proper error status handling, retry mechanisms, offline detection, and user feedback. Consider caching strategies and fallback content.
Use try-catch in effects, implement error states, handle cleanup properly, consider custom hooks for error handling. Cannot use error boundaries directly in hooks.
Use Error Boundaries with Suspense, handle loading errors, implement fallback UI, manage timeout scenarios. Consider data fetching errors.
