What problem does it solve?
Prevents application crashes and poor user experiences caused by runtime errors, network failures, and unexpected or malformed data by providing patterns and components for graceful degradation and recovery.
Core Features & Use Cases
- Error boundaries & UI fallbacks: Isolate component errors and display recoverable fallback UIs without crashing the whole app.
- Data fallback & loading states: Use cache-first strategies, skeleton loaders, and stale-data warnings to keep interfaces responsive when network calls fail.
- Reliability controls: Implement retry with exponential backoff and circuit breakers for external services to improve availability and avoid cascading failures.
- Use case: Wrap a dashboard and critical user profile flows with ErrorBoundary, use a cached useUserData hook for offline fallback, and protect third-party API calls with retry and a circuit breaker.
Quick Start
Wrap critical pages and data fetches with an ErrorBoundary, implement a cache-first useUserData hook with skeletons, and add retry with exponential backoff plus a circuit breaker for external API calls.
