Generates error boundaries and fallback UIs for React apps, with examples for both class-based boundaries and the react-error-boundary library. Includes Next.js-specific implementations for error.tsx, global-error.tsx, and not-found.tsx files in the App Router. Also covers async error handling patterns and error reporting integration stubs for services like Sentry. The resettable error boundary pattern is nice for letting users retry failed operations without a full page reload. Most useful when you're setting up error handling infrastructure in a new project or need to wrap third-party components that might throw. The code examples are production-ready and include proper TypeScript types throughout.
