Error Boundary Creator

Add resilient error handling to React and Next.js apps: error boundaries, fallback UIs, async error handling, and error reporting.

Workflow

Identify error-prone areas: async operations, third-party integrations, and route-level entry points.
Wrap components in an error boundary. Use a class boundary or the react-error-boundary library. See references/class-boundaries.md.
For Next.js App Router, add the relevant error.tsx, global-error.tsx, and not-found.tsx segment files. See references/nextjs-error-handling.md.
Handle errors that boundaries miss (event handlers, promises) and wire up reporting. See references/async-and-reporting.md.
Design fallback UIs with role="alert" and a recovery action (reset or reload).
Route caught errors to a single reporting sink and test error states before shipping.

references/class-boundaries.md — Basic, resettable, and react-error-boundary patterns.
references/nextjs-error-handling.md — App Router error.tsx, global-error.tsx, not-found.tsx.
references/async-and-reporting.md — useAsync hook and the reportError integration module.

Best Practices

Wrap at the route level for page-level isolation, and wrap third-party components separately.
Provide meaningful fallbacks with a recovery option.
Log every caught error to the monitoring service.
Do not catch errors the code cannot meaningfully handle.
Test error states in development.
