nextjs-error-handling

Next.js API errors and server action errors are handled using safe-action wrappers and structured error classes to gracefully catch validation and operational faults, returning consistent messaging. This pattern ensures resilience across your routes and server-side logic.

Centralized error handling in a Next.js app is structured by defining reusable error classes like AppError and ValidationError alongside global and route-level error boundaries. This approach delivers consistent user-facing messages and recovery flows.

Next.js error boundaries work for route-level errors by using dedicated error components to catch segment faults, present friendly fallbacks, and offer retry options. This isolates failures to specific route segments without crashing the entire application.

Yes, this error handling approach supports not found pages and recovery patterns by providing structured flows for NotFoundError classes and not-found handling. It enables graceful presentation of missing resources and structured recovery across pages.

Yes, you can use TypeScript to define custom error classes for Next.js server actions, including AppError, UnauthorizedError, and ForbiddenError. These classes enforce consistent messaging and status codes across your server-side operations.

You need safe-action wrappers for Next.js server actions to gracefully catch and format validation and operational errors before they reach the client. Wrappers ensure operational faults return predictable, structured responses instead of unhandled exceptions.
