error-handling

Error handling for async operations involves wrapping fetch calls and promises in try/catch blocks to catch exceptions. This prevents application crashes and allows you to execute fallback logic, ensuring robust error management when network or server issues occur.

Implementing user-friendly error messages requires catching API failures in a try/catch block and updating the UI state with a clear, non-cryptic fallback message. Simultaneously, you should log the detailed technical error for developers to aid in debugging without exposing raw errors to end users.

A useAsyncCall hook manages exception handling by encapsulating asynchronous logic and automatically tracking loading, success, and error states. This pattern standardizes async error management across your application, ensuring consistent error boundaries and user feedback mechanisms.

Your application crashes because async functions lack proper exception handling via try/catch blocks. Without robust error management mechanisms to catch the rejection, the unhandled exception propagates and crashes the application rather than triggering a fallback UI state or user-facing error message.

Error boundaries in React primarily catch synchronous rendering errors, not asynchronous errors from API calls. You must combine error boundaries with try/catch blocks within your async functions to fully manage both UI rendering exceptions and async operation failures.
