Global Error Handling

Try-catch blocks wrap code that might fail, capturing exceptions before they crash your app. Place them around API calls, database queries, and external service requests to catch errors, log them securely, and execute fallback logic or user-friendly messages instead of exposing technical details.

Generate user-friendly error messages that describe what went wrong in simple terms, while logging full technical details server-side. Avoid exposing stack traces, database schema, or API internals to the frontend; instead communicate the impact and next steps users should take.

Implement retry logic that attempts failed API calls multiple times with increasing delays between attempts. Use exponential backoff to avoid overwhelming a failing service, set a maximum retry count, and fall back to graceful degradation or cached data if all retries exhaust.

Error boundaries are React components that catch errors in child components, preventing full app crashes. They let you display fallback UI, log errors, and preserve app state in non-critical parts while isolating failures to specific sections of your interface.

Centralized error handling enforces consistent validation, logging, and user messaging across your entire API. It catches errors before they propagate, prevents sensitive data leaks, standardizes exception types, and makes debugging easier by creating a single source of truth for error responses.
