When developing APIs, error handling is critical for maintaining reliability and user experience. Here’s a guide to help you implement effective error handling strategies.

🚨 Common Error Types

  • 4xx Client Errors (e.g., 400, 404, 405)
  • 5xx Server Errors (e.g., 500, 502, 504)
  • Custom Errors for business logic validation

💡 Handling Strategies

  1. Use structured error responses with status_code, message, and details.
  2. Implement logging to track errors during production.
  3. Add rate limiting to prevent abuse.

📚 Best Practices

  • Always return JSON for error responses.
  • Use HTTP headers like Content-Type and Cache-Control.
  • Test with mock errors to ensure robustness.
