How do I handle errors consistently with gqlgen in Go?

When working with gqlgen in Go, consistent error handling is crucial for maintaining a robust and understandable API. Here is how you can handle errors effectively:

1. Define Custom Error Types: Create specific types for different error scenarios to provide clarity in your API responses.
2. Use Middleware: Implement middleware to catch and format errors before they reach the client.
3. Return User-Friendly Messages: Avoid exposing internal errors; instead, provide user-friendly messages while logging the details for debugging.
4. Implement a Global Error Handler: Set up a centralized error handler in your schema resolver to manage errors in a uniform way.

By following these steps, errors can be handled systematically, improving the overall developer and user experience.
