How I Used GitHub Copilot

I used GitHub Copilot to:

• Generate CRUD controller logic
• Debug API route handling
• Implement logging middleware
• Improve validation logic

All suggestions were reviewed and refined before use.

Testing the API

Use curl:

curl http://localhost:5134/api/users

Project Outcome

This API successfully demonstrates CRUD operations, validation, and middleware integration, fulfilling the assignment requirements.
