What are the best practices for designing a service layer?

When designing a service layer, consider separation of concerns, scalability, and reusability. It's crucial to keep your business logic separate from your data access logic.

Can you explain separation of concerns?

Separation of concerns means dividing a program into distinct sections, each addressing a separate concern. In a service layer, this helps maintain clean architecture and makes the code easier to manage.

What about error handling in the service layer?

Error handling is vital. Implement centralized error handling to catch exceptions and provide meaningful error messages to the client, ensuring a smooth user experience.

How can I ensure scalability in my service layer?

To ensure scalability, design your service layer to be stateless, use load balancing, and consider microservices architecture to handle increased loads effectively.
