build-service-and-repository-layers

You can separate business logic from data persistence by generating distinct service and repository layers. The service layer encapsulates business rules while the repository layer abstracts data access, decoupling operations for a maintainable codebase.

The repository pattern abstracts data persistence concerns by providing a clean interface for data access operations. You should use it when developing scalable and testable applications that require clear architectural separation and modular design.

You generate the basic structure for a new backend service and its corresponding repository by applying code generation to the architectural layers. This creates defined interfaces where the service orchestrates operations and interacts with the repository layer.

Decoupling business logic with service and repository layers works effectively for e-commerce platforms. For example, an OrderService handles business rules for order placement while an OrderRepository manages database interactions for saving and retrieving order data.

Yes, you need defined interfaces to build testable backend applications with modular design. Defined interfaces establish clear architectural separation between layers, satisfying the need for maintainable codebases through decoupled business logic and data persistence mechanisms.
