Structure a Go project by separating domain, application, and data layers into internal modules, enforcing dependency direction toward the domain, and wiring dependencies with a DI provider to reduce coupling and improve testability.

The repository pattern in Go abstracts data layer access behind interfaces, keeping domain and application layers decoupled from sql mapping and data sources; use it when building scalable services needing testable boundaries and clear module separation.

Yes, Wire works with Clean Architecture by generating DI providers that wire dependencies across domain, application, and data layers, enforcing dependency direction and reducing manual wiring errors in scalable Go services.

Enforce dependency direction in Go by organizing internal modules with clear boundaries, defining repository interfaces in the domain layer, and ensuring application and data layers depend inward toward domain entities, preventing circular dependencies and reducing coupling.

The best way to organize Go layers is to isolate domain entities and repository interfaces in the domain layer, place use-case logic in the application layer, and restrict sql mapping and data access to the data layer, wiring them together with a DI provider.
