To structure a Go project and separate business logic from infrastructure, use a standardized directory layout with clear package responsibilities. Place domain models in pkg/model, implement business logic in pkg/logic behind interfaces, and isolate external integrations in pkg/driver.

The best way to organize a Go microservice codebase for testability is applying clean architecture conventions. Define specific directory roles for cmd, pkg, and config to ensure modularity, support dependency inversion, and make refactoring easier.

To refactor an existing Go codebase to clean architecture, move domain models into pkg/model, relocate business logic to pkg/logic behind interfaces, and shift external integrations to pkg/driver. This separation prevents tangled code and reduces onboarding friction.

You need a standardized Go project layout when creating new services, refactoring existing codebases, or preparing projects for testing and deployment. It prevents mixed business logic and infrastructure, ensuring predictable build artifacts and maintainable code.

Yes, the Go project structure convention supports dependency inversion by defining specific package responsibilities and file placement. Implementing business logic in pkg/logic behind interfaces and placing external integrations in pkg/driver ensures modularity and testability.
