go-clean-architecture

Structure a Go clean architecture project by separating code into Domain, Application, and Infrastructure layers. This separation of concerns ensures dependencies point inward toward the domain, making the codebase scalable and maintainable.

The domain layer in Go clean architecture contains core business logic and entities. It sits at the center of the architecture, ensuring that business rules are independent of infrastructure and application layers.

Manage dependency injection in Golang clean architecture by ensuring dependencies point inward toward the domain layer. The infrastructure and application layers depend on the domain, never the other way around, preserving separation of concerns.

Common anti-patterns in Go architecture include outward dependency flow and mixing infrastructure concerns with domain logic. Avoiding these pitfalls ensures your application maintains a strict separation of concerns and remains testable.

Refactor a monolithic Go application into clean architecture when maintainability and testability decline. Implementing layered architecture and patterns like Repository and Service helps structure the codebase for better scalability.

Testing strategies for Go clean architecture focus on verifying layers independently. Because dependencies point inward, you can easily mock infrastructure and application layers to test domain logic in isolation.
