golang-hexagonal-architecture

Structure a Go project using hexagonal architecture by organizing packages into core domains, application logic, adapters, and infrastructure, ensuring dependencies flow inward. This promotes clear module responsibility and testable boundaries for maintainable codebases.

Enforce dependency inversion in Golang by applying strict package dependency rules and explicit wiring in the composition root. This pattern ensures core domain logic remains isolated from infrastructure, improving overall project clarity and scalability.

You need hexagonal architecture for medium to large Go service projects requiring maintainable, testable boundaries. It is particularly useful when refactoring a monolith into well-structured modules with clear bounded contexts and separated layers.

Organize Go packages for modular design by defining strict boundaries for core domains, application logic, and adapters. This structural pattern guides dependency management and port design, transforming a monolith into a scalable, well-structured project.

Yes, hexagonal architecture in Go requires explicit wiring in the composition root to improve clarity and scalability. This design pattern enforces strict package dependency rules, ensuring dependencies flow inward toward the core domain.

The limitation of hexagonal architecture in Golang is the overhead of defining strict package dependency rules and explicit port design. It applies best to medium to large projects; simple applications may not require this level of modular layer separation.
