go-clean-architecture

Structure a Go project using clean architecture by organizing code into distinct layers: Entities, Use Cases, Interfaces/Adapters, and Frameworks & Drivers. This multi-layer structure separates core domain rules from infrastructure concerns, enabling easier testing and evolution.

The dependency direction guideline for a Go clean architecture service mandates that dependencies point inward toward the domain. Infrastructure and frameworks depend on use cases and entities, ensuring core business logic remains isolated from external concerns and highly testable.

You need clean architecture for a Go backend service when the project suffers from tangled dependencies and brittle boundaries between business logic and infrastructure. It provides a repeatable template to ensure straightforward wiring to infrastructure and testable domain logic.

Yes, you can use clean architecture to separate domain logic from infrastructure in Go. This approach applies clear boundaries and naming conventions between layers, ensuring your core domain rules remain independent of external frameworks and databases.

The best way to scaffold a new Go service with testable layers is following a clean architecture template. This provides a multi-layer structure with reference implementation alignment, ensuring your use cases and entities are isolated for straightforward testing.
