Go Clean Architecture Guide

About

This skill provides a comprehensive framework for implementing Clean and Hexagonal architecture in Go projects. It guides developers through maintaining strict dependency rules where layers point inward, managing interface ownership at the consumer level, and organizing code into standardized folder structures. It is particularly useful when bootstrapping new Go services, refactoring existing packages to improve testability, or ensuring consistent domain boundaries across a distributed system using domain-driven design principles.

Key Features

• Infrastructure-as-Code organization for CDK and Lambda entrypoints
• Clear separation between business logic, transport layers, and adapters
• Interface segregation and consumer-side interface ownership
• 0 GitHub stars
• Strict inward-pointing dependency rule enforcement
• Standardized Go project folder structure for internal and external packages

Use Cases

• Structuring AWS Lambda and CDK infrastructure alongside Go domain logic
• Refactoring legacy Go code to eliminate circular dependencies
• Bootstrapping a new Go microservice with hexagonal architecture
