Show HN: Go-DDD: Production-ready DDD patterns and clean architecture in Go

2 points

Hey HN! I've been working on a comprehensive example of Domain-Driven Design implementation in Go that demonstrates clean architecture principles in practice.

The repo includes:

Hexagonal architecture with clear separation of concerns - CQRS (Command Query Responsibility Segregation) patterns for scalability & reliability - Event sourcing examples - Operating only on validated domain entities - Dependency injection setup - Handling Idempotency - Repository patterns with multiple storage backends - Testing strategies

What makes this different from other DDD examples is the focus on practical, production-ready patterns rather than just theoretical concepts. I've tried to show how these patterns actually work together in a real application structure. The codebase is designed to be educational – each layer is clearly separated and documented so you can see how data flows through the application and where business logic lives versus infrastructure concerns.

Would love feedback from the Go community on the patterns used and whether this helps clarify DDD concepts for others who've struggled with implementing clean architecture in Go projects.
