Repository pattern in Go service

This article explains the repository pattern in Go services, focusing on achieving clean separation of concerns, testability, and flexibility. It covers how to define persistence abstractions (interfaces) in the domain model and implement them as adapters, allowing easy swapping of storage layers (e.g., SQLite to Postgres) without changing business logic. The article emphasizes practical benefits like encapsulation, scalability, and isolated testing, with a domain-first project structure aligned with Go's package philosophy. Suitable for developers building gRPC, HTTP, or WebSocket services.
