DDD is divided into strategic and tactical patterns. Tactical patterns are the primary focus when structuring a Go codebase.

: Focuses on "what" the system does rather than "how" it's stored, which is vital for long-term project health.

: Define interfaces in the domain layer and provide implementations in the infrastructure layer to keep the system flexible and maintainable . DDD is divided into strategic and tactical patterns

: Start by creating types that represent your business rules. Use Go structs to enforce constraints (e.g., a title must be between 1–50 characters).

Any good sample example on domain driven design in go : r/golang : Define interfaces in the domain layer and

: Clusters of domain objects treated as a single unit for data changes. For instance, a Customer aggregate might encapsulate validation and ID generation within a factory function like NewCustomer . Entities & Value Objects :

Go's package system is well-suited for DDD. A common approach is to use the internal directory to prevent external exposure of domain-specific logic. Responsibility Typical Go Package Core business logic, entities, and repository interfaces. internal/domain Application Orchestrates tasks and delegates to domain objects. internal/application Infrastructure Implements repository interfaces (DB, APIs). internal/infrastructure Interfaces Entry points for the system (HTTP, CLI, gRPC). internal/interfaces Key Tactical Implementation Steps Any good sample example on domain driven design

: Implement functions like NewAggregateName to handle complex initialization and ensure the domain starts in a valid state.
