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
: Implement functions like NewAggregateName to handle complex initialization and ensure the domain starts in a valid state. Go's package system is well-suited for DDD
: Focuses on "what" the system does rather than "how" it's stored, which is vital for long-term project health. and repository interfaces.
: 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
: Use Ports & Adapters (Hexagonal Architecture) alongside DDD to ensure that external technologies (like MongoDB or Postgres) do not leak into the business logic. Strategic Benefits
: Decoupled systems allow for easier unit testing of business rules without requiring a live database.
