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
: Ensuring that the code reflects the same terminology used by business experts (e.g., using LoanApplication instead of GenericForm ). Go's package system is well-suited for DDD
: 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). and repository interfaces.
: Define interfaces in the domain layer and provide implementations in the infrastructure layer to keep the system flexible and maintainable . Go's package system is well-suited for DDD
Any good sample example on domain driven design in go : r/golang
: Implement functions like NewAggregateName to handle complex initialization and ensure the domain starts in a valid state.
