Implement DDD tactical patterns in Go by using composition, interfaces, unexported fields, and functional options to build domain models with rich business logic. This covers Entities, Value Objects, Aggregates, Repositories, and Domain Events using Go-native idioms.

Structure a Go aggregate by defining unexported fields for state and exposing behavior through methods. Define repository interfaces within the domain layer to handle persistence, ensuring the domain model remains decoupled from infrastructure.

Apply domain-driven design in Go by favoring composition over inheritance and using interfaces for polymorphism. Define domain models using unexported fields and functional options to enforce invariants, avoiding traditional OOP class hierarchies.

Use the Specification pattern in a Go domain model to encapsulate complex business rules and validation logic. It allows you to combine, reuse, and test specific business conditions without cluttering your aggregate or entity methods.

Yes, implement domain events using Go-native idioms by defining event interfaces and dispatching them within your aggregates. This maintains a clear layered architecture while keeping the domain logic decoupled from event handlers.

Yes, this guide can generate a complete Go implementation for an Order aggregate. It includes creating the necessary value objects, repository interfaces, and factory methods following idiomatic Domain-Driven Design principles.
