ddd-primitives

What problem does it solve?

This Skill aids in implementing advanced Domain-Driven Design patterns and practices, addressing invariants, value objects, specifications, aggregate roots, domain events, and state machines, ensuring robust and maintainable domain logic.

Core Features & Use Cases

• Value Object Modeling: Offers a template for value objects with structural equality, ideal for concepts with real invariants.
• Specification Implementation: Provides a mechanism for composable business rules that run both in-memory and in SQL.
• Strongly Typed Ids: Helps eliminate primitive obsession in id management.
• Aggregate Root and Domain Events: Facilitates the creation of entities that own invariants and can react to changes.
• StateMachine: Enables guarded state transitions without exceptions, suitable for entities with complex status fields.
• Use Case: Use this Skill when building a complex system that requires strict enforcement of business rules and domain logic.

Quick Start

Apply the 'ddd-primitives' skill to an entity that requires value objects, specifications, and state management.
