Architecture

DDD

Each directory contains:

• domain: Domain Service, Domain Rule, Entity, Value Object, Repository Interface
  • Layered architecture: Domain
  • Hexagonal architecture: Domain Model
  • Onion architecture: Domain Model, Domain Service
  • Clean architecture: Entities
• application: Application, Handler of Entity/Value Object, Dataflow
  • Layered architecture: Application
  • Hexagonal architecture: Application
  • Onion architecture: Application Service
  • Clean architecture: Use Cases, Controllers
• infra: Repository
  • Layered architecture: Infrastructure
  • Hexagonal architecture: Adapter
  • Onion architecture: Infrastructure
  • Clean architecture: Gateways
• presentation: Endpoint
  • Layered architecture: User Interface, Presentation
  • Hexagonal architecture: Adapter
  • Onion architecture: User Interface
  • Clean architecture: Presentaters
• usecase: Use Case, Requirements
  • The context in Agile software development, not DDD.

Event-driven architecture

NOT the Event Sourcing System.
