# Hexagonal Architecture - Packmind Monorepo ## Architecture Map Every domain package follows a three-layer hexagonal (ports & adapters) architecture. Dependencies flow **inward only**: Infrastructure -> Application -> Domain. ``` packages/{domain}/src/ ├── domain/ # Pure business logic, zero dependencies │ ├── entities/ # Domain entities and value objects │ ├── repositories/ # Repository interfaces (ports) │ ├── jobs/ # Delayed job definitions │ ├── errors/ # Domain-specific error classes │ ├── utils/ # Domain-specific utility functions │ └── types/ # Domain-specific type definitions │ ├── application/ # Orchestration & coordination │ ├── useCases/{name}/ # One folder per use case │ │ └── {name}.usecase.ts │ ├── services/ # Domain services + service aggregator │ ├── adapter/ # Outbound adapter (implements port) │ ├── listeners/ # Domain event listeners │ └── jobs/ # Delayed job implementations │ ├── infra/ # Concrete implementations │ ├── repositories/ # Repository implementations (TypeORM) │ ├── schemas/ # TypeORM EntitySchema definitions │ └── jobs/ # Job factories │ └── index.ts ...
