description: Create repository adapter with MongoDB schema following the ports & adapters pattern. Use when adding persistence for domain entities.
argument-hint: [module-name] [entity-name]
disable-model-invocation: true

Create repository infrastructure for "$1" entity in the $0 module.

Create these files in src/modules/$0/adapters/repository/:

  1. •$1.schema.ts - Mongoose schema definition
  2. •$1.adapter.ts - Repository adapter implementing IRepository
  3. •$1.service.ts - Service implementing the port interface
  4. •$1.module.ts - Adapter module for DI

Also create the port interface: 5. src/modules/$0/application/ports/$1.port.ts

Requirements:

  • •Schema: Use Mongoose decorators (@Schema, @Prop) from @nestjs/mongoose
  • •Adapter: Implement generic IRepository<T> interface
  • •Service: Implement the port interface defined in application layer
  • •Follow Repository pattern from shared/adapters/repository/
  • •Map between domain entities and database models
  • •Handle persistence concerns (MongoDB)
  • •Return domain entities, not database models
  • •Use proper error handling with Result pattern

Layer responsibilities:

  • •Port (application): Interface definition
  • •Adapter (adapters): Repository implementation
  • •Schema (adapters): Database mapping
  • •Module (adapters): DI configuration for adapters only
