What problem does it solve?

Comprehensive pattern guidelines and boilerplate for implementing NestJS services at scale, including Model Services, Orchestration Services, and business logic with NestJS decorators, to promote consistency and maintainability across modules.

Core Features & Use Cases

• Standardized service layering using BaseModelService, Model/Orchestration separation, and repository-driven data access.
• Support for transactional orchestration with CLS-based @Transactional, and safe error handling patterns.
• Enforced validation via schema payloads and decoupling from ORM types within service methods.

Quick Start

Create a new NestJS service by extending BaseModelService, inject the repository, and follow the Model and Orchestration patterns described in this skill to implement consistent business logic.
