NestJS 11 Clean Architecture

What problem does it solve?

Projects built with NestJS often suffer from architectural drift as they grow, making maintenance and testing harder. This Skill provides a practical NestJS 11 Clean Architecture pattern that enforces dependency injection, clear domain boundaries, and a predictable module layout to improve scalability and reliability.

Core Features & Use Cases

• Layered structure: Controller → Service → Repository → Database with inward dependencies.
• DI tokens and clean interfaces: avoid direct instantiations and promote testability.
• Domain logic in services and shared types to enable reuse across modules and potential CQRS adoption.
• Use Case: organize a new backend feature by creating a module, controller, service, and repository following the conventions described.

Quick Start

Create a new NestJS 11 project and organize modules, controllers, services, and repositories following the conventions outlined above.
