About
This skill provides comprehensive guidance for architecting scalable and maintainable Node.js server-side applications. It implements battle-tested patterns such as layered architecture (Controller-Service-Repository), dependency injection, and robust middleware for authentication and validation. Whether building REST APIs, GraphQL backends, or microservices, this skill ensures best practices in security, error handling, and performance are baked into the development process from the start, allowing developers to focus on core business logic.
