Node.js Backend Patterns

About

Provides comprehensive architectural guidance and implementation patterns for building scalable, maintainable Node.js server applications. It covers essential backend components including core framework setup, layered architecture (Controller/Service/Repository), and dependency injection. The skill also facilitates the integration of robust middleware for security, Zod-based validation, and rate limiting, alongside a standardized global error-handling strategy to ensure production-grade reliability and performance.
