What problem does it solve?

It solves the problem of building unreliable, hard-to-maintain Node.js backends by providing practical, production-grade patterns for server setup, middleware, error handling, security, and data access.

Core Features & Use Cases

• Production server scaffolding: Express or Fastify setups with security, compression, CORS, request parsing, and logging.
• Robust API architecture: Layered architecture with controllers, services, repositories, and shared utilities.
• Security and reliability patterns: JWT authentication/authorization, input validation, rate limiting, consistent error handling, and health-oriented operational guidance.
• Data and performance strategies: SQL (pg) connection pooling, MongoDB (Mongoose) integration patterns, transactions, and Redis-backed caching.
• Real-world use cases: REST APIs, GraphQL backends, microservices, authentication-enabled services, background jobs, and WebSocket-enabled real-time systems.

Quick Start

Use this skill when designing a new Node.js REST or GraphQL backend and ask an AI to generate a layered Express/Fastify code skeleton with JWT auth, request validation (Zod), centralized error handling, rate limiting, and a pg-backed repository layer.
