nodejs-backend-patterns

Quick Review

Excellent comprehensive skill for Node.js backend development. The description accurately reflects the extensive capabilities covered including Express/Fastify setup, layered architecture, middleware patterns, error handling, authentication, database integration, caching, and production best practices. The skill provides substantial task knowledge with complete, production-ready code examples for controllers, services, repositories, DI containers, JWT auth, transactions, and caching strategies. Structure is clear with logical sections, though at ~500 lines it borders on lengthy for a single file - minor modularization could improve navigation. Novelty is solid: while individual patterns are standard, the comprehensive integration of TypeScript, dependency injection, proper error handling, transaction patterns, and caching with concrete implementations provides significant value over what a CLI agent could assemble efficiently. This meaningfully reduces token cost for building production-grade Node.js backends.
