nodejs-backend-patterns
Build production-ready Node.js backend services with Express/Fastify, implementing middleware patterns, error handling, authentication, database integration, and API design best practices. Use when creating Node.js servers, REST APIs, GraphQL backends, or microservices architectures.
Why this skill is useful
Provides specific middleware patterns, error handling techniques, and architectural patterns for Node.js applications that the AI wouldn't reliably generate on its own.
What it needs
Requires node installed locally. About 9k tokens when loaded. Last updated 2026-08-07. 405 stars on the source repository.
