nodejs-backend-patterns
🎯SkillGuidance for building reliable server-side apps with Node.js, using Express or Fastify. It covers login, error handling, databases, API design and a list of proven best practices.
Installation
npx skills add wshobson/agents --skill nodejs-backend-patternsRun it in a terminal; it asks which AI coding tools to install it for (Claude Code, Codex, Cursor and more).

After installing
Ask for related work and the agent uses it on its own, or call it yourself.

What this skill does
Overview
This skill helps your AI assistant build the server side of an app with Node.js, a way to run JavaScript on a server. It focuses on Express and Fastify, two popular tools for handling web requests. It gives a short list of best practices and points to a longer file of detailed patterns.
Key Features
- Build APIs, which are the endpoints other apps call to get or send data.
- Add user login and control what each user is allowed to do.
- Connect to SQL and NoSQL databases and reuse connections efficiently.
- Check incoming data, log events and limit how often clients can call you.
- Add health checks and shut the server down cleanly.
Who is this for?
This is for developers creating web servers, APIs or small connected services in Node.js. It helps when you want code that is ready for real users, not just a demo. Testing advice lives in a separate skill, javascript-testing-patterns.

View on GitHub →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.
Node.js Backend Patterns
Comprehensive guidance for building scalable, maintainable, and production-ready Node.js backend applications with modern frameworks, architectural patterns, and best practices.
When to Use This Skill
- Building REST APIs or GraphQL servers
- Creating microservices with Node.js
- Implementing authentication and authorization
- Designing scalable backend architectures
- Setting up middleware and error handling
- Integrating databases (SQL and NoSQL)
- Building real-time applications with WebSockets
- Implementing background job processing
Detailed patterns and worked examples
Detailed pattern documentation lives in references/details.md. Read that file when the navigation tier above is insufficient.
Best Practices
- Use TypeScript: Type safety prevents runtime errors
- Implement proper error handling: Use custom error classes
- Validate input: Use libraries like Zod or Joi
- Use environment variables: Never hardcode secrets
- Implement logging: Use structured logging (Pino, Winston)
- Add rate limiting: Prevent abuse
- Use HTTPS: Always in production
- Implement CORS properly: Don't use
*in production - Use dependency injection: Easier testing and maintenance
- Write tests: Unit, integration, and E2E tests
- Handle graceful shutdown: Clean up resources
- Use connection pooling: For databases
- Implement health checks: For monitoring
- Use compression: Reduce response size
- Monitor performance: Use APM tools
Testing Patterns
