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

  1. Use TypeScript: Type safety prevents runtime errors
  2. Implement proper error handling: Use custom error classes
  3. Validate input: Use libraries like Zod or Joi
  4. Use environment variables: Never hardcode secrets
  5. Implement logging: Use structured logging (Pino, Winston)
  6. Add rate limiting: Prevent abuse
  7. Use HTTPS: Always in production
  8. Implement CORS properly: Don't use * in production
  9. Use dependency injection: Easier testing and maintenance
  10. Write tests: Unit, integration, and E2E tests
  11. Handle graceful shutdown: Clean up resources
  12. Use connection pooling: For databases
  13. Implement health checks: For monitoring
  14. Use compression: Reduce response size
  15. Monitor performance: Use APM tools

Testing Patterns
