From the author

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.

AutoGineer summary

Written by AutoGineer from the skill’s own files, not by the author

This skill provides a structured approach to developing scalable and maintainable Node.js backend applications. It covers essential architectural patterns, such as layered architecture and dependency injection, alongside practical implementations for Express.js and Fastify. The guidance emphasizes production readiness through robust error handling, input validation, secure configuration, and efficient database integration for both SQL and NoSQL environments.

What it does

  • Defines layered architecture for clean separation of concerns
  • Provides setup patterns for Express.js and Fastify frameworks
  • Demonstrates dependency injection for improved testability
  • Outlines database integration patterns for PostgreSQL and MongoDB
  • Establishes best practices for security, logging, and performance
  • Offers guidance on request validation and structured error handling

When to use it

  • When architecting a new Node.js REST or GraphQL API
  • When refactoring existing services for better maintainability
  • When implementing authentication and authorization flows
  • When setting up database connection pooling and transaction management
  • When standardizing middleware and error handling across microservices

Advantages

  • Promotes type safety and maintainable code structures
  • Encourages modular design through dependency injection
  • Reduces boilerplate with proven architectural patterns
  • Improves application security and production reliability
  • Facilitates easier testing and resource management

Usage examples

“How should I structure my Node.js project to separate business logic from HTTP controllers?”
The agent will provide a layered architecture template, showing how to organize code into controllers, services, and repositories.
“Show me how to implement dependency injection in a Node.js service.”
The agent will provide a code example of a DI container that manages service and repository instances, improving testability.
“What is the best way to handle database connections in a production Node.js app?”
The agent will explain connection pooling for PostgreSQL or Mongoose connection management, including graceful shutdown procedures.
“How do I set up a basic Fastify server with schema validation?”
The agent will provide a Fastify boilerplate including plugin registration and route-level schema validation.

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

See javascript-testing-patterns skill for comprehensive testing guidance.
