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

Testing Patterns

Use this skill when asked to remove AI-isms, clean up AI writing, edit a draft for AI tells, audit a README, changelog, release note, PR description, or blog post for machine-sounding prose, or make text sound less like AI. Supports a detect-only mode, a rewrite mode, and an edit-in-place mode, with optional voice and context profiles.
  • Abacktesting-frameworksBuild robust backtesting systems for trading strategies with proper handling of look-ahead bias, survivorship bias, and transaction costs. Use when developing trading algorithms, validating strategies, or building backtesting infrastructure.
  • Abazel-build-optimizationOptimize Bazel builds for large-scale monorepos. Use when configuring Bazel, implementing remote execution, or optimizing build performance for enterprise codebases.
  • Abefore-you-buildPre-build product and feature risk review for founders, product managers, and AI-assisted builders. Use this skill when the user is about to build a landing page, MVP, SaaS product, internal tool, agent workflow, or major feature and needs to check demand, positioning, monetization, retention, trust, distribution, and adoption risk before implementation starts.
