nodejs-backend-patterns

A production-ready Node.js backend uses a layered architecture with controllers, services, and repositories to separate concerns. This Skill guides you in setting up Express.js or Fastify with dependency injection and middleware for maintainable API development.

The best way to handle errors in a Node.js microservice is implementing robust error handling middleware alongside consistent API response formatting. This Skill demonstrates patterns to catch, process, and format errors uniformly across your backend services.

You implement dependency injection in a TypeScript backend by decoupling your services and repositories, passing dependencies directly into classes or controllers. This Skill covers dependency injection patterns to build maintainable and testable backend services.

Yes, these Node.js backend patterns support both SQL and NoSQL database integration through the repository layer. This Skill guides you in connecting your Express or Fastify API to databases while keeping data access logic cleanly separated.

You add caching strategies to a Fastify or Express API by implementing middleware or service-level caching patterns to store frequent query results. This Skill provides examples for integrating caching into your Node.js backend to improve API response times.

You need layered architecture for Node.js microservices to ensure scalable and secure API development by isolating business logic from routing and data access. This Skill helps you scaffold controllers, services, and repositories for maintainable backend code.
