nodejs-backend-patterns

Structure a production-ready Node.js backend using layered architecture, dependency injection, and robust error handling patterns to ensure scalability and maintainability across Express and Fastify frameworks.

Implement authentication and rate limiting in Express by applying middleware integration patterns that separate concerns, allowing secure and efficient request processing before hitting route handlers.

Yes, the Node.js backend patterns guide works with both PostgreSQL and MongoDB, providing specific database integration solutions including transaction handling and data persistence strategies.

Yes, you can use the same architectural patterns for Fastify and Express. The guide demonstrates framework-agnostic patterns for middleware, validation, and logging applicable to both.

Handle errors and validation in a scalable Node.js API by implementing centralized error handling strategies and middleware validation patterns to catch issues consistently across all endpoints.
