nodejs-backend-patterns

Build a production-ready Node.js backend by using Express or Fastify with TypeScript, implementing layered architecture, dependency injection, JWT authentication, database integration, structured logging, and robust error handling for reliable API services.

Structure authentication and database integration in a Node.js API by applying layered architecture with dependency injection, implementing JWT authentication, and connecting to PostgreSQL or MongoDB with connection pooling, transactions, and graceful shutdown patterns.

Yes, this Node.js backend approach supports both REST APIs and GraphQL servers. It guides Express and Fastify implementations for REST, GraphQL, and microservices, ensuring consistent API responses, validation, and robust error handling across different service types.

Yes, you can use Fastify instead of Express for microservices in Node.js. The implementation guides both Express and Fastify frameworks for microservices, providing production patterns like rate limiting, caching, and graceful shutdown for either framework.

Your Node.js backend needs graceful shutdown and rate limiting to ensure reliable service operation at scale. Graceful shutdown prevents database connection drops during transactions, while rate limiting protects API endpoints from excessive traffic and abuse.
