nodejs-backend-patterns

Build a scalable Node.js backend using layered design, dependency injection, and middleware. This provides architectural patterns for maintainable Express applications, cleanly separating routing, business logic, and database integration.

Implement authentication and input validation in a Node.js API by applying structured middleware and architectural patterns. This secures API endpoints by validating requests before they reach core business logic.

Yes, you can use Fastify instead of Express for production-ready Node.js microservices. Architectural guidance covers both frameworks for developing scalable REST APIs, GraphQL servers, and microservices.

Dependency injection improves Node.js backend architecture by decoupling components, making services easier to test and maintain. It is a core pattern for building layered designs supporting scalable backend applications.

Set up error handling and logging for Node.js REST APIs using centralized middleware. This ensures predictable request tracing and error management across services following industry best practices.
