nodejs-backend-patterns

Validate API requests in Node.js using Zod-based schema validation integrated within your Express or Fastify middleware. This approach ensures robust input checking before data reaches your business logic, preventing malformed requests and improving overall API reliability.

Handle Fastify API errors using a centralized error handling middleware that standardizes API responses. This pattern catches exceptions across your microservices, returning consistent error formats while ensuring sensitive details are never leaked to the client.

Yes, these Node.js backend patterns support both Express and Fastify frameworks. The implementation provides framework-appropriate server setup for REST API development, applying identical production concerns like rate limiting, compression, and CORS to whichever runtime you choose.

Implement authentication and rate limiting in a Node.js microservice by applying dedicated middleware patterns during server setup. These production-ready patterns intercept incoming requests to verify authorization tokens and restrict API traffic, ensuring secure and reliable backend services.

Use dependency injection concepts in Node.js backend architecture when building scalable microservices that require clear separation of concerns. This pattern decouples your services from repositories, making database integration, connection pooling, and transaction safety easier to manage and test.
