backend-patterns

Structure your Node.js API by separating data access into repository layers and business logic into service layers. This pattern isolates database operations, making your Express or Next.js services maintainable and independently testable.

Prevent N+1 queries in Node.js by applying indexing and optimized data fetching patterns within your repository layer. These database optimization strategies reduce redundant queries and significantly improve API response times.

Implement centralized error handling and rate limiting in Express by configuring middleware layers. This approach standardizes HTTP responses, applies authentication checks, and protects backend services from excessive request volumes.

Yes, these backend architecture patterns support both Next.js and GraphQL implementations. They provide structured schemas and repository layering to maintain consistent data access across RESTful and GraphQL API designs.

Structured logging formats application logs into consistent, searchable records for production observability. Integrating monitoring hooks with your Node.js services allows you to track reliability metrics and diagnose API failures efficiently.
