REST API design for Node.js involves structuring endpoints, request/response handling, and routing patterns. Backend patterns provide modular approaches to separate concerns, handle authentication, implement middleware, and manage error responses consistently across your Express or Next.js application.

N+1 query avoidance is a database optimization pattern where you load related data efficiently instead of querying in loops. Backend patterns cover query strategies, batching, eager loading, and caching techniques to reduce database calls and improve API response times.

Caching stores frequently accessed data to reduce database load and latency. Backend patterns provide concrete examples for adding caching middleware, managing cache invalidation, and selecting appropriate caching strategies for different API endpoints and data types.

Backend patterns cover multiple API design approaches including REST, GraphQL, and routing strategies. The core patterns for authentication, error handling, database optimization, and middleware apply across API styles, giving you flexible guidance for your chosen architecture.

Authentication and middleware patterns establish secure, consistent request handling in production systems. Backend patterns provide decision guidance for selecting appropriate patterns, implementing token-based auth, rate limiting, and composing middleware stacks for Node.js/Express/Next.js workloads.

No. Backend patterns provide guidance for multiple API design approaches—REST, GraphQL, and routing—so you can apply the patterns relevant to your chosen architecture. Each pattern includes concrete examples and decision guidance for your specific tech stack.
