backend-patterns

Structure a scalable Node.js backend using repository and service layer patterns to separate data access from business logic. This modular approach improves maintainability and developer velocity when refactoring monolithic Express applications.

Prevent N+1 query problems in database optimization by eager loading related data and using transactions. This Skill provides patterns to identify and resolve inefficient queries for scalable backend architectures.

Implement centralized error handling and caching in Node.js by establishing structured logging and Redis integration. These patterns ensure robust asynchronous task management and effective server-side application resilience.

Yes, you can apply these backend patterns with Next.js API routes and Supabase. The guidance covers authentication, rate limiting, and API design specifically tailored for these platforms to secure and optimize your endpoints.

JWT authentication and RBAC secure APIs by validating stateless tokens and enforcing role-based access control. This Skill demonstrates implementing these mechanisms to protect RESTful services against unauthorized requests.

You need background jobs and rate limiting in backend architecture when managing asynchronous tasks and protecting endpoints from excessive traffic. Implementing these patterns ensures scalable server-side application development under high load.
