backend-patterns

To structure backend architecture in Node.js, implement the Repository, Service Layer, and Middleware patterns to separate data access, business logic, and request handling. This separation ensures your server-side applications remain scalable and maintainable.

The best way to prevent N+1 query problems in database optimization is by applying proper query techniques and indexing strategies. This Skill provides guidance on refactoring data access using the repository pattern to execute efficient batched queries.

Redis caching improves backend API performance by storing frequently accessed data in memory, reducing database load. This Skill explains how to implement various caching mechanisms alongside CDN strategies to significantly decrease server response times.

Yes, you can use these backend patterns with Next.js API routes. The Skill provides specific server-side best practices for Node.js, Express, and Next.js environments, covering service layer implementation and transaction management.

To implement JWT validation and Role-Based Access Control (RBAC) for API security, apply robust error handling and authorization middleware. This Skill covers security measures including rate limiting to protect your endpoints from unauthorized access.

You should use transaction management in database operations when executing multiple related queries that must succeed or fail together. This prevents data inconsistency and is a core server-side best practice covered in this Skill's database optimization guidance.
