backend-patterns

Structure Node.js backend applications using repository and service layer patterns to separate data access from business logic. This approach ensures scalable and maintainable server-side code by isolating API route handlers from direct database queries.

Prevent N+1 query problems in database optimization by applying eager loading and proper query structuring. This Skill provides patterns to identify and resolve inefficient data fetching loops, ensuring transactional integrity and reducing redundant database calls.

The Redis cache-aside strategy works by checking the cache for data before querying the database, storing the result if missing. This pattern accelerates API route responses by reducing direct database load and optimizing repeated data retrieval operations.

Yes, you can implement role-based access control and JWT validation in Next.js API routes. This Skill covers authentication and authorization patterns to secure endpoints, ensuring only users with valid tokens and specific roles can access protected resources.

Use background jobs and rate limiting in backend architecture when handling asynchronous tasks and protecting APIs from excessive traffic. This Skill demonstrates setting up simple job queues for deferred processing and in-memory rate limiters to prevent API abuse.

Set up centralized error handling and structured logging in Express by implementing a global error handler that catches and processes exceptions uniformly. This approach pairs with structured logging to improve server-side monitoring and retry mechanisms.
