backend-patterns

Structure a scalable Node.js backend by separating data access from business logic using repository and service layer patterns, implementing RESTful resource-based endpoints, and standardizing centralized error handling in Express and Next.js API routes.

Handle API rate limiting and caching in Node.js by applying standardized backend architecture patterns that include middleware-based request processing pipelines, retry strategies, and basic caching mechanisms to improve reliability and performance.

The repository and service layer pattern in Express API design works by isolating data access operations in repositories while keeping business logic in services, ensuring RESTful routing remains decoupled from database interactions for maintainability.

Yes, you can apply these backend architecture patterns with Next.js API routes to standardize middleware pipelines, authentication scaffolding, structured logging, and centralized error handling across your server-side application.

Implement centralized error handling and observability in a Node.js backend through middleware pipelines that catch errors uniformly, combined with structured logging and error reporting patterns designed for long-term maintainability.

No external dependencies are required to set up authentication scaffolding and middleware pipelines, as the Skill provides dependency-free standard patterns for request processing, security, and observability across Node.js backends.
