backend-patterns

To structure a scalable RESTful API in Node.js, establish consistent resource-oriented routes, apply versioning, and separate data access from business logic using repository and service layers. This separation improves testability and maintainability across Express backend projects.

Implement JWT authentication and RBAC by integrating them into your request processing pipelines as middleware. This pattern secures endpoints by validating tokens and enforcing role-based access control before reaching the service layer in your Node.js application.

Handle caching and rate limiting by applying specific patterns within your middleware pipeline. Implement caching strategies to improve performance and apply rate limiting to control request traffic, ensuring robust production systems for your Express API.

Yes, these backend patterns apply to Node.js, Express, and Next.js API projects. They provide structured guidance for RESTful routes, repositories, services, caching, auth, and observability that integrate directly into Next.js server-side API implementations.

Reliability patterns for background jobs and error handling include implementing retries for transient failures and structured logging for observability. These patterns ensure robust production systems by managing errors and asynchronous tasks effectively in your backend.
