backend-patterns

The repository-service-controller pattern separates API logic into layers: repositories handle database access, services contain business logic, and controllers manage HTTP request handling. This layering improves testability and maintainability in Node.js services.

Structure scalable Node.js APIs by applying repository-service-controller layering, database optimization, and caching patterns. Use middleware for robust error handling and monitoring guidelines to improve reliability under high traffic.

Yes, these backend architecture patterns apply across both RESTful and GraphQL APIs. They provide clean routing, resource management, and separation of concerns for enterprise Node.js projects regardless of the API protocol chosen.

The best way to handle database queries in a layered backend is using the repository pattern. It isolates database access within repository layers, allowing services to manage business logic efficiently while optimizing queries for performance.

Yes, implementing retries and monitoring is necessary for robust backend operations. These guidelines, alongside caching and error-handling patterns, improve reliability and ensure your scalable API maintains performance during failures.
