backend-patterns

Structure a scalable Node.js backend API using a layered repository-service-controller architecture. This pattern separates data access, business logic, and routing to enforce modular components, reducing architecture drift and supporting maintainable production systems.

Organize Express middleware and error handling by enforcing modular structures and secure data access patterns. Implement dedicated middleware and logging patterns to standardize asynchronous processing and consistently manage application errors across your API.

You need the repository-service-controller pattern when refactoring a Node.js or Next.js API for rapid iteration and scalability. It decouples database operations from business logic, enabling modular components and secure data access for growing production systems.

Yes, these backend patterns support both REST and GraphQL API design. The pattern catalog provides architectural guidance for Node.js, Express, and Next.js APIs, ensuring modular structures, caching, and database optimization apply across both paradigms.

Implement database optimization and caching in Node.js by applying the cataloged backend patterns. These patterns guide asynchronous processing, middleware integration, and secure data access to support scalable production environments.

Your Node.js backend architecture suffers from drift and rework due to unstructured codebases. Applying layered architecture patterns like repository-service-controller enforces modular structures, standardizes middleware, and reduces the architecture drift that causes rework.
