backend-patterns

Scalable Node.js backends use repository, service, and controller layers to separate data access, business logic, and routing. Organize Express or Next.js APIs into these clear layers to enforce pattern integration for REST and GraphQL endpoints while improving maintainability.

Middleware patterns for authentication and rate limiting in Node.js APIs enforce standard request handling and protect endpoints. Integrate structured middleware setups in Express to manage access control and throttle requests, which ensures maintainability and observability.

Error handling and structured logging patterns in Express capture exceptions and standardize log output for observability. Apply specific middleware patterns to centralize error responses and format logs, which simplifies debugging and maintains consistent API behavior.

Yes, these backend patterns apply to serverless contexts and Next.js API routes. The patterns support REST and GraphQL endpoint structuring across Express and serverless environments, automating data access layer setup and standardizing middleware usage for scalable APIs.

Implement caching in a Node.js data access layer by applying repository layering patterns that standardize data retrieval. Enforcing these caching patterns within the repository structure reduces database load and improves API response times across REST and GraphQL endpoints.
