backend-patterns

Structure Node.js APIs using repository, service, and controller layering patterns to enforce clear separation of concerns. This isolates data access, business logic, and routing, making backend applications scalable and maintainable across microservices and monoliths.

Implement caching and rate limiting in Express by applying middleware patterns for request throttling and response storage. These patterns support scalable API design across typical web services, microservices, and serverless functions.

Yes, you can apply these backend architecture patterns directly to Next.js API routes. The guidance covers pattern implementation for serverless functions, including data access layers, caching strategies, and scalable error handling.

Handle errors in a microservice architecture by applying scalable error handling patterns. This approach enforces reusable patterns and clear separation of concerns to manage failures consistently across distributed backend services and API endpoints.

Use the repository pattern for data access when you need to isolate database operations from business logic. It provides a clear abstraction layer over data sources, supporting REST, GraphQL, and various service architectures.
