backend-patterns

Structure a scalable Node.js API by applying repository, service, and middleware patterns to separate data access, business logic, and routing. This modular architecture improves testability and reduces boilerplate across REST and GraphQL services.

The best backend patterns for error handling in Express use centralized middleware to catch and process operational errors. Applying standardized error-handling patterns improves reliability and keeps your API maintainable as the codebase grows.

Yes, this approach works for migrating a monolithic Node.js application by applying repository and service patterns to decouple dependencies. It guides teams in restructuring routes and data access layers for a modular, testable API.

Add caching and observability to a Next.js backend by implementing dedicated logging and monitoring patterns. These operational patterns support robust production deployments by guiding structured data caching and application metrics.

Yes, you can use these backend design patterns for both REST and GraphQL services. The catalog provides API design patterns that structure routes, services, and data access layers effectively across multiple API paradigms.

You should evaluate avoiding the repository pattern when your Node.js application is a small, simple prototype with minimal data access logic. For such cases, direct database queries may reduce unnecessary boilerplate compared to a fully layered architecture.
