backend-patterns

Implement scalable backend patterns using modular repository, service, and controller layers to decouple data access from business logic. This structure maintains consistency across Node.js, Express, and Next.js API routes while preventing ad-hoc designs in growing applications.

The best way to design REST and GraphQL endpoints is applying standardized patterns for routing, data access, and validation. Using consistent service layers ensures both API paradigms handle requests uniformly across your server-side architecture.

Implement middleware and error handling for Next.js API routes by applying structured patterns that capture exceptions and validate requests. This approach enforces consistent error responses and processing logic across all endpoint handlers.

Yes, these backend patterns directly support building e-commerce, analytics, or internal tooling APIs. The guide provides specific scenarios and templates for structuring modules, services, and data access layers to handle scalable API requirements.

No specific database or ORM is required. The patterns focus on designing abstract data access layers and caching strategies, allowing you to integrate your preferred database technology within the Node.js server-side architecture.
