REST API best practices involve establishing clear URL naming conventions and using predictable HTTP status codes for informative error responses. This ensures your endpoints remain consistent and maintainable across various scenarios like data creation or bad requests.

Designing a GraphQL schema to prevent N+1 issues requires a schema-first development approach. By defining clear types and contracts upfront, you structure data retrieval efficiently to avoid redundant database queries during nested resolvers.

Implementing API versioning and pagination involves defining strategies for API evolution and efficient data retrieval. Applying these principles when designing new endpoints ensures your backend services scale without requiring immediate refactoring.

The correct HTTP status code for a newly created resource is 201. Using precise HTTP status codes for API responses ensures predictable error handling and clear communication of operation results to API consumers.

Yes, these API design principles apply directly to creating robust backend services including Next.js API routes and Supabase Edge Functions. Defining solid contracts early prevents costly rewrites when building these endpoints.

You should establish project-wide API conventions before implementing new endpoints or writing API documentation. Defining contracts for resource naming, versioning, and authentication early prevents costly rewrites and ensures scalable backend services.
