REST API design benefits from resource-oriented patterns, clear verbs, and consistent versioning. Apply these principles to define predictable resource boundaries and improve interface maintainability across development teams and products.

Prevent N+1 queries in GraphQL APIs by implementing DataLoader usage within your resolvers. This batching pattern ensures scalable data fetching and avoids redundant database calls during complex nested query execution.

Design a GraphQL schema using a schema-first approach by defining queries, mutations, and subscriptions before writing resolver logic. This method enforces consistency, clarifies data contracts, and improves overall API usability.

Handle pagination and error handling across REST and GraphQL APIs by enforcing standardized patterns for cursor-based pagination and consistent error payloads. This ensures predictable integration and a developer-friendly interface.

Yes, you can use these API design principles to establish team standards for reviewing existing API specs. Evaluate your current REST and GraphQL interfaces against the checklist to identify inconsistencies and enforce best practices.
