Common questions about rest vs graphql api comparison
REST for simple CRUD, public APIs, caching-heavy applications. GraphQL for complex data requirements, mobile apps needing flexible queries, when clients need different data shapes. Visualize tradeoffs.
REST requires multiple endpoints for related data (over/under-fetching). GraphQL allows clients to request exactly what they need in one query. Show N+1 problem in both and solutions (DataLoader, includes).
REST leverages HTTP caching (ETags, Cache-Control). GraphQL needs application-level caching (normalized cache, persisted queries). Visualize how each handles cache invalidation.
REST uses URL versioning (/v1/, /v2/) or header versioning. GraphQL evolves schema with deprecation, adding fields without breaking changes. Show how clients handle API evolution.
Yes! Use REST for simple endpoints, GraphQL for complex queries. GraphQL can wrap REST APIs. Show hybrid architecture with both patterns serving different use cases.
