🏆 빠른 결론

무승부! 둘 다 훌륭한 선택입니다.

GraphQL excels when clients need flexible data fetching and you have complex, interconnected data. REST is simpler, better cached, and ideal for straightforward CRUD APIs.

GraphQL란?

G

GraphQL

API Technologies

graphql.org

GraphQL is a query language for APIs developed by Facebook. It allows clients to request exactly the data they need, reducing over-fetching and under-fetching common with REST APIs.

장점

  • Clients request exactly the data they need
  • Single endpoint for all queries
  • Strong type system with schema
  • Real-time subscriptions built-in
  • Excellent developer tooling (GraphiQL, Apollo)
  • Self-documenting via introspection

단점

  • More complex to set up and maintain
  • Caching is harder than REST
  • N+1 query problem requires careful handling
  • Steeper learning curve
  • File uploads not natively supported
  • Rate limiting is more complex

REST API란?

R

REST API

API Technologies

restfulapi.net

REST (Representational State Transfer) is the most widely used architectural style for web APIs. It uses standard HTTP methods and is simple, stateless, and well-understood by developers.

장점

  • Simple and well-understood
  • Native HTTP caching support
  • Stateless architecture
  • Wide tooling and library support
  • Easy to debug with standard HTTP tools
  • Works naturally with CDNs

단점

  • Over-fetching and under-fetching data
  • Multiple endpoints to maintain
  • Versioning can be challenging
  • No standard type system
  • Documentation requires separate tools
  • No built-in real-time support

🏆우리의 추천

광범위한 분석과 테스트 후, 우리의 결론은 다음과 같습니다: GraphQL와 REST API 모두 생산성을 크게 향상시킬 수 있는 훌륭한 도구입니다. 최선의 선택은 여러분의 구체적인 요구 사항, 워크플로우, 우선순위에 따라 달라집니다.

GraphQL을 선택하세요:

You have complex data relationships, multiple client types (web, mobile) with different data needs, or need real-time subscriptions.

REST API을 선택하세요:

You're building simple CRUD APIs, need strong HTTP caching, or want maximum simplicity and the widest ecosystem support.

자주 묻는 질문

No. GraphQL is an alternative, not a replacement. Many companies use both: GraphQL for complex client-facing APIs and REST for simple internal services.

최종 결론: 무엇을 선택해야 할까요?
