Zaɓa bisa **wanda ke amfani da API da yadda buƙatun bayanansu suke bambanta** — ba bisa hype ba. GraphQL yana lashe lokacin da abokan ciniki daban-daban da yawa suke buƙatar tsara bayanansu kansu; REST yana lashe lokacin da buƙatu suke daidai, masu iya-caching, kuma masu sauƙi.

## Zaɓi GraphQL lokacin da

- **Abokan ciniki da yawa da bukatu daban-daban** — web, iOS, Android kowanne yana son filaye daban-daban daga daftari iri ɗaya. GraphQL yana kashe over/under-fetching don kada ka aika sabon endpoint kowane allo.
- **Bayanai masu zurfin dangantaka/kama-graph** — tambaya guda tana bin dangantaka (`user -> posts -> comments`) maimakon zagayowar REST N.
- **Sauyawar samfur mai sauri** — juyawar schema ta ƙari yana barin ƙungiyoyin frontend su ƙara filaye ba tare da jira sabbin backend endpoints ko versions ba.
- **Tara microservices** — gateway na federation yana gabatar da graph guda a kan ayyuka da yawa (tsarin BFF).

## Zaɓi REST lokacin da

- **Albarkatu masu sauƙi, masu daidaituwa** da damar da ake iya tsammani — CRUD inda kowane abokin ciniki yake son siffa iri ɗaya.
- **HTTP caching / CDN sun fi muhimmanci** — tsarin URL + `GET` na REST yana caching cikin sauƙi a kowane matakin; GraphQL yana buƙatar persisted queries don kusanta.
- **Ɗora/saukar fayiloli, binary, ko public APIs** inda kayan aiki masu faɗi, status codes, da sauƙi suke lashe.
- **Ƙaramar ƙungiya / ƙananan rikitarwa** — tsadar GraphQL a gefen uwar garke (resolvers, sarrafa N+1, iyakar tsadar tambaya, kayan aikin schema) bai cancanci ga ƴan endpoints kaɗan ba.

## Teburin ciniki na gaskiya

| Damuwa | GraphQL | REST |
|---|---|---|
| Over/under-fetching | An warware ta ƙira | Matsala ta kowa |
| HTTP/CDN caching | Wahala (na buƙatar aiki) | Na asali kuma mai sauƙi |
| Sarrafa tsadar tambaya/DoS | Dole ka ƙara shi | Mai iyaka a zahiri |
| Sassaucin abokin ciniki | Babba | Ƙarami |
| Rikitarwar uwar garke | Mafi girma | Mafi ƙasa |

Su ma ba masu keɓancewa ba ne — tsarukan da yawa suna bayyana REST don public/cacheable endpoints da GraphQL don abokan ciniki na ciki masu wadata.

## Me ya sa yake da muhimmanci

Masu tambayoyin hira na senior suna gwada **hukunci, ba biyayya ba**. Ƙarfin amsar tana ambaton axes — bambancin abokin ciniki, buƙatun caching, balagar ƙungiya, saman DoS — kuma tana yarda da ainihin tsadar GraphQL (caching da sarrafa tsadar tambaya) maimakon sayar da shi a matsayin mafi kyau a ko'ina.

Damuwa	GraphQL	REST
Over/under-fetching	An warware ta ƙira	Matsala ta kowa
HTTP/CDN caching	Wahala (na buƙatar aiki)	Na asali kuma mai sauƙi
Sarrafa tsadar tambaya/DoS	Dole ka ƙara shi	Mai iyaka a zahiri
