Definition

A query language for APIs that lets clients request exactly the data they need in a single request.

لغة استعلام لواجهات برمجة التطبيقات تتيح للعملاء طلب البيانات التي يحتاجونها تحديدًا في طلب واحد.

Why It Matters

Supabase (an alternative to Firebase) automatically exposes a GraphQL API for your PostgreSQL tables. Understanding GraphQL helps you leverage this if 404Fault ever adds Supabase.

Supabase (بديل Firebase) يُعرض تلقائيًا GraphQL API لجداول PostgreSQL. فهم GraphQL يساعدك على الاستفادة من هذا إذا أضافت 404Fault Supabase في المستقبل.

Full Definition

GraphQL is an API query language (and runtime) where clients define the shape of data they want. A single `/graphql` endpoint handles all queries and mutations. Benefits: no over-fetching (only get what you ask for), strongly typed schema, self-documenting. Tradeoffs: more complex than REST, harder to cache. Supabase exposes a GraphQL API automatically. Apollo Client is the standard GraphQL client for React.
GraphQL لغة استعلام API (وبيئة تشغيل) يُحدّد فيها العملاء شكل البيانات التي يريدونها. نقطة نهاية واحدة `/graphql` تتعامل مع جميع الاستعلامات والتحويلات. المزايا: لا over-fetching، مخطط بنوع قوي، توثيق ذاتي.

Example Usage

“query { glossaryTerms(where: { difficulty: { _eq: 'beginner' } }, orderBy: { nameEn: asc }) { slug nameEn shortDefinitionEn } }”

“query { glossaryTerms(where: { difficulty: { _eq: 'beginner' } }, orderBy: { nameEn: asc }) { slug nameEn shortDefinitionEn } }”
