# GraphQL

As **FastAPI** is based on the **ASGI** standard, it's very easy to integrate any **GraphQL** library also compatible with ASGI.

You can combine normal FastAPI *path operations* with GraphQL on the same application.

!!! tip
    **GraphQL** solves some very specific use cases.

    It has **advantages** and **disadvantages** when compared to common **web APIs**.

# GraphQL

Da **FastAPI** auf dem **ASGI**-Standard basiert, ist es sehr einfach, jede **GraphQL**-Bibliothek zu integrieren, die auch mit ASGI kompatibel ist.

Sie können normale FastAPI-*Pfadoperationen* mit GraphQL in derselben Anwendung kombinieren.

!!! tip "Tipp"
    **GraphQL** löst einige sehr spezifische Anwendungsfälle.

    Es hat **Vorteile** und **Nachteile** im Vergleich zu gängigen **Web-APIs**.

    **FastAPI** herhangi bir özel amacı veya anlamı olması konusunda ısrarcı olmaz.

    Buradaki bilgiler bir gereklilik değil, bir kılavuz olarak sunulmaktadır.

    Mesela GraphQL kullanırkan genelde tüm işlemleri yalnızca `POST` operasyonunu kullanarak gerçekleştirirsiniz.

### Adım 4: **Yol Operasyonu Fonksiyonunu** Tanımlayın

Aşağıdaki, bizim **yol operasyonu fonksiyonumuzdur**:

* **WebSocket** desteği.
* **GraphQL** desteği.
* Kullanım halinde arka plan işlevleri.
* Başlatma ve kapatma eventleri(startup and shutdown).
* Test sunucusu HTTPX üzerine kurulu.
* **CORS**, GZip, Static dosyalar, Streaming responseları.

    **FastAPI** no impone ningún significado específico.

    La información que está presentada aquí es una guía, no un requerimiento.

    Por ejemplo, cuando usas GraphQL normalmente realizas todas las acciones usando únicamente operaciones `POST`.

### Paso 4: define la **función de la operación de path**

Esta es nuestra  "**función de la operación de path**":

* **path**: es `/`.
