# 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**.
