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**.

Make sure you evaluate if the **benefits** for your use case compensate the **drawbacks**. 🤓

### <a href="https://requests.readthedocs.io" class="external-link" target="_blank">Requests</a>

**FastAPI** is not actually an alternative to **Requests**. Their scope is very different.

It would actually be common to use Requests *inside* of a FastAPI application.

But still, FastAPI got quite some inspiration from Requests.

/// info | "`@decorator` Information"

Diese `@something`-Syntax wird in Python „Dekorator“ genannt.

Sie platzieren ihn über einer Funktion. Wie ein hübscher, dekorativer Hut (daher kommt wohl der Begriff).

Ein „Dekorator“ nimmt die darunter stehende Funktion und macht etwas damit.

Sie können auch `from starlette.responses import HTMLResponse` verwenden.

**FastAPI** bietet dieselben `starlette.responses` auch via `fastapi.responses` an, als Annehmlichkeit für Sie, den Entwickler. Die meisten verfügbaren Responses kommen aber direkt von Starlette.

### Mehrere Datei-Uploads mit zusätzlichen Metadaten

Und so wie zuvor können Sie `File()` verwenden, um zusätzliche Parameter zu setzen, sogar für `UploadFile`:
