## Recursos do Starlette { #starlette-features }

**FastAPI** é totalmente compatível com (e baseado no) <a href="https://www.starlette.dev/" class="external-link" target="_blank"><strong>Starlette</strong></a>. Então, qualquer código adicional Starlette que você tiver, também funcionará.

`FastAPI` é na verdade uma sub-classe do `Starlette`. Então, se você já conhece ou usa Starlette, a maioria das funcionalidades se comportará da mesma forma.

Alle Kern-Webaspekte zu handhaben. Und fügt Funktionen obenauf.

Die Klasse `FastAPI` selbst erbt direkt von der Klasse `Starlette`.

Alles, was Sie also mit Starlette machen können, können Sie direkt mit **FastAPI** machen, da es sich im Grunde um Starlette auf Steroiden handelt.

## Eine „aufrufbare“ Instanz { #a-callable-instance }

In Python gibt es eine Möglichkeit, eine Instanz einer Klasse <abbr title="Englisch „callable“">„aufrufbar“</abbr> zu machen.

Nicht die Klasse selbst (die bereits aufrufbar ist), sondern eine Instanz dieser Klasse.

Dazu deklarieren wir eine Methode `__call__`:

Você também pode usar:

* `response_model_exclude_defaults=True`
* `response_model_exclude_none=True`

Você pode definir `"json_schema_extra"` com um `dict` contendo quaisquer dados adicionais que você queira que apareçam no JSON Schema gerado, incluindo `examples`.
