Starlette (и **FastAPI**) основаны на <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>, что делает их совместимыми как со стандартной библиотекой <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a> в Python, так и с <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a>.<!--http://new.gramota.ru/spravka/buro/search-answer?s=285295-->

Você verá a documentação automática da API para a aplicação principal, incluindo apenas suas próprias _operações de rota_:

E então, abra a documentação para a sub-aplicação, em <a href="http://127.0.0.1:8000/subapi/docs" class="external-link" target="_blank">http://127.0.0.1:8000/subapi/docs</a>.

Por defecto, **FastAPI** convertiría automáticamente ese valor de retorno a JSON usando el `jsonable_encoder` explicado en [JSON Compatible Encoder](../tutorial/encoder.md){.internal-link target=_blank}.

Luego, detrás de escena, pondría esos datos compatibles con JSON (por ejemplo, un `dict`) dentro de un `JSONResponse` que se usaría para enviar el response al cliente.

Standardmäßig konvertiert **FastAPI** diesen Rückgabewert automatisch nach JSON, mithilfe des `jsonable_encoder`, der in [JSON-kompatibler Encoder](../tutorial/encoder.md){.internal-link target=_blank} erläutert wird.

Dann würde es hinter den Kulissen diese JSON-kompatiblen Daten (z. B. ein `dict`) in eine `JSONResponse` einfügen, die zum Senden der Response an den Client verwendet würde.
