### Executar o App { #run-the-app }

Você pode executar o app:

from enum import Enum
from typing import Any, TypeVar, Union

from pydantic import BaseModel
from pydantic.main import IncEx as IncEx

DecoratedCallable = TypeVar("DecoratedCallable", bound=Callable[..., Any])
UnionType = getattr(types, "UnionType", Union)
ModelNameMap = dict[type[BaseModel] | type[Enum], str]

def slow_sync_stream():
    yield {"n": 1}
    time.sleep(0.3)
    yield {"n": 2}


def test_keepalive_ping_async(monkeypatch: pytest.MonkeyPatch):
    monkeypatch.setattr(fastapi.routing, "_PING_INTERVAL", 0.05)
    with TestClient(keepalive_app) as c:
        response = c.get("/slow-async")
    assert response.status_code == 200
    text = response.text

Muchos desarrolladores y equipos ya dependen de **FastAPI** para sus proyectos (incluyéndome a mí y a mi equipo).

Pero aún así, hay muchas mejoras y funcionalidades por venir.

**FastAPI** tiene un gran futuro por delante.

# Detrás de un Proxy { #behind-a-proxy }

En muchas situaciones, usarías un **proxy** como Traefik o Nginx delante de tu app de FastAPI.

Estos proxies podrían manejar certificados HTTPS y otras cosas.
