Puedes definir manejadores de eventos (funciones) que necesitan ser ejecutadas antes de que la aplicación se inicie, o cuando la aplicación se está cerrando.

Estas funciones pueden ser declaradas con `async def` o `def` normal.

### Evento `startup` { #startup-event }

Para añadir una función que debería ejecutarse antes de que la aplicación inicie, declárala con el evento `"startup"`:

Bu fonksiyon bir `GET` işlemi kullanılarak "`/`" bağlantısına bir istek geldiğinde **FastAPI** tarafından çağrılır.

Bu durumda bu fonksiyon bir `async` fonksiyondur.

---

Bu fonksiyonu `async def` yerine normal bir fonksiyon olarak da tanımlayabilirsiniz.

We'll discuss the `@lru_cache` in a bit.

For now you can assume `get_settings()` is a normal function.

///

And then we can require it from the *path operation function* as a dependency and use it anywhere we need it.
