Übergeben Sie der Funktion `*` als ersten Parameter.

```

---

Si votre application n'a pas à communiquer avec une bibliothèque externe et pas à attendre de réponse, utilisez `async def`.

---

Si vous ne savez pas, utilisez seulement `def` comme vous le feriez habituellement.

---

**Note** : vous pouvez mélanger `def` et `async def` dans vos *fonctions de chemin* autant que nécessaire, **FastAPI** saura faire ce qu'il faut avec.

* Auto-generate a "server" in OpenAPI `servers` when there's a `root_path` instead of prefixing all the `paths`:
    * Add a new parameter for `FastAPI` classes: `root_path_in_servers` to disable the auto-generation of `servers`.
    * New docs about `root_path` and `servers` in [Additional Servers](https://fastapi.tiangolo.com/advanced/behind-a-proxy/#additional-servers).

# Despliegue - Introducción

Desplegar una aplicación hecha con **FastAPI** es relativamente fácil.

## ¿Qué significa desplegar una aplicación?

**Desplegar** una aplicación significa realizar una serie de pasos para hacerla **disponible para los usuarios**.

For production you would use `fastapi run` instead. 🚀

Internally, **FastAPI CLI** uses <a href="https://www.uvicorn.org" class="external-link" target="_blank">Uvicorn</a>, a high-performance, production-ready, ASGI server. 😎

## `fastapi dev`

When you run `fastapi dev`, it will run on development mode.

And these models are all sharing a lot of the data and duplicating attribute names and types.

We could do better.

We can declare a `UserBase` model that serves as a base for our other models. And then we can make subclasses of that model that inherit its attributes (type declarations, validation, etc).

All the data conversion, validation, documentation, etc. will still work as normally.
