l'application efficacement et sans interruption ni problème.

Ceci contraste avec les étapes de **développement**, où vous êtes constamment en train de modifier le code, de le casser
et de le réparer, d'arrêter et de redémarrer le serveur de développement, _etc._

## Stratégies de déploiement

Il existe plusieurs façons de procéder, en fonction de votre cas d'utilisation spécifique et des outils que vous

    pip install fastapi
    ```

    Também instale o `uvicorn` para funcionar como servidor:

    ```
    pip install "uvicorn[standard]"
    ```

    E o mesmo para cada dependência opcional que você quiser usar.

## Guia Avançado de Usuário

Há também um **Guia Avançado de Usuário** que você pode ler após esse **Tutorial - Guia de Usuário**.

## À propos de Starlette

Vous ne devriez pas épingler la version de `starlette`.

Différentes versions de **FastAPI** utiliseront une version spécifique plus récente de Starlette.

Ainsi, vous pouvez simplement laisser **FastAPI** utiliser la bonne version de Starlette.

## À propos de Pydantic

Pydantic inclut des tests pour **FastAPI** avec ses propres tests, ainsi les nouvelles versions de Pydantic (au-dessus
