## Nützliche Standards, alternative Dokumentation { #standards-based-benefits-alternative-documentation }

Und weil das generierte Schema vom [OpenAPI](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md)-Standard kommt, gibt es viele kompatible Tools.

## Dependencies

FastAPI depends on Pydantic and Starlette.

### `standard` Dependencies

When you install FastAPI with `pip install "fastapi[standard]"` it comes with the `standard` group of optional dependencies:

Used by Pydantic:

* [`email-validator`](https://github.com/JoshData/python-email-validator) - for email validation.

### Just Modern Python { #just-modern-python }

It's all based on standard **Python type** declarations (thanks to Pydantic). No new syntax to learn. Just standard modern Python.

If you need a 2 minute refresher of how to use Python types (even if you don't use FastAPI), check the short tutorial: [Python Types](python-types.md).

You write standard Python with types:

```Python
from datetime import date

Es war beispielsweise klar, dass es idealerweise auf Standard-Python-Typhinweisen basieren sollte.

Der beste Ansatz bestand außerdem darin, bereits bestehende Standards zu nutzen.

Örneğin Uvicorn'u kurmak için:

<div class="termy">

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

---> 100%
```

</div>

Benzer bir süreç, diğer ASGI server programlarının tamamı için de geçerlidir.

/// tip | İpucu

`standard` eklediğinizde Uvicorn, önerilen bazı ek bağımlılıkları kurar ve kullanır.

Notice that the path parameter is declared to be an integer.

## Standards-based benefits, alternative documentation { #standards-based-benefits-alternative-documentation }

And because the generated schema is from the [OpenAPI](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md) standard, there are many compatible tools.

<div class="termy">

```console
$ pip install "fastapi[standard]"

---> 100%
```

</div>

/// note | Remarque

Lorsque vous installez avec `pip install "fastapi[standard]"`, cela inclut des dépendances standards optionnelles par défaut, y compris `fastapi-cloud-cli`, qui vous permet de déployer sur [FastAPI Cloud](https://fastapicloud.com).

## Dépendances { #dependencies }

FastAPI dépend de Pydantic et Starlette.

### Dépendances `standard` { #standard-dependencies }

Lorsque vous installez FastAPI avec `pip install "fastapi[standard]"`, il inclut le groupe `standard` de dépendances optionnelles :

Utilisées par Pydantic :

Por ejemplo, para instalar Uvicorn:

<div class="termy">

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

---> 100%
```

</div>

Un proceso similar se aplicaría a cualquier otro programa de servidor ASGI.

/// tip | Consejo

Al añadir `standard`, Uvicorn instalará y usará algunas dependencias adicionales recomendadas.
