Et c'est le même niveau de performance que celui obtenu avec **FastAPI**.

Mit **FastAPI** bekommen Sie alles von **Starlette** (da FastAPI nur Starlette auf Steroiden ist):

* Schwer beeindruckende Performanz. Es ist <a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank">eines der schnellsten Python-Frameworks, auf Augenhöhe mit **NodeJS** und **Go**</a>.
* **WebSocket**-Unterstützung.
* Hintergrundaufgaben im selben Prozess.

E esse é o mesmo nível de performance que você tem com o **FastAPI**.

"""FastAPI framework, high performance, easy to learn, fast to code, ready for production"""

__version__ = "0.111.0"

from starlette import status as status

from .datastructures import UploadFile as UploadFile
from .exceptions import HTTPException as HTTPException
from .exceptions import WebSocketException as WebSocketException

        self.call = call
        self.use_cache = use_cache
        # Store the path to be able to re-generate a dependable from it in overrides
        self.path = path
        # Save the cache key at creation to optimize performance

Por exemplo:

pydantic>=1.2.0,<2.0.0
```

## Docker

Nessa seção você verá instruções e _links_ para guias de saber como:

* Fazer uma imagem/container da sua aplicação **FastAPI** com máxima performance. Em aproximadamente **5 min**.
* (Opcionalmente) entender o que você, como desenvolvedor, precisa saber sobre HTTPS.

    So, behind the scenes, it will actually work as if everything was the same single app.

!!! check
    You don't have to worry about performance when including routers.

    This will take microseconds and will only happen at startup.

    So it won't affect performance. ⚡

### Include an `APIRouter` with a custom `prefix`, `tags`, `responses`, and `dependencies`

* API-Annotationen und automatische Dokumentation

Und Sie müssen sie nur einmal deklarieren.

`FastAPI`は実際には`Starlette`のサブクラスです。したがって、Starletteをすでに知っているか使用している場合は、ほとんどの機能が同じように機能します。

**FastAPI**を使用すると、以下のような、**Starlette**のすべての機能を利用できます（FastAPIはStarletteを強化したものにすぎないため）:

* 見事なパフォーマンス。<a href="https://github.com/encode/starlette#performance" class="external-link" target="_blank"> **NodeJS**および**Go**に匹敵する、最速のPythonフレームワークの1つです。</a>

* **WebSocket**のサポート
* **GraphQL**のサポート
* プロセス内バックグラウンドタスク
* 起動およびシャットダウンイベント
* `httpx`に基づいて構築されたテストクライアント
