## Gunicorn und Uvicorn installieren

<div class="termy">

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

---> 100%
```

</div>

Dadurch wird sowohl Uvicorn mit zusätzlichen `standard`-Packages (um eine hohe Leistung zu erzielen) als auch Gunicorn installiert.

### Resumen

En resumen, declaras los tipos de parámetros, body, etc. **una vez** como parámetros de la función.

Lo haces con tipos modernos estándar de Python.

No tienes que aprender una sintaxis nueva, los métodos o clases de una library específica, etc.

Solo **Python** estándar.

Por ejemplo, para un `int`:

```Python
item_id: int
```

o para un modelo más complejo de `Item`:

```Python

                        Lists.newLinkedList(asList(elements)));
                  }
                })
            .named("ForwardingCollection[LinkedList] with standard implementations")
            .withFeatures(
                CollectionSize.ANY,
                CollectionFeature.ALLOWS_NULL_VALUES,
                CollectionFeature.GENERAL_PURPOSE)
            .createTestSuite());

// PriorityClass defines mapping from a priority class name to the priority

ASGI ist ein neuer „Standard“, welcher von Mitgliedern des Django-Kernteams entwickelt wird. Es handelt sich immer noch nicht um einen „Python-Standard“ (ein PEP), obwohl sie gerade dabei sind, das zu tun.

      "number_of_replicas": 0,
      "auto_expand_replicas": "0-1"
    },

  }

By using them, you can take advantage of all these standard-based tools, including these interactive documentation systems.

OpenAPI defines the following security schemes:

* `apiKey`: an application specific key that can come from:
    * A query parameter.
    * A header.
    * A cookie.
* `http`: standard HTTP authentication systems, including:

/// tip | "豆知識"

`standard` を加えることで、Uvicornがインストールされ、いくつかの推奨される依存関係を利用するようになります。

これには、`asyncio` の高性能な完全互換品である `uvloop` が含まれ、並行処理のパフォーマンスが大幅に向上します。

  The "source code" for a work means the preferred form of the work
for making modifications to it.  "Object code" means any non-source
form of a work.

  A "Standard Interface" means an interface that either is an official
standard defined by a recognized standards body, or, in the case of
interfaces specified for a particular programming language, one that
is widely used among developers working in that language.
