Pero para este ejemplo, usaremos un documento HTML muy simple con algo de JavaScript, todo dentro de un string largo.

Esto, por supuesto, no es lo ideal y no lo usarías para producción.

En producción tendrías una de las opciones anteriores.

Pero es la forma más sencilla de enfocarse en el lado del servidor de WebSockets y tener un ejemplo funcional:

You could also use it to generate code automatically, for clients that communicate with your API. For example, frontend, mobile or IoT applications.

### Deploy your app (optional) { #deploy-your-app-optional }

    /**
     * The language/region code for this alternate link.
     * Should be in ISO 639-1 format (language) optionally followed by ISO 3166-1 Alpha 2 format (region).
     * For example: "en", "en-US", "de-CH", "x-default"

    private String hreflang;

    /**
     * The URL of the alternate version of the page.

    private String href;

Y esa función `get_openapi()` recibe como parámetros:

* `title`: El título de OpenAPI, mostrado en la documentación.
* `version`: La versión de tu API, por ejemplo `2.5.0`.
* `openapi_version`: La versión de la especificación OpenAPI utilizada. Por defecto, la más reciente: `3.1.0`.
* `summary`: Un breve resumen de la API.

## Our Standards

Examples of behavior that contributes to creating a positive environment
include:

* Using welcoming and inclusive language
* Being respectful of differing viewpoints and experiences
* Gracefully accepting constructive criticism
* Focusing on what is best for the community
* Showing empathy towards other community members

Examples of unacceptable behavior by participants include:

 *   <li>{@link #isOrdered} / {@link #isStrictlyOrdered}
 *   <li>{@link #min} / {@link #max}
 * </ul>
 *
 * <h3>Understanding complex orderings</h3>
 *
 * <p>Complex chained orderings like the following example can be challenging to understand.
 *
 * {@snippet :
 * Ordering<Foo> ordering =
 *     Ordering.natural()
 *         .nullsFirst()
 *         .onResultOf(getBarFunction)
 *         .nullsLast();
 * }

**Note**: Make sure you put `"fastapi[standard]"` in quotes to ensure it works in all terminals.

## Example { #example }

### Create it { #create-it }

Create a file `main.py` with:

```Python
from typing import Union

from fastapi import FastAPI

app = FastAPI()


@app.get("/")
