# Generating SDKs { #generating-sdks }

Because **FastAPI** is based on the **OpenAPI** specification, its APIs can be described in a standard format that many tools understand.

This makes it easy to generate up-to-date **documentation**, client libraries (<abbr title="Software Development Kits">**SDKs**</abbr>) in multiple languages, and **testing** or **automation workflows** that stay in sync with your code.

# External Links

**FastAPI** has a great community constantly growing.

There are many posts, articles, tools, and projects, related to **FastAPI**.

## `uvicorn` 호출 { #call-uvicorn }

FastAPI 애플리케이션에서 `uvicorn`을 직접 임포트하여 실행합니다:

{* ../../docs_src/debugging/tutorial001_py310.py hl[1,15] *}

### `__name__ == "__main__"` 에 대하여 { #about-name-main }

`__name__ == "__main__"`의 주요 목적은 다음과 같이 파일이 호출될 때 실행되는 일부 코드를 갖는 것입니다.

<div class="termy">

```console
$ python myapp.py
```

</div>

그러나 다음과 같이 다른 파일을 가져올 때는 호출되지 않습니다.

# Sub Applications - Mounts { #sub-applications-mounts }

If you need to have two independent FastAPI applications, with their own independent OpenAPI and their own docs UIs, you can have a main app and "mount" one (or more) sub-application(s).

## Mounting a **FastAPI** application { #mounting-a-fastapi-application }

// we update the version property to reflect if we are building a snapshot or a release build
// we write this back out below to load it in the Build.java which will be shown in rest main action
// to indicate this being a snapshot build or a release build.
Properties props = VersionPropertiesLoader.loadBuildSrcVersion(project.file('version.properties'), project.getProviders())

Por ejemplo, podrías tener un archivo `config.py` con:

{* ../../docs_src/settings/app01_py310/config.py *}

Y luego usarlo en un archivo `main.py`:

{* ../../docs_src/settings/app01_py310/main.py hl[3,11:13] *}

/// tip | Consejo

También necesitarías un archivo `__init__.py` como viste en [Aplicaciones Más Grandes - Múltiples Archivos](../tutorial/bigger-applications.md).

RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt

# (1)!
COPY ./main.py /code/

# (2)!
CMD ["fastapi", "run", "main.py", "--port", "80"]
```

1. Copia el archivo `main.py` directamente al directorio `/code` (sin ningún directorio `./app`).

2. Usa `fastapi run` para servir tu aplicación en el archivo único `main.py`.
