**Typer**は FastAPI の弟分です。そして、**CLI 版 の FastAPI**を意味しています。

## 必要条件

FastAPI は巨人の肩の上に立っています。

Stellen Sie zunächst sicher, dass Sie Ihre [virtuelle Umgebung](../virtual-environments.md){.internal-link target=_blank} erstellt und aktiviert haben, und installieren Sie dann das Package `pydantic-settings`:

Qualquer função que possa ser utilizada com:

* <a href="https://docs.python.org/3/library/contextlib.html#contextlib.asynccontextmanager" class="external-link" target="_blank">`@contextlib.asynccontextmanager`</a>

pode ser utilizada como uma dependência do **FastAPI**.

Any function that is valid to use with:

* <a href="https://docs.python.org/3/library/contextlib.html#contextlib.asynccontextmanager" class="external-link" target="_blank">`@contextlib.asynccontextmanager`</a>

would be valid to use as a **FastAPI** dependency.

Starlette (и **FastAPI**) основаны на <a href="https://anyio.readthedocs.io/en/stable/" class="external-link" target="_blank">AnyIO</a>, что делает их совместимыми и со стандартной библиотекой Python <a href="https://docs.python.org/3/library/asyncio-task.html" class="external-link" target="_blank">asyncio</a>, и с <a href="https://trio.readthedocs.io/en/stable/" class="external-link" target="_blank">Trio</a>.
