<summary><code>fastapi dev</code> コマンドについて</summary>

`fastapi dev` コマンドは `main.py` ファイルを自動的に読み取り、その中の **FastAPI** アプリを検出し、[Uvicorn](https://www.uvicorn.dev) を使用してサーバーを起動します。

デフォルトでは、`fastapi dev` はローカル開発向けに自動リロードを有効にして起動します。

詳しくは [FastAPI CLI docs](https://fastapi.tiangolo.com/ja/fastapi-cli/) を参照してください。
