## デバッガーでコードを実行

コードから直接Uvicornサーバーを実行しているため、デバッガーから直接Pythonプログラム (FastAPIアプリケーション) を呼び出せます。

---

例えば、Visual Studio Codeでは、次のことが可能です:

* 「デバッグ」パネルに移動。
* 「構成の追加...」
* 「Python」を選択。
* オプション「`Python: Current File (Integrated Terminal)`」を指定してデバッガーを実行。

すると、**FastAPI** コードでサーバーが起動され、ブレークポイントで停止したりするでしょう。

以下の様な画面になります:

Pycharmを使用する場合、次のことが可能です:

     *
     * @return the start time as an Instant object, never {@code null}
     */
    @Nonnull
    Instant getStartTime();

    /**
     * Gets the directory of the topmost project being built, usually the current directory or the
     * directory pointed at by the {@code -f/--file} command line argument.
     *
     * @return the directory of the topmost project, never {@code null}
     * @see Project#isTopProject()

        return _instance;
    }

    //                                                                       =============
    @Override
    public String getProjectName() {
        return null;
    }

    @Override

}
```
