* Select "Python"
* Run the debugger with the option "`Python: Current File (Integrated Terminal)`".

It will then start the server with your **FastAPI** code, stop at your breakpoints, etc.

Here's how it might look:

If you use Pycharm, you can:

* Open the "Run" menu.
* Select the option "Debug...".
* Then a context menu shows up.

      NOTE: It's also possible to switch to offline mode on a per-build basis, using the '-o' command-line option.

      <syntax>settings.interactiveMode</syntax>
      <configuration>
        <![CDATA[
    <interactiveMode>true</interactiveMode>
    ]]></configuration>

To achieve this, you can use the command line option `--root-path` like:

<div class="termy">

```console
$ fastapi run main.py --forwarded-allow-ips="*" --root-path /api/v1

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)
```

</div>

If you use Hypercorn, it also has the option `--root-path`.

/// warning | Achtung

Denken Sie daran, die Option `--reload` zu entfernen, wenn Sie diese verwendet haben.

Die Option `--reload` verbraucht viel mehr Ressourcen, ist instabiler, usw.

Sie hilft sehr während der **Entwicklung**, aber Sie sollten sie **nicht** in der **Produktion** verwenden.
