### Using your local FastAPI

If you create a Python file that imports and uses FastAPI, and run it with the Python from your local environment, it will use your cloned local FastAPI source code.

And if you update that local FastAPI source code when you run that Python file again, it will use the fresh version of FastAPI you just edited.

That way, you don't have to "install" your local version to be able to test every change.

$ python -m venv env
```

### Ativar o ambiente

Ative o novo ambiente com:

=== "Linux, macOS"

    <div class="termy">

    ```console
    $ source ./env/bin/activate
    ```

    </div>

=== "Windows PowerShell"

    <div class="termy">

    ```console
    $ .\env\Scripts\Activate.ps1
    ```

    </div>

=== "Windows Bash"

We get the same response:

```JSON
{
    "message": "Hello World",
    "root_path": "/api/v1"
}
```

but this time at the URL with the prefix path provided by the proxy: `/api/v1`.

Of course, the idea here is that everyone would access the app through the proxy, so the version with the path prefix `/api/v1` is the "correct" one.
