### The main app file

Now we create a dependency that returns a new `config.Settings()`.

Copy that to a file `main.py`.

Run the live server:

<div class="termy">

```console
$ <font color="#4E9A06">fastapi</font> dev <u style="text-decoration-style:single">main.py</u>
<font color="#3465A4">INFO    </font> Using path <font color="#3465A4">main.py</font>

RUN pip install --no-cache-dir --upgrade -r /code/requirements.txt

# (1)
COPY ./main.py /code/

# (2)
CMD ["fastapi", "run", "main.py", "--port", "80"]
```

1. Copy the `main.py` file to the `/code` directory directly (without any `./app` directory).

2. Use `fastapi run` to serve your application in the single file `main.py`.

        String quotedRootProjectDir = quote(rootProjectDir);
        String perfTestClasspathPattern = "(?:-cp.+\\\\build\\\\tmp\\\\performance-test-files.+?" + GRADLE_MAIN_CLASS_PATTERN_STR + ")";
        String buildDirClasspathPattern = "(?:-(classpath|cp) \"?" + quotedRootProjectDir + ".+?" + GRADLE_MAIN_CLASS_PATTERN_STR + ")";
        String playServerPattern = "(?:-classpath.+" + quotedRootProjectDir + ".+?" + PLAY_SERVER_PATTERN_STR + ")";

* `main`: plik `main.py` ("moduł" w Pythonie).
* `app`: obiekt stworzony w `main.py` w lini `app = FastAPI()`.
* `--reload`: spraw by serwer resetował się po każdej zmianie w kodzie. Używaj tego tylko w środowisku deweloperskim.

* `main`: файл `main.py` (модуль Python).
* `app`: объект, созданный внутри `main.py` с помощью строки `app = FastAPI()`.
* `--reload`: перезапуск сервера после изменения кода. Делайте это только во время разработки.
