You can use any template engine you want with **FastAPI**.

A common choice is Jinja2, the same one used by Flask and other tools.

There are utilities to configure it easily that you can use directly in your **FastAPI** application (provided by Starlette).

## Install dependencies { #install-dependencies }

Make sure you create a [virtual environment](../virtual-environments.md){.internal-link target=_blank}, activate it, and install `jinja2`:

And to communicate using WebSockets with your backend you would probably use your frontend's utilities.

Or you might have a native mobile application that communicates with your WebSocket backend directly, in native code.

Or you might have any other way to communicate with the WebSocket endpoint.

/// warning | Uyarı

*Yol operasyonları* içerisinde birden fazla `Form` parametresi tanımlayabilirsiniz ancak bunlarla birlikte JSON verisi kabul eden `Body` alanları tanımlayamazsınız çünkü bu durumda istek gövdesi `application/json` yerine `application/x-www-form-urlencoded` ile kodlanmış olur.

Bu **FastAPI**'ın getirdiği bir kısıtlama değildir, HTTP protokolünün bir parçasıdır.

## Özet

<span style="color: green;">INFO</span>:     Started server process [28722]
<span style="color: green;">INFO</span>:     Waiting for application startup.
<span style="color: green;">INFO</span>:     Application startup complete.
```

</div>

**ДУЖЕ радимо** написати або скопіювати код, відредагувати його та запустити локально.

            mimeType = "text/html";
        } else if (response instanceof JsonResponse) {
            mimeType = "application/json";
        } else if (response instanceof XmlResponse) {
            mimeType = "text/xml";
        } else if (response instanceof StreamResponse) {
            mimeType = "application/octet-stream";
        } else {
            logger.debug("Unknown response: {}", response);
            return;

Sie können mehrere `Form`-Parameter in einer *Pfadoperation* deklarieren, aber Sie können nicht gleichzeitig auch `Body`-Felder deklarieren, welche Sie als JSON erwarten, da der Request den Body mittels `application/x-www-form-urlencoded` statt `application/json` kodiert.

Das ist keine Limitation von **FastAPI**, sondern Teil des HTTP-Protokolls.

## Zusammenfassung

# Debugging { #debugging }

You can connect the debugger in your editor, for example with Visual Studio Code or PyCharm.

## Call `uvicorn` { #call-uvicorn }

In your FastAPI application, import and run `uvicorn` directly:

{* ../../docs_src/debugging/tutorial001.py hl[1,15] *}

### About `__name__ == "__main__"` { #about-name-main }

The main purpose of the `__name__ == "__main__"` is to have some code that is executed when your file is called with:

<span style="color: green;">INFO</span>:     Started server process [28722]
<span style="color: green;">INFO</span>:     Waiting for application startup.
<span style="color: green;">INFO</span>:     Application startup complete.
```

</div>

/// note | Технические детали

Команда `uvicorn main:app` обращается к:

* `main`: файл `main.py` (модуль Python).
