/// tip

Notice that here as we are using standard `open()` that doesn't support `async` and `await`, we declare the path operation with normal `def`.

///

### `FileResponse` { #fileresponse }

Asynchronously streams a file as the response.

Takes a different set of arguments to instantiate than the other response types:

* `path` - The file path to the file to stream.

/// tip | Tipp

Beachten Sie, dass wir, da wir Standard-`open()` verwenden, welches `async` und `await` nicht unterstützt, hier die Pfadoperation mit normalen `def` deklarieren.

///

### `FileResponse` { #fileresponse }

Streamt eine Datei asynchron als Response.

Nimmt zur Instanziierung einen anderen Satz von Argumenten entgegen als die anderen Response-Typen:

/// tip | Consejo

Nota que aquí como estamos usando `open()` estándar que no admite `async` y `await`, declaramos el path operation con `def` normal.

///

### `FileResponse` { #fileresponse }

Transmite un archivo asincrónicamente como response.

Toma un conjunto diferente de argumentos para crear un instance que los otros tipos de response:

/// tip | Совет

Заметьте, что здесь мы используем стандартный `open()`, который не поддерживает `async` и `await`, поэтому объявляем операцию пути обычной `def`.

///

### `FileResponse` { #fileresponse }

Асинхронно отправляет файл как ответ.

Для создания экземпляра принимает иной набор аргументов, чем другие типы ответов:

- `path` — путь к файлу, который будет отправлен.
