Symfony: How to render a template as a simple txt - php

Question

I have to render a template of an action as a simple .txt file.
How can I do this? Is there a way other than using the Response object?
Using a Response object:
$content = $this->get('templating')->render(
'AppBundle:Company:accountBillingInvoice.txt.twig',
[
'invoice' => 'This is the invoice'
]
);
$response = new Response($content , 200);
$response->headers->set('Content-Type', 'text/plain');

I can't see what's wrong with using the Response object - it's pretty simple!
If you want to render text responses from many controller actions and you don't want to repeat yourself a lot, you can define some service class that builds up the response for you, like:
class TextResponseRenderer
{
/** #var EngineInterface */
private $engine;
// constructor...
/**
* #param string $template The name of the twig template to be rendered.
* #param array $parameters The view parameters for the template.
* #return Response The text response object with the content and headers set.
*/
public function renderResponse(string $template, array $parameters): Response
{
$content = $this->engine->render($template, $parameters);
$textResponse = new Response($content , 200);
$textResponse->headers->set('Content-Type', 'text/plain');
return $textResponse;
}
}
Other option may be writing a listener for the kernel.response that modifies the response headers, but this might be over-complicating things. See more info here.
