Disabling file compression in TYPO3 'be:container' - typo3

Question

I've been working around with the development of a TYPO3 extension. While designing the backend module I'd observed that my css and js external files which are included with,
<f:be.container loadJQuery="true" includeCssFiles="{0:'https://ajax.googleapis.com/****'}" includeJsFiles="{0:'https://ajax.googleapis.com/****'}" >
are getting compressed and as a result the design turning into a mess.
Compressing is a good act. I admit it. But how can avoid it in backend container or at least for external files.. ?? Wandering for the answer for 2 days.

Answer 1

From the code this is not easily possible with the be.container view helper (as it calls $pageRenderer->addCssFile directly, without options).
What you could do would be to add an own viewhelper exposing all the addCssFile options. As an example, your viewhelper could look like this:
class AddCssFileViewHelper extends AbstractViewHelper
{
/**
* #var PageRenderer
*/
protected $pageRenderer;
/**
* #param PageRenderer $pageRenderer
*/
public function injectPageRenderer(PageRenderer $pageRenderer)
{
$this->pageRenderer = $pageRenderer;
}
/**
* Initialize arguments.
*
* #throws \TYPO3Fluid\Fluid\Core\ViewHelper\Exception
*/
public function initializeArguments()
{
parent::initializeArguments();
$this->registerArgument('cssFile', 'string', 'path to your file', false, '');
$this->registerArgument('compress', 'bool', 'specifies whether to compress or not, default: true', false, true);
}
public function render()
{
$this->pageRenderer->addCssFile($this->arguments['cssFile'], 'stylesheet', 'all', '', $this->arguments['compress']);
}
}
