In Magento 2, is it possible to generate an HTTP path to a module's front-end asset files (CSS, Javascript) using PHP?

i.e. I know it's possible to add code like the following to a layout handle XML file

<css src="foo/baz/bar.css"/>
<link src="Magento_Sales::js/bootstrap/order-create-index.js"/>

What I'm curious about is do these layout directives have direct PHP equivalents? If so, what are they. If not, is there a reasonable technique for stabling reproducing their behavior via PHP?


I dug through the layout rendering code and found the answer to this one myself. You can use a Magento\Framework\View\Asset\Repository to create asset objects, and then use the asset objects to get a URL.

That is, inject the Magento\Framework\View\Asset\Repository repository via automatic constructor dependency injection.

protected $assetRepository;
public function __construct(
    \Magento\Framework\View\Asset\Repository $assetRepository
    $this->assetRepository = $assetRepository;

Use the asset repository to create an asset object

$asset = $this->assetRepository->createAsset('Vendor_Module::path/to/file.js')

and then use the asset object to get a URL

echo $asset->getUrl();

I'm not sure if there is a direct PHP equivalent but you can do this in a block very easily

$this->getViewFileUrl() . '/' . $this->getModuleName()

This will give you a path like this


And of course you can leave out the module name if you want to get a theme resource.

Not sure if it is what you are looking for, but take a look on Magento\Framework\View\Page\Config public methods.

You can use also like this create the object of assets Repository

$objectManager = \Magento\Framework\App\ObjectManager::getInstance();

$_assetRepo = $objectManager->create('Magento\Framework\View\Asset\Repository');

echo $_assetRepo->getUrl("Globaliasoft_Banner::images/t1.png");

use your module name instead of Globaliasoft_Banner.
