Build Status Downloads this Month Latest stable Coverage Status

If you need the browser to automatically invalid it's cache, use this extension.

Install via composer:

$ composer require h4kuna/assets

Version 0.1.3 supports PHP 5.3. Newer versions support PHP of version 5.6 and higher.

How to use

For first step you only need to register the extension, other parameters are optional. You have available the new filter asset automatically.

	assetsExtension: h4kuna\Assets\DI\AssetsExtension

	# optional
	debugMode: %debugMode%
	tempDir: %tempDir% # If you want change temp dir.
	wwwTempDir: %wwwDir/temp% # here is place where move assets from 3rd library (from vendor/ etc.)
	    - %appDir%/../vendor/nette/nette.js # save to %wwwTempDir%/nette.js
        'ext/nette2.4.js': %appDir%/../vendor/nette/nette.js # save to %wwwTempDir%/ext/nette2.4.js

        # download from external source, this is experimental!
		- http://example.com/foo.js # save to %wwwTempDir%/foo.js
		'sha256-secure-token': http://example.com/foo.js # check if is right file


  • $basePath is not needed
  • path is relative to your wwwDir
  • cache is built when new file found, or if you remove %tempDir%/cache/_assets
  • behavior is the same in production and development environment
<link rel="stylesheet" href="{='css/main.css'|asset}">
<script src="{='js/main.js'|asset}"></script>

Example output: ?file mtime.

<link rel="stylesheet" href="/css/main.css?123456">
<script src="/js/main.js?456789"></script>

Printing absolute path to the template can be anabled using double slash:

<link rel="stylesheet" href="{='//css/main.css'|asset}">


Here is an object that can have dependency anything and collect css and js files for render to template.

/* @var $assets \h4kuna\Assets\Assets */
$assets->addJs('ext/nette2.4.js', ['async' => TRUE]);
echo (string) $assets->renderJs();

render this

<script src="/temp/ext/nette2.4.js?456789" async></script>

Custom cache builder - advanced usege

This creates the cache in the compile time. By default, assets cache is build on the fly:

	cacheBuilder: \CacheBuilder

Use prepared interface:

class CacheBuilder implements \h4kuna\Assets\DI\ICacheBuilder
	public function create(\h4kuna\Assets\CacheAssets $cache, $wwwDir)
		$finder = Nette\Utils\Finder::findFiles('*')->in($wwwDir . '/config');
		foreach ($finder as $file) {
			/* @var $file \SplFileInfo */

	private static function replaceSlashOnWindows(SplFileInfo $file)
		static $isWindows;
		if ($isWindows === NULL) {
			$isWindows = strtoupper(substr(PHP_OS, 0, 3)) === 'WIN';

		if ($isWindows) {
			return str_replace('\\', '/', $file->getPathname());
		return $file->getPathname();
