To accomplish this, new methods has been added to :php:`\TYPO3\CMS\Core\Page\AssetCollector`: - :php:`hasJavaScript(string $identifier): bool` - :php:`hasInlineJavaScript(string $identifier): bool` - :php:`hasStyleSheet(string $identifier): bool` - :php:`hasInlineStyleSheet(string $identifier): bool` - :php:`hasMedia(string $identifier): bool` .. code-block:: php //use TYPO3\CMS\Core\Page\AssetCollector; //use TYPO3\CMS\Core\Utility\GeneralUtility; $assetsCollector = GeneralUtility::makeInstance(AssetCollector::class); if ($assetsCollector->hasJavaScript($identifier)) { // result: true - javascript with identifier $identifier exists } else { // result: false - javascript with identifier $identifier do not exists } // $result is true if $identifier exists, otherwise false. $result1 = $assetsCollector->hasJavaScript($identifier); $result2 = $assetsCollector->hasInlineJavaScript($identifier); $result3 = $assetsCollector->hasStyleSheet($identifier); $result4 = $assetsCollector->hasInlineStyleSheet($identifier); $result5 = $assetsCollector->hasMedia($identifier); Impact ====== Users have the ability to check if the asset already exists before regenerating it, thus avoiding redundancy. .. index:: PHP-API, ext:core
