public AssetResolverInterface::getCssAssets(AttachedAssetsInterface $assets, $optimize) Returns the CSS assets for the current response's libraries. It returns the CSS assets in order, according to the SMACSS categories specified in the assets' weights: CSS_BASE CSS_LAYOUT CSS_COMPONENT CSS_STATE CSS_THEME This ensures proper cascading of styles so themes can easily override module styles through CSS selectors. Themes may replace module-defined CSS files by adding a stylesheet with the same f

public AssetResolverInterface::getJsAssets(AttachedAssetsInterface $assets, $optimize) Returns the JavaScript assets for the current response's libraries. References to JavaScript files are placed in a certain order: first, all 'core' files, then all 'module' and finally all 'theme' JavaScript files are added to the page. Then, all settings are output, followed by 'inline' JavaScript code. If running update.php, all preprocessing is disabled. Note that hook_js_alter(&$javascript) is called

public static AssetResolver::sort($a, $b) Sorts CSS and JavaScript resources. This sort order helps optimize front-end performance while providing modules and themes with the necessary control for ordering the CSS and JavaScript appearing on a page. Parameters $a: First item for comparison. The compared items should be associative arrays of member items. $b: Second item for comparison. Return value int File core/lib/Drupal/Core/Asset/AssetResolver.php, line 371 Class AssetResolver The de

protected AssetResolver::getJsSettingsAssets(AttachedAssetsInterface $assets) Returns the JavaScript settings assets for this response's libraries. Gathers all drupalSettings from all libraries in the attached assets collection and merges them. Parameters \Drupal\Core\Asset\AttachedAssetsInterface $assets: The assets attached to the current response. Return value array A (possibly optimized) collection of JavaScript assets. File core/lib/Drupal/Core/Asset/AssetResolver.php, line 194 Class

protected AssetResolver::getLibrariesToLoad(AttachedAssetsInterface $assets) Returns the libraries that need to be loaded. For example, with core/a depending on core/c and core/b on core/d: $assets = new AttachedAssets(); $assets->setLibraries(['core/a', 'core/b', 'core/c']); $assets->setAlreadyLoadedLibraries(['core/c']); $resolver->getLibrariesToLoad($assets) === ['core/a', 'core/b', 'core/d'] Parameters \Drupal\Core\Asset\AttachedAssetsInterface $assets: The assets attached to the

Resolves asset libraries into concrete CSS and JavaScript assets. Given an attached assets collection (to be loaded for the current response), the asset resolver can resolve those asset libraries into a list of concrete CSS and JavaScript assets. In other words: this allows developers to translate Drupal's asset abstraction (asset libraries) into concrete assets.
