Defines a controller to serve Javascript aggregates.

Namespace

Drupal\system\Controller

Code

protected function getGroups(AttachedAssetsInterface $attached_assets, Request $request) : array {
  // The header and footer scripts are two distinct sets of asset groups. The
  // $group_key is not sufficient to find the group, we also need to locate it
  // within either the header or footer set.

    // file from each of the listed libraries. However, which scope an
    // individual library appears in is determined by the HTML page request as
    // well as the library definition, depending on the dependencies between
    // libraries. This means we must ignore the scope when collecting the
    // libraries and get them from both the header and footer in order.
    // When building the array, also remove the scope from each asset so that
    // it is ignored when calculating the hash, as in
    // JsCollectionOptimizerLazy::optimize().
