AddJavaScriptModulesEvent

JavaScript events in custom User Settings Configuration options should no longer be placed as inline JavaScript. Instead, use a dedicated JavaScript module to handle custom events.

Example

A listener using mentioned PSR-14 event could look like the following.

1. Register listener

   typo3conf/my-extension/Configuration/Services.yaml

   services:
      MyVendor\MyExtension\EventListener\CustomUserSettingsListener:
       tags:
         - name: event.listener
           identifier: 'myExtension/CustomUserSettingsListener'
           event: TYPO3\CMS\SetupEvent\AddJavaScriptModulesEvent
   

2. Implement Listener to load JavaScript module TYPO3/CMS/MyExtension/CustomUserSettingsModule

   namespace MyVendor\MyExtension\EventListener;
   
   use TYPO3\CMS\Setup\Event\AddJavaScriptModulesEvent;
   
   class CustomUserSettingsListener
   {
       // name of JavaScript module to be loaded
       private const MODULE_NAME = 'TYPO3/CMS/MyExtension/CustomUserSettingsModule';
   
       public function __invoke(AddJavaScriptModulesEvent $event): void
       {
           $javaScriptModuleName = 'TYPO3/CMS/MyExtension/CustomUserSettings';
           if (in_array(self::MODULE_NAME, $event->getModules(), true)) {
               return;
           }
           $event->addModule(self::MODULE_NAME);
       }
   }
