BeforePackageActivationEvent¶
The PSR-14 event \TYPO3\CMS\Core\Package\Event\BeforePackageActivationEvent
is triggered before a number of packages should become active.
Attention
This event is dispatched before an extension is activated in the Extension Manager, therefore starting with TYPO3 v11 this event is only dispatched in legacy installations, not in Composer-based installations. Use installer events by Composer for Composer-based installations.
