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 Classic mode installations, not in Composer-based installations. Use installer events by Composer for Composer-based installations.

Example

Note

Currently, we do not have an example for this event. If you can provide a useful one, please open an issue with your code snippets or a pull request.
