BootCompletedEvent
The PSR-14 event
\TYPO3\ is fired
on every request when TYPO3 has been fully booted, right after all configuration
files have been added.
This event complements the AfterTcaCompilationEvent which is executed after TCA configuration has been assembled.
Use cases for this event include running extension's code which needs to be executed at any time and needs TYPO3's full configuration including all loaded extensions.
Example
EXT:my_extension/Classes/Bootstrap/EventListener/MyEventListener.php
<?php
declare(strict_types=1);
namespace MyVendor\MyExtension\Bootstrap\EventListener;
use TYPO3\CMS\Core\Attribute\AsEventListener;
use TYPO3\CMS\Core\Core\Event\BootCompletedEvent;
#[AsEventListener(
identifier: 'my-extension/boot-completed',
)]
final readonly class MyEventListener
{
public function __invoke(BootCompletedEvent $e): void
{
// Do your magic
}
}
