BootCompletedEvent¶
New in version 11.4.
The PSR-14 event \TYPO3\CMS\Core\Core\Event\BootCompletedEvent 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¶
Registration of the event listener in the extension's Services.yaml:
EXT:my_extension/Configuration/Services.yaml¶
services:
# Place here the default dependency injection configuration
MyVendor\MyExtension\Bootstrap\EventListener\MyEventListener:
tags:
- name: event.listener
identifier: 'my-extension/boot-completed'
Read how to configure dependency injection in extensions.
An implementation of the event listener:
EXT:my_extension/Classes/Bootstrap/EventListener/MyEventListener.php¶
<?php
declare(strict_types=1);
namespace MyVendor\MyExtension\Bootstrap\EventListener;
use TYPO3\CMS\Core\Core\Event\BootCompletedEvent;
final class MyEventListener
{
public function __invoke(BootCompletedEvent $e): void
{
// Do your magic
}
}
