TYPO3 extension typo3_dump_server
This extension brings the Symfony Var Dump Server to TYPO3.
This package provides a dump server that gathers all dump call outputs, preventing interference with HTTP or API responses.
🔥 Installation
Requirements
- TYPO3 >= 11.5
- PHP 8.1+
Composer
composer require --dev konradmichalik/typo3-dump-server
TER
Download the zip file from TYPO3 extension repository (TER).
📊 Usage
Console command
Start the dump server with the following command:
vendor/bin/typo3 server:dump
Use the format option to change the output format to html:
vendor/bin/typo3 server:dump --format=html > dump.html
Note
The dump server will be available at tcp://127.0.0.1:9912 by default. Use the environment variable TYPO3_DUMP_SERVER_HOST to change the host.
Dump
Use the dump function in your code:
dump($variable); // or \Symfony\Component\VarDumper::dump($variable);
ViewHelper
Use the symfony:dump ViewHelper in your Fluid templates:
<html xmlns:symfony="http://typo3.org/ns/KonradMichalik/Typo3DumpServer/ViewHelpers"> <symfony:dump>{variable}</symfony:dump>
Extension settings
By default, a dump() call will add something like the following output to the frontend if the dump server isn't running:
You can suppress this output with the suppressDump setting in the extension configuration. If this setting is enabled, the output will be suppressed and the dump will only be sent to the dump server.
You can find the extension settings in the TYPO3 backend under Admin Tools > Settings > Extension Configuration > typo3_dump_server.
Programmatic Handling
You can listen to dump events programmatically using TYPO3's PSR-14 event system:
use KonradMichalik\Typo3DumpServer\Event\DumpEvent; use TYPO3\CMS\Core\Attribute\AsEventListener; #[AsEventListener] final class MyDumpEventListener { public function __invoke(DumpEvent $event): void { $value = $event->getValue(); $type = $event->getType(); // Your custom logic here error_log("Dumped {$type}: " . print_r($value, true)); } }
Note
Register your event listener via the AsEventListener attribute (TYPO3 >= 13) or in your service configuration (see docs).
