1. Advent: Your own EelHelper

On every Sunday in Advent I would like to show you a little tip for Neos.

Here’s the first tip on how to create your own EelHelper. It is very easy to create your own EelHelper and use it in fusion.¬† Just create a new class and implement the following interface:


An example EelHelper to get data from a repository looks like this:

namespace Package\Key\Eel\Helper;

use Neos\Flow\Annotations as Flow;
use Neos\Flow\Persistence\QueryResultInterface
use Neos\Eel\ProtectedContextAwareInterface;
use Package\Key\Domain\Repository\DataRepository;

 * DataHelper
class DataHelper implements ProtectedContextAwareInterface
     * @Flow\Inject
     * @var DataRepository
    protected $dataRepository;

     * Get all data
     * @return QueryResultInterface
    public function getAllData() {
        return $this->dataRepository->findAll();

     * All methods are considered safe, i.e. can be executed from within Eel
     * @param string $methodName
     * @return boolean
    public function allowsCallOfMethod($methodName) {
        return TRUE;

In order to use the EelHelper in Fusion, it must be defined in the Settings.yaml:

          'DataHelper': 'Package\Key\Eel\Helper\DataHelper'

The EelHelper can then be used in the fusion:

exampleEelValue = ${DataHelper.getData()}

I wish you a beautiful and peaceful Advent season!
