1. Advent: Your own EelHelper

December 3, 2017, 10:00 am

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!
