Feature Toggle Bundle for Symfony provides an easy way to manage feature flags in your Symfony applications.

Installation

   composer require michalzimka/feature-toggle

Configuration

You can create FeatureToggle entity with properties:

#[ORM\Column(length: 255, unique: true)]
private string $name;

#[ORM\Column(type: 'boolean')]
private bool $active;

Then create a repository implementing FeatureToggle\Repository\FeatureToggleRepositoryInterface and set this class in feature_toggle.yaml.

For example:

<?php

namespace App\Repository;

use Doctrine\ORM\EntityManagerInterface;
use FeatureToggle\FeatureToggle;
use FeatureToggle\Repository\FeatureToggleRepositoryInterface;
use App\Entity\FeatureToggle as FeatureToggleEntity;

class DatabaseFeatureToggleRepository implements FeatureToggleRepositoryInterface
{
    public function __construct(
        private EntityManagerInterface $entityManager,
    ) {}

    public function findByName(string $name): ?FeatureToggle
    {
        $entity = $this->entityManager
            ->getRepository(FeatureToggleEntity::class)
            ->findOneBy(['name' => $name]);

        if (!$entity) {
            return null;
        }

        return new FeatureToggle()
            ->setName($entity->getName())
            ->setActive($entity->isActive());
    }

    public function findAll(): array
    {
        $entities = $this->entityManager->getRepository(FeatureToggleEntity::class)->findAll();
        $toggles = [];

        foreach ($entities as $entity) {
            $toggles[] = new FeatureToggle()
                ->setName($entity->getName())
                ->setActive($entity->isActive());
        }

        return $toggles;
    }
}

Usage

use FeatureToggle\FeatureManager;

$featureManager = new FeatureManager($yourRepository);

if ($featureManager->isActive('new_awesome_feature')) {
    // Awesome feature is active
}

Command: toggle:list

The php bin/console toggle:list command allows you to manage and view the list of feature toggles in your application.
