README

Introducing the new open-source package for TYPO3, designed to streamline feature management through the use of feature flags. This package empowers developers and site administrators with a flexible and intuitive backend interface for creating and managing feature flags, enabling granular control over feature deployments. Whether you're rolling out new features incrementally, running A/B tests, or customizing user experiences, our package supports both standard and custom flags, offering a robust solution for feature toggling directly within TYPO3. Unlock seamless feature control and ensure your site's features are deployed smoothly and efficiently.

Features

• Custom Features via TYPO3 Backend
• Validate multiple Features at once
• Make your own feature class
• Fluid ViewHelper
• User and Group check for Features (Frontend & Backend)
• Compatible with TYPO3 7-13

composer require crazy252/typo3_features

Usage

You can use the original features core class from TYPO3. This class is extended by this package with a lot of new features.

use TYPO3\CMS\Core\Configuration\Features;

$features = GeneralUtility::makeInstance(Features::class);

$isFeatureEnabled = $features->isFeatureEnabled('dummy-feature');

// You can also check multiple features if you want
$isFeatureEnabled = $features->isFeatureEnabled('dummy-feature,other-feature');

Own feature class

You can also create your own logic for the feature check by adding the class namespace in the backend feature. After the feature is created in the backend, you can create a feature class with the interface from the package

namespace Vendor\Extension\Features;

class DummyFeature implements \Crazy252\Typo3Features\Contracts
{
    public function verdict(): bool
    {
        // Custom feature check
    }
}

Feature ViewHelper

This package gives also an viewhelper to check for features in the template. TYPO3 13.1 has an viewhelper for this. Before that, we backport the viewhelper to older versions.

<f:feature name="dummy-feature">
    This is being shown if the flag is enabled
</f:feature>

<f:feature name="dummy-feature,other-feature">
This is being shown if both flags are enabled
</f:feature>

Usage (TYPO3 9.0 or below)

You need to use the legecy class for features which can be replaced in higher versions easily with the feature core class.

use Crazy252\Typo3Features\Legacy\Features;

$features = GeneralUtility::makeInstance(Features::class);

$isFeatureEnabled = $features->isFeatureEnabled('dummy-feature');

$isFeatureEnabled = $features->isFeatureEnabled('dummy-feature,other-feature');
