Feature flags

Feature flags are configured in the .env or the local-dev/.ddev/docker-compose.environment.yaml file on ddev machine. To add a feature flag, use the following syntax:

# Feature flag for the specific tickets. Set them to true to activate the features.
- GSB11_FEATURE_1234_ENHANCED_PHP_PERFORMANCE=%const(bool:true)%

In this example, the feature flag GSB11_FEATURE_1234_ENHANCED_PHP_PERFORMANCE is set to true. To disable the feature, change the value to false or delete the setting.

Feature Flag Truth Table

This table illustrates the behavior of feature flags in various states.

Feature Flag State	Evaluated Value	Description
featureFlag = true	true	The feature is explicitly enabled.
featureFlag = false	false	The feature is explicitly disabled.
featureFlag = ''	false	An empty value is treated as false.
featureFlag not exist	false	A non-existent flag defaults to false.

Usage in PHP Code

To use a feature flag in your PHP code, you can check the flag's value in the global TYPO3 configuration. Here's an example:

if (GeneralUtility::makeInstance(Features::class)->isFeatureEnabled('GSB11_FEATURE_1234_ENHANCED_PHP_PERFORMANCE')) {
    // Only if the feature flag is set to true the feature is activated
    // Feature-specific code goes here
}

In this example, the feature-specific code will only execute if the feature flag GSB11_FEATURE_1234_ENHANCED_PHP_PERFORMANCE is set to true.

Usage in Fluid Templates

You can also use feature flags in your Fluid templates with a custom ViewHelper. First, ensure you include the namespace for the ViewHelper:

{namespace gsb=ITZBund\GsbCore\ViewHelpers}

Then, use the featureFlag ViewHelper to conditionally render content based on the feature flag:

<f:if condition="{gsb:featureFlag(featureKey: 'GSB11_FEATURE_1234_ENHANCED_PHP_PERFORMANCE')}">
    <!-- Feature-specific content goes here -->
</f:if>

Usage

Nothing to do.
