Quick example

Set some feature in your config (or use your own activator for fetching features from wherever you want) ...

flagception:

    # Your Features (optional you left it empty)
    features:
    
        # Feature name as key
        feature_123:
            # Default flag if inactive or active (default: false)
            default: true
            
        # Feature state from an environment variable
        feature_abc:
            env: FEATURE_ENV_ABC
            
        # Feature with constraint (active if user id is 12 OR it is between 8 am and 6 pm)
        feature_def:
            constraint: 'user_id == 12 or (date("H") > 8 and date("H") < 18)'
                    
        # All togther (chain)
        feature_def:
            default: false
            env: FEATURE_ENV_ABC
            constraint: 'user_id == 12 or (date("H") > 8 and date("H") < 18)'

... and use it in controller, services or twig:

{% if feature('feature_123') %}
    {# Execute if feature is active ... #}
{% endif %}

See usage documentation for detailed examples.

Profiler
