feat: dependsOn for service dependencies

[zehjotkah]

Summary

This PR adds a dependsOn feature to Klaro Cookie Consent Manager, allowing services to declare dependencies on other services. When a service is enabled, all its dependencies are automatically enabled. When a dependency is disabled, all dependent services are automatically disabled.

Changes

Core Implementation

File: src/consent-manager.js

1. Forward Dependencies (Lines 134-144): When enabling a service, automatically enable all services it depends on
2. Reverse Dependencies (Lines 145-154): When disabling a service, automatically disable all services that depend on it
3. Accept All Support (Lines 112-125): Ensure dependencies are properly handled when accepting all services

Bug Fix

File: src/translations/hu.yml

• Fixed YAML syntax error on line 54 that was preventing the build from completing

Usage Example

var klaroConfig = {
    services: [
        {
            name: 'googleTagManager',
            title: 'Google Tag Manager',
            purposes: ['functional'],
            required: false,
        },
        {
            name: 'googleAnalytics',
            title: 'Google Analytics',
            purposes: ['statistical'],
            dependsOn: ['googleTagManager'],  // Declares dependency
            callback: function(consent, serviceConfig) {
                if (consent) {
                    window.dataLayer.push({'event': 'loadgtm-analytics'});
                }
            },
        }
    ]
};

Behavior

Forward Dependencies

• Enabling googleAnalytics automatically enables googleTagManager

Reverse Dependencies

• Disabling googleTagManager automatically disables googleAnalytics and any other services that depend on it

Multiple Dependencies

• The dependsOn property accepts either a string (single dependency) or an array of strings (multiple dependencies)

Testing

The feature has been tested with:

• Individual service toggles
• Accept all functionality
• Decline all functionality
• Multiple dependent services
• Both forward and reverse dependency scenarios

Backward Compatibility

This feature is fully backward compatible. Services without the dependsOn property continue to work exactly as before.

Files Changed

• src/consent-manager.js - Core implementation
