cm_data_layer

This module provides a messenger-like service for pushing events/data into the client side data layer.

Usage

The intended use of this module is through the cm_data_layer.data_layer service eg.

\Drupal::service('cm_data_layer.data_layer')->push([
  'event' => 'myEvent',
  'data' => [
    'some_key' => 'some_value',
  ],
]);

Or more realistically, you'll oftentimes be in an event subscriber where the service can be an injected dependecy:

$this->dataLayer->push([
  'event' => 'myEvent',
  'data' => [
    'some_key' => 'some_value',
  ],
]);
