Promise<void>

Example

Override to track analytics after adding to cart:

window.boostWidgetIntegration.extend('CartDrawerRecommendationController', (Base) => {
  return class extends Base {
    async afterCartDrawerAddToCart(productId, variantId) {
      await super.afterCartDrawerAddToCart(productId, variantId);
      // Fire custom analytics event
      window.dataLayer?.push({
        event: 'rcu_add_to_cart',
        product_id: productId,
        variant_id: variantId,
      });
    }
  };
});
