10 Manage Storefront Event Notification

The PubSub library allows you to manage your storefront notifications.

Commerce includes two mechanisms for storefront event notification:

• The PubSub library provides a way for code to publish and subscribe to a set of “global” messages. That is, any code in the application can publish messages about an event and any code can listen for those messages.
• The event-dispatcher module provides the ability to listen for events triggered by a specific instance of an object.
