# Integration

## Events

Communication with the web components should be done via events. This ensures loose coupling and avoids issues if the implementation of the web component changes.

Examples:

* DO NOT
  * Call the method `Next` on a slot of an Announcement Bar
* DO
  * Publish the event `la:dn:announcement-bar:next`
