Notify allows you to access HTML5 Notification (and Vibrate) APIs from server side. To show notifications that will be visible also when browser window itself is not shown. Notice that these APIs are new, and not supported by all browsers yet. All Vaadin 8 supported browsers, except IE11, should work with this add-on. This add-on is replacement for Vibrate add-on that is available for Vaadin 7. NOTICE: On Chrome notifications only from from secure (read: HTTPS) sites.
