Notifications API

The Notifications API allows web pages to control the display of system notifications to the end user. These are outside the top-level browsing context viewport, so therefore can be displayed even when the user has switched tabs or moved to a different app. The API is designed to be compatible with existing notification systems, across different platforms.

Concepts and usage

On supported platforms, showing a system notification generally involves two things. First, the user needs to grant the current origin permission to display system notifications, which is generally done when the app or site initialises, using the Notification.requestPermission() method. This will spawn a request dialog, along the following lines:

From here the user can choose to allow notifications from this origin, block notifications from this origin, or not choose at this point. Once a choice has been made, the setting will generally persist for the current session.

Note: As of Firefox 44, the permissions for Notifications and Push have been merged. If permission is granted for notifications, push will also be enabled.

Next, a new notification is created using the Notification() constructor. This must be passed a title argument, and can optionally be passed an options object to specify options, such as text direction, body text, icon to display, notification sound to play, and more.

Note: This feature is available in Web Workers.

In addition, the Notifications API spec specifies a number of additions to the ServiceWorker API, to allow service workers to fire notifications.

Note: To find out more about using notifications in your own app, read Using the Notifications API.

Notifications interfaces

Notification: Defines a notification object.

Service worker additions

ServiceWorkerRegistration: Includes the ServiceWorkerRegistration.showNotification() and ServiceWorkerRegistration.getNotifications() method, for controlling the display of notifications.
ServiceWorkerGlobalScope: Includes the ServiceWorkerGlobalScope.onnotificationclick handler, for firing custom functions when a notification is clicked.
NotificationEvent: A specific type of event object, based on ExtendableEvent, which represents a notification that has fired.

Basic support	22 22 Before Chrome 22, the support for notification followed an old prefixed version of the specification and used the `navigator.webkitNotifications` object to instantiate a new notification. Before Chrome 32, `Notification.permission` was not supported. Before Chrome 42, service worker additions were not supported. Starting in Chrome 49, notifications do not work in incognito mode. 5 Prefixed Prefixed Requires the vendor prefix: -webkit-	Yes	22 22 4 Prefixed Prefixed Requires the vendor prefix: -moz-	No	25	6
