This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
The pushManager
property of the ServiceWorkerRegistration
interface returns a reference to the PushManager
interface for managing push subscriptions; this includes support for subscribing, getting an active subscription, and accessing push permission status.
Syntax
myPushManager = ServiceWorker.pushManager
Value
A PushManager
object.
Examples
this.onpush = function(event) { console.log(event.data); // From here we can write the data to IndexedDB, send it to any open // windows, display a notification, etc. } navigator.serviceWorker.register('serviceworker.js').then( function(serviceWorkerRegistration) { serviceWorkerRegistration.pushManager.subscribe().then( function(pushSubscription) { console.log(pushSubscription.subscriptionId); console.log(pushSubscription.endpoint); // The push subscription details needed by the application // server are now available, and can be sent to it using, // for example, an XMLHttpRequest. }, function(error) { // During development it often helps to log errors to the // console. In a production environment it might make sense to // also report information about errors back to the // application server. console.log(error); } ); });
