Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
Note: This feature is available in Web Workers.
The PushManager interface of the Push API provides a way to receive notifications from third-party servers as well as request URLs for push notifications.
This interface is accessed via the ServiceWorkerRegistration.pushManager property.
PushManager.supportedContentEncodings
Returns an array of supported content codings that can be used to encrypt the payload of a push message.
PushManager.getSubscription()
Retrieves an existing push subscription. It returns a Promise that resolves to a PushSubscription object containing details of an existing subscription. If no existing subscription exists, this resolves to a null value.
PushManager.permissionState()
Returns a Promise that resolves to the permission state of the current PushManager, which will be one of 'granted', 'denied', or 'prompt'.
PushManager.subscribe()
Subscribes to a push service. It returns a Promise that resolves to a PushSubscription object containing details of a push subscription. A new push subscription is created if the current service worker does not have an existing subscription.
PushManager.hasPermission() Deprecated Non-standard
Returns a Promise that resolves to the PushPermissionStatus of the requesting webapp, which will be one of granted, denied, or default. Replaced by PushManager.permissionState().
PushManager.register() Deprecated Non-standard
Subscribes to a push subscription. Replaced by PushManager.subscribe().
PushManager.registrations() Deprecated Non-standard
Retrieves existing push subscriptions. Replaced by PushManager.getSubscription().
PushManager.unregister() Deprecated Non-standard
Unregisters and deletes a specified subscription endpoint. In the updated API, a subscription is unregistered by calling the PushSubscription.unsubscribe() method.
this.onpush = (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((serviceWorkerRegistration) => {
serviceWorkerRegistration.pushManager.subscribe().then(
(pushSubscription) => {
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, the fetch() API.
},
(error) => {
console.error(error);
},
);
});
