The getNotifications() method of the ServiceWorkerRegistration interface returns a list of the notifications that have been fired from the current service worker.


​ServiceWorkerRegistration.getNotifications(options).then(function(NotificationsList) { ... });


options Optional
An options object that can contain options to filter the notifications returned. The available options are:
  • tag: A DOMString representing a notification tag. If specified, only notifications that have this tag will be returned.

Return value

A Promise that resolves to a list of Notification objects.



var options = { tag : 'user_alerts' };

navigator.serviceWorker.ready.then(function(registration) {
  registration.getNotifications(options).then(function(notifications) {
    // do something with your notifications
