The getNotifications() method of the ServiceWorkerRegistration interface returns a list of the notifications in the order that they were created from the current origin via the current service worker registration. Origins can have many active but differently-scoped service worker registrations. Notifications created by one service worker on the same origin will not be available to other active services workers on that same origin.
ServiceWorkerRegistration.getNotifications()
Syntax
serviceWorkerRegistration.getNotifications(options) .then(function(notificationsList) { /* ... */ });
Parameters

An object containing options to filter the notifications returned. The available options are:
-
tag: ADOMStringrepresenting 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.
Example
navigator.serviceWorker.register('sw.js'); var options = { tag : 'user_alerts' }; navigator.serviceWorker.ready.then(function(registration) { registration.getNotifications(options).then(function(notifications) { // do something with your notifications }) });
