ServiceWorkerRegistration: getNotifications() method

{{APIRef("Web Notifications")}}{{SecureContext_Header}} {{AvailableInWorkers}}

The getNotifications() method of the {{domxref("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 service workers on that same origin.

Syntax

getNotifications()
getNotifications(options)

Parameters

• options {{optional_inline}}
  • : An object containing options to filter the notifications returned. The available options are:
    • tag {{optional_inline}}
      • : A string representing a notification tag. If specified, only notifications that have this tag will be returned.

Return value

A {{jsxref("Promise")}} that resolves to a list of {{domxref("Notification")}} objects.

Examples

navigator.serviceWorker.register("sw.js");

const options = { tag: "user_alerts" };

navigator.serviceWorker.ready.then((registration) => {
  registration.getNotifications(options).then((notifications) => {
    // do something with your notifications
  });
});
