ServiceWorkerRegistration: getNotifications() method

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 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 service workers on that same origin.

Syntax

js
getNotifications()
getNotifications(options)

Parameters

options Optional

An object containing options to filter the notifications returned. The available options are:

tag Optional

A string 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.

Examples

js
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
  });
});
