The unsubscribe() method of the CookieStoreManager interface stops the ServiceWorkerRegistration from receiving previously subscribed events.

subscriptions

An object containing:

name

A string with the name of a cookie.

url

A string with the url of the scope used to subscribe to this cookie.

A Promise that resolves with undefined when the service worker has been unsubscribed.

TypeError

Thrown if the URL passed in subscriptions does not match the service worker registration's scope.

In this example the ServiceWorkerRegistration represented by registration is unsubscribing from change events on the cookie named "cookie1" with a scope of "/path1".

const subscriptions = [{ name: "cookie1", url: `/path1` }];
await registration.cookies.unsubscribe(subscriptions);
