ServiceWorker class

Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers. The interface of the Service Worker API provides a reference to a service worker. Multiple browsing contexts (e.g. pages, workers, etc.) can be associated with the same service worker, each through a unique object. A object is available in the ServiceWorkerRegistration.active property, and the ServiceWorkerContainer.controller property — this is a service worker that has been activated and is controlling the page (the service worker has been successfully registered, and the controlled page has been reloaded.) The interface is dispatched a set of lifecycle events — install and activate — and functional events including fetch. A object has an associated ServiceWorker.state, related to its lifecycle.
