ServiceWorkerGlobalScope.skipWaiting

The ServiceWorkerGlobalScope.skipWaiting() method of the ServiceWorkerGlobalScope forces the waiting service worker to become the active service worker.

This method can be used with Clients.claim() to ensure that updates to the underlying service worker take effect immediately for both the current client and all other active clients.

Syntax

ServiceWorkerGlobalScope.skipWaiting().then(function() {
  //Do something
});

Returns

A Promise.

Example

The following example causes a new version of a registered Service Worker to replace an existing one that is already installed, and replace the currently active worker on open pages.

self.addEventListener('install', function(event) {
  event.waitUntil(self.skipWaiting());
});
self.addEventListener('activate', function(event) {
  event.waitUntil(self.clients.claim());
});
