This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
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()); });
