This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for the proper prefixes to use 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 spec changes.
The Clients interface of the Service Workers API represents a container for a list of Client objects.
Methods
Clients.matchAll()- Gets a list of service worker clients and returns them in a
Promise. Include theoptionsparameter to return all service worker clients whose origin is the same as the associated service worker's origin. Ifoptionsare not included, the method returns only the service worker clients controlled by the service worker. Clients.openWindow()- Opens a service worker
Clientin a new browser window. Clients.claim()- Allows an active Service Worker to set itself as the active worker for a client page when the worker and the page are in the same scope.
Examples
clients.matchAll(options).then(function(clients) {
for(i = 0 ; i < clients.length ; i++) {
if(clients[i] === 'index.html') {
clients.openWindow(clients[i]);
// or do something else involving the matching client
}
}
});
