Clients.matchAll()

The matchAll() method of the Clients interface returns a Promise for a list of service worker clients. Include the options parameter to return all service worker clients whose origin is the same as the associated service worker's origin. If options are not included, the method returns only the service worker clients controlled by the service worker. 

Syntax

ServiceWorkerClients.matchAll(options).then(function(clients) {
  // do something with your clients list
});

Parameters

options Optional

An options object allowing you to set options for the matching operation. Available options are:

• includeUncontrolled: A Boolean — if set to true, the matching operation will return all service worker clients who share the same origin as the current service worker. Otherwise, it returns only the service worker clients controlled by the current service worker. The default is false.
• type: Sets the type of clients you want matched. Available values are window, worker, sharedworker, and all. The default is all.

Returns

A Promise that resolves to an array of Client objects. In Chrome 46 and later, this method returns clients in most recently used order.

Examples

clients.matchAll(options).then(function(clientList) {
  for(var i = 0 ; i < clients.length ; i++) {
    if(clientList[i].url === 'index.html') {
      clients.openWindow(clientList[i]);
      // or do something else involving the matching client
    }
  }
});
