Clients: matchAll() method
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2018.
Note: This feature is only available in Service Workers.
The matchAll() method of the Clients
interface returns a Promise for a list of service worker
Client objects. 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

matchAll(options)
Parameters

An options object allowing you to set options for the matching operation. Available options are:
includeUncontrolled-
A boolean value — 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 isfalse. type-
Sets the type of clients you want matched. Available values are
"window","worker","sharedworker", and"all". The default is"window".
Return value
A Promise that resolves to an array of Client objects. In
Chrome 46/Firefox 54 and later, this method returns clients in most recently focused
order, correct as per spec.
Examples
clients.matchAll(options).then((clientList) => {
for (const client of clientList) {
if (client.url === "index.html") {
clients.openWindow(client);
// or do something else involving the matching client

}
});
