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 getRegistrations() method of the ServiceWorkerContainer interface returns all ServiceWorkerRegistrations associated with a ServiceWorkerContainer in an array.  If the method can't return ServiceWorkerRegistrations, it returns a Promise


ServiceWorkerContainer.getRegistrations().then(function(ServiceWorkerRegistrations) { ... });



Return value

A Promise that resolves to an array of ServiceWorkerRegistration objects.


navigator.serviceWorker.getRegistrations().then(function(registrations) {
  document.querySelector('#status').textContent = 'ServiceWorkerRegistrations found.';
