The registrations method is used to ask the system about existing push endpoint registrations.


var request = navigator.push.registrations();


A DOMRequest object to handle the success or failure of the method call.

If the method call is successful, the request's result will be an array of PushRegistration objects.


Those objects are anonymous JavaScript objects with the following properties:

A string representing the URL of the endpoint.
The current version that the push endpoint is at.


var req = navigator.push.registrations();

req.onsuccess = function(e) {
  if (req.result.length > 0) {
    for (var i = 0, l = req.result.length; i < l; i++) {
      console.log("Existing registration", req.result[i].pushEndpoint, req.result[i].version);
    // Reuse existing endpoints.
  } else {
    // Register for a new endpoint.
    var register = navigator.push.register();
    register.onsuccess = function(e) {
      console.log("Registered new endpoint", register.result);
