PushManager.registrations()

Deprecated
This feature has been removed from the Web standards. Though some browsers may still support it, it is in the process of being dropped. Do not use it in old or new projects. Pages or Web apps using it may break at any time.

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

Syntax

var request = navigator.push.registrations();

Return

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.

PushRegistration

Those objects are anonymous JavaScript objects with the following properties:

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

Example

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);
    }
  }
}
