PushManager: registrations() method

Available in workers

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

[!NOTE] This method has been superseded by the getSubscription() method.

Syntax

registrations()

Parameters

None.

Return value

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.

Examples

const req = navigator.push.registrations();

req.onsuccess = (e) => {
  if (req.result.length > 0) {
    req.result.forEach((result) => {
      console.log(
        `Existing registration ${result.pushEndpoint} ${result.version}`,
      );
    });
    // Reuse existing endpoints.
  } else {
    // Register for a new endpoint.
    const register = navigator.push.register();
    register.onsuccess = (e) => {
      console.log(`Registered new endpoint: ${register.result}`);
    };
  }
};
