PushManager: register() method

Deprecated: This feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Non-standard: This feature is not standardized. We do not recommend using non-standard features in production, as they have limited browser support, and may change or be removed. However, they can be a suitable alternative in specific cases where no standard option exists.

Note: This feature is available in Web Workers.

The register method is used to ask the system to request a new endpoint for notifications.

Note: This method has been superseded by PushManager.subscribe().

Syntax

register()

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 a string, which is the endpoint URL.

Note: If you do not need the URL any more, please use PushManager.unregister() to clean up after yourself.

Examples

const req = navigator.push.register();

req.onsuccess = (e) => {
  const endpoint = req.result;
  console.log(`New endpoint: ${endpoint}`);
};

req.onerror = (e) => {
  console.error(`Error getting a new endpoint: ${e.error}`);
};
