This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The permissionState() method of the PushManager interface returns a Promise that resolves to a DOMString indicating the permission state of the push manager. Possible values are 'prompt', 'denied', or 'granted'.
Note: As of Firefox 44, the permissions for Notifications and Push have been merged. If permission is granted for notifications, push will also be enabled.
Syntax
PushManager.permissionState(options).then(function(PushMessagingState) { ... });
Parameters
options Optional- An object containing optional configuration parameters. It can have the following properties:
userVisibleOnly: A boolean indicating that the returned push subscription will only be used for messages whose effect is made visible to the user.applicationServerKey: A public key your push server will use to send messages to client apps via a push server. This value is part of a signing key pair generated by your application server and usable with elliptic curve digital signature (ECDSA) over the P-256 curve.
Returns
A Promise that resolves to a DOMString with a value of 'prompt', 'denied', or 'granted'.
