PushSubscription.toJSON

This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The toJSON() method of the PushSubscription interface is a standard serializer: it returns a JSON representation of the subscription properties, providing a useful shortcut.

Syntax

mySubscription = subscription.toJSON()

Parameters

None.

Returns

A JSON object. It currently only contains the subscription endpoint, as an endpoint member.

Example

navigator.serviceWorker.ready.then(function(reg) {
  reg.pushManager.getSubscription().then(function(subscription) {
    var mySubscription = subscription.toJSON();
    // do something with subscription details
  })        
});
