This is an experimental technology
Because this technology's specification has not stabilized, check the compatibility table for usage in various browsers. Also note that the syntax and behavior of an experimental technology is subject to change in future versions of browsers as the specification changes.
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 }) });
