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
โmySubscription = 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 }) });
