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 endpoint
read-only property of the PushSubscription
interface returns a USVString
containing the endpoint associated with the push subscription.
The endpoint takes the form of a custom URL pointing to a push server, which can be used to send a push message to the particular service worker instance that subscribed to the push service. For this reason, it is a good idea to keep your endPoint a secret, so others do not hijack it and abuse the push functionality.
Syntax
var myEnd = pushSubscription.endpoint;
Value
A USVString
.
Example
navigator.serviceWorker.ready.then(function(reg) { reg.pushManager.subscribe({userVisibleOnly: true}).then(function(subscription) { console.log(subscription.endpoint); // At this point you would most likely send the subscription // endpoint to your server, save it, then use it to send a // push message at a later date }) })
