Check the Browser compatibility table carefully before using this in production.

read-only property of the PushEvent
interface returns a reference to a PushMessageData
object containing data sent to the PushSubscription
.
Syntax
var myPushData = PushEvent.data;
Value
A PushMessageData
object.
Examples
The following example takes data from a PushEvent and displays it on all of the service workers' clients.
self.addEventListener('push', function(event) { if (!(self.Notification && self.Notification.permission === 'granted')) { return; } var data = {}; if (event.data) { data = event.data.json(); } var title = data.title || "Something Has Happened"; var message = data.message || "Here's something you might want to check out."; var icon = "images/new-notification.png"; var notification = new Notification(title, { body: message, tag: 'simple-push-demo-notification', icon: icon }); notification.addEventListener('click', function() { if (clients.openWindow) { clients.openWindow('https://example.blog.com/2015/03/04/something-new.html'); } }); });
