The web is getting pushy
summary
Demo builds a Twitter-hashtag app that uses Service Worker plus EventSource on the client, a Node backend and the Fetch API to register a PushManager subscription and send the endpoint to the server, then triggers notifications with registration.showNotification. Push works in Chrome (service worker since 40, push since 42) and Firefox 44; Safari uses a nonstandard APNS flow, Edge/Safari are still on roadmaps. Live demo hits permission glitches but ultimately shows notifications while the page is closed and reopens the page on click.
