How to send push notification to web browser

Question

I have been reading for past few hours about Push Notification API and Web Notification API  I also discovered that Google  amp  Apple gives push notification service for free via GCM and APNS respectively    I am trying to understand if we can implement push notification to browsers using Desktop Notification  which I believe is what Web Notification API does  I saw a google documentation on how this can be done for Chrome here  amp  here   Now what am still not able to understand is    Can we use GCM APNS to send push notification to all Web Browsers including Firefox  amp  Safari  If not via GCM can we have our own back-end to do the same    I believe all these answered in one answer can help a lot of people who are having similar confusions

May I redefine you question as below     Can we have our own back-end to send push notification to Chrome  Firefox  Opera  amp  Safari    Yes  By today  2017 05   you can use same client and server side implementation to handle Chrome  Firefox and Opera  no Safari   Because they have implemented web push notifications in a same way  That is Push API protocol by W3C  But Safari have their own old architecture  So we have to maintain Safari separately      Refer browser-push repo for guide lines to implement web push notification for your web-app with your own back-end  It explains with examples how you can add web push notification support for your web application without any third party services

You can push data from the server to the browser via Server Side Events  This is essentially a unidirectional stream that a client can  subscribe  to from a browser  From here  you could just create new Notification objects as SSEs stream into the browser   var source   new EventSource   events     source on  message   message   gt      var notification   new Notification message title        body  message body              A bit old  but this article by Eric Bidelman explains the basics of SSE and provides some server code examples as well

Javier covered Notifications and current limitations   My suggestion  window postMessage while we wait for the handicapped browser to catch up  else Worker postMessage   to still be operating with Web Workers    These can be the fallback option with dialog box message display handler  for when a Notification feature test fails or permission is denied   Notification has-feature and denied-permission check   if     Notification  in window      Notification permission      denied              use  window  Worker  postMessage   fallback

I assume you are talking about real push notifications that can be delivered even when the user is not surfing your website  otherwise check out WebSockets or legacy methods like long polling       Can we use GCM APNS to send push notification to all Web Browsers including Firefox  amp  Safari    GCM is only for Chrome and APNs is only for Safari  Each browser manufacturer offers its own service      If not via GCM can we have our own back-end to do the same    The Push API requires two backends  One is offered by the browser manufacturer and is responsible for delivering the notification to the device  The other one should be yours  or you can use a third party service like Pushpad  and is responsible for triggering the notification and contacting the browser manufacturer s service  i e  GCM  APNs  Mozilla push servers    Disclosure  I am the Pushpad founder
