In the Google Cloud Messaging for Chrome documentation there are no information about Topic Messaging feature. https://developers.google.com/cloud-messaging/chrome/client

Is not yet available?

Here is the GCM reference docs without subscribe method https://developer.chrome.com/apps/gcm

And here is the Android and iOS reference with the GcmPubSub class that provides subscribe/unsubscribe methods: https://developers.google.com/android/reference/com/google/android/gms/gcm/GcmPubSub https://developers.google.com/cloud-messaging/ios/api/gcm/interface_g_c_m_pub_sub

  • Hi, I found you from your post in Gcm's github issues, I'm running into unreliable topic messaging delivery to users, If you've managed to overcome your issue, can you take a look at this question here and answer it ? We'd greatly appreciate your time and help :) http://stackoverflow.com/questions/33146089/gcm-topic-messaging-doesnt-deliver-to-all-of-the-subscribers – SpiXel Oct 15 '15 at 10:53
  • @RockoDev There was a recently announced Firebase Cloud Messaging JavaScript library that may have what you were looking for. See my answer [here](http://stackoverflow.com/a/38091520/4625829). – AL. Oct 18 '16 at 04:11

Posting an answer for visibility to the answer I commented.

FCM recently announced (October 17, 2016) the Firebase JavaScript library:

Today we're announcing web support for Firebase Cloud Messaging (FCM) with the release of a JavaScript library. This extends our current browser support, enables a dramatically simpler implementation process, and brings powerful features such as Topics and Device Group Messaging to the web.

--

With the FCM JavaScript library, you can send web push notifications to single devices, topics or groups of devices. With the addition of topic support on the Web, we are making it possible for developers to send a message to their Android, iOS and Web users who have opted in to a particular topic. To take advantage of topics and device groups, you can use the server-side APIs to manage your topics and groups subscriptions.

Link to the Firebase documentation for Setting Up the JavaScript Client App.
