I've used the Google Cloud Messaging but it seems to be deprecated. Is it still working? In the other hand, Is possible to use Firebase Cloud Messaging with Phonegap?
Yes, you can use GCM via the GitHub - phonegap/phonegap-plugin-push: Register and receive push notifications plugin. We are working on FCM support in the 2.0.0 branch. So if you adopt this plugin your API will remain the same once FCM support is ready.
