node-gcm | NodeJS wrapper library port to send data | Messaging library

Maybe have other solutions, but this is my solution.

• Use environment variable to switch connection strings - variable name: DB_CONNECTION_STRING

• Use Heroku platform-api to update Config Vars: Update DB_CONNECTION_STRING value.

The first, edit your code to select the db string dynamically:

The management of the display of notifications is done on the device. You have to make sure you are setting, on Android, a different NOTIFICATION_ID for each notification, or the last one will always replace the one before it.

the problem resolved, in fact I didn't find solution to send notification to all user, so I used Topics in android app like this: in my ionic app I add topics option to android options like:

I am facing the same problem with firebase. I am using Firebase together with Microsoft Azure Notification Hub. If I send a test message via Microsoft Notification Hub I only get one message and that message is handled by my Push Handler. Otherwise if I send push notifications through firebase console I am getting two message like you(also one is empty). One message is handled by my push service and the second one is somehow handled by "no code"! I cannot find in my code where the push notification send by firebase is handled? There must be a OnReceiveMessage method in the background which handles the notification. For me I come with following solution: I just uncommented my push handler and now I am only getting one notification, but this without sound...somehow I have to override that function and implement sound behaviour. Have you found a solution for that? The empty message is caused by your push handler the second full message is handled in the background by firebase.

I also getting two different types of message in my onReceive() method:

Microsoft: Bundle[{google.sent_time=1484748187461, from=230XXXXXXXXXX, google.message_id=0:1484748187469719%8a1048bff9fd7ecd, message=Test through Microsoft, collapse_key=do_not_collapse}]

Firebase: Bundle[{google.c.a.udt=0, google.sent_time=1484748603664, gcm.notification.e=1, google.c.a.c_id=3001008833206773803, google.c.a.ts=1484748604, gcm.n.e=1, from=230XXXXXXXXXXX, google.message_id=0:1484748603943016%8a1048bf8a1048bf, gcm.notification.body=Test through firebase, google.c.a.e=1, collapse_key=com.sub_zero.ipostcard}]

So the message received through firebase is handled one time in the background somewhere maybe in through the firebase lib and the second time I suppose by your handler. That why you getting two of them...Just uncomment your push handler and test it again.

/topics/ was missing from this line:

var myTopic="phoneNumber_"+number;

solution :

var myTopic="/topics/phoneNumber_"+number;
