Best way to implement push notifications with Firebase

Question

I am an iPhone app coder, and I\'m using Firebase as my backend server. Firebase doesn\'t support Push Notifications, so I\'ve been trying to figure out how to include them

Answer 1

Now Google rebranded GCM to Firebase Cloud Messaging and it now offers this cross platform service. Firebase also offers notifications.

These are the differences between these two services:

Firebase Cloud Messaging provides a complete set of messaging capabilities through its client SDKs and HTTP and XMPP server protocols. For deployments with more complex messaging requirements, FCM is the right choice.

Firebase Notifications is a lightweight, serverless messaging solution built on Firebase Cloud Messaging. With a user-friendly graphical console and reduced coding requirements, Firebase Notifications lets users easily send messages to reengage and retain users, foster app growth, and support marketing campaigns.

Answer 2

If you want device to device push messages and not just server to device, the only solution I found was OneSignal. I was able to add basic device to device push message support for my app in about an hour and it is currently free.

Both Batch and Firebase only support server to device push messages, not what you want for a chat app

Answer 3

Just realized that they've come out this:

Answer 4

Here's the answer I got from the Firebase team:

Firebase currently does not have push notification feature. You can use Firebase Queue and GCM to implement push notification in your app. Queues can be used in your Firebase app to organize workers or perform background work like generating thumbnails of images, filtering message contents and censoring data, or fanning data out to multiple locations in your Firebase database. Google Cloud Messaging (GCM) is a free service that enables developers to send messages between servers and client apps and it is available in both iOS and Android.

You can push an object with some data to the /queue/tasks location in your Firebase using any Firebase client or the REST API. Workers listening at that location will automatically pick up and process the job. From that, your workers can make a GCM push notification.

Here's my analysis:

It seems like there are a few solutions, but the two best ones are:

1) Use FirebaseQueue with Google Cloud Messaging.

2) Leverage the Push Notification functionality in Parse within the Firebase app.

I'm not sure which is better. Parse seems more proven, but Firebase Queue is more-easily integrated into the app (ie. it's nice have everything on Firebase and not having to set up a Parse app)

Anyways, I hope this thread helps out other people!

Answer 5

Firebase now has Notifications inbuilt. https://firebase.google.com/docs/notifications/

Answer 6

I had the same problem and managed to figure out a solution a while back. I have detailed my solution in the following posts https://stackoverflow.com/a/44192515/7048719 and https://stackoverflow.com/a/42240984/7048719

You have to create a firebase data service class and use a shared instance to hold the observers in memory when the app goes into background. From there it is just a matter doing what you wish.
