Think of a simple TASK Management application which can have n number of users. Say User A can create a task & assign it to User B. I want to show a notification to User B.
I am using Firebase as BAAS and following code-snippet prints on console only when there is a task assigned to User B. To simplfy, Users collection in Firebase has a node called tasksAssignedToThisUser array and callback function will be watching tasksAssignedToThisUser location. Whenever a new task gets added to that array, callback function gets executed. Here is the code snippet:
var rootRef = firebase.database().ref();
rootRef.child('users').child(loggedInUserID).child('tasksAssignedToThisUser')
.on('child_added', function (newMessageSnapshot) {
console.log('Someone assigned a task to this user.');
console.log(newMessageSnapshot.val);
});
Everything works fine until here.
What I have understood by reading Firebase docs & other post's on SO about Push notifications or Firebase Cloud Messaging is:
Firebase Notifications lets users easily send messages to reengage and
retain users, foster app growth, and support marketing campaigns.
Before you can write client apps that use Firebase Cloud Messaging,
you must have an app server that meets the following criteria:
...
You'll need to decide which FCM connection server protocol(s) you want
to use to enable your app server to interact with FCM connection
servers. Note that if you want to use upstream messaging from your
client applications, you must use XMPP. For a more detailed discussion
of this, see Choosing an FCM Connection Server Protocol.
This is definitely not what I want and maintaining a server for sending push notifications makes sense when bulk messages needs to be pushed to large number of devices. So I didn't name my question as Real Time Push Notifications.
I see a function being executed, which meets my use-case and I just want app to display a notification to the user in his mobile system tray on that callback function execution.
I am using Ionic 1 for developing app, completely new to Firebase and Ionic too. If there is a simple serverless approach that Firebase itself provides which can suffice my requirement, then I would be more than happy to hear about it.

I have an AWS Postgres database, an API layer, and a React Native application. One user is trying to communicate with another (and this will be stored in the db) I want to let the intended user know that a message awaits them with a notification. I'm not using expo. I've looked at using OneSignal but the functionality seems limited in this aspect (unless I'm missing something) I've prefer to use React Native Local notifications. Does anybody know how to achieve this with either OneSignal or RNLC?
You want 2 users to communicate with each other, and via a notification to let them know they have a new message. You can send push notifications directly to a user by using the player id and our REST API. The player id will target only the user the notification was meant to be sent to.

I am currently building a messaging app using Firebase database. I was wondering if it is possible to send calendar event requests between two Firebase users.
So for example, the sender sends an event request to another user, and if the user accepts the request then that event is stored in both the sender and other users calendar.
Is this possible, possibly using eventkit?
Thanks
Yes, this is very possible, but completely up to you how you want to implement it.
I would first recommend a firebase function to tackle uploads (below) and then you can very easily send a notification to the other device using the same technique you would for a message.
You uploads could be done any number of ways. I think it is probably best to just mirror the behavior of a messaging app. For example, you have a node/document where you are savings the eventkit data. Upon writing to that node/document, your cloud function is triggered that notifies the receiving device.
I can provide more if necessary, but I would strongly suggest any tutorials about a firebase messaging/chat app but instead of writing a "message/text," you are writing your eventkit data.

Notifications
I am working on letting users know when another user e.g. liked their post, made a friend request etc.
I set up everything for cloud messaging with firebase and can send bulk messages at all my devices.
Now I want to introduce notifications which contain the current user, the user who did the action and what happened.
Unfortunately I did not find anything about this despite the general implementing of firebase cloud messaging.
My questions are:
1: Do i have to structure a database (e.g. .child("notifications").child(userId).... ?
2: How do I get the token from the stranger user I address with the notification?
3: How can I make the input variable?
I am happy about all kinds of help!
I am using Cloud Functions to handle events, I have some topics that trigger an event such as a write to my document store.
What I would like to do is on a change to my doc store, notify any users interested in that change that there is fresh data.
For example, a news feed. If User A triggers an activity that is written to the store, User B should receive an update that such an activity has taken place, either an instruction to poll new data or just the new event object.
I do not want to use the Firebase Realtime DB as it is a requirement to use MongoDB, however, I believe as Firebase can hook into the events on Google Cloud Functions, I should be able to trigger this still using events?
Is this correct? So far in Firebase I can only find triggers around Realtime DB..
I can sort of achieve this with FCM, however it feels like this is more aimed at giving the user notifications as it requires the user to accept them in the browser, where I want to notify the app itself, not the user.

Yes, but
Using only Firebase storage triggers is a bit tricky thing to do, as Firebase gives you a Single bucket to work on, so if there is a change in FirebaseStorage(FS) the event will be triggered regardless of in which folder the file is stored.

Yes, you can use FCM for it, but you will need to store FCM Token of every device in some kind of database(If you dont want to store in Firebase Database) to send it to users.
I want to notify the app itself, not the user.
You can pass payload in FCM through data instead of notification which will be received in onMessageReceived and then you can decide what you want to do with it.
i.e.
var payload = {
data: {
score: "850",
time: "2:45"
}
};
I'm making an app where I want to be able to set a basic notification (title, message, fire date) and have been trying to figure out the best way to setup the notifications. I'm working with Swift 3 and Firebase 3.
I don't want to use local notifications because if the user is logged in on multiple devices I want it to push to all those devices.
Is there a way to do this with FCM where a user can set a notification to fire at a specific date and time and have it fire on all (iOS) devices logged in?
If FCM doesn't have this, is there another APK that does? I've looked at Batch briefly but I'm already using Firebase.
Thanks in advance!
If your main use case is to send a push notification to a single user for his multiple devices, I suggest you make use of Device Group Messaging on iOS. As per the docs, it is typically used for:
With device group messaging, app servers can send a single message to multiple instances of an app running on devices belonging to a group. Typically, "group" refers a set of different devices that belong to a single user.
When it comes to sending the notification on a specific date, I'm pretty sure you can set it up in the Firebase Console.
However, if you intend it to be sent from the server, you have to implement it yourself, since I think, there is no currently API available or a parameter you can set in the payload that can be modified for the message to be sent for a specific date.
