Any lib or how to receive upstream message on server?

Hi, when you send two or more requests by using fcm-node in a .js script there is an error that says that the app already exists.

In the node_modules/fcm-node there is a file called fcm.js

My solution is to edit this file, like this (I had already done this and it works):

else{ //accountkey object passed, new SDK 'de-promisefy' use <--- STAYS THE SAME
if(firebaseadmin.apps[0]){
firebaseadmin.apps[0].delete()
}
firebaseadmin.initializeApp({
credential: firebaseadmin.credential.cert(accountKey)
});
this.send = function(payload, _callback){ <--- STAYS THE SAME

Review all the implicitly declared variable scopes and adjust them to their proper scopes

A very bad library actually. lack of information and lack of guide to send messages to topics.
priority and content_available are not working and throw error.

Hi,

I'm facing following issue,

 var isSent =false

for(let token of tokens){ 
 isSent = await fcm.send(message, async (err, response)=> {
          if (err) {
                        console.log("Something has gone wrong!");
                        return false;
                    } else {
                        console.log("Successfully sent with response: ", response);
                        return true;
                    }
                });
}

Here isSent is always undefined , Is there is any synchronous call to send FCM messages ?

How do i get all registration_tokens?

fcm.send's callback is called twice.
please help!

fcm.send(message, function(err, response){
if(err) {
console.log("Something has gone wrong!")
} else {
console.log("Successfully sent with response: ", response) << called twice!
}
})

It successfully send push notification but then it crash in buffer.js as follows :

Successfully sent with response:  {"multicast_id":4628760918450252159,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1476179380585829%1243539d1243539d"}]}

I tried it on Mac OSX El Capitan if that helps.
Thanks

this is not really an issue because the library is excellent... anyway i'm wondering if there is a fast way to force the screen on (when the device is locked) with a notification.
Is there any parameter or setting that we can use to do this? Thank you

After updating to 1.5 I get this error.

I'm using this method:

const FCM = require('fcm-node');
const serverKey = require('../private/firebase-adminsdk.json');
const fcm = new FCM(serverKey);

Any Idea what could cause this?

Getting below error on ubuntu
SyntaxError: Block-scoped declarations (let, const, function, class) not yet supported outside strict mode
Fixed it by adding "use strict"; on line 6.

I have added changes as you had suggested.
Even after adding the FCM key and the device token. I'm getting this error and failure to send the notification.

Please help me out. Thank you!

Recently got an error response “TOPICS_MESSAGE_RATE_EXCEEDED” which I never got in the past.
It happened from 2016/8/25 until now.
My node server is simply sending 10 messages to my client with “topics/global” in loop.
It has been running well since year ago. But recently it became sending error but only succeed for 2 messages in 10 messages.

I am using a cordova based hybrid mobile app. My app is built using [email protected]. I need to integrate fcm push-notifications to my app, I'm using [email protected].

I added the package into my package.json.
By doing yarn add fcm-node.
Then I imported it in my controller file, by writing code like =>
import FCM from 'fcm-node';, /
import * as FCM from 'fcm-node';/
also tried var FCM = require('fcm-node');

When I install the app or try to run it on browser, i get an error:

    Error: Could not find module `fcm-node` imported from `stock/controllers/notifications`
    at missingModule (vendor.js:252)
    at findModule (vendor.js:263)

And even in my vs-code its highlighted with error

Same issue with the require statement too.

I even tried installing by npm install @types/fcm-node. But still no luck.

Could you please help me resolve this ?

Hey,

I have the following behaviour: iOS-Users receive messages send through the firebase-console BUT not send via the script. Android-Users receive both.

I tried it with single-device-targeting, topic-targeting and with/without priorities.

Is there anything else to be aware of? Are pushes send from the HTTP-API using the dev-cert instead of the prod-cert?

I really would appreciate a working example.. Here is my test-script:

var process = require('process');
var winston = require('winston');

process.title = 'fanradio.streamstatus';

var firebase = require('firebase');

winston.info('Logging in...');

firebase.initializeApp({
  serviceAccount: './service.json',
  databaseURL: 'MYURL',
});

winston.info('Authenticated via Firebase.');

var FCM = require('fcm-node');
var fcm = new FCM('MYKEY');

var topic = 'MYSINGLEDEVICETARGET';
// topic = '/topics/test';
var push = { text: 'foo' };

fcm.send({
  to: topic,
  notification: { priority: 'high', body: push.text },
}, function (error, response) {
  if (error) {
    winston.warn('A pushmessage could not be send', { error });
    return;
  }

  winston.info('Push was send', response);
});

I want to send a push notification in an encrypted format. Is there any way of doing it?

Some iOS users report a delay receiving the notifications and even a 'not receive at all' scenario if the priority field is not set. This is due to a delivery policy with APN (See APNs Provider API for a more detailed info: https://developer.apple.com/library/content/documentation/NetworkingInternet/Conceptual/RemoteNotificationsPG/Chapters/APNsProviderAPI.html#//apple_ref/doc/uid/TP40008194-CH101-SW2)

^The link on the ReadMe is dead and also, I don't think that is true anymore.

Hello,
Would you please upgrade your package.json to use newer version of firebase-admin, now npm shouts:

Step #1: npm WARN deprecated [email protected]: This version is no longer maintained. Please upgrade to the latest version.

Hello.

I develop FCM to send 3 apps using this library.
but showing follow error messages.
How to set this case?

• code
  const serverKey_10001 = require('../config/pushkey/b.json');
  const serverKey_10002 = require('../config/pushkey/a.json');
  const fcm_zeroshop = new FCM(serverKey_10001, undefined, 'zeroshop');
  const fcm_hidoc = new FCM(serverKey_10002, undefined, 'hidoc');

fcm_zeroshop.send(message, (err, response) => {
});

-error message
The default Firebase app does not exist. Make sure you call initializeApp() before using any of the Firebase services.

Successfully sent with response: {"multicast_id":5979505685602066267,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1479724040861830%0000000000000000"}]}
I put my own server key and message token
and client app is implemented with FirebaseMessagingService and FirebaseInstanceIDService.
When I run the server, it returns success response like above message. However, client app doesn't get any notification. what am I missed?

var message = { //this may vary according to the message type (single recipient, multicast, topic, et cetera)
    to: 'registration_token', 
    collapse_key: 'your_collapse_key',

    notification: {
        title: 'Title of your push notification', 
        body: 'Body of your push notification' 
    },

    data: {  //you can send only notification or only data(or include both)
        my_key: 'my value',
        my_another_key: 'my another value'
    }
};

I am ok to create a working example code though, I am not finding what should I put on the above mentioned field for registration token, collapse key and the data keys.

Support for Typescript, Please
Thanks

Hi there, I've been using fcm-node in my nodejs app for a while now and it's been great. But there are some cases where I have my doubts on how to proceed:
I have some cases where I need to send a certain type of notification with user-specific payloads but with the same push notification message. The approach I've been using nowadays is, IMHO inefficient and I'd like to share it with you and ask if there is a way of doing this in a better way.

I'm currently creating separate notifications and sending each one with the same message, but different payloads (aka ids of one of my classes, so that the client knows how to react to the notifications when they open it). So if I have lotsof this messages, my server ends up iterating them all, which I find mostly inefficient.

I work as well with mandril-api and they have a great approach to send bulk emails with the same template, but different payloads and that's what I've been searching to do with fcm-node, to no success. Can someone help me with the reason why there is no such feature, or if there is, which feature I can use to send bulk notifications with the same message, but different data payloads?

Thanks in advance!

I don't know whether is me wrote the code wrote or something, it just can't fire up the callback function?

Since last two days, InvalidServerResponse error gets displayed every single time.
No code changes and this thing was working before.

How to use rich text notification, i want to send image that display event if app is in background.

so i want to add "mutable_content": true,

my current code is as below.

var message = { //this may vary according to the message type (single recipient, multicast, topic, et cetera)
                                            to: existToken.device_token, 
                                        // collapse_key: 'your_collapse_key',
                                            
                                            notification: {
                                                title: 'title',

                                            }
                                        };
                                        
                                        fcm.send(message, function(err, response){
                                            if (err) {
                                                console.log("Something has gone wrong!");
                                            } else {
                                                console.log("Successfully sent with response: ", response);
                                            }
                                        });

I saw that Firebase released this:

A new admin.messaging() service allows you to send messages through Firebase Cloud Messaging. The new service includes the sendToDevice(), sendToDeviceGroup(), sendToTopic(), and sendToCondition() methods.

https://firebase.google.com/support/release-notes/admin/node
https://firebase.google.com/docs/reference/admin/node/admin.messaging

Maybe we should use it?

As per the warning on Readme, it is advisable to use firebase-admin instead of fcm-node. I followed the link to documentation but am not sure how to implement it.

It would be better to have a wiki conveying how to migrate from fcm-node to firebase-admin. Something like what exactly I need to change if I have implemented fcm-node and want to replace it with firebase-admin.

Any help would be appreciated. Thanks.

can you provide sample code to send message with image?

Hi,
I've tried adding options to the message payload, but I always get an error like this:

{ code: 'messaging/invalid-payload',
message:
'Messaging payload contains an invalid "options" property. Valid properties are "data" and "notification".' },
codePrefix: 'messaging'
}

Please let me know if there is a way to set priority

fcm.send(message, function(err, response) { if (err) { let errorData = JSON.parse(err); let statusData = { 'success' : errorData.success, 'failure' : errorData.failure } updateStatus(pushId, statusData.success, statusData.failure); logger.error = 'Notification Not Sent To Few Users'; res.status(400).json(statusData); } else { let resData = JSON.parse(response); let statusData = { 'success' : resData.success, 'failure' : resData.failure } updateStatus(pushId, statusData.success, statusData.failure); logger.info(response); res.status(200).json(response); } });
Is there any way to find out the list of registration_id's for which the notification is failed!

Hey,

I'm having an issue where if I send two notifications in parallel, one to an ID of a device I know exists and one to a dummy ID, I get an 'InvalidRegistration' error from both .send() functions. The device does receive the 1st notification.

This causes an issue because when I get an error I want to remove that particular device token from the users tokens on the server. Currently it removes both the invalid token and the valid one resulting in the user having zero tokens and not receiving any future notifications.

Here's a gist of the script to cause this error:
https://gist.github.com/alexfoxy/1e8cdb7c3f127e6594e8e963e39224e6

You should get an output of:

FCM.send
FCM.send
{"multicast_id":8969037943863178607,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}
{"multicast_id":8969037943863178607,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}

If you send them in series it works correctly [ i.e. by moving send2() into the callback of send1() ] - output:

FCM.send
{"multicast_id":7502545296558413858,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1470046298701173%108c2029108c2029"}]}
FCM.send
{"multicast_id":8933073754773609814,"success":0,"failure":1,"canonical_ids":0,"results":[{"error":"InvalidRegistration"}]}

This might be a bug in Firebase itself so I'm also raising this as an issue with them.

I just pulled the latest code but found the runtime error below

ReferenceError: serverKey is not defined
at new FCM (/node_modules/fcm-node/lib/fcm.js:13:26)

It seems from the last checkin that uses the variable serverKey no longer exist

Hey there, I'd love to use this fork, but it looks like you changed the project from MIT to GPL when you forked it. Any particular reason you decided to do that? Any chance you could re-release it as MIT again?

Thanks!

my message is something like this
let message ={ to: user.fcmToken, notification: { title: "title message", body: body message, "sound": "default" } }

I'm new to push notifications. It seems like what I really want is collapse_key, where the user's notification tray combines or overwrites a notification. but, it only works when the receiving device is offline?

how do I get that functionality also when it's online? some documentation online mentions FCM supporting a tag key, but it's not apparent if I can use it with fcm-node

what are my options? thanks!

This is my payload.

{
        to: "",
        notification: {
          title:"Message Test",
          body:"Driver App"
        },
        data:{
          del_id: "121"
        },
        collapse_key:"Key 1",
      }

It work but if I add collapse_key I'm getting error

Messaging payload contains an invalid "collapse_key" property. Valid properties are "data" and "notification".

The following code always logs an error.

fcm.send(message, function(err, response){
if (err) {
console.log("Something has gone wrong!");
} else {
console.log("Successfully sent with response: ", response);
}
});

Printing err to console shows a JSON object of the format
{
"multicast_id": 78797070,
"success": 1,
"failure": 0,
"canonical_ids": 0,
"results": [
{
"message_id": "0:nsgjkndklg"
}
]
}

Suggestion:
fcm.send(message, function(jsonResponse){
var response = JSON.parse(jsonResponse);
if (response["failure"] > 0) {
console.log("Something has gone wrong!");
}
else {
console.log("Successfully sent");
}
});

I have installed my new app on my iPhone 5s using Xcode, and the FCM registration token is successfully given to me when I start the app.
When I use this token in the Firebase console (console.firebase.google.com), it works!
But when I send it with fcm-node, it doesn't :/
Note that my config is working for Android.
This is my test code:

const to = '<FCM registration token of my device goes here>'

const notification = {
  title: 'test 4',
  body: 'test 4',
}

const payload = {
  to,
  notification,
  priority: 'high',
  content_available: true, // tried without too
}

console.log('Sending to', to)

fcm.send(payload, (error, response) => {
  if (error) {
    console.error('Notification error:', error)
  } else {
    console.log('Notification sent:', response)
  }
})

And I get:

Sending to <token>
Notification sent: {"multicast_id":8677751413683945576,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1475855513649189%f587d512f587d512"}]}

But nothing arrives on the phone! (I have tried with the app in the background as well as killed)
Again, I do receive the ones sent through the Firebase console, so my setup is correct imo...

Hi,

on your documentation on NPM website you forget to add some properties inside the notifications

"notification": { "title": "notif title", "body": "notif body", **"sound": "default", "icon": "ic_icon", "priority": "high", "content_available": true** },

Hi. I have two mobile apps managed by a nodejs server which is responsible for sending notifications to both apps. Since each mobile app has it's own Firebase account, my nodejs server needs to keep two instances of FCM simultaneously.
Current behavior:
Version: "fcm-node": "1.4.1"
When I start the nodejs server I get the following message:

Error: The default Firebase app already exists. This means you called initializeApp() more than once without providing an app name as the second argument. In most cases you only need to call initializeApp() once. But if you do want to initialize multiple apps, pass a second argument to initializeApp() to give each app a unique name.
