How to send Firebase Cloud Messaging from a node server?

Question

Is there any way to send notifications from FCM from a node.js server?

I haven't found anything about it inside documentation.

Answer 1

Sending messages through Firebase Cloud Messaging takes calling an HTTP end point as described in the documentation on sending downstream messages.

Something as simple as this could do the trick:

var request = require('request');  function sendMessageToUser(deviceId, message) {   request({     url: 'https://fcm.googleapis.com/fcm/send',     method: 'POST',     headers: {       'Content-Type' :' application/json',       'Authorization': 'key=AI...8o'     },     body: JSON.stringify(       { "data": {         "message": message       },         "to" : deviceId       }     )   }, function(error, response, body) {     if (error) {        console.error(error, response, body);      }     else if (response.statusCode >= 400) {        console.error('HTTP Error: '+response.statusCode+' - '+response.statusMessage+'\n'+body);      }     else {       console.log('Done!')     }   });  sendMessageToUser(   "d7x...KJQ",   { message: 'Hello puf'} ); 

Update (April 2017): you can now also run code very similar to this in Cloud Functions for Firebase. See https://firebase.google.com/docs/functions/use-cases#notify_users_when_something_interesting_happens

//I done by this code using node- gcm module. //We're using the express framework and the node-gcm wrapper  var express = require('express'); var gcm = require('node-gcm'); //init express var app = express(); app.get('/push', function (req, res) {     var message = new gcm.Message({         data: { key1: 'hello' },         notification: {             title: 'SPECOZ Offers1',             body: 'body_data'         }     });      // Set up the sender with you API key, prepare your recipients' registration tokens.     var sender = new gcm.Sender('Api_Key');     sender.send(message, 'device_token', function (err, response) {         if (err) {             console.error("Error:", err);           }          else console.log("Response:", response);         res.send(response);     });  }); app.listen("pass the port number");

const admin = require('firebase-admin');
  const payload = { 
   notification: {
        title: 'this is title', body: 'this is body'
    },
   data: {
           balance: 100,
          priceplanId: 1235 
  }
}  
const deviceToken ='yourtoekn' | ['yourtoekn'];
admin.messaging().sendToDevice(deviceToken, newpayload)
                .then((_response) => console.log(_response))
                .catch(error => console.log(error));
