@anabode/notification-firebase

External Notifier From System to Device

librabry can be used in an App Server implementation of Downstream notifications to devices. Notifications can be sent on the bases of DeviceToken or Topic.

Rest Interface is exposed for testability, however it should always be included as a library.

Prerequisites:

FCM account and service account credentials NB: GCM server admin keys are now deprecated

Usage:

npm i @anabode/notification-firebase --save

var payload = {
  "Message": "Will be disaplyed in body",
  "Title": "Header",
  "DeviceTopic": ""
};
var conf = {
  fcm: {
    app_name: "APP_NAME",
    scopes: ["https://www.googleapis.com/auth/firebase.messaging"],
    messagingEndpoint: "https://fcm.googleapis.com/v1/projects/"
  } 
};

/**
 *  cred - fcm credentials JSON object can be obtained from FCM dasboard for your project [example](https://console.firebase.google.com/u/1)
 */
var cred = {{
  "type": "service_account",
  "project_id": "APP_NAME",
  "private_key_id": "",
  "private_key": "",
  "client_id": "",
  "auth_uri": "",
  "token_uri": "",
  "auth_provider_x509_cert_url": "",
  "client_x509_cert_url": ""
};

var firebaseWorker = require('@anabode/notification-firebase');
// callers responsibility of this library to supply it with conf and cred objects
firebaseWorker.sendToTopic({body: payload}, conf, cred, (e, d) => {
    if (e) {
    console.error(e.message, e.stack);
  } else {
    console.log(d);
  }

var payload = {
  "Message": "Will be disaplyed in body",
  "Title": "Header",
  "DeviceToken": ""
};
var conf = {
  fcm: {
    app_name: "APP_NAME",
    scopes: ["https://www.googleapis.com/auth/firebase.messaging"],
    messagingEndpoint: "https://fcm.googleapis.com/v1/projects/"
  }
