TypeError: firebase.messaging is not a function in node.js

While trying to fetch the FCM messages in node.js using firebase module, following error "TypeError: firebase.messaging is not a function" is occurring. 

var firebase = require("firebase");

firebase.initializeApp({
    apiKey: "xxxxxxx",
    authDomain: "xxxxxxx",
    databaseURL: "xxxxxxx",
    projectId: "xxxxxxx",
    storageBucket: "xxxxxxx",
    messagingSenderId: "xxxxxxx"
});

const messaging = firebase.messaging();

How to rectify this error and how to use firebase module to pull messages??

In my case was that I was importing firebase only as 

import '@firebase/app'

instead of 

import * as firebase from '@firebase/app'

after formatting it, I was able to access messaging from firebase.firebase.messaging()

For react-native-firebase version 5.x.x and 6.x.x

import firebase from '@react-native-firebase/app'
import '@react-native-firebase/messaging'

for example get token

const fcmToken = await firebase.messaging().getToken();
console.log(fcmToken)

You must included import '@firebase/messaging' for it to work. So it's supposed to look like this:

import * as firebase from 'firebase/app';
import '@firebase/messaging';

The documentation for Firebase does not make it clear that there is a difference of features available based on the current environment. firebase.messaging is not available to a Node.js client, but is available from the firebase-admin package. However, this package alone comes with a different set of features specfically for firebase.messaging.

You can see what's available to you based on your environment in the Firebase Reference docs. Specifically for your case the Node.js (Client) section.

The criteria you are trying to use only works on the browser:

You have to require firebase-messaging, check this full sample it will guide you https://github.com/firebase/quickstart-js/tree/master/messaging

For nodeJS implementation, you have to use admin.messaging

https://firebase.google.com/docs/reference/admin/node/admin.messaging

// Get the Messaging service for the default app
var defaultMessaging = admin.messaging();
