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??
