If you know their names,You can try the following example which requests the distance matrix data between Washington, DC and New York City, NY, in JSON format

var request = require('request');
request.get('https://maps.googleapis.com/maps/api/distancematrix/json?units=imperial&origins=Washington,DC&destinations=New+York+City,NY&key=YOUR_API_KEY'

, function (error, response) {
     if(error){
         //Error handling
     }else{
        /*
            the response will be in a "JSON" format, you can see it in 
            details by entering the previous URL into your web browser 
            (be sure to replace YOUR_API_KEY with your actual API key) 
        */
     }
  })

or you can use this module node-googlemaps which wrap the apis.

if you know their longitudes and latitudes, i think there are no npm packages include the needed google libraries needed for that so i suggest you to calculate the distance by Haversine formula by using this npm module Haversine formula and this is a simple example:

var haversine = require('haversine-distance')

var a = { latitude: 37.8136, longitude: 144.9631 }
var b = { latitude: 33.8650, longitude: 151.2094 }

// 714504.18 (in meters) 
console.log(haversine(a, b))
