How to work with NumberLong() with nodejs mongo driver

Question

I need to insert data into my mongoDB, like such:

db.collection('Test').insert({
     "Name" : "Some",
     "UserID" : NumberLong(2147483647),
      ...

Inserts should happen from a nodejs script that interacts with mongo db All is well, except for the NumberLong().

I'm getting the following error:

ReferenceError: NumberLong is not defined
    at /root/MongoPolluter/MongoPolluter.js:107:23
    at connectCallback (/root/MongoPolluter/node_modules/mongodb/lib/mongo_client.js:505:5)
    at /root/MongoPolluter/node_modules/mongodb/lib/mongo_client.js:443:13
    at _combinedTickCallback (internal/process/next_tick.js:73:7)
    at process._tickCallback (internal/process/next_tick.js:104:9)

What I have tried:

adding var BSON = require('bson'); after installing it. Maybe I should use BSONElements?
Read this: MongoDB differences between NumberLong and simple Integer? - from which I go the notion that I could use the NumberLong only from mongo shell? Not sure if that is correct.
Also read about this: var Long = require('mongodb').Long; - should I just replace NumbreLong() w/ Long.fromString('')? Is there no way of getting the NumberLong() to work?

Thanks

Long.fromString('') solution worked. But would be interesting to see ifs possible to use NumberLong() still. Same problem with ISOdate() (need to use new Date()). — Mindaugas Bernatavičius

NumberLong is using for mongo shell only. If you use in nodejs (javascript) it no mean. I use mongoose and only Number type of data

var mongoose = require('mongoose');
mongoose.connect('mongodb://localhost/test');

var MyNumber = mongoose.model('my_number', { long_number: Number });

var record = new MyNumber({ long_number: 1234556 });
record.save(function (err) {
  if (err) {
    console.log(err);
  } else {
    console.log('ok');
  }
});

// have to defind ObjectId when use even it a default type data of mongodb
var id = mongoose.Types.ObjectId('4edd40c86762e0fb12000003');
