How to add user in Mongo admin database from NodeJS?

Question

I want to add a super user to admin database from MongoDB using NodeJS. My first try is this:

var Db = require('mongodb').Db,
    MongoClient = require('mongodb').MongoClient,
    Server = require('mongodb').Server;

var db = new Db('admin', new Server('locahost', 27017));

// Establish connection to db
db.open(function(err, db) {
    if (err) { return console.log(err); }

    console.log("Opened database");

    // Add a user to the database
    db.addUser('superuser', '1234', {
        roles: [
            "userAdminAnyDatabase",
            "dbAdminAnyDatabase",
            "clusterAdmin",
            "readWriteAnyDatabase"
        ]   
    }, function(err, result) {
        if (err) { return console.log(err); }
        console.log("Added.");
    });
});

When running the script I got this error:

[Error: failed to connect to [locahost:27017]]

And before this:

How can I fix the script to add the user superuser with password 1234 to admin database from MongoDB?

Administrative operations like adding an admin should rather be done through the mongo shell, not through a program. — Philipp

@Philipp So, I guess the best alternative would be to run shell commands from Nodejs side... Right? — Ionică Bizău

When your error is [Error: failed to connect to [locahost:27017]] it likely means that the problem occurs long before you try to create a new user. So when you wonder how to create a user, you are searching in the wrong direction. — Philipp

new Server('locahost', 27017), Do you see any problem here? Look closely! Typo in localhost name — Sriharsha

Your mistake is in this line:

 var db = new Db('admin', new Server('locahost', 27017));

You made a typo. What you mean is localhost.
