node.js - Clone database in Mongodb between hosts using node driver

Question

There are clone and copydb commands available in mongo shell, how to reach them in mongo node native driver(mongodb)?

That's what I have tried:

I discovered the db.command available in node native mongodb driver. Reading documentation I tried this piece of code (db is the destination db named 'newdb')

db = db.db('newdb');
db.addUser('newdbuser', 'newdbpass', {}, function (err) {
    err && console.log(err);
    console.log(authUrlForDb(config.MONGO_HOSTS));
    db.command({
        copydb: 1,
        fromhost: config.MONGO_HOSTS,
        fromdb: config.MOTHER_DB, // some database name
        todb: 'newdb',
        username: config.ADMIN_USERNAME,  //
        key: {
            username: config.ADMIN_USERNAME,
            password: config.ADMIN_PASSWORD
        }
    }, function (err, res) {
        console.log(config.MONGO_HOSTS);
        console.log(err, res);
        db.close();
    });
});

Which fails and logs this:

hostname1.host.io,hostname2.host.io
null { ok: 0, errmsg: 'access denied; use admin db' }

Answer 1

Have you tried using db.admin().command?
