Grant user roles in MongoDB via nodejs

Question

I'm trying to write a code in Node.JS that grant roles to users in MongoDB. I know a way via the CLI:

db.grantRolesToUser( "<username>", [ <roles> ], { <writeConcern> } )

How can i do it through Node.JS?

Thanks

I don't know that it's the only way, but the only thing I can see in the docs is to grant a role when you add a user.

var MongoClient = require('mongodb').MongoClient,

test = require('assert'); MongoClient.connect('mongodb://localhost:27017/test', function(err, db) {

// Use the admin database for the operation
  var adminDb = db.admin();

  // Add the new user to the admin database
  adminDb.addUser('admin11', 'admin11', {roles : ['blah']}, function(err, result) {

    // Authenticate using the newly added user
    adminDb.authenticate('admin11', 'admin11', function(err, result) {
      test.ok(result);

      adminDb.removeUser('admin11', function(err, result) {
        test.ok(result);

        db.close();
      });
    });
  });
});
