Slight typo with Chris  answer    Db authenticate user  password  function      callback        should be  Db authenticate user  password  function       callback        Also depending on your mongodb configuration  you may need to connect to admin and auth there first before going to a different database  This will be the case if you don t add a user to the database you re trying to access  Then you can auth via admin and then switch db and then read or write at will

I find using a Mongo url handy  I store the URL in an environment variable and use that to configure servers whilst the development version uses a default url with no password    The URL has the form   export MONGODB DATABASE URL mongodb   USERNAME PASSWORD DBHOST DBPORT DBNAME   Code to connect this way   var DATABASE URL   process env MONGODB DATABASE URL    mongodb DEFAULT URL   mongo connect DATABASE URL  mongodb server options         function err  db                if db  amp  amp   err              console log  connected to mongodb          lobby db                         else if err              console log  NOT connected to mongodb     err         lobby db
