How to update the mongoose's version which has come along with this npm?

[AravindBoddu4]

I've been using this module to design my application's folder structure. Its working fine. But now it's giving errors when am using some other modules which are dependent on mongoose and mongodb. This module still has older versions of mongoose and mongodb as it wasn't updated in last 2 years. But I've to update the mongoose to the newest version as per my requirements. But I couldn't able to do that. I've got mongoose and mongodb modules as part of this module. How to update both mongo db and mongoose node modules?
