Can I use in Meteor.JS injection of my "clean Node.JS code"?

Can I use in Meteor.JS injection of my “clean Node.JS code”?.
How can i do it ? if it is possible.
I see basic functionality for use NPM modules “as is”.

For example: i need to create socket server that takes incomming UDP connections from outside service, parse and put info into DB. But user of meteor GUI can rule some of parameters of this server in reactive mode.
