Installing an npm package and meteor build system

I’m not familiar with the details of npm and meteor build system.

I have some code which I use between two meteor apps, if I install that code into my project and a npm module from github, will meteor build that code for me on deployment, or should I somehow build the code before installing the module into my meteor projects?

Not sure where to start, any resources would be appreciated.
Thanks.

You’ll wanna read through Meteor’s History.md for version 1.7
