Create web app for mobile and pc

Hey all,
I would like to create a meteor project which will be over the web for PC and mobile platforms.
The HTML (templates) will be different ones, however the logic should be the same (JS files) .
I been searching for good practice which will fulfill my request, but i could not find one (with real separation of html CSS and JS).

Is it possible to create 2 meteor projects (one for web and other for mobile), with shared JS files (maybe third project)?

thanks for the help,

Here’s a guide to split your app into micro-services (@sashko’s favorite thing).
