Hi @H3llsing,  
I have recently put some of the shared logic of two of my nodes into npm package [nr-msg-statistics](https://www.npmjs.com/package/nr-msg-statistics?activeTab=dependencies). It is added as a dependency e.g. in my [node-red-contrib-msg-speed](https://www.npmjs.com/package/node-red-contrib-msg-speed) as a dependency, where I create a subclass.  
Perhaps not the best way to do it, but it now saves me a lot of work...  
Bart
