I found this a difficult line to toe during development. Where do I encourage developers to do whatever they'd like, and where do I enforce some sort of standard? I tried to pick a middle ground. I avoid helper functions where I can. Want to do something before you save the model? Learn ES6 inheritance patterns and write a save() method around the Parent#save. Will still have to see where people run into the most trouble and go from there. But I would enjoy it if people could pick up Nodal and walk away confident they could build an ES6 app from scratch.
