I am a MeteorJS developer and I use MeteorKitchen a lot. It helps get an MVP up and going in no time!
There is just one problem, with fairly large apps the the JSON constructor file becomes huge and unmanagable (especially since you cannot comment JSON code).
I desired to break my JSON into modules and let the computer handle merging them. The attached script deep merges my JSON and allows me to specify the order to merge my JSON files. Perfect.
Modify as needed then from the terminal run $ node mergeJSON.js
