Unable to reference other JS code after migrating Parse

Question

After migrating from Parse.com to Parse Server on Heroku, I am unable to run cloud-code like this:

 var foo = require('cloud/test.js')

Before switching, this worked fine.

Answer 1

it turns out:

 require('./test.js') 

is the correct way to do this (due to server on heroku being linux based, as I was told)
