@deblasis Figured this could be done in parallel with the config refactoring. I didn't dive into the context so there's a chance it can be closed as a duplicate.

@Olshansk: This has been addressed already and I forgot to close it.

We discussed the concept of NodeModule in #235 (that I had introduced) but then in code-review we agreed it was unnecessary so I removed it.
