How to write an NPM module that uses multiple files?

I have a simple local command-line module that I want to use in 2 different ways (basically different defaults), but it uses the same core logic, so I want to extract that logic into a third entity and use that from the two entry points.

I have everything working with two bin command scripts, but each file has its own copy of the logic to run, and I am not sure how to pull this duplicated code out into a third file within the same module. I figure I could do it by creating an entire separate module and loading it with require(), but I would rather just keep it together since it's tightly coupled.

The structure is like this:

bin\
  cmdone.js
  cmdtwo.js
core.js
package.json

I would like to move the logic, which currently exists in both cmdone.js and cmdtwo.js, into core.js and reference it from the two files in bin. Is this possible?

Well, after some more poking around, I discovered that this works:

const test = require('../core.js');

I suppose I misunderstood the distinction between Node modules and NPM packages. I was basically equating the two, but it seems that you can create and use modules entirely within packages, they don't have to be one-to-one.

If i understand your question correct, then what you need is require function of nodejs
