In part 1 of this 2 part series on making your module.exports reusable as standalone programs in JavaScript/CoffeeScript, I explained that this pattern allows for flexible reuse of a function like main:

var main = function(args) {
  console.log(args)
}

module.exports = main

if (module.parent === null) {
  main(process.argv)
}

In this article, I’ll show how to make a hubot script that wraps the dig command into a reusable standalone program. Assuming you’re using Linux, OSX, or another BSD and you have dig installed, let’s get started.

Likely we’ve all written something that is structurally like this when writing helper functions in JavaScript & CoffeeScript (I’ll be using JavaScript syntax in this article, but the principle is the same in CoffeeScript):

module.exports = function(args) {
  //something something here
}

And you’re all set to reuse your something something here anonymous functionalty elsewhere in your application’s codebase.
