Nothing in what I'm doing prevents what you like about npm. In fact npm already abstracts away what you want in a little known command called `npm explore`.
Let's say you want to explore the dependency `foo` in your project. At the root of your project type `npm explore foo` and press enter and you'll be in a shell exploring the foo module. Then if you want to return, type `exit` and return and you'll be back in your project. Or if you want to go down the rabbit hole to a dependency of foo called bar, type `npm explore bar` and press enter.
`npm explore` is a great way to explore things and navigate to the dependencies used by the dependency you want to investigate. It basically uses the information in the current package.json to find the dependency you want.
