I just run a simple npm install morgan in a folder and for some reason it adds all the sub dependencies to the parent folder. See image attached
Yes, this is a new feature in npm 3.x, you can read about it here:
https://github.com/npm/npm/releases/tag/v3.0.0
Your dependencies will now be installed maximally flat. Insofar as is possible, all of your dependencies, and their dependencies, and THEIR dependencies will be installed in your project's
node_modulesfolder with no nesting. You'll only see modules nested underneath one another when two (or more) modules have conflicting dependencies.
Basically, it now handles dependencies with as little nesting as possible.
