npm-library-description
Shows information about dependencies in your package.json

Installation
You can install via apm:
apm install npm-library-description
Or, just search for npm-library-description inside Atom's package panel.
What does it do?
Fetches the dependencies information from your package.json. Very useful to get the package's
information. Faster than looking for it in google.
How does it work?
Parses the file and looks whatever is inside dependencies and devDependencies.
After that it does an HTTP Request per dependency to fetch its information.
Usage
Just open a valid package.json and click in the information icon of a dependency.

Features
When it opens or updates an invalid file, it'll warn about bad parsing.

Additionally you can choose the option to just use mouse over to show the dependencies
