Apart from dependencies and devDependencies, it would also be helpful if it listed out any CLI commands it adds via the 'bin' field, and a license explainer.
Also, a small bug: If there is no devDependencies, it says 'Package has no dependencies, try devDependencies'.
The license explainer is a very neat idea!
I think I'll link to tldrlegal[1] for that.
Bin and similar information, that can be extracted directly from the package.json without extra request will be provided at the top of the page soon.
Just updated the no dependency message with your suggestion!
