download-counts

Average daily download counts for every npm package.

This package:

• collects download counts from npm's download-counts web service.
• collects one year's worth of download data for each package.
• is a key-value object. Keys are package names, values are average daily downloads.
• works offline. It's just a big JSON object.
• weighs about 12 MB.
• includes scoped package names
• is regularly updated using a Heroku bot. See script/release.sh and zeke.sikelianos.com/npm-and-github-automation-with-heroku/ for info on how that works.
