SourceRank is a methodology for assigning numerical scores to software libraries.

It was developed by the folks at libraries.io, an ambitious project that aims to track all the package managers.

For the full story on SourceRank, see docs.libraries.io/overview#sourcerank

This is a multi-package repository, also known as a monorepo

It houses two npm packages:

• sourceranks-data is a module that exports a LevelDB database that contains detailed SourceRank data for each package in the npm registry. It's on the big side, around 200MB.
• sourceranks is a smaller module (about 15MB) that contains just the SourceRank totals for each package. This is probably what you want.
