This is a NodeJS interface for accessing the public Bit.ly API. The library was constructed by Nate Kirby, the author of the iOS Bit.ly app. Though not directly supported by Bit.ly, the library is endorsed for use on the Bit.ly developer site. The Bit.ly API allows developers to implement programmatic shortening, sharing, and tracking of links (URLs). Unique user-level and aggregate links can also be created to let users view real-time traffic and referrer data, as well as location and metadata.
