Peepcode-livestats is a project mainly written in JavaScript, it's free.
Results of my working through the excellent Peepcode node.js screencast.
After working through the excellent PeepCode node.js tutorial, I wanted to keep the results around, mainly since there were several changes I needed to make, compared to the version the tutorial created. Mostly small bugfixes and an update to use http.get instead of http.createClient.
