This is the code powering my chat room (chat.smarx.com). This code has been tested with node.js v0.5.7, including the native Windows executable and the iisnode IIS module.
To use it yourself, you'll need to provide a src/secrets.coffee file. Take a look at src/secrets.coffee.example.
Dependencies are specified in npm style via package.json. To install, use npm install or ryppi deps.
The application is written in coffeescript. To compile, run build.cmd.
Specify the port via the PORT environment variable (as with iisnode) or via the command line, like: node app.js -p 8000.
