gitinfo

Install:

npm install gitinfo

Get git information for your node.js app while it is running. Use like so:

var gitinfo = require(__dirname + '/../lib/index.js');

gitinfo.all(function(info){
  console.log(info); // Here is your info object, do as you please
});

Here's what your info object looks like:
