Working with Git - I find myself switching branches quite often. With constant changes, I end up running versions on other branches and edit on the current.

current_branch.js

/*
Avoid all the confusion with this in your entry script
*/

var exec = require('child_process').exec;
var cmd = 'git branch | grep "*"'

exec(cmd, function(error, stdout, stderr) {
        console.log("server source : " + stdout);
});
