re-define
plugin for wrapping js files. It may be handy when you need to add some wrapper function around your code.
Usage:
var wrapFile = require('re-define-wrap')({
'./filepath.js': '!function() { }'
or './filepath.js': 'var a = 10; function init(startVal) { }; init(a);'
or './filepath.js': '(function (startVal) { })(10)'
})
