In Node.js the global object is called `global`, but you rarely need
to interact with it, and in most cases you shouldn't. If you need
something that is modularized make your own module, and include it
with the `require` function. And on initialization of that module you
may send it your from the main library.
module.js
module.exports = function (app) {
theFunkyThing = {};
// now i have access to the app.
return theFunkyThing;
};
app.js:
var app = {};
var module = require('module.js')(app);
