Sharing data between Browserify modules

gistfile1.js

// I have a Backbone model where I need to use the same API_URL variable
// on the server and client. With Sharify it looks something like this...

// app.js
sharify.data = { API_URL: 'http://artsy.net/api/v1' };
app.use(sharify);

// models/artwork.js
var Backbone = require('backbone'),
    API_URL = require('sharify').data.API_URL;

var Artwork = module.exports = Backbone.Model.extend({
  urlRoot: API_URL + '/artwork/'
};

// With express-state I can bootstrap that variable into a global on
// `window`, but to share that variable on the server I would need to
// expose it globally as well.

// app.js
expstate.extend(app);
app.expose({ API_URL: : 'http://artsy.net/api/v1' }, 'SHARED_DATA');
global.SHARED_DATA = app.locals.state; // This is what I wanted to avoid with Sharify

// models/artwork.js
var Backbone = require('backbone');

var Artwork = module.exports = Backbone.Model.extend({
  urlRoot: SHARED_DATA.API_URL + '/artwork/'
};

// That being said, maybe one global namespace in Node isn't that big of a deal.
