RequireJS plugin to conditionally load modules based on environment

env.js

// Include { env: 'development' } in your RequireJS config
// When building (with r.js) set the value to 'production' or just omit it entirely
//
// Assuming the following directory structure:
//     - config/
//         - development.js
//         - production.js
//
// Load the appropriate file based on the current env:
//
//     var config = require('env!config');

define(function() {

    return {
        load: function(name, req, load, config) {
            if (!config.env || config.isBuild) {
                config.env = 'production';
            }

            var path = name + '/' + config.env;
            req([path], function(mod) {
                load(mod);
            });
        }
    };

});
