AMD-compatible CommonJS Module/1.1 that can also be loaded in a script tag

another-way.js

// This boilerplate would allow a module to run in node.js or an 
// AMD-enabled browser environment. On node.js, the syntax is:
//     var Color = require("./Color").Color, 
//         color = new Color("#BADA55");
// In the browser, the syntax is:
//     var color = new Color("#BADA55"); // window.Color is implied

(function (define) {

define(function () {

    function Color(){}

    return Color;

});

}(
    // if define is not available, assume we're running in node.js
    this.define || (function (exports, moduleId) {
        return function (defFunc) {
          exports[moduleId] = defFunc();
        }
    })(this, 'Color')
));

According to this document, the exports free variable is also a property of the module free variable. So I added yet another way to do it. Note: I have not tested it. I just got this off of http://visionmedia.github.com/masteringnode/book.html

All of the above examples had some issue for me. Either I had to settle for the differing server/browser construction or I got ReferenceErrors (for exports) or something else.

However, I found https://github.com/kof/expose.js, included it at the top of my IIFE before my module definition and just added expose('ModuleName', ModuleDefinition); and everything works as I wanted.

I cannot verify that it is AMD compliant but as a developer who had a working "module" and wanted it to work the same way in the server and the browser, ideally without dictating any API design choices, this is ideal.

I've updated https://gist.github.com/969908 to include expose.js.
