supporting both CommonJS and AMD

Question

Is there a way to create a javascript micro-library (a library that has no dependencies), that support all of the following module formats:

• Asynchronous Module Definition
• CommonJS
• exposing the library's exports as a global namespace object (no loader)

Answer 1

Yes, and I owe this answer to ded and his awesome modules:

(function(name, definition) {     if (typeof module != 'undefined') module.exports = definition();     else if (typeof define == 'function' && typeof define.amd == 'object') define(definition);     else this[name] = definition(); }('mod', function() {     //This is the code you would normally have inside define() or add to module.exports     return {         sayHi: function(name) {             console.log('Hi ' + name + '!');         }     }; })); 

This can then be used:

1. in AMD (e.g. with requireJS):

   requirejs(['mod'], function(mod) {     mod.sayHi('Marc'); }); 

2. in commonJS (e.g. nodeJS):

   var mod = require('./mod'); mod.sayHi('Marc'); 

3. globally (e.g. in HTML):

   <script src="mod.js"></script> <script>mod.sayHi('Marc');</script> 

This method needs to get more publicity - if jQuery and co. started using it life would be much easier!
