Requirejs and Commonjs crossmodule standard boilerplate

01 moduleA (return value).js

(typeof define==="function"?define:function(f){var r=f(require,exports,module);module.exports=(r!==void 0?r:module.exports);})(function(require,exports,module){
  return 27;
})

02 moduleB (set the module.exports).js

(typeof define==="function"?define:function(f){var r=f(require,exports,module);module.exports=(r!==void 0?r:module.exports);})(function(require,exports,module){
  module.exports = 27;
})

03 use in node.js

console.log(require('moduleA')); // 27

04 use in require.js

define(['moduleA'], function(moduleA){
  console.log(moduleA); // 27
})

05 preferred way to use in require.js

define(function(require, exports, module){
  console.log(require('moduleA')); // 27
})

Module we are making:

• moduleA.js: returning the module;
• moduleB.js: setting the module.exports variable;

Both way works the same. But remember to don't do both: you should not return a module and also set the module.exports variable;
