Correct way of exporting module

This question already has an answer here:

What is the purpose of Node.js module.exports and how do you use it? 10 answers

Both methods of using module.exports or module.exports.FUNCTION_NAME are okay but the difference comes when you require these functions.

Let me show the difference using an Example.

a. Assigning function directly to module.exports

// mkdir.js
module.exports = function(){
       console.log("make directory function");
};

// app.js
var mkdir = require("mkdir.js");
mkdir(); // prints make directory function

b. Exporting function at property in module.exports

// mkdir.js
module.exports.first = function(){
                     console.log('make directory function');
};

// app.js
var mkdir = require('mkdir.js');
mkdir.mkdir(); // make directory function

Hope it helps!

module.exports = makeDir;

is the correct method if you are exporting only one object from javascript file.

IN CASE YOU NEED TO EXPORT MORE THAN ONE OBJECTS

var makeDir = {
 obj1 : function(){},
 obj2 : function(){}
}
module.exports = makeDir;

This way you can use makeDir.obj1 and makeDir.obj2 in other file.
