Question

I have been playing around with node.js, and coming from a Java background, I am struggling to differentiate between modules and the typical concept of objects in JavaScript.

When implementing a modules, I am currently doing it this way:

// someModule.js
var privateVariable;
this.sampleFunction = function() {
   // ...
}

Now, the way I am using this module in another place is:

var moduleName = require('./someModule');

var foo = moduleName.sampleFunction();

I don’t know if this is the right way to do modular development in node.js – because I realized I am not actually using objects, like using new() – which I would need to do when I want to have collections etc. What is the right way to proceed here if I want a collection of person objects – how will my module and it’s definition look like?

Answer 1

// someModule.js
var privateVariable;
this.Person = function(firstName, lastName) {
   this.firstName = '...';
}

And then:

var moduleName = require('./someModule');

var foo = new moduleName.Person('foo', 'bar');
