The method or variable defined in modules cannot be directly accessible by the outer world, that means you cannot call a module member from the external file. In order to access module member, we need to export the functions or variables of modules using module.exports method.

Syntax and usage:

// greet.js
var greet=function(){
console.log("hello World");
}
module.exports=greet;

//In app.js

var greet=require('./greet.js');

greet();
