Code Sample for a NodeJS Module using Module.Exports

Save the code as “room.js”.

module.exports = {
  windowsCount: 0,
  doorsCount: 0,
  LARGEROOM: {doorsCount: 2, windowsCount: 2},
  SMALLROOM: {doorsCount: 1, windowsCount: 1},
  getDoorsCount: function () {
    return ++this.doorsCount;
  getWindowsCount: function() {
    return ++this.windowsCount;    
  isLargeRoom: function(config) {
    if(config.doorsCount >= this.LARGEROOM.doorsCount && config.windowsCount >= this.LARGEROOM.windowsCount) {
      return true;
    return false;
  isSmallRoom: function(config) {
    if(config.doorsCount <= this.SMALLROOM.doorsCount && config.windowsCount <= this.SMALLROOM.windowsCount) {
      return true;
    return false;
Code to Execute Module

Following code could be used to execute above module using command such as “node main.js”. Save the file below as “main.js” in the same folder as “room.js”.

var r = require("./room.js");
console.log("Total no of doors: " + r.getDoorsCount());
console.log("Total no of windows: " + r.getWindowsCount());

var roomSize = r.isLargeRoom({doorsCount:2, windowsCount:3});
console.log(roomSize === true?"Large room":"Small room");

Above will print “Large room”.
