2. Node JS, NPM Package Manager.
3. Public Hosting Service IP/ Domain with supporting NodeJS Applications.
4. Skype Bot Id   Click here to get Skype Bot Id.
5. node   --version   v4.4.4, npm  -version   2.15.1

Step1: Creating the Empty NodeJS Project.

1. Create a Directory SkypeBot.  
2. cd to SkypeBot. 
3. Create an empty NodeJS Project with   'npm init'.

Step2: Download Require NodeJS Libraries.

1. npm  install restify --save
2. npm install botbuilder --save

const restify = require('restify');
const skype = require('skype-sdk');
const builder = require('botbuilder');

Note: skype-sdk is not available in npm package manager or you will get empty directory while downloading from npm package manager. download it from here.

Step3: Create and Initialize the Skype BotService with Default Configurations.

const botService = new skype.BotService({
    messaging: {
        botId: "28:f53d6e20-1e46-4cee-884d-***************",
        serverUrl : "https://apis.skype.com",
        requestTimeout : 15000,
        appId: 'f53d6e20-1e46-4cee-884d-************',
        appSecret: 'vFkWqyob2Tvdc**********'
    }
});


Step4: Create REST API with Restify Server.
const server = restify.createServer();

Step5: Create Skype Event Handler's. 

botService.on('contactAdded', (bot, data) => {

});

botService.on('personalMessage', (bot, data) => {

    //console.log(bot);
});
