Building a bot

Let us now look at the steps to build a chatbot. Here we will use the botbuilder library and create a bot using Node.js:

1. Create a Node.js project called foodie-bot:

> npm init

2. Install the two libraries that we need to use:

> npm install botbuilder --save
> npm install restify --save

3. Create a file named app.js. 
4. In app.js, paste the following code (from the Bot Framework tutorials):

var restify = require('restify');
var builder = require('botbuilder');

// Lets setup the Restify Server
var server = restify.createServer();
server.listen(process.env.port || process.env.PORT || 3978, function () {
   console.log('%s listening to %s', server.name, server.url); 
});


// Create chat connector for communicating with the Bot Framework Service
var connector = new builder.ChatConnector({
    appId: process.env.MICROSOFT_APP_ID,
    appPassword...
