Help,please.
Here is my action
git push heroku clone mastergit https://github.com/heroku/node-js-getting-started.git
cd node-js-getting-started
npm install
npm install node-telegram-bot-api
-save
heroku create.
Create index.js,bot.js,web.js
// index.js//
require('./bot');
require('./web');
//end//
//web.js//
var express = require('express');
var packageInfo = require('./package.json');

var app = express();

app.get('/', function (req, res) {
 Res. json({ version: packageInfo.version });
});

var server = app.listen(process.env.PORT || 5000, function () {
 var host = server.address().address;
 var port = server.address().port;

 console.log('Web server started at http://%s:%s', host, port);
});
//end//
//bot.js//
var token = 'XXX'; 
var Bot = require('node-telegram-bot-api'),
 bot = new Bot(token, { polling: true });
bot.onText(/\/echo/, (msg, match) => {
 bot.sendMessage(msg.chat.id, 'You said' + match[1])
});
