You can see the progress here Twitter Bot Github. Start by creating an App in Twitter Application Manager. Once created get the following in you app’s dashboard:
  • Consumer Key
  • Consumer Secret
  • Access Token
  • Access Token Secret
Then create a Free Heroku Account here.

Lets Start

Now create to files called bot.js and package.json in a folder.

Packages Required

We will require the Twit package and Node but copy the following and change the details for your app.
  "name": "robATwitter",
  "version": "1.0.0",
  "description": "A twitter bot for my site Rob Askam",
  "main": "bot.js",
  "scripts": {
    "start": "node bot.js"
  "keywords": [
  "author": "Robert Askam",
  "license": "ISC",
  "dependencies": {
    "rss-tweet-bot": "^0.1.1",
    "twit": "^2.2.5",
    "path": "^0.12.7",
    "express": "^4.14.0"
  "engines": {
    "node": "7.9.0"

Bot File

Firstly to hide your keys process.env.[key name] and i will show you how to use them on Heroku. Change the
const stream =
track, these are what will be looked for and if found access the function.
const express = require('./node_modules/express');
const app = express();
const path = require('./node_modules/path');
app.set('port', (process.env.PORT || 5000));
app.get('/', function (request, response) {
    response.sendFile(path.join(__dirname + '/index.html'));
}).listen(app.get('port'), function () {
    console.log('App is running, server is listening on port ', app.get('port'));

const Twit = require('./node_modules/twit');
const TH = new Twit({ // Twit Handler
    consumer_key : process.env.consumer_key,
    consumer_secret : process.env.consumer_secret,
    access_token : process.env.access_token,
    access_token_secret : process.env.access_token_secret

const stream ='statuses/filter', {
    track: ['robert-askam', '','']

stream.on('tweet', (tweet) => {   
//This will like the tweet if contains the above keywords'favorites/create',{
    },function (err,response) { 
//This will retweet the tweet if it contains the above keywords'statuses/retweet/:id', {
     id: tweet.id_str
//This will add a rely to the selected tweet.'statuses/update', {
       status: `@${tweet.user.screen_name} Thanks for sharing :)`,
      in_reply_to_status_id: tweet.id_str 


Add a name for the App in your personal apps. In the Deployment method select GitHub and link it to your account and App name.
