This tutorial is all about making a Twitter bot using JavaScript / NodeJS, which helps you retweet certain hashtags along with a like. It helps you gain followers on your Twitter account. It will not happen all of a sudden — you will start seeing results after about 2 weeks.
How to gain Twitter followers
The below topics are covered in this blog -
1) How to increase Twitter followers?
2) How to gain Twitter followers?
3) How to get Twitter free unlimited retweet?
4) Free Twitter followers
5) How to gain followers on Twitter organically?
6) How to increase real Twitter followers?
7) Serverless hosting
8) Serverless deployment
9) Making a Twitter bot with JavaScript
10) Making a Twitter bot with NodeJS
11) AWS Lambda deployment
1. Apply for a Twitter Developer Account
First, you have to apply for a Twitter developer account if you haven't already. It takes 2–3 days to get activated. Once it is active:
Twitter Developer Account
2. Add Your Keys to the Config
You will get your consumer keys and authentication tokens. Grab your keys and tokens and paste them into the config file at config/default.json.
Twitter Bot with JavaScript
3. Run the Bot
Install the dependencies and run the handler:
npm install
node handler.js
For code-level access, I am providing the GitHub link below — you can clone it from there. If you like my article, please follow me on GitHub. If you have any doubts, watch my YouTube video.
Once the code is ready, I deploy this JavaScript function as a Lambda on AWS and trigger it every 2 hours. Why Lambda? Because AWS Lambda is serverless — there is no downtime, and I don't pay any extra amount to AWS. I only pay for what I consume. For me it works out very cheap, around 0.15 dollars a month or less. More details in the YouTube video below.

Continuous Integration is a process in which all development work is integrated as early as possible, with the resulting artefacts automatically built and tested. This blog walks through integrating Jenkins with Slack and email notifications, so your team is notified of every build on a Slack channel, and you get an email whenever a build fails.
Jenkins CI with Slack and Email Notification
The below topics are covered in this blog -
1) Introduction to Jenkins continuous integration
2) Creating a Slack account and incoming webhook
3) Configuring the Slack Notification plugin in Jenkins
4) Configuring email notification in Jenkins
5) Testing the setup
1. Introduction
Jenkins is an open-source continuous integration tool written in Java, used for building, testing, and reporting on isolated changes in a larger codebase in real time. It lets developers find defects and fix them rapidly through automated testing.
2. Create a Slack Account and Incoming Webhook
Slack is a chat platform that provides incoming webhooks, which let external systems post messages into a channel. We will use one so Jenkins can send build notifications into your Slack channel.
If you haven't created your Slack account yet, sign up first, then visit:
Treat this URL as a secret. Anyone who has it can post messages into your channel. Never commit it to a repository, paste it in a screenshot, or publish it.
You can test it with a curl command:
curl -X POST --data-urlencode \
'payload={"channel": "#codeztech-jenkins", "username": "webhookbot",
"text": "This is posted to #codeztech-jenkins from a bot named webhookbot.",
"icon_emoji": ":ghost:"}' \
https://hooks.slack.com/services/TXXXXXXXX/BXXXXXXXX/XXXXXXXXXXXXXXXXXXXXXXXX
Slack Webhook URL
3. Configure the Slack Notification Plugin in Jenkins
Make sure the Slack Notification plugin is installed from Manage Jenkins → Manage Plugins. You can download it directly from:
Then go to Manage Jenkins → Upload Plugin and restart Jenkins. I have made a full video on this, linked at the bottom of this post. Feel free to comment on my YouTube channel or here if you run into any issue.
Once restarted, go to Manage Jenkins → Configure System and scroll to the Slack section.
Base URL https://hooks.slack.com/services/
Team Subdomain your Slack workspace subdomain
Credential the webhook token, stored as a Jenkins secret
Channel #your-channel-name
You can find the team subdomain in your Slack URL path:
Slack - Incoming WebHook Team Subdomain
Add the credential and enter your channel name prefixed with # — the channel where you want all build notifications sent. Click Test Connection to confirm the setup works.
Configure Slack on Jenkins
4. Configure Email Notification in Jenkins
To configure email notification in Jenkins, go to Manage Jenkins → Configure System → E-mail Notification and use the following settings:
SMTP Server smtp.gmail.com
Default user e-mail your-address@gmail.com
SMTP Authentication checked
Username your-address@gmail.com
Password your app password (see below)
Use SSL checked
SMTP Port 465
Reply-To Address an alternate address
Do not use your normal Gmail password — Google will reject it. Generate an app password instead:
Step 1 — Sign in to Gmail and go to Manage your Google Account
Step 2 — Open the Security tab and find the sign-in section
Step 3 — Click App passwords and select the device or app
Step 4 — Generate the password and copy it
Paste that app password into the Jenkins password field, then click Test configuration to send a test email.

A Jenkins freestyle project is a repeatable build made up of build steps and post-build actions. You choose what runs at each stage, and there are dozens of standard plugins available to extend it. This blog walks through creating a freestyle job from scratch, pointing it at a Git repository, compiling a Java program, and checking the console output.
Jenkins create & build freestyle project
The below topics are covered in this blog -
1) What is a freestyle project in Jenkins?
2) Creating a new freestyle build job
3) Configuring source code management with Git
4) Adding a build step
5) Running the build and reading the console output
1. Freestyle Project in Jenkins
A Jenkins project consists of build steps and post-build actions. The actions you can perform fall into three places: the build step, the post-build action, or a Jenkins pipeline. There are a large number of standard plugins available to cover most common requirements.
2. Creating a Freestyle Build Job
To create a Jenkins freestyle job, log in to your Jenkins dashboard. If Jenkins is hosted locally, visit http://localhost:8080. If it is hosted elsewhere, use that URL instead.
Step 1
Click New Item in the top left corner of your dashboard.
Jenkins New Item
Step 2
Enter the name of the item, choose Freestyle project, and click OK.
Freestyle Project
Step 3
Enter the details of the project you want to set up.
Jenkins Project Details
Step 4
Under Source Code Management, enter your repository URL so Jenkins can clone it. For this example the URL is:
https://github.com/kriru/firstJava.git
Jenkins Setup Git Project
Step 5
Click Add build step → Execute Windows batch command and add the commands you want to run. In our case:
javac HelloWorld.java
java HelloWorld
On a Linux or macOS agent, use Execute shell instead of Execute Windows batch command — the two commands themselves stay the same.
Jenkins Build Windows Batch Command
Step 6
Click Apply & Save, then Build Now to check whether the build succeeds.
Jenkins Build Now
Jenkins Build Successful
Step 7
If you want to explore further, click Console Output to see the detailed result.
Jenkins Console Output
Congratulations — we have executed our HelloWorld program from Jenkins.

Amazon EC2 is one of the most used and most fundamental services in AWS, so it makes sense to start there when you are new to the platform. But the first question is: what is EC2 in AWS?
Amazon EC2 — Hosting a MEAN Stack Application
The below topics are covered in this blog -
1) What is EC2 in AWS?
2) The MEAN stack CRUD application
3) Architecture of the application
4) Installing MongoDB on an EC2 instance
5) Hosting the MEAN stack with PM2
1. What is EC2 in AWS?
To keep it simple:
EC2 is basically a virtual machine with its own CPU, RAM, and storage.
It lets you choose a platform — Windows, Linux, Ubuntu, and so on — when you launch the machine in the cloud.
Each virtual machine is called an instance, and you can start, stop, or terminate it whenever you like.
2. AWS EC2 MEAN Stack Application Screens
Here are a few screens from the MEAN stack CRUD application we are going to host on AWS EC2.
Insert
MEAN Stack CRUD Application — Insert
Update
MEAN Stack CRUD Application — Update
Delete
MEAN Stack CRUD Application — Delete
3. Architecture of the MEAN Stack Application
The diagram below shows the architecture we are setting up across two AWS instances. The frontend uses Angular, and every user interaction — create, read, update, delete — goes through Node.js.
MEAN Stack Application Architecture
Node.js acts as the mediator that talks to the MongoDB database and returns data to the frontend. We use two instances — one for the frontend and one for the backend.
Point the code at your instances. By default the projects use localhost. You need to replace that with your EC2 public IPs:
Backend — in db.js, set the MongoDB instance's public IP; in index.js, set the backend instance's public IP.
Frontend — in src/app/shared/person.services.ts, change localhost to the backend instance's public IP:
vi src/app/shared/person.services.ts
One important note: pointing the frontend at a raw EC2 public IP hardcodes an address that changes every time the instance restarts, unless you attach an Elastic IP. For anything beyond a demo, put the backend behind a stable hostname or load balancer rather than baking the IP into your source.

The term MEAN stack refers to a collection of JavaScript-based technologies used to build web applications. MEAN stands for MongoDB, Express.js, Angular, and Node.js.
MEAN Stack Application
The below topics are covered in this blog -
1) Overview of the MEAN stack
2) What does CRUD stand for?
3) Architecture of the MEAN stack application
4) Building the Node.js backend
5) Building the Angular frontend
1. Overview of the MEAN Stack
MongoDB — MongoDB is a schema-less NoSQL database. It stores data in a binary JSON (BSON) format, which makes it easy to pass data between client and server. If you haven't seen my MongoDB tutorial yet, see my related post: Complete Guide to MongoDB.
Angular — Angular is a JavaScript framework developed by Google. It provides features like two-way binding, routing, sharing data between components, RxJS, and observables. In short, it is a complete solution for rapid frontend development.
Node.js — Node.js is a server-side JavaScript execution environment built on Google Chrome's V8 runtime. It helps you build highly scalable, concurrent applications quickly. See my related post: Complete Guide to Build a RESTful API with Node.js.
Express.js — Express is a lightweight framework for building web applications in Node.js. It provides a robust set of features for single- and multi-page apps and was inspired by the Ruby framework Sinatra. We use Express in Node.js as our web application framework.
2. What Does CRUD Stand For?
CRUD stands for Create, Read, Update, and Delete — the four basic operations of persistent storage.
CRUD Stands For
We are going to build an application that performs all four operations using the MEAN stack.
3. Architecture of the MEAN Stack Application
The diagram below shows the architecture of the application we are building. The frontend uses Angular, and every user interaction — create, read, update, delete — goes through Node.js.
MEAN Stack Application Architecture
Node.js acts as the mediator that talks to the MongoDB database and returns data to the frontend.
4. Building the Node.js Backend
Step 1 — Generate a package.json. Create a folder, then run:
mkdir meanstack_backend
cd meanstack_backend
npm init # press enter through the prompts
npm install body-parser cors express mongoose nodemon --save
Step 2 — Create the entry file, index.js:
const express = require('express');
const bodyParser = require('body-parser');
const cors = require('cors');
const mongoose = require('./db.js');
const personController = require('./controllers/personController.js');
var app = express();
app.use(bodyParser.json());
app.use(cors({ origin: 'http://localhost:4200' }));
// Application testing API
app.get('/app/testing', (req, res) => {
res.send({
"message": "App is working fine",
"status": 200
});
});
app.use('/person', personController);
app.listen(3000, () => console.log('Server connected to port: 3000'));
