Project Setup Instructions

Follow the steps below to set up and run the project:

Step 1: Clone the Repository

git clone

Step 2: Install Dependencies

cd create a new .env file and paste these contents

MONGO_URI=mongodb://localhost:27017/polls PORT=3000

npm init -y npm i

Step 3: Get Your IPv4 Address

Run the following command to find your IPv4 address:

ipconfig

Copy the IPv4 address of your Wireless LAN (e.g., 192.168.xx.xx) if you are on WiFi.

Step 4: Update Configuration Files

Open the project folder in your code editor:

1. Edit docker-compose.yaml:

- Replace <PRIVATE_IP> with your IPv4 address in two places.

2. Edit client.js:

- Update the brokers array with your IPv4 address.

Step 5: Start Docker Containers

Open Docker Desktop and run the following command to spin up the containers:

docker compose -f docker-compose.yaml up

Wait until all containers are successfully initialized.

Step 6: Start the Server

Run the following command to start the server:

node server.js

Create a poll, e.g., "Who is going to win?" with options like ind, pak, nz, aus.

Stop the application using Ctrl+C.

Step 7: View Poll in MongoDB

Open MongoDB, navigate to the polls database, and locate the poll collection.

Copy the _id of the created poll.

Step 8: Create the Topic and Partition

Open a new terminal tab and run:

node admin.js <poll_id>

(Replace <poll_id> with the _id you copied earlier.)

Step 9: Start the Application Components

Open new terminal tabs and run the following commands:

node server.js node consumer.js <poll_id>

(Replace <poll_id> with the _id of the poll you copied earlier.)

Step 10: Access the Application

Open the application in your browser:

http://localhost:3000

Notes:

• When casting a vote, you can see:

• Now whenever you poll some team you can see which partition is assigned to it , which option have you selected and of which poll in that terminal where you run node consumer.js <PRIVATE_ID>
  

• The leaderboard is currently compatible with a single poll only
