RabbitMQ Chat Application

This repository contains a simple chat application built with RabbitMQ that allows two users to communicate with each other in real-time.

Introduction

This project demonstrates how to implement a chat application using RabbitMQ messaging broker in a Node.js environment. In this application, users can exchange messages asynchronously using RabbitMQ queues.

Getting Started

To run this chat application, follow these steps:

1. Start RabbitMQ using Docker: Ensure that Docker is installed on your machine. Open a terminal and run the following command to start RabbitMQ in a Docker container:

   docker run -it --rm --name rabbitmq -p 5672:5672 -p 15672:15672 rabbitmq:3.13-management

   This command will download and start a RabbitMQ container with the management plugin enabled. Port 5672 is used for the AMQP protocol, while port 15672 is used for accessing the RabbitMQ management UI.

2. Clone the Repository: Clone this repository to your local machine.

3. Install Dependencies: Navigate to the project directory and run the following command to install dependencies:

   npm install

4. Start User1 (Publisher): Open a terminal window/tab, navigate to the project directory, and run the following command:

   node user1.js

5. Start User2 (Subscriber): Open another terminal window/tab, navigate to the project directory, and run the following command:

   node user2.js

6. Begin Chatting: Start typing your messages in each user's terminal window/tab. Messages will be exchanged between users in real-time. You will receive an acknowledgment when the other user receives your message.

Screenshots

Below are screenshots demonstrating the chat application in action:

Message Format and Acknowledgment

• Sending Messages: When sending a message, you will see a timestamp indicating when the message was sent and an acknowledgment if the other user received the message successfully.

  Example:

Send message to user2 (or "exit" to quit): hi from user1
[User2 Recived Message][2:53:45 PM]: hi from user1

• Receiving Messages: When receiving a message, you will see a timestamp indicating when the message was received and the content of the message.

Example:

Msg received from User1 [2:53:45 PM]: hi from user1

How It Works

In this application, each user acts as both a publisher and a subscriber. Messages sent by one user are published to a RabbitMQ queue, and the other user subscribes to that queue to receive the messages. RabbitMQ facilitates communication between users in real-time.

Example Applications

Beyond this basic chat application, RabbitMQ can be used in various applications, such as:

• Real-time collaboration tools
• Multi-player gaming applications
• Distributed task queues for processing jobs asynchronously
