Perfect! Here's a complete README.md content tailored for your RabbitMQ Node.js project with topic exchange, one producer, and multiple consumers:

# My RabbitMQ App

## Description
This is a **Node.js application** demonstrating a **RabbitMQ Topic Exchange** setup with **one producer** and **multiple consumers**.  
Messages are published by the producer with a routing key and consumed by the appropriate consumer(s) based on binding patterns.

---

## Features
- Topic-based message routing with RabbitMQ.
- One producer sending messages.
- Multiple consumers (WhatsApp, Email, Telegram) listening to specific routing patterns.
- Easy to extend with additional channels.

---



## Installation

1. Clone the repository:

```bash
git clone <your-repo-url>
cd my-rabbitmq-app

2. Install dependencies:

npm install

3. Make sure RabbitMQ is running (default amqp://localhost).

---

Usage

Run Producer

npm run dev:producer

Run Consumers

npm run dev:consumer:whatsapp
npm run dev:consumer:email
npm run dev:consumer:telegram

You can run multiple consumers simultaneously to see the topic exchange in action.

---

Exchange & Routing

• Exchange Type: topic

• Example Routing Keys:

  • notify.new.whatsapp
  • notify.new.email
  • notify.new.telegram

Consumers bind queues to the exchange using patterns like:

notify.*.whatsapp
notify.*.email
notify.*.telegram

If you want, I can also **add badges, usage examples, and a diagram showing producer → exchange → multiple consumers** to make it GitHub-ready and more professional.  

Do you want me to add that?
