Have you used RabbitMQ in any of your projects?

Yes, I have used RabbitMQ in several Node.js projects to facilitate message exchange between microservices and asynchronous task processing.

RabbitMQ is a message broker that supports various exchange models (queues, topics, direct exchanges).

Example of usage with the amqplib library:

const amqp = require('amqplib');

async function sendMessage() {
  const connection = await amqp.connect('amqp://localhost');
  const channel = await connection.createChannel();
  const queue = 'task_queue';

  await channel.assertQueue(queue, { durable: true });
  const msg = 'Hello RabbitMQ';

  channel.sendToQueue(queue, Buffer.from(msg), { persistent: true });
  console.log(" [x] Sent '%s'", msg);

  setTimeout(() => {
    channel.close();
    connection.close();
  }, 500);
}

sendMessage();

RabbitMQ helps unload main services, ensuring reliable message delivery and system scalability.
