Node.js and RabbitMQ Microservices

This guide demonstrates building microservices for an e-commerce platform using Node.js and RabbitMQ, focusing on a scenario where a product purchase triggers a stock update.

1. Introduction to E-Commerce Microservices with RabbitMQ

In an e-commerce setting, different microservices handle distinct functionalities. RabbitMQ, a popular message broker, facilitates communication between these services. We’ll create an Order Service (Producer) and a Stock Service (Consumer).

2. Setting Up the Environment

Ensure Node.js is installed and set up RabbitMQ. You can use Docker for running RabbitMQ locally.

3. Running RabbitMQ with Docker

Start RabbitMQ using Docker:

docker run -d --hostname my-rabbit --name some-rabbit -p 5672:5672 -p 15672:15672 rabbitmq:3-management

This command runs RabbitMQ and exposes the management interface on port 15672.

4. Creating the Order Service (Producer)

The Order Service will simulate a product purchase and send a message to the Stock Service.
