RabbitMQ Microservices

This repository demonstrates a small microservices setup built with Node.js, RabbitMQ, and Redis. The services run together using Docker Compose.

Services

• web: Browser-facing UI on http://localhost:3000
• api: HTTP API on http://localhost:4000
• api-worker: Background worker that stores results in Redis
• special-worker: Background worker that transforms queued jobs
• redis: Shared inmemory data store
• rabbitmq: Message broker with management UI on http://localhost:15672

Run The Stack

1. Start everything from the repository root:

   docker compose up --build

2. Open the web app in your browser: http://localhost:3000. Sending a JSON message should result in the same message with reverted keys and values.

3. Optional: open the RabbitMQ management UI and log in with the default guest/guest credentials: http://localhost:15672

How It Works

• web sends jobs to RabbitMQ.
• special-worker consumes the job, processes it, and publishes the result back.
• api-worker stores the final result in Redis.
• api exposes the HTTP endpoint used to retrieve stored job results.

Notes

• The containers are configured to talk to each other through Compose service names.
• If you change ports or broker settings, update docker-compose.yml and the service environment variables together.
