A simple micro services architecture that runs on NodeJS on ExpressJS framework using Sequelize for ORM to a MySQL database, and occasionally sends notifications to a queue on RabbitMQ. There is also a consumer service that listens to the notifications from the queue on RabbitMQ.

You can simply run the following commands with Docker Desktop & git installed on your machine to start this microservices project with dummy data included!
git clone https://github.com/pegasuspect/TaskMicroServices.git
cd TaskMicroServices;
docker-compose build
docker-compose up -d
You will need to restart the api, and the consumer services after database and RabbitMQ Broker services started, due to premature connection requests. This could be prevented with a wait-for-it shell script. It would be out-of-scope of this project and complicate it unnecessarily. Instead a simple restart of the server & RabbitMQ consumer fixes this issue.
For individual service testing and development you can also find docker-compose files inside the subfolders that correspond to the micro service.
Each service is seperated in their own folder. Each folder has a readme file for instructions on how to intialize and run locally.
