| 🛰️ About:

This application is an implementation of a Microservices Architecture using RabbitMQ for queue communication and the best practices of Clean Architecture, SOLID and DDD, all documented. Use Docker to handle the entire system structure.

💻 | Application:

Giving an overview, this architecture is divided into User Microservice and Email Microservice, each with its own databases, communication between them occurs through a broker which in this case is based on asynchronous queues managed by RabbitMQ

🕺 | User

| Repository: [ https://github.com/Samuel-Ricardo/ems_user ]

The main function of User Microservice is to list and register users in a database. When a user is saved in this MS, it publishes this event to the broker.

📧 | Email

| Repository: [ https://github.com/Samuel-Ricardo/ems_email ]

The main function of the Email Microservice is to send a welcome email to new users, for this it listens to the broker, when a created user event is published this MS consumes this event and sends an email to this new created user welcoming .

📮 | Broker

The broker is an intermediary between microservices, it receives events and store in a Queue Data Structure that is triggered and can be consumed by other microservices that are waiting for it to react.

  # After setup docker environment just run this commmand on root project folder:

  $ docker-compose up --build   # For First Time run this command

  $ docker-compose up           # to run project

  #Apps Running on:
