About

This project is a hands-on freestyle exercise to demonstrate the use of microservices applied to a health care system. The goal is to obtain a proof of concept on using gRPC communication between SAGA pattern microservices and a API Gateway, which provides a http interface to the client.

Requirements

To run this project locally, you will need the following tools:

• Node.js - v18
• Make
• Docker
• Docker Compose

Configuring your local environment

We will use make to run the commands, Docker to build images and run our services in containers, and Docker Compose to orchestrate them.

Run the following command to setup all the environment and run the services:

make prepare

In addition, you can run the following:

• make stop to stop all containers
• make down to remove app containers
• make database to run the database container
• make migrate to run migrations
• make setup-db to run the database container and migrations
• make run-services to run the services containers
• make purge-all to stop and remove all containers, networks, images, and volumes
