-The goal of this project is to implement an application called `order-app` to manage orders. For it, we will implement a back-end application called `order-api` using [`Spring Boot`](https://docs.spring.io/spring-boot/docs/current/reference/htmlsingle/) and a font-end application called `order-ui` using [ReactJS](https://reactjs.org/). Besides, we will use [`JWT Authentication`](https://en.wikipedia.org/wiki/JSON_Web_Token) to secure both applications.
