Hey folks

Required is intended to be a simple user authentication application, where anyone can register using e-mail and password, and later login.

This project is more technical in nature. My intention when developing it was to validate, learn and consolidate some concepts, such as:

Use of SOLID principles and Clean Architecture principles to build Restful APIs with Node;
Consolidate a good standard structure for creating Restful APIs with Node;
Consolidating my knowledge about unit and integration tests in Node Restful APIs;
Learn a little more about Docker and Docker Compose, as well as their best practices;
Consolidate my knowledge of deploying back-end services in Node and databases using Railway;
To exercise the use of the development model brought by Next in version 13 (app folder);
Consolidate my knowledge in building localized sites and applications for various languages;
Consolidate a good way to persist user authentication on the server side.
