Architecture API - Clean architecture

---

Introduction

This repository contains a starter template for user authentication and CRUD operations.

This API was inspired by some concepts from the hexagonal architecture work of Dr. Alistair Cockburn in an article he wrote in 2005.

Ports & Adapters is a pattern that promotes decoupling from technology and frameworks.
