🛒🌐 eShop

The aim of this project is to be a proof-of-concept using Hexagonal Architecture (Ports-and-adapters) applying DDD in Go 🔥

The code will be reviewed over time to time while I will introduce new concepts about the Hexagonal Architecture or DDD and new features to it; so for sure will be refactored several times.

👩‍💻 Project

The idea of this project is to support an E-Commerce called eShop (super original 🙄). It has to provide a user management system and an order and product catalogue.

The language chosen for this has been Go and the database PostgreSQL. For the simplicity of the case I've added a docker-compose to create the db automatically and a Makefile with a few commands described above ✨

📐 Architecture

As mentioned before, the project it's using the Hexagonal Architecture and the layers are 📁

• application - it contains the application services (the use cases).

• domain - it defines the core of our applications; it contains the entities, the factories and the repositories interfaces.

• infrastructure - it contains the implementation of the repositories defined in the domain and the api definition (router and handlers).

• cmd - the multiple commands offered by the project.

📝 Commands

Use docker-compose up to start the database. Use make run to start the server. Use make migrations to run the migrations.
