Go - DDD Onion Project Structure

This project is a simple example of how to structure a Go project using the DDD (Domain-Driven Design) and Onion Architecture concepts.

The project is a simple API that allows you to handle orders.

The project is used as reference for my talk about DDD and Onion Architecture in Go.

Any suggestions or improvements are welcome.
