POC - Hexagonal Architecture using PostgresSQL and MongoDB

Most of the code were simplified to make it easier to understand.

Description

This is a simple application to show how to implement a Hexagonal Architecture using one Driver Adapter, the go-chi library, and two Driven Adapters, PostgresSQL and MongoDB.

The code can switch between the two databases follwing the ports and adapters concept.

Requirements

• Docker
• Docker Compose
• Go

How to Run

• First, run the databases using Docker Compose:

docker-compose up -d

• Then, run the application:

go run cmd/main.go

How to Test

There are four endpoints available, two for each database connection:

• PostgreSQL:
  • POST /v1/games
  • GET /v1/games/{id}
• MongoDB:
  • POST /v2/games
  • GET /v2/games/{id}

---

The POST endpoints receive a JSON body with the following structure:

{
  "title": "Uncharted",
}

And return an ID for the created game.

---

The GET endpoints receive an ID as a path parameter from a game created in the corresponding database and return a JSON body with the following structure:

{
  "title": "Uncharted",
}
