Sample code used during GeeksHubs online meetup talk 23/04/2020.

Simple ticketing system using concepts of Hexagonal Architecture and leveraging separation of concerns.

The code is divided in two main layers:

Core

• Entities: Business Objects
• Repositories: Interfaces to interact with the entities
• Interactors: Business logic, actions that the system can perform.

Inputs and Outputs

• DataSources: Outputs of our system implementing Repositories and connected to storage systems.
• Controllers: Inputs of our system encapsulating the transport layer. They should trigger the Interactors.

Note: The purpose of this code is to be used as a guide to explore hexagonal architecture and it is not supposed to run in production.

• Clone the repo git clone https://github.com/samuanv/hexagonal-architecture.git

• Install dependencies npm install

• Run mongo and mongoclient docker-compose up

• Add the data located in /mongo to a database called ticketing

• Start typescript server + nodemon npm run watch
