Day 20 (May 9th 2016)

A Logbook entry written by @tpierrain

My refactoring journey towards Hexagonal Architecture

After few debates on twitter and a blog post to clarify why Hexagonal Architecture != Layers in my opinion, I decided to show an example of code to the community in order to continue the discussion. Since I'm not allowed to push some code outside my company, I started to reawaken the #SORLunchBox pet project to make it hexagonal.

I took me few days since I could only work on it during the transports (metro, train,...) and few early mornings but it is almost ready now. I also draw some sketches to present what the SOR is in a nutshell and to present the hexagonal architecture - the projects.

Before someone is telling me: xkcd

I'd like to add few...

Disclaimers:

  • The #SORlunchbox project is quite young and immature implementation. As of today:

  • It support 1 financial instrument only (implicit within the code ;-(

  • Even if it's event driven, the code is mainly synchronous ;-(next step will be to make it reactive and thus asynchronous)

  • Watch only the CSharp code since the FSharp version is even younger
