Onion Architecture Presentation Resources

Thanks to everyone who attended my presentation at #SeattleCodeCamp this morning!

The code I demoed this morning is currently on the “develop” branch on github.

Here are some of the resources for further reading I alluded to.

I had some additional thoughts for future revisions of the presentation.

  1. OA is not just about coding to interfaces. It’s also about coding to the right category of interfaces.
  2. My presentation is in C#, but the same principles apply in any programming language. The implementation details in other languages may differ.
  3. Every recommended approach to Onion has a “fat” layer where the important code is. Other layers are basically façades and coordinators.
  4. In the future, I’d like to show my code diagram first, then show the code, then show the other Onion diagrams.
  5. I need to update my image for my code diagram as the font doesn’t show up well on washed out projectors.

I’d also like to find a DDD implementation of OA and at least one written in another language (not Java).
