Playing with domain models in code
Main Conference - Hands-on Lab
Nico Krijnen and Jettro Coenradie
- Thursday 8 from 11:00 until 13:00 in Room 2
(This is a hands-on lab with limited capacity)
Two brains, one domain, one laptop, and a guarantee for 2 hours of fun and learning. You’ll go back to basics. Talking about the domain, designing the model and explore coding the model in Java or Kotlin with close to no libraries.
This is a hands-on coding workshop where you will work in pairs together with other participants. Your base will be the output of an EventStorming session and some context about the domain that you'll be modeling. Together, you'll play around, modeling parts of the domain in code, using tests to guide your design.
A starter project will be provided to get you up and running quickly, you can choose between Java or Kotlin. All you have to bring is a laptop with a recent version of IntelliJ installed (only one laptop per pair is needed). Throughout the workshop, pairs will share their approach so we can all learn from each other.
What you will learn:
- Why you need to start by understanding the problem before you start coding.
- How to 'sketch' in code and tease out a model bit by bit.
- Not to be afraid to throw away the model and sketch again.
Bring a laptop and make sure you install IntelliJ on it beforehand so you can have a running start. All preparation instructions will be in the following github repo: https://github.com/nkrijnen/workshop-ddd-europe-2023-06
