This repository contains sample code for a talk given by Christian Folie and Daniel Weller at the DDD Vienna meetup on September 28, 2023.
You can find the slides for our talk on Miro and in this repository.
The repository contains the code of a sample application developed according to strategic domain-driven design (DDD) principles.
The intended purpose of the application is in the logistics domain, more precisely: to aggregate GPS signals (published by trucks that perform transports of goods) and forward them to customers, so that the customers are aware of the positions of the trucks.
The domain, and hence our application, is called signals.
Since iteration and evolution are core aspects of software development in general, and DDD in particular, the repository contains 3 versions of the signals domain, based on the passing of time:
- an early version,
- a "mid" version, and
- a late version.
These versions are modelled as branches in this git repository.
The intention is to show how how our domain code evolved over time. Each version is usable (dev experience, deployment, ...) in a standalone way - just check out one of the branches and explore it!
To see the changes from one version to another, you can try
diff2html, e.g. diff2html -- early mid to
show the diff from the early to the mid version.
