This is a small service modeling a statemachine that handles order events and will send notifications upon different transitions.
this app is a side-car to the article series "Ein Event-getriebenes System implementieren". The series consists of 3 parts. For each part I created or will create a Git tag so that you can restore the right state of the app for the corresponding article.
git checkout part_1 for the first part.
git checkout part_2 for the second part.
...
You get the idea. ;)
