Eventsourcing 101

by Bob

Sat Apr 28 2018

Last month I travelled to Romania to give a talk about event sourcing at CodeCamp in Iasi. The talk was a quick 101 on what eventsourcing is, why you might want to do it, and then I demoed how to implement and persist an eventsourced domain model.

Unfortunately there's no video from the conference, because I was extraordinarily handsome and especially witty that day, but I've just uploaded the video of my trial run at work.

Slides and code are up on Github in case you want to try the exercise yourself, or to impersonate me. I made a few changes after this trial run, but the video should be close enough that you can work it out. If not, you can email me - bob at and I'll try and help you out.

I'll be returning to this subject in the near future as part of the series on Ports and Adapters, but I've been a little busy with some other projects.
