#eventsourcing — Public Fediverse posts

RE: https://mastodon.social/@venkats/116568410481331830

I’m not only presenting two talks (one is a game, guess what it is), but also thrilled to do a workshop on my current passion: #EventSourcing and #DomainDrivenDesign #Java

Looking for something to watch during the weekend? What about a lighthearted intro to #EventSourcing https://m.youtube.com/watch?v=SDXdcymKv-8 ? 😎

It should give you a practical start to the most important concepts and also a good chance to learn #TypeScript modelling and how #Emmett can help! 🙂

One of the reasons why #EventSourcing is not (yet?) mainstream is a lack of trust that it works on the production. Mostly, that comes from being a bit different from the traditional approach.

That's why I made testing tooling a core part of #Emmett. You don't need to install anything besides the library. When you install core package, you also get testing tooling for components.

I believe that #EventSourcing is great for testing. It aligns greatly with Behaviour-driven Design principles.

The last 4 days were intensive. 4 afternoon sessions about #EventSourcing (morning one for the attendees).

It was also my first one with explaining also #Emmett as a solution to make working with Event Sourcing easier accessible. Great!

And those are the best types of workshops: done for practitioners that have a real business need and using it in their real projects.

Plus seeing others building systems based on tools you build is special.

I hope to have more of those to come!

#EventSourcing in #NodeJs just got better with new #Emmett features!

#PostgreSQL event store now has the first version of async subscriptions notifying about appended events. Thanks to that, you can now handle asynchronous workflows, integrations and projections. It's still experimental, but it works. See: https://github.com/event-driven-io/emmett/pull/128
