#EventModeling #ES #CQRS #DDD

A complete #SpecDrivenDevelopment framework where the type system provides formal constraints and the Given-When-Then DSL provides executable examples - together forming a powerful foundation for building correct systems with #AI assistance. @fraktalio/fmodel-decider" target="_blank" rel="nofollow noopener">jsr.io/@fraktalio/fmo…

@michaelayoub @HowardL3 Super!!! 🙏 Kotlin and Rust are also supported. fmodel.fraktalio.com

@HowardL3 I love github.com/fraktalio/fmod… (shoutout @idugalic)

event sourcing is such an obviously superior pattern for most crud apps it's not even close.

We are exploring #DomainModeling in #TypeScript using the #FModel library on the @deno_land runtime. Check out this demo: github.com/fraktalio/fmod… 🚀 We are modeling #EventSourcing in the `Deno KV` database.

@johanhaleby We did a workshop at the AxonIQ 2024 conference. I can share the repository github.com/m1l4n54v1c/eve…

@idugalic I'd love to read more about this (do you have any resources?), I've only seen the "killing the aggregate" video. But if I've understood your example correctly, the way I see an aggregate, i.e. as a logical consistency boundary required to fulfill business invariants, then..

FWIW, I think I've finally figured out my flaw in thinking about what an aggregate is :) Definitions of "aggregate", including the one posed by @VaughnVernon, must be seen in a greater context, the context of DDD. While this is obvious in hindsight, it made me a bit confused.

@johanhaleby A state of the whole system is a Product/Composition of all these small states(yellow sticky notes). Why do we need these yellow stickies to take some form of Student or Course? Why do we filter the stream of events per aggregate ID only?

@johanhaleby No static boundaries upfront. Every command handler/function has its dynamic boundary, per need. Observe in the image how two different commands source their state based on different events (not by aggregate ID). There is no Student or Course aggregate!

@johanhaleby IMHO, the definition of the Aggregate (in the context of DDD) is influenced by OOP, so it is also in the context of OOP. FP gave me another perspective (and context) on that definition. Event Sourcing gave me another: There is no need for the fixed/upfront consistency boundary!

.. whether through methods or pure functions. In both cases, the aggregate’s consistency is maintained as a unit." What I like about this definition, given that it's right, is that it works for both OOP and FP and doesn't talk about "objects" (which is an overloaded term).
