Super nice, Daniel. Please keep the Kotlin content rolling. Highly appreciated here!

[@TimSchraepen]

Nice overview of different kinds of Validation with increasing levels of revealing intent.

[@willmanuelleytonlopez3189]

It's an elegant solution! I like this approach, great content.

Hey man, thank you very much for your videos. I wanted to ask is it going to be any tutorial of akka+kotlin?

[@rockthejvm]

probably not; Akka + Kotlin would be the same as Akka + Java

[@mahyarmlk7964]

Great content 👍

[@neyasbit]

💣 Need more!

I wonder how this would look like in a DDD fashion, where in changing the DTO to the domain model the domain validation is performed inside the domain, and other validations inside the application/controller layer, which is then persisted.
I'll give it a try to rewrite my logic in this style! I think it would make it cleaner ( if I manage to lol)

Você já usou o Framework UDASH ele usa Scala.

"never use double for money"... what should we use instead?

[@rockthejvm]

Use specialized money types (many libraries for it)

[@TimSchraepen]

Mentions we’ll model events, doesn’t use past tense to describe them. *triggered* 😅😅😅

[@rockthejvm]

Technically, as described, they're _commands_
