A modern programming language that makes developers happier.

I've created a checkPostOwnershipWebFilter (checkPostOwnership) to check if the Post to be updated or deleted is owned by the logged in user. How does it look to you ? Could I do better ? : <https://github.com/danygiguere/spring-boot-3-reactive-with-kotlin-coroutines/commit/ad39b35d255afc55e6279dcae974490fd0838584#diff-c6813dabf1781382cf7859fffb32b286c1c3fa88be7d712bac2149b3894512d8R36|https://github.com/danygiguere/spring-boot-3-reactive-with-kotlin-coroutines/commit/ad39b35d255afc55e6279dcae974490fd0838584#diff-c6813[…]94512d8R36>

It looks good; nothing particularly wrong, but I left some minor comments.

tiny general tip: Spring nowadays has handful of Kotlin utils making it easier to integrate with kotlin-first features.
I would guess most of it is listed in <https://docs.spring.io/spring-framework/reference/languages/kotlin.html|this part of the docs> and it's worth giving it a look sometimes :slightly_smiling_face:

For your case, <https://github.com/spring-projects/spring-framework/blob/main/spring-web/src/main/kotlin/org/springframework/web/server/CoWebFilter.kt|CoWebFilter> could be used instead of regular `WebFilter` to save you from dealing with Reactor types yourself.
There are also mini extensions like <https://github.com/spring-projects/spring-framework/blob/b699b65b40a0299d4845c2d0160ce1a0145d85d4/spring-web/src/main/kotlin/org/springframework/web/server/ServerWebExchangeExtensions.kt#L50|ServerWebExchange.awaitPrincipal> which could come in handy in your case
