[sdeleuze]

My pleasure 😉

[sdeleuze]

The talk recording should be available next week

[thiagoretondar]

Nice! From what I’ve followed on twitter the S1P was very good!

[thiagoretondar]

We need to promote more Kotlin! For me specially in the backend!

I’m building a lot of microservices with Kotlin+Spring and they just fit so well

[poohbar]

I was at a meetup at Pivotal the other day and expected a lot of Kotlin supporters. But after chatting with a few employees I learnt that most of Pivotal devs are still deeply entrenched in Java and there are just very few outliers like @sdeleuze that actually push Kotlin at all.

Was a pretty disappointing experience as on the outside it looks like Pivotal is embracing Kotlin.

[thiagoretondar]

@poohbar sad to hear that 😞

[thiagoretondar]

@sdeleuze @starbuxman is there any place where we can find some metrics of how many projects are created in start.spring.io using Kotlin?

[sdeleuze]

It is important to understand that there is much more inertia on server side than on mobile for example.

[sdeleuze]

@poohbar Spring committers are mostly still mostly on Java but a significant number of them currently are starting to use the language.

[sdeleuze]

I am not sure I can share the stats of start.spring.io, will ask.

[poohbar]

@sdeleuze gotcha, Pivotal is the leader in server-side Java so the more support and adoption we get from there the better for Kotlin.

[sdeleuze]

The most important feature is the Kotlin reference documentation that will extend to Boot and Security next year, this will have much more impact than any other feature (including Coroutines).

[sdeleuze]

It allows Java developer to compare typical Spring use case to Kotlin super easliy

[sdeleuze]

I am pretty sure this will be a big enabler

[sdeleuze]

Also Kotlin must provide middle term a different value proposition than just "use same stuff with other language". That what I work on with https://github.com/spring-projects-experimental/spring-fu.

[thiagoretondar]

I have been playing with spring kofu on personal projects only. Very good stuff, thank you

[sdeleuze]

Thanks, I will try to evolve it now that Spring Framework 5.2 is out.

[sdeleuze]

Coroutines are great but most our developers are still on Spring MVC + Tomcat so that's great but not enough to make people switch massively.

[sdeleuze]

To me the focus should be on more Kotlin refdoc and maturing Spring Boot Kotlin DSL (Kofu).

[sdeleuze]

And also a better Kotlin frontend story

[sdeleuze]

Hence my push for better Kotlin/JS story, Wasm, etc.

[thiagoretondar]

Is there a way we can help on Kotlin reference documentation? I’m sure this very important to make Kotlin adoption much easier

[sdeleuze]

Sure -> https://github.com/spring-projects/spring-boot/pull/18017

[sdeleuze]

You could ping the PR author to ask him if he can give you the redientials to contribute on his fork.
