Hey guys! Is Kotlin JS deprecated? Or are people using it actively?

It's not deprecated, but it's encouraged to use the multiplatform plugin instead of the kotlin-js one

Specifically to avoid JVM cold start at Lambda. But perhaps it's not exactly a good idea

The `kotlin-frontend` Gradle plugin is deprecated, but Kotlin/JS itself is very much still active as part of the multiplatform plugin. The docs could definitely use some work

I’ve actually used Kotlin/JS for Node Lambdas, it works pretty well. Just a toy project, but I made a simple Slackbot with it, though getting it compiled and deployed was a bit of a pain

Perhaps just plain Kotlin and JVM is not that hard to achieve

the Jetbrains team is working on Kotless, which looks like a good approach for using Kotlin in serverless apps, but I haven’t tried it out for myself yet <https://github.com/JetBrains/kotless>

Kotless doesn't escape the cold start tho

That's the main issue I'm trying to handle

It has auto-warming capabilities. You’ll never be able to fully remove the cold-start, even in a Node lambda

Node starts faster, doesn't it? I read some benchmarks, that's why I aimed to go for it

Yeah it definitely does start faster than a JVM lambda, but the cold-start was still noticeable when I was playing around with my Kotlin-Node lambdas

<@UB9K6R4JH> Kotlin/JS is alive, to try it you can start from <https://kotlinlang.org/docs/reference/js-project-setup.html>
And don’t hesitate to ask any question on the dedicated channel <#C0B8L3U69|javascript>

<@UB9K6R4JH> Node start faster, but there it is still some time. Autowarm approach solves issue to some extent.
Still, in Kotless we consider support of JS in nearest future
