Hello everyone. I’d like to use Kotlin for a back end. Would you recommend Spring or Ktor ? and What is the orm for Spring ?

Spring: mostly hibernate, Ktor often Exposed

[Jacob]

This is the first I've heard of ktorm, does it have any relationship to ktor?

[dany giguere]

ya it’s an orm for ktor

[dany giguere]

kt orm

[Jacob]

Looks like ktor is developed by jetbrains. ktorm is not. I think the only relationship is that they both use kotlin

[dany giguere]

ya true

[dany giguere]

I’d like to see a built in ORM in ktor

[Jacob]

ktor is just web. spring has a lot more but it brings along a lot of legacy with it. Reading the docs still require an understanding of xml based config even though no one does that anymore

[Jacob]

ktorm looks like it hasn't been updated in a while. I would be suspicious of it

[Jacob]

You might want to look at micronaut. Similar to spring but less history to be aware of

[dany giguere]

let me look at it. But regarding Ktor, how do we do database queries (without ktorm) ?

[Robert Jaros]

Spring Boot works perfectly with Kotlin and non-blocking spring-data-r2dbc works nice with spring webflux and kotlin coroutines.

[hfhbd]

Ktor does not provide a built-in db or even ORM framework support. Ktor is "only" a web server. You are free to use any ORM framework.

[Jacob]

https://github.com/JetBrains/Exposed is an orm by the same people that develop ktor

[dany giguere]

Thanks a lot guys. I really want to get into learning Kotlin on the server side. Your input helps. 🙂

[dany giguere]

I think I’ll try this tutorial https://bettercoding.dev/kotlin/ktor-rest-api-exposed/ to learn Ktor with Exposed and Kodein (for depedency injections)

Ktorm was updated in May 2021. Hardly outdated and it works very well from my inexperienced perspective
