I was wondering why there was no GitHub Action to setup Kotlin cli compiler, so I've built one: https://github.com/marketplace/actions/setup-kotlin Sure, that's not required if you use Gradle, Maven etc, but for scripting it might be useful. You can also provide a script to the action which will directly be executed. I don't know if this is useful to anyone, but I can see uses in small scripts in your ci pipelines where you would prefer Kotlin over Bash or Python. (not sure if this is the right cannel for this)

Hello everyone, everything good? I'm using ktor and I want to use

"'Access-Control-Allow-Origin': '*'"

, has anyone done this?

Hello everyone, I've just joined this channel. and I'm developing Rest API server using ktor. I'm curious about that how do I allow to access files from Client side. From my understanding, there is static feature, it can provide static data such as resources, files, and so on. in static directory of this project. is it right? but it seems to be not enough for it. First of all, the client(Android App) sends some image files throgh MultiPart. the receive files are stored in specific directory, for instance (d:\\service\images\) The problem is that I don't know how to access above directory to download or load images in client side. My expected url is "" Is it possible to provide for ktor? Anyone have any ideas? Thanks in advance.

Hey guys! Does anyone here have an example of Ktor integration testing?

what’s the current best Kotlin vs Java article to point people to? 🙂

Hello all. I was just working on a full stack application with Kotlin and right now working on the backend. Kotlin + Spring combination looks good to me. Was just wondering whether I can use all the features of GraphQL properly with this combination because I didn't find any information regarding GraphQL on Spring's website.

Please anyone

I'm passing the Google rechapta token in the Header, and CORS is giving an error. has been blocked by CORS policy: Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource. What do I need to enable in CORS?

Speak up, guys! I'm putting together a clause where exposed this way

Hello guys. I am using kotlinx.serialization in my ktor api and have a data class as below.

@Serializable
data class User(
  var email: String = "", 
  @JsonIgnore var password: String = ""
)

Which annotation can i use on the password field to ignore it "only" in the http response but not within the application. For example Ignore it when:

get {
    call.respond(User("email", "some password"))
}

Don't ignore it when:

fun checkUserPassword(email: String) {
    val user = getUserPasswordFromDatabaseByEmail<User>(email)
    // The print below does not work (I want it to work since it is not yet part of the response)
    println(user.password)
}

Can anyone give example of kotlin spring and jwt.

Does anyone worked on ktor with AWS lambda, if so can you share a GitHub repo.

Hey everyone! I’m Egor, product manager in the Kotlin team. I’m conducting a series of interviews with newcomers in Kotlin for Server-side. I’m interested to talk both to people who had experience with server-side with other languages and to those who came from Android or somewhere else. My goals are to: - Understand how and why people decide to try Kotlin - Understand how exactly they try Kotlin for the first time - Collect pain points in their onboarding process If you’re interested to help our team make the onboarding process better – feel free to write me in direct messages :)

Hi everyone, I’m an android developer, Now I want to start a server project, I have decided to start with Ktor, so what IDE can compile Kotor (Or something like Ktor, ex: Http4k ...)? I used Android Studio for Android before, can I use it for server purpose?

Hi All 👋 Anyone know when this TODO will be updated? Need guidance on deploying Ktor to remote Ubuntu server - either a Docker deploy or other working Ktor + Linux server setup 🙏

Hello. I am a SpringBoot/Kotlin Backend developer. we have allready a lot of microservices in production already in our product. Now I am thinking to get a try on Ktor. our environmet is K8s / Openshift deployed with skaffold and Kusomize dockerize with Google Jib / one with Packt. from SpringBoot Gradle/Maven Plugin :). have maybe somebody already some success stories in a environment like this in production. I think about monitoring (actuator) Jeager tracing Hateoas Rest Apis etc.

Hello everyone, I'm James, an experienced Fullstack developer - I've written server side JVM code in Java, Scala, Clojure, and most recently - Kotlin. 👋

Hey guys, we have created a linter (checker + autofixer) for Kotlin with a huge number of rules. Will be great if you will support it at least with a very simple thing: star on a GitHub: https://github.com/cqfn/diKTat But it will be also great if you will have a chance try it in your CI/CD :) We are already added to awesome-kotlin and awesome-static-analysis, but still need some support from you!

Hi all!! Can I suppress kotlin compile warnings during gradle build via passing system property parameter something like:

-DkotlinOptions.suppressWarnings=true

?

hi all! does anyone know if it is possible to have different kotlin compiler options in gradle (like allWarningsAsErrors) for generated code and for project itself? what we try to solve is: we have swagger specs and generate client code from them, if we generate it to kotlin, the code is not passing allWarningsAsErrors 😞 but we want to enforce allWarningsAsErrors for our own code. i understand that it’s better to fix code generation, but it might take longer.

Hello Everyone, I'm Nurudeen an Android Developer recently exploring the awesome possibilities of Kotlin on the server with Ktor. It's been great so far.

Hi everybody I just completed a small server project using Ktor, now I want to run it on a leased server, so how can I package it as well as protect the source code, like creating a APKs on Android?

Can I create a Linux server on EC2 and deploy Ktor APIs to it? 🤔
