I started with a boilerplate http4k project generated by the Project Wizard. I have a Web App user interface that needs to make REST calls to the http4k backend. This initially failed because CORS is required. As a result, I added the CORS Filter to the http4k project to get the Web App REST calls working. Alas, while CORS enabled the Web App UI to talk to the http4k server, this broke the simple Unit Test. I get an error like:

Ping test() FAILED

How can I enable CORS but also make the Unit Test work? I tried adding headers like:

.header("access-control-request-method", "GET")
              .header("origin", "<http://localhost:3000>"),

but I get a similar failure:

Is it normal that

Job.cancel()

throws a

CancellationException

itself? Or is this a bug in Ktor?

Hey, I’m trying to use arrow optics on Kotlin Multiplatform I have a Multiplatform module with JVM only, I’ve added the Ksp plugin and

kspCommonMainMetadata(libs.arrow.optics.ksp)
add("kspJvm", libs.arrow.optics.ksp)

then I’ve added

kotlin{ 
  sourceSets.all {
    kotlin.srcDir("build/generated/ksp/${this.name}/kotlin")
  }
}

and I see the code generated under • generated/ksp/jvm/jvmMain/kotlin • generated/ksp/metadata/commonMain/kotlin But the generated code is not resolved I believe I’m missing something in the setup (?)

Good morning. I’ve set up a new Project with: • Gradle 7.5.1 • Kotlin 1.7.20 • Android Gradle plugin 7.1.3 • Compose 1.3.0 • Compose compiler 1.3.2 Copying the setup from my previous project, but when building, I got

org.jetbrains.kotlin.backend.common.BackendException: Backend Internal error: Exception during IR lowering

…

The root cause java.lang.RuntimeException was thrown at: org.jetbrains.kotlin.backend.jvm.codegen.FunctionCodegen.generate(FunctionCodegen.kt:47)

Any idea? I’m already going crazy 😄 Currently, I got a couple of KMP modules and a couple of Android one, but I also tried changing the KMP to plain JVM, without any improvement

I've created the example KMM Hello World app described at Create your first multiplatform application. Next I created a new KMM Module via AndroidStudio's File->New->New Module...->KMM Shared Module, and named it kmmsharedmodule. I edited that to return the date using system libraries for each platform (referencing code snippets from Getting started with Kotlin Multiplatform.) Exactly how do I edit my build.gradle files to make the overall app dependent on kmmsharedmodule? I'm hoping it can be configured to automatically generate both Android and iOS libraries for this module, but I haven't found an example describing this specifically.

Is it possible to package native libraries (.so lib) in a shared module? Where would be the jnilib folder in Android? And what about iOS?

Hi. Is there any way to change default output folder path for KSP generated codes. Currently the generated files (using ksp annotation) are stored in folder

build/generated/ksp/variantname/kotlin

Can i able to change this path to a custom path bcoz i had problem with the variant naming.

How can I get a

ByteArray

from

UIImage

?

How do you cope with data classes with computed properties?

data class Animal(val type: String) {
  val isFavorite = type == "cat"
}

How do you set up the class in a test which just relies on its behavior, i.e. it's not the test for the class? Three approaches come to my mind: • Just construct the class explicitly and let the

isFavorite

property be actually computed. • Mock the class including all its properties (constructor and computed) • Use

spyk

and mock just the computed property (didn't try but I guess it should work)

Hello, please help I'm trying to use Koin in a KMM project with Voyager lib My Screen

@OptIn(ExperimentalVoyagerApi::class)
data object QuestionScreen : Screen {

    override val key : ScreenKey
        get() = KEY_QUESTION_SCREEN

    @Composable
    override fun Content() {
        val navigator = LocalNavigator.currentOrThrow

        val screenModel = navigator.getNavigatorScreenModel<QuestionScreenModel>()
        //var screenModel = getScreenModel<QuestionScreenModel>()

        //objects are a list of questions
        //val objects by screenModel.getObject().collectAsState()

        val state by screenModel.state.collectAsState()

My Koin

val screenModelsModule = module {
    factoryOf(::ListScreenModel)
    factoryOf(::DetailScreenModel)
    factoryOf(::QuestionScreenModel)
}

ViewModel

class QuestionScreenModel(
    questionDataSource: SqlDelightQuestionDataSource,
