Probably a basic question: But we want to launch a "background" task from KTor route. We can't get KTor to return the payload before everything completes. Even if we wrap the slow part (no need for the result) and do

launch(<http://Dispatchers.IO|Dispatchers.IO>) { ... }

It does return 200 fast, but wait with the payload till after launch completes. Any pointers on how to achieve this? 🙂

Hello from the Netherlands 👋 I have a question regarding Multiplatform. The client side of Ktor is already supporting mutliplatform usage and there is an effort in making the server have that as well. Does that mean that all plugins for either side are automatically supporting multiplatform too? If not, how can I find out which ones are or not?

Can I use ktor client js in ServiceWorker?

I’ve noticed that sometimes auto reload (

-t installDist

) would cause the page to load forever after a change is made. The only way to fix this is by stopping the server and running it again. It has started becoming much more frequent lately. Does anyone else get that?

I am trying to send the generated Template<FlowContent> as a text response (I do not want to send the full HtmlTemplate). So far I have got below:

fun Route.test() {
    get("/test") {
        call.respondText(
            buildString {
                appendHTML().div {
                    insert(TestTemplate(), TemplatePlaceholder())
                }
            }
        )
    }
}

To make it work I have to wrap my TestTemplate in another div.

<div>
  <div>this is the element I want to get, without the outer element</div>
</div>

Is there a way of doing it so I can send the actual template only, so I can get below:

<div>this is the element I want to get, without the outer element</div>

Hello friends, what are you using for error monitoring? Bugsnag, Raygun, Sentry ? What's the experience of using them with ktor like?

@hhariri is it possible to change client artifact naming before last 2.0.0 is released? I think it is antintuitive that iOS client is used in more placed than iOS. Maybe renaming it to

darwin

for example. in general I find difficult to know how to setup a project which targets everything and uses a ktor client

Hi all, I published, to my maven local, the latest main branch in order to have 2.0.0-SNAPSHOT with Kotlin 1.6.0 (and a particular PR). In a project of mine where I declare

ktor-io

and

ktor-network

as implementation dependencies for my

common

source set, I now have an error "Could not resolve io.ktor:ktor-io:2.0.0-SNAPSHOT" that I don't understand. I found lots of similar errors in the Slack search but none hints me at what the problem is. This was working fine when I was using ktor 1.6.4-SNAPSHOT and Kotlin 1.5.31. (Gradle configuration and full error in thread.) Does anyone know what can be the problem ? Thanks in advance for you help.

Hello 👋 After updating ktor to 1.6.5 my tests have started failing with the exception

java.lang.NoSuchMethodError: java.nio.ByteBuffer.limit(I)Ljava/nio/ByteBuffer;

using ktor-server-tests. I've not been able to find any other reports of this error here or on YouTrack. In the failing tests I'm making a mock request using

io.ktor.server.testing.handleRequest

. This has been working fine up until 1.6.5 Any ideas on what might cause this? I've added more details in thread. Edit: It seems it could be the JDK version, tests fail on 8 but not on 17. My JVM target is 1.8 and I'm dependent on kotlin-stdlib-jdk8

i have a question regarding KTOR, is there any way to plugin in an engine that implements a non-HTTP protocol? KTOR looks really nice and i'd like it to be able to support a request/response framework that is proprietary.

Hi, I am new to KTOR and was trying to understand if we can send only status and empty body with ktor server. I was not able to find anything in docs regarding this. Thanks in advance!

We're using

staticRootFolder

right now as part of Ktor server. Not sure this question makes sense....but wondering if there should be way to specify multiple folders?

i am trying to use ktor 2.0 eap and kotlin 1.6.0 to build a mingw64 binary from linux.. lld fails because it cannot find

-lcurl

.. which dependency do i need to install ? i assume some

mingw-curl

or is this something to be configured in the buildscript ? for now i am trying this in archlinux on WSL2, because i can easily try the binaries on the host

Hi all, I am following https://ktor.io/docs/testing.html#hocon guide on testing, the issue I am facing is when I do

withApplication(testEnv)

it doesn't load my module that is defined in

application.conf

but when I do

withTestApplication(Application::main)

it loads the module but the configuration is missing, not sure what am I doing wrong here?

Adding annotations to the type parameter of

HttpClient.get<T>()

causes compilation to fail with

Annotated types are not supported in typeOf

Failed to find anything related on google/youtrack/github . Filed a YT-issue here, but would be happy to close if someone can help me figure out what I’m doing wrong, or why this shouldn’t work, in general..

I'm working on a project that uses Ktor and Hibernate. Currently the project can only run using the gradle Shadow plugin. This however breaks hot reloading, since all classes are compiled into a jar file, preventing ktor from picking up changes. If I run without the Shadow plugin, then I get a '<Entity> is not mapped' message from Hibernate. Does anyone have a similar setup where they managed to get the auto reload functionality to work?

Is there a way to include ktor’s dependency to nativeMain sourceSet? I have tried looking for it but only have been able to find it for macOs which apparently uses the same client as iOS.

Hi, at my ktor client I want to transform the server response to a custom one. I am intercepting

HttpResponsePipeline.Transform

for that. I want to know if we can parse error response from server as well at this point? Any help would be great! Code in thread.

Hey there, I am happy to present you an EventStoreDB Ktor-Server-Plugin. This Plugin is an seamless integration into the world of Ktor Server for the JVM.

Hello, what are the differences (pros/cons) of a ktor backend on Kotlin Native vs GraalVM Native Image ? (Assume Ktor 2.0) Thanka

So I was trying out ktor 2.0 on K\N and it worked as expected with the old MM, but with the new one, I get the following error. It looks similar to KTOR-2947, but I'm not sure if it's the same one. Should I create an issue?

Hi all, I'm having trouble with ktor's hot reload. My procedure is as follows: • run terminal> ./gradlew run • other terminal> ./gradlew -t build -x test -i • <hit endpoint> • run terminal> [12:38:06.094] DefaultDispatcher-worker-1 co.example.TestController Hot reload test • <update log to log.error("Hot reload test 3")> • run terminal> ktor.application Changes in application detected. • run terminal> Responding at http://0.0.0.0:11111 • <hit endpoint> • run terminal> [12:38:06.094] DefaultDispatcher-worker-1 co.example.TestController Hot reload test It appears to pick up the changes, but doesn't load in the updated classes. There doesn't seem to be a lot of configuration required, so I'm not sure what I could be missing?

Why wasn't KTOR-3358 fix included in 1.6.6? Or maybe it was?

is there a way to consume request body 2 times? or should I consume it as a string (to get whole request and log it for debugging) and then manually deserialize it into an object?

Has anyone run their ktor app on a digital ocean servlet? Not sure if I am doing something wrong, but running

./gradlew run

makes gradle get stuck. Currently at 8minutes in

hi, i have a problem about implementing https://github.com/papsign/Ktor-OpenAPI-Generator library for swagger. But after launching swagger-ui i'm facing a bug: Serializing collections of different element types is not yet supported. Selected serializers: [com.papsign.ktor.openapigen.model.schema.DataFormat, kotlin.Boolean, com.papsign.ktor.openapigen.model.schema.DataType]

does anyone have a working ktor-client-native sample ? this one: https://github.com/ktorio/ktor-samples/tree/main/native-client is not finding some dependencies apparently, upgrading to a newer ABI version and upgrade to kotlin 1.6.0

Caused by: org.koin.core.error.NoBeanDefFoundException: |- No definition found for class:'com.emirhan.controller.UserDataSourceImp'. Check your definitions!

Is anyone get this error about koin di?

How can I send files with Ktor client and FormData in KotlinJS? I receive files as

FileList

(which contains the actual Files) from React Input of type

file

. But I haven't found a way to append them to FormData. I tried using the

org.w3c.xhr.FormData

but I get the error

IllegalStateException: Fail to serialize body. Content has type: class null, but OutgoingContent expected.

But when I try to use the Ktors

io.ktor.client.request.forms

FormData, there is no override for

append

that accepts File type
