KVision allows you to build modern web applications with the Kotlin language


KVision Logo


Object oriented web framework for Kotlin/JS.


CI API IR License: MIT Slack Discord

KVision allows you to build modern web applications with the Kotlin language, without any use of HTML, CSS or JavaScript. It gives you a rich hierarchy of ready to use GUI components, which can be used as builder blocks for the application UI.

KVision fully supports both reactive and imperative programming models. It gives you everything you may need for the state management of your apps.

KVision contains innovative connectivity interface for Ktor, Jooby, Spring Boot, Javalin, Vert.x and Micronaut frameworks on the server side, which allows to build fullstack applications with shared code for data model and business logic.

KVision is being actively developed. Please create an issue for any bugs or feature requests.

Sample code

class App : Application() {

    val state = ObservableValue("Hello world")

    override fun start() {
        root("root") {
            vPanel {
                h1(state) {
                button("Add an exclamation mark").onClick {
                    state.value += "!"


Examples and documentation

Ready to explore, rich set of KVision examples is available in the separate project.

See also the complete frontend implementation of RealWorld example application and a fullstack version built with Spring Webflux and R2DBC.

The comprehensive KVision guide is published on GitBook.

The API documentation, generated with new Dokka, is available at https://rjaros.github.io/kvision/index.html.

You can also look at KVision blog posts at dev.to and you can talk with KVision users and developers on Kotlin Slack #kvision channel and on the Discord server.

  • Dynamic Table Data

    Dynamic Table Data

    The following code used to work, but ceased to do so a while ago (I really should cover it better in tests!): (used to work = data was displayed)

     * Makes properties of delegate available for display in tabulator.
     * For regular TObjects these are members (properties).
     * For FixtureResults these are: result, resultClass etc.
     * Exposer bears some similarity to the JS "Revealing Module Pattern"
     * (see: https://addyosmani.com/resources/essentialjsdesignpatterns/book/),
     * but it goes further since it even reveals members of it's delegate.
    class Exposer(val delegate: TObject) {
        var iconName = ""
        var selected = false 
        fun dynamise(): dynamic {
            val thys = this.asDynamic()
            for (m in delegate.members) {
                val member = m.value
                if (member.memberType == MemberType.PROPERTY.type) {
                    val realValue = member.value
                    if (realValue != null) {
                        thys[member.id] = realValue.content
            iconName = IconManager.find(delegate.title)
            if (iconName == IconManager.DEFAULT_ICON) {
                iconName = IconManager.find(delegate.domainType)
            return thys
        // eg. for dataNucleusId
        fun get(propertyName: String): Any? {
            return this.delegate.getProperty(propertyName)?.value

    I added in @OptIn(ExperimentalJsExport::class) and @JsExport without success.

    Was there any change in KVision, Tabulator, or Kotlin that broke this code?

  • Gradle plugin refactor

    Gradle plugin refactor

    Hi, here's a first go at refactoring the plugin to make it

    1. more configurable (resolves #392)
    2. compatible with Gradle caching (resolve #393)

    I've only very briefly tested compatibility with Kotlin JS - see the included test project (open it independently, e.g. idea kvision-tools/kvision-gradle-plugin-test/)

    I wanted to share the progress to get feedback. I hope they make the plugin much more clear and understandable.


    • enabled Gradle build cache and parallel build. This is unrelated, but it really helps with development
    • bump com.gradle.plugin-publish (which means no need for META-INF prop file, so I've moved it)
    • share URL between Gradle plugin definition and Maven POM
    • created a new KVisionPlugin
    • create specific tasks for the tasks defined in KVisionGradleSubplugin
    • create KVisionExtension for shared plugin/task config
    • add kvision(...) dependency helper function
    • renamed the subproject directory to match the other subprojects


    • [x] Create some TestKit tests
    • [x] create a demo project for Kotlin MPP
    • [ ] Re-align KVisionGradleSubplugin and the new KVision plugin. I've kept the existing plugin in as a reference, but only one should remain.
    • [ ] Update the example projects
    • [ ] Update the documentation

  • Redux states - do they need to be serializable?

    Redux states - do they need to be serializable?

    Is there any specific reason why KVision's redux module should require serializable data classes? I'm running into a problem with a custom class of ObjectID from MongoDB. I've written a custom serializer for my class:

    @Serializer(forClass = ObjectID::class)
    object ObjectIDSerializer: KSerializer<ObjectID> {
        override val descriptor: SerialDescriptor =
        override fun serialize(encoder: Encoder, obj: ObjectID) {
        override fun deserialize(decoder: Decoder): ObjectID {
            return ObjectID(decoder.decodeString())

    but when I try to run it in the browser, I get Can't locate argument-less serializer for class null even though none of my variables in the redux state are nullable. Is it possible to remove the requirement for it to be serializable? Unless there is a specific reason why it needs to be.

    I'm building a KVision+Micronaut project on Linux and running into an error during my Gradle build, starting with no gradle cache:

    If I try to run in a second time, I get nearly the exact same error except it says "Permission denied" instead of "not found". That error then continues.

    Here are some potentially relevant portions of my gradle file, which are copied from various kvision samples:

  • Spring Boot OAuth2

    Spring Boot OAuth2

    First of all I would like to say that this project seems very promising and can be used by our company's internal tools team.

    Thank you for your hard work on integrations and documentation.

    We use OAuth2 (Keycloak) in our company for authentication. I tried template-fullstack-spring-boot example and added simple oauth security configuration:

    1. implementation("org.springframework.boot:spring-boot-starter-oauth2-client")
    2. simple application.yml Github configuration:
                clientId: client_id
                clientSecret: client_secret
    fun securityWebFilterChain(http: ServerHttpSecurity): SecurityWebFilterChain {
            return http

    But after I launch app I am getting: jquery.js?0110:10099 GET http://localhost:3000/login 404 (Not Found)

    Should I somehow provide implementation for /login on UI? What is a correct way to handle such situation?

  • Typeahead/Select component with remote data source

    Typeahead/Select component with remote data source

    I am trying to use these components with remote data source but I do not understand how to configure. I think it is better to create a parameter like that:

    suspend fun getOptions(search?: String): List<String>

    It is more customizable and I can use that with the base component (~remote~).

    I have seen the ajax options for the base component, I mean AjaxOptions class, but to separate the UI components from the business logic, I prefer to use a custom service class.

    On the other hand, I have not been seeing a function parameter to display each option of the components. I mean I want to include images and more information like a description or a date. Currently, I can only see a list of items.

  • smooth transitions between switching components

    smooth transitions between switching components

    I'm creating one of my first websites to display data.

    You can see the WIP page here.

    Click the numbers on the left and use ctrl + the up and down arrow keys to naviage.

    I'm wondering if there is a way to switch these images without the screen flickering and irritating people's eyes.

    This may be due to a lack of experience on my part, or it may be an inherent limitation of kvision. Probably the former and if so I apologize but I wasn't sure where else to ask this.

    When you switch between subjects, this code is eventually called to make the change:

    (this is called within a VPanel that's inside the tab)

    //  inspectChildrenRetrieval constructs all the components and returns a List<Widget>
    // I was hoping this would reduce the flickering by preloading and preparing the images
    val hopefullyPrepped = inspectChildrenRetrieval(obj)
    // removes all children from the VPanel. 
    // I see at the bottom of this, the function refresh() is called. 
    // Perhaps this is bad for my situation? 
    // Is there some way to avoid the refresh() here to reduce visual flicker?
    // obviously the main flicker happens here, when everything is added. 
    // The images seem to appear at the wrong size and then quickly fix themselves. 
    // How can I make them appear at the right size and location right away?

  • Page loader module

    Page loader module

    I think one of the things missing for KVision is a good loader/spinner module. Since a lot of the cool things KVision can do are using coroutines and ajax requests, it stands to reason that KVision needs a good loading bar.

    I saw there is ProgressBar which works well for our team in our forms, but we also would like a generic loader when we load our data from the backend (our app is very data intensive and makes a lot of requests).

    I could just create something for our team, but would rather contribute something to KVision for others. Let me know what you think, I was thinking something like a wrapper for nanobar.js or pace.js

  • Support for global styles without relying on css classname literals

    Support for global styles without relying on css classname literals

    One way to avoid recalculating styles on the fly (and yet keep styling in code) is to have a global styles class (or series of classes/objects) which is initialized.

    For example:

    class GlobalStyles {
        val cardStyle = Style(".card") {
                // stuff here

    This gets "imported" as follows:

    val styles = GlobalStyles()

    ...and now styles don't need to be regenerated each time components are rerendered. However, it's a bit messy, since it relies on the css classname to "link" the style to the component; i.e. to use it, of course, I have to have a widget that does:

    class CardView(): Div() {
       init {

    I can't even break out "card" fully to a constant, because the css rule wants a dot in front of it, so I'd need to prepend with a dot when initializing the style (which is...ok, but still smelly.)

    Can you come up with a cleaner way of "linking" the component to the global style? (This may be the same solution as #450, but I thought I would file separately in case there are two separate ways of tackling this.)

    One possibility, though I don't know if inline/reifying/etc will work with the js compiler:

    class GlobalStyles {
        val cardStyle = Style.for<CardView>() {
            // stuff here

    Of course, people would eventually want to replicate CSS selectors in code, so you could imagine craziness like:

    class GlobalStyles {
        val cardStyle = Style.for<Heading1>().in<CardView> {
            // stuff here

    ...but maybe this isn't so bad, as it's more readable than css selectors for somebody who isn't a browser developer.

    Another simpler possibility:

    class CardView {
        staticStyle {
             // stuff here

  • New map module based on MapLibre

    New map module based on MapLibre

    This is a very speculative issue,


    I like the look of MapLibre for a couple of reasons:

    • TypeScript native (Leaflet is entirely JS and it doesn't look like they'll be using TypeScript any time soon)
    • Native vector tile support https://maplibre.org/maplibre-gl-js-docs/example/third-party/ (Leaflet requires 3rd party plugins)
    • Leaflet has an ugly display bug (for 7 years!) where white lines appear between tiles https://github.com/Leaflet/Leaflet/issues/3575
    • it uses TypeScript, which is much more easy to integrate with Kotlin

    Generally it looks like MapLibre is less popular (it's much newer, having been recently split from MapBox, after a license change), but it supports more modern features.

    Implementing MapLibre bindings is made much more difficult because Dukat fails to generate anything https://github.com/Kotlin/dukat/issues/477. By comparison, Dukat did generate most of the Leaflet bindings, which provided a good basis. However... those aren't perfect because Leaflet is not TypeScript native (unlike MapLibre), so the TypeScript the Leaflet bindings were generated from might not be accurate (but they seem to work okay). So it's a mixed bag. Anyway, defining new bindings is a lot of work, regardless of Dukat support.

    There is some interest in creating Kotlin bindings for MapBox/MapLibre https://github.com/Kotlin/dukat/issues/477. Additional it looks like there's some movement to migrate the MapLibre's Java code to Kotlin https://github.com/maplibre/maplibre-gl-native/pull/420 - so maybe MapLibre devs could help with the bindings? Or even include them themselves? I might make an issue.

    I'm not likely to pick this up any time soon - Leaflet is good enough. But if there's a lot of support, or someone wants to collaborate, I could give it a go.
