Routes are generated as numbered strings e.g.

/kv/routeFoo1

,

/kv/routeFoo2

. Does this imply that changing the order of methods in the interface breaks compatibility with existing clients? For both compatibility reasons and clarity of debugging in the network inspector, does it make sense to give routes names based on the target method name:

/kv/routeFooSomeMethod

and/or an annotated name?

Should this

link("/test", url = "/test", dataNavigo = true)

work the same as

routing.navigate("/test")

? Because for me, the former reloads page, while the latter works as expected (uses history api).

I got a bug / race when switching states I have a view that’s bind by

bind(AppManager.store.sub { it.commercialProposalState to it.customerState }) { states ->
  commercialProposalEdit(states.first, states.second)
}

This view is shown only when

state.coreState.view == CP_EDIT

Also this view uses some fields from Then I dispatch an event that changes

state.coreState.view

and sets

state.customerState

fields to null. After that I got an exception that some field from

state.customerState

is null. But view

state.coreState.view

is already changed so my component should not update anymore. It looks like it’s updated first, and only then it is replaced by another view. It seems that this update should not happen, because the component should be disposed before it’s update could be triggered Also this breaks the app and my

commercialProposalEdit

component is never disposed and on every

state

change it throws an exception. So only reloading the page helps.

Hi, after updating to 5.9.0 I started getting error highlighting for all `ServiceException`s and inheritors of

AbstractServiceException

with message

"required Throwable, actual ServiceException"

. Also, references to

Exception

in

io.kvision-kvision-common-remote-commonMain

module are not resolved to anything. The project however compiles file. I use IDEA 2022.2 EAP 222.1198. Is it a problem on IDEA side, or something is not well with kvision module?

I set a tab to closeable but no cross shows up to be able to close it?

I use kvision, but only for the remoting layer. My frontend is currently Compose/Web. However, I do use the KVision project structure with

commonMain

,

frontendMain

, and

backendMain

. This is fine for now, but the next iteration of this will likely have desktop, android and iOS targets as well. I'll want a source set or library that has common code across all the frontends (but not backends, as some of that common code has no JVM platform target e.g. GitLive firebase-auth). Any advice/experience with structuring this kind of project? (More in comments)

Is it possible to bind a Range(Input) to a complex ObservableValue (data class)? Tried also (without success) to bind to a sub-store.

What is the recommended node version at the moment?

Integrating a token-based authorization system with kvision RPCs. I see that this can be done with

requestFilter: (RequestInit.() -> Unit

, however that lambda is non-suspending, which makes integrating with something that might need to do a suspending call to refresh a token unnecessarily difficult, especially with the lack of

runBlocking

on JavaScript. Thoughts on making that suspending to enable this kind of use case?

I’m using an extension for Leaflet maps to implement context menus on overlays. This code works by extending the

Polyline.PolylineOptions

interface and this is causing me some issues. From what I can see from the sources, I also need to create new classes to implement

Polyline

and

Polygon

because both implement the abstract

Path

parameterized by

Polyline.PolylineOptions

. This would be a simple case of copying your code and using the new context-menu enabled options class, but… Is there an alternative? TIA!!

Having trouble upgrading my full-stack build from 5.8.2 to 5.9.0 or 5.10.1... getting gradle build error

Could not resolve io.kvision:kvision-server-ktor:<kvision-version>

. Same build works fine with 5.8.2. Any ideas?

How do I determine the selected

Tab

on a

TabPanel

? I want to persist the `TabPanel`’s state between `bind`s.

Hello all. Can i use kvision with bulma only? Without bootstrap.

I'm trying to bring my KVision site to 'production' and I need to remove the hardcoded websocket URL. I've managed to derive the correct websocket URL from modifying

window.location.href

, but now I need to set up some sort of 'proxy' so I can connect when developing locally I've tried using the dev server option in

build.gradle.kts

// build.gradle.kts
...
          proxy = mutableMapOf(
            "/ws" to mapOf(
              "target" to "<http://localhost:12080>",
              "secure" to false,
              "ws" to true,
              "changeOrigin" to true,
            ),
          ),

but I get an error in the application logs

<i> [webpack-dev-server] [HPM] Upgrading to WebSocket
<e> [webpack-dev-server] [HPM] WebSocket error: Error: read ECONNRESET
<e>     at TCP.onStreamRead (node:internal/stream_base_commons:220:20) {
<e>   errno: -4077,
<e>   code: 'ECONNRESET',
<e>   syscall: 'read'
<e> }

In the browser it tries to connect, but gets an

Invalid frame header

error. I saw that the KVision examples set up websockets proxys, but they look the same as what I have. What else do I need? KVision 5.10.1, Kotlin/JS 1.7.0, more details here

KVision 5.11.0 is out https://github.com/rjaros/kvision/releases/tag/5.11.0

I’m getting this when starting up the frontend:

[webpack-cli] TypeError: cli.isMultipleCompiler is not a function

Any insights?

Yesterdays release of

bootstrap-fileinput 5.5.0

breaks projects using

kvision-bootstap-upload

module. Temporary workaround:

rootProject.plugins.withType<org.jetbrains.kotlin.gradle.targets.js.yarn.YarnPlugin> {
        rootProject.the<org.jetbrains.kotlin.gradle.targets.js.yarn.YarnRootExtension>().apply {
            resolution("bootstrap-fileinput", "5.2.8")
        }
}

Why it's so hard for everyone to keep semantic versioning? ...

KVision 5.12.0 is out https://github.com/rjaros/kvision/releases/tag/5.12.0

KVision 5.13.1 is out. https://github.com/rjaros/kvision/releases/tag/5.13.1

Do we have any pointers on how to run frontend tests with KVision?

Someone has published a video on youtube about KVision! Nice work! 🙂

@Robert Jaros When I use the Tabulator in

dataUpdateOnEdit = true

mode I get a (rather lengthy)

Uncaught exception...

in the browser console which seems to indicate an issue when setting data:

<redacted>....refreshActiveData@http://localhost:8080/web/main.bundle.js:2:1490426\n_setDataActual@http://localhost:8080/web/main.bundle.js:2:1485115\n2995/setData/<@http://localhost:8080/web/main.bundle.js:2:1484530\nsetData@http://localhost:8080/web/main.bundle.js:2:1484442.....<redacted>

The data source for the Tabulator is declared as:

val organizations: ObservableList<OrganizationExch> = observableListOf()

and

OrganizationExch

is declared as

@Serializable
data class OrganizationExch(@Id var extId: String,
                            var name: String,
                            var description: String? = null,
                            var webUrl: String? = null,
                            var imageUrl: String? = null,
                            var theme: String? = null,
                            var createdAt: OffsetDateTime? = null,
                            var updatedAt: OffsetDateTime? = null)

[NOTE: I am trying to edit

webUrl

in my tests] The data originates from a

List

on the KVision back-end (SpringBoot) and I convert it into a

MutableList<OrganizationExch>

before synch (probably unnecessary):

organizations.syncWithList(organizationService.getOrganizations().toMutableList())

I am clearly missing something..... can you help?

Hello, I am building a simple page and I need to open two files for comparing each other. First step, how can I open a file in the browser ????

Hello. Does anyone have an example of using KVision Chart with dynamic data? More specifically with data from a KVision back-end server? I have a use case where charts need to display data dynamically both using filtering components on the front end as well as refreshing with newly updated data from the back end. I've tried using ObservableList for both the DataSet (and underlying

data

) as well as Labels, but, while the Cart paints properly the first time it seems indifferent to updates of the ObservableLists.

I've just got an email about Heroku plans to phase out free services 😞 It means some KVision example apps will no longer be published after November.
