I'm developing Kotlin/JS Project and I have created new sourceSets but by default makes the type = Multiplataform. How can change KotlinPlatformType in gradle?

Gradle code:

val backend by creating{}
val webapp  by creating{}

[Ilya Goncharov [JB]]

Do you apply org.jetbrains.kotlin.multiplatform plugin?

[frank]

@Ilya Goncharov [JB]
not, I applied Kotlin/JS plugin.

Gradle Code:

plugins {
    kotlin("js") version "1.4-M1"
}
repositories {
    maven("<https://dl.bintray.com/kotlin/kotlin-eap>")
    jcenter()
    mavenCentral()
}

kotlin {
  sourceSets {
        val commonMain by creating {
          dependencies {
                implementation(kotlin("stdlib-js"))
            }
        }
		
		val backend by creating{
            group = "org.example"
            version = "1.0.0"
            target {
                nodejs()
                produceExecutable()
            }
			
            dependencies {
                implementation(kotlin("stdlib-js"))
            }
        }

        val webapp by creating{
            group = "org.example"
            version = "1.0.0"

            target {
                browser()
                produceExecutable()
            }
            dependencies {
                implementation(kotlin("stdlib-js"))
                implementation("org.jetbrains.kotlinx:kotlinx-html-js:$html_version")
                implementation("io.socket:socket.io-client:1.0.0"){
                    exclude("or.json","json") // excluding org.json which is provided by Android
                }
            }
	    }
    }
}

Thank you, I see
Seems that some problems with IDEA import from Kotlin side. Seems that it should not affect build. Do you faced with some red code or build problem?
Btw

target {
   ...
}

is code, which configure per module, it is for configure full JS target, not only one source set.
Honestly, for now we don’t fully support multiple source sets.
For your case, I think you can use multi module Gradle build.

- root
 - common Kotlin/JS module
 - backend Kotlin/JS module
 - webapp Kotlin/JS module

And use dependencies like this

backend

dependencies {
     implementation(project("common"))
}

@Ilya Goncharov [JB],
I found this project structure in a Jetbrains Kotlin/MPP sample project. I liked because the code was in the same folder. (src\<target>\kotlin).

Do you faced with some red code or build problem?
when I run build task I have 2 problems:
1 - ':compileKotlinJs' task going to search kotlin classes to 'main' no other sourceSets(backed etc...).
2- :browserProductionWebpack task not found other JS libraries.

I think than having multiples sourceSets gives me this problems.

With Kotlin MPP, Can i configure multiples JS Projects by sourceSets?

Jetbrains planning to increase support for multiple sourceSets?

Yes, I think you need so called HMPP in 1.4 release, but for now it is in experimenting mode for mobile multiplatform

You need to declare tasks for your source sets manually, so it will be very inconvenient. I am making refactorings time by time to make it easier to work with multiple source sets. But for now it is not this time unfortunately. ANd in fact tasks will be added for main and test source sets.
Could you please link me to this Kotlin/MPP sample project?

@Ilya Goncharov [JB], Do you have more info about Hierarchical Multiplatform Projects for follow it?

Jetbrains Kotlin MPP sample:

[Ilya Goncharov [JB]]

Thank you!
In sample, you can get predefined source sets commonMain and jsMain to declare dependencies
(And you send one link twice, but I understand, what you mean)
And with these source sets everything will work, but commonMain is place for common non platfrom-specific code.

About HMPP there will be articles, but for now I am not sure :(

@Ilya Goncharov [JB],
Jetbrains plan to replace multi-module projects by HMPP in kotlin?

[Ilya Goncharov [JB]]

No, they can live together

[frank]

@Ilya Goncharov [JB],
Advantages and disadvantages or limitations?

I suppose that in the future there will be some article that explains it.
