Asking in because I didn t get a res

Question

Asking in < C0B8L3U69|javascript> because I didn t get a response in < C3PQML5NU|multiplatform> Does anyone have an example of a multiplatform JVM amp Javascript project that uses the W3C DOM API I m not sure how to define the `expect` declarations because the DOM API is mapped to interfaces in the JVM platform and classes in the Javascript platform The DOM objects are provided by factories in both platforms so my code only needs to use the DOM objects not instantiate the classes nor implement the interfaces What should the expect declaration be

turansky · Answer

Which DOM class you want to use as alias

turansky · Answer

Definetely works following example ``` common expect class Color JS Suppress ACTUAL WITHOUT EXPECT actual typealias Color = csstype Color ``` `csstype Color` <https github com JetBrains kotlin wrappers blob f37444bfaf705a1270fcc03eec0c15ca2b8f814f kotlin csstype src jsMain generated csstype Color kt L12|external interface>

And what would the declaration be for the JVM platform

natpryce · Answer

I want to use the W3C XML DOM APIs in the org w3c package Node Element Attr etc

natpryce · Answer

For example on the JVM platform Element is declared as `public interface Element extends Node` while on the JS platform it is declared as `public abstract external class Element`

natpryce · Answer

On both platforms the types are declared in org w3c dom so I want to write my code that uses the DOM in the common module and declare an `expect` function that loads a document implemented by platform specific `actual` code in the JVM and JS modules

natpryce · Answer

But I ve not been able to work out how to declare that

turansky · Answer

Common = Like in JVM JS with `Suppress`

natpryce · Answer

So the common module would have to declare `expect`s for all the types in the org w3c package

natpryce · Answer

I was hoping to avoid that because both platforms already have the org w3c package

Looks like it can be generated slightly smiling face

natpryce · Answer

Yes that s looking like the best approach

Thanks

FYI latest Browser declarations you can find <https github com JetBrains kotlin wrappers tree master kotlin browser src jsMain kotlin web|here>

turansky · Answer

What is the final goal If it s not a secret

natpryce · Answer

I have a library for fuzz testing various structured data formats and encodings It is compiled to JVM amp JS with a Makefile and the command line Kotlin compiler The multi platform build uses a directory of cross platform code and directories of platform specific code and each platform build compiles all the cross platform code and platform specific code as a single compilation unit It works very well and thanks to Make builds much faster than Gradle However there is so little support for the command line tools that upgrading to 1 8 and the new IR is very difficult So if I can get a low maintenance project structure working with kotlin multiplatform I ll bite the bullet and move to Gradle

I expect desynchronization between JVM and JS implementations How you will calculate common part between JVM and JS
