I know there is no reflection support to js and native, but is there any way to implement dynamic proxy? I want to create something like https://github.com/square/retrofit for common code (Android+iOS)

On the Java side you can use the normal JDK proxy system. On the JS side you can look at how Kotlin objects are constructed and then just use native Javascript code (

js

function) to create those dynamically.

Native is the most challenging part actually. @olonho maybe you can help here?

not sure if this is something that could be properly implemented with native. What exactly do you want it to do? Can you write same/similar code in C?

feels free to post your github repo if you would like to open source it. Im interested in an retrofit api interface compatible rest client for kotlin native and kotlin/js. Need the same and would also implement it.

Plain C is not possible I think. Simple explanation of retrofit internals could be found here: https://medium.com/@jintin/retrofit-2-b0c80d5caadf

and annotation processor support for kotlin native is also not planned?

The way that I'm doing it now is with an expect interface in common, an actual interface in JVM with the Retrofit annotations, and then an actual interface and implementation in JS with manual calls to

fetch

right, most things achieved with reflection on dynamic runtimes ae better be done with the compiler plugins on Native

@olonho any eta/plans for native plugin api?

Well, some unstable form is already here, kotlinx.serialization plugin is written this way
