An initial experimental implementation of kotlinx.coroutines version 1.8.0-RC2-wasm0 for WASI was published into the experimental repo. To be compatible with current 1.9.20 toolchain one have to wrap main function into runEventLoop function call, like:

// main or other "root" function
fun main() = kotlinx.coroutines.runEventLoop {
    GlobalScope.launch { 
        // suspend function call
    }
}

A coroutine test, that uses ``kotlinx.coroutines.test`` can be written as usual, like:

@Test
fun myTest() = kotlinx.coroutines.test.runTest {
    // suspend function call
}

Can you provide some technical details, how did you solve the missing platform apis? Looking at the source code its is a single "thread"/event loop solution using global variables.

[Igor Yakovlev]

Yes. It is single thread event loop. Delayed coroutine uses blocking timer. As far as wasm is single-threaded now this is the only solution we see.
