Hi.. I want to use mutex.withLock{...} but it requires ‘suspend’ keyword which is a breaking change, how can I achieve the same effect (like synchronized in java) without leaking/changing my fun def? (KMP btw)

[Robert Wijas]

wrap with runBlocking maybe?

[why]

runBlocking in undefined in commonMain (KMP)

[Robert Wijas]

do you support JS?

[why]

yes I do, but it’s just there because I can :D

[why]

about runBlocking : https://kotlin.github.io/kotlinx.coroutines/kotlinx-coroutines-core/kotlinx.coroutines/run-blocking.html

[Robert Wijas]

I guess you need to either change your API or implement a runblocking equivalent for JS. But I’m a Kotlin newbie, so if there’s a different solution I’d love to know as well 🙂

[why]

Thanks for you input, if I find anything else i’ll let you know :D

[why]

Ok so I found a solution, I used SynchronizedObject/ReentrantLock from kotlinx.atomicfu library :D
