Question

Hey just in case I was able to link native library to WASM JS in scope of <https kotlinlang slack com archives C0BJ0GTE2 p1677748948814649> There a lot of hacks of course but still it works For now only on nodejs but I will try to add browser wasi there also Thanks for working on WASM and on `wasm` support in `skiko` which helped me a lot slightly smiling face Is there any plans for allowing to somehow distribute or easier link to external `wasm` binaries

sdeleuze · Answer

IMO easy distribution and linking of Wasm files should happen middle term via Wasm Component Model and warg repositories Higher performance cinterrop style should be possible for specific needs but will be IMO more involved

Oleg Yukhnevich · Answer

Overall yes but what if someone will want to use some internal native library like in skiko There is no reason to publish it somewhere else but just embed somehow into kotlin library published to maven central

sdeleuze · Answer

I guess some cinterop style tooling working for Kotlin Wasm would make sense for this kind of use case

sdeleuze · Answer

Mainly to avoid copying memory too much

sdeleuze · Answer

But for dynamic linking of Wasm files IMO Wasm Component Model is the way to go for a wide range of reasons

sdeleuze · Answer

I will have a deeper look to what you did thanks for sharing BTW

Oleg Yukhnevich · Answer

I agree that component model is just perfect and will help a lot we just not here yet so I ve done what is possible right now with current K WASM slightly smiling face

sdeleuze · Answer

Yep thanks for that slightly smiling face

sdeleuze · Answer

I was planning to experiment on leveraging Rust and C libraries without Component Model next week so your work arrive at a perfect timing

sdeleuze · Answer

I will share feedback

gt I was able to link native library to WASM JS Awesome gt Is there any plans for allowing to somehow distribute or easier link to external `wasm` binaries We want to improve this area but we don t have a concrete design yet Feel free to report an issue to YouTrack with your use case

Oleg Yukhnevich · Answer

Okay I have several `Questions` in repository readme I will convert them to YouTrack issues in coming days slightly smiling face

Matt Nelson · Answer

Just quickly looking at your lib You are using `Random` which is not providing cryptographically secure random numbers which anything built atop of will be borked cry See <https github com 05nelsonm secure random>

Oleg Yukhnevich · Answer

as far as I remember there is no usage of any `Random` at all in `ffi kotlin` slightly smiling face On the other side secure random is provided in <https github com whyoleg cryptography kotlin> but it s another library

Matt Nelson · Answer

Ah I see what you re doing there
