So it looks like Kotlin/JS IR doesn't do DCE when we call binaries.library() - is this on the horizon?

[turansky]

It looks like expected behaviour

🤔 probably cause DCE can't determine which things I actually want to keep around? I noticed when I used mutableMapOf it blew up my payload size substantially - so perhaps the right thing to do is use an npm package that does what I need

[Jim]

I guess I could make a wrapper library that depends and re-exposes mine that does treeshaking

you should probably switch to binaries.executable if you want DCE to remove things you don't use and things you don't want removed, you then have to manually flag with @JsExport

for binaries.library, my guess is that it's expected that an external tool will do DCE
