Copy code
w: The version of the Kotlin/Wasm standard library (2.2.20-Beta2-release-177) differs from the version of the compiler (2.2.0). Please, note that while Kotlin/Wasm is in active development phase only matching versions are supported.
Please, make sure that the standard library has the same version as the compiler. Adjust your project's settings if necessary.
e: warnings found and -Werror specifiedj

jw
08/01/2025, 4:28 PMSeems like it allowed the commonization of the js and wasmJs code

08/01/2025, 4:31 PMThe documentation was added at the same time as the requirement which was after I started using it 🙃
I guess they do mention that
Note that the library is experimental, and the API is subject to change.but I didn't expect that to mean requiring pre-release versions.

@jw do you mean own browser declarations?

08/01/2025, 5:20 PMMultiplatform kotlin-browser is already here
turansky
08/01/2025, 5:20 PMWe use stable Kotlin only
turansky
08/01/2025, 5:34 PMWe cover 100% of stable browser API.
Or you need something else?

jw
08/01/2025, 5:38 PMI mostly just don't want the added dependency
jw
08/01/2025, 5:38 PMLike you said, the APIs are stable so you spend 5 minutes writing your own and then you're done forever

08/01/2025, 6:01 PMWhat's the difference between them (other than stability)?1. More declarations 2. More strictness (method parameters, event types) 3. Safe JSO factories (JS platform only) 4.
