Hello, if I’ve been building a Kotlin Multiplatform Mobile library up until now, and I decide to start adding JS support, is it as simple as adding js() target in the Kotlin block of the build file? Or will there be complications since I started with the KMM template instead of the KMP template?

Should be as simple as adding js() target and implementing your actual declarations there

[David Herman]

One issue I recall running into adding js to a project was I had made some threading assumptions in my design that didn't work in the single-threaded JS world

[David Herman]

It wasn't a deal breaker, I just needed to step back and think about the API a bit

[Arkadii Ivanov]

If you are using a database, this might be a problem as well in JS.

Also check if your MPP dependencies (if any) support js target. If they're from maven central you can use kamp.petuska.dev to check

[Paul Dhaliwal]

Excellent thanks! We’ve been carful to avoid any libraries that didn’t support JS, as we knew this would be a possibility. So far everything seems to be working correctly by simply adding the js target.

It's really nice to see that currently there are enough multiplatform libraries that scenarios like this actually happen in the real world, it's not just a sales pitch about it being easy
