When I build an MPP project for JS browser(IR) target, the Webpack task copies the .js and .js.map files to the distribution directory, but not the .d.ts file. Is there a way to get that file included too?

It doesn't? I could swear it does. What kind of binary do you have registered?

[grahamborland]

js(IR) {
        browser {
            commonWebpackConfig {
                cssSupport.enabled = true
            }

            distribution {
            }
            webpackTask {
                outputFileName = "sliktest.js"
            }
        }

        binaries.executable()
        useCommonJs()
    }

And that's you issue. You're not really building an executable if you need .d.ts files. Change it to binaries.library()

[grahamborland]

Ah, thanks.

[Big Chungus]

You might find npm-publish useful for packaging and distributing.

[grahamborland]

binaries.library() causes Gradle sync to fail in the IDE with a weird internal intellij stacktrace, but at least on the command line it does now include the d.ts in the distribution. Thanks for the help. 🙂

[Big Chungus]

Yeah, binaries.library() did not receive as much love as binaries.executable() yet.

If you do use that plugin, just running ./gradlew packJsNpmpublication should produce all you need to distribute your lib in build/publications/npm/js

[Big Chungus]

You can also publish them via the plugin to npm repository, but the most common use-case I've found is to pack kotlin.js lib into tarball and then install it into a JS/TS project from that (assuming both projects live in the same monorepo)

e.g.

pwd # IdeaProjects/my-project/kotlin-lib
./gradlew pack
cd ../ts-app
pwd # IdeaProjects/my-project/ts-app
yarn install ../kotlin-lib/build/publications/npm/js-1.0.0.tar.gz

[Big Chungus]

But you can do all that without a plugin as well, just a bit more work
