Hi. When developing a Kotlin Multiplatform library...

# javascript

Hi.
When developing a Kotlin Multiplatform library for browser usage using the new IR compiler (i.e. js(IR) {...}), what is the way to obtain all required files to publish the library on NPM, namely:
• How is the libraries package.json created?
• Is the kotlin standard library and kotlinx libraries (e.g. coroutines) bundled in the library or referenced from the created package.json?

[Big Chungus]

#npm-publish should address most of this if not all

[Big Chungus]

As for klib bundling part of the question, they're compiled down to js and included in your js lib bundle

Thanks.
Isn't there a way to accomplish the goal without using the npm-publish plugin, i.e., just using the kotlin Multiplatform plugin?

[Big Chungus]

Sure, you can do what npm publish does manually. i.e. collect all relevant files plus package.json into a folder and then run npm executable with appropriate args and flags via gradle's custom Exec task

[Big Chungus]

You can either assume npm executable being present on the system path or use one that kmp plugin fetches

Thanks. Is the folder <root>/build/js/packages/<project-name> a good starting point? It already contains a package.json.

[Big Chungus]

Not quite, that one has intermediate js output that's not yet suitable for publishing

[Big Chungus]

I don't recall the correct dirs now, but you can just have a look at which directories the plugin collects and how it builds the package.json file

[Felix]

Will do. Thanks!
