Maybe this is a dumb question, but what's the easiest way to get the equivalent of Kotlin/JVM's readLine() in Kotlin/JS (nodejs target)?

[Vampire]

I guess using readline module from node.js, targeting process.stdin?

[jeff]

I tried that, but I'm also very new to Kotlin/JS and node. I'm doing this:

implementation(npm("readline", "17.4.0"))

but getting this:

Couldn't find any versions for "readline" that matches "17.4.0"

[jeff]

maybe readline isn't a "module" in the sense of dependency? In which case I need to pull it in differently?

[Vampire]

Nah, that would install a package named readline from npm which is only available in version 1.3.0 and renamed due to the node.js included module called readline.

[jeff]

Got it -- So do I need this syntax?

import * as readline from 'node:readline';

[jeff]

and if so, where do I put that in Kotlin?

[Vampire]

You want org.jetbrains.kotlinx:kotlinx-nodejs as normal dependency if you don't have it yet.
And then you can just do import readline and use it iirc

[jeff]

Awesome I will try that. Thanks for your help!

Or if you are on Kotlin 1.6, just use readln that is fully cross-platform: https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.io/readln.html

[jeff]

Sadly:

Currently this function is not supported in Kotlin/JS and throws UnsupportedOperationException.

😕

[Vampire]

Hm, why is it marked as supported then at all? o_O
