One of the compilation targets of Kotlin Multiplatform is JavaScript. It’s pretty awesome that I can take the same Kotlin code and tools I write Android with, and write code that runs in a browser (or in Node.js).

Here is the video I’ve created to walk you through the creation of a Kotlin Multiplatform Project using the templates in Intellij IDEA, and what you can do to get your Kotlin running as JavaScript in the Browser!

Here are the code snippets mentioned in the video:

./gradlew build

 js(LEGACY) {
     browser {
         webpackTask {
             output.libraryTarget = "this" // Will add to window
         }
         binaries.executable()
     }
 }

 fun printHi() {
     println("Hello World Sam!")
 }
 fun main(args: Array) {
     printHi()
 }

 helloworldsam.printHi()
