Scala.js Tutorial 🔗

Create a deder.pkl file in your project root:

amends "https://sake92.github.io/deder/config/DederProject.pkl"

local const frontend: ScalaJsModule = new {
  id = "frontend"
  scalaVersion = "3.7.1"
  scalaJsVersion = "1.20.2"
  moduleKind = "es-module"
  deps {
    "org.scala-js::scalajs-dom::2.2.0"
  }
}

modules {
  frontend
}

Run in watch mode:

deder exec -m frontend -t fastLinkJs -w

The output will be in .deder/out/frontend/fastLinkJs/main.js.
You can include this in an HTML page to run your Scala.js code in the browser.
