Installation

Requirements

• Scala 3.x (tested with 3.8.3)
• Scala.js 1.x (tested with 1.21.0)
• Node.js (runtime)
• sbt (build tool)

Add the Dependency

Add Apion to your build.sbt:

libraryDependencies += "io.github.edadma" %%% "apion" % "0.1.0"

SBT Project Setup

A minimal build.sbt for a Scala.js project using Apion:

ThisBuild / scalaVersion := "3.8.3"

enablePlugins(ScalaJSPlugin)

scalaJSLinkerConfig ~= { _.withModuleKind(ModuleKind.CommonJSModule) }

libraryDependencies += "io.github.edadma" %%% "apion" % "0.1.0"

Also add the sbt-scalajs plugin in project/plugins.sbt:

addSbtPlugin("org.scala-js" % "sbt-scalajs" % "1.21.0")

Build & Run

# Compile and link
sbt fastLinkJS

# Run with Node.js
node target/scala-3.8.3/project-fastopt/main.js

For development with auto-restart, you can use nodemon:

npx nodemon --watch target -e js --exec "node target/scala-3.8.3/project-fastopt/main.js"
