Avoid any boilerplate in your project by using just one annotation to export your Golem worker from Scala to JS.
Add sbt-wasm-component as a dependency in project/plugins.sbt:
addSbtPlugin("io.github.danieletorelli" % "sbt-wasm-component" % "x.y.z")The WASM component plugin is automatically loaded, it just needs to be enabled with enablePlugins(WasmComponentPlugin) in your build.sbt:
ThisBuild / version := "0.1.0-SNAPSHOT"
ThisBuild / scalaVersion := "2.13.13"
lazy val root = (project in file("."))
.enablePlugins(WasmComponentPlugin)
.settings(wasmComponentPackageName := "example")Then you will be able to annotate your Golem worker object with the @cloud.golem.WitExport annotation:
package example
@cloud.golem.WitExport
object ShoppingCart { self =>
def initializeCart(userId: String): String = {
println(s"Initializing cart for user $userId")
if (math.random() > 0.1) userId
else "Error while initializing cart"
}
// ...
}
Once done that, it will be enough to run sbt wasmComponent and the plugin will take care of exporting your worker in WASM.
