How to export general case class properties

Question

I am trying to split the case class between server and client. I use upickle on both ends. Objects and their data are well accessible at both ends.

general class

case class Foo(var id : Long,var title: Description) 

However, I need to export the case class fields on the client side. I could add the @ExportAll annotation, but that means pulling scalajs libraries into the server project.

Maybe the best way to expose the id and title of javascript members.

The right way to export things to JavaScript is to use the @JSExportAll annotation. However, you cannot and should not pull the Scala.js libraries into the server project. For this use case, we have a dedicated JVM artifact, scalajs-stubs , which you can add to your JVM project as follows:

 libraryDependencies += "org.scala-js" %% "scalajs-stubs" % scalaJSVersion % "provided" 

As a “provided” dependency, it will not be present at run time. But this will allow you to compile the JVM project, even if it references JSExportAll .
