These are my build settings
lazy val shared = commonSettings ++ Seq(

The requests my front/index page is making are:

I'm wondering where I've made the mistake.
import java.nio.file.{Files, StandardCopyOption}
import com.typesafe.sbt.packager.SettingsHelper._
lazy val server = project
.in(file("server"))
.settings(BuildSettings.server)
.settings(
scalaJSProjects := Seq(client),
(Compile / resourceGenerators) += Def.task {
val webpackFiles = (client / Compile / fullOptJS / webpack).value.map(_.data).filterNot(_.getName contains "bundle")
val npmFiles = Seq.empty[File]
(webpackFiles ++ npmFiles).map { sourceFile =>
val targetFile = (Compile / resourceManaged).value / "public" / sourceFile.getName
Files.createDirectories(targetFile.getParentFile().toPath())
Files.copy(sourceFile.toPath, targetFile.toPath, StandardCopyOption.REPLACE_EXISTING, StandardCopyOption.COPY_ATTRIBUTES)
targetFile
}
}.taskValue,
)
.enablePlugins(WebScalaJSBundlerPlugin, SbtTwirl, JavaAppPackaging)
.aggregate(client)
.dependsOn(sharedJVM)
its still work in progress (I guess I might need to copy some npm files too), but it's a start
show compile:managedResources
[info] client / Compile / managedResources

Hey, I'm trying to follow along the instructions, but I can't get the continuous compile to work. I ran the project using both
~run and ~reStart but if I change the SharedMessages.itWorks content, and refresh the page, it doesn't show the update message unless I ctrl + c and re-run it.
i've noticed that an old version is still running on localhost:8000 and i had to increment the port to 8001 to get it to bind the port
Does it auto reload / recompile for you if you make changes and use ~reStart ?
When using
~reStart and changing SharedMessages.scala, I can see in the SBT output that it's calling fastoptjs (Fast optimizing ...). However, I don't see the Scala.js message being updated in Chrome when I reload the page. I do see the change when I open a private window, so it's probably a caching issue.
Hi, I have a problem that tests doesn’t work in the client project.
Could you please help me ?

Hi, it looks like you need to use triple %, so that scalatest and scalacheck can be used from Scala.js. You will also need to use Scala.js 0.6.x instead of Scala.js 1.x because scalatest & scalacheck are not compatible with Scala.js 1.x yet. So, update your build.sbt to have:
"org.scalatest" %%% "scalatest" % "3.0.5" % Test,
"org.scalacheck" %%% "scalacheck" % "1.14.0" % Testand update your project/plugins.sbt to use:
addSbtPlugin("com.vmunier" % "sbt-web-scalajs" % "1.0.8-0.6")
addSbtPlugin("org.scala-js" % "sbt-scalajs" % "0.6.23")You should then be able to run your client's tests.
I think I need it to run the command
fastOptJS/webpack
Error: 8080 Address already in use
@joan38 Hey, have a look at https://scalacenter.github.io/scalajs-bundler/reference.html#webscalajsbundlerplugin to use scalajs-bundler and https://github.com/scalacenter/scalajs-bundler/tree/master/sbt-web-scalajs-bundler/src/sbt-test/sbt-web-scalajs-bundler/play for a project example
@michael_zh_twitter it looks like you already have a process listening on port 8080
The best I can come up with is to create a new stage that moves the files.
sbt-web-scalajs does not have any settings to configure the target directory. It relies on sbt-web, which takes care of copying the pipeline output files. If using Play, I think sbt-web's target directory can be changed by setting
WebKeys.public in Assets := file("<folder-path>") in the server project
I'm trying to build a ScalaJS project with Scala 3. If I run my project with scala 2.13 it works fine, but if I change the version to 3.0.0-M3 it fails with bad option: -P:scalajs:mapSourceURI:...
The issue persists even with the bare minimum configuration:
lazy val client = (project in file("client"))
.settings(commonSettings)
.settings(
scalaVersion := "3.0.0-M3",
scalaJSUseMainModuleInitializer := true
)
.enablePlugins(ScalaJSPlugin, ScalaJSWeb)and plugins:
addSbtPlugin("ch.epfl.lamp" % "sbt-dotty" % "0.5.1")
addSbtPlugin("org.scala-js" % "sbt-scalajs" % "1.3.1")
addSbtPlugin("com.vmunier" % "sbt-web-scalajs" % "1.1.0")Any clue how to resolve this issue?

Hey everyone, sbt-web-scalajs v1.2.0 is now available! It's compatible with Scala 3 and updated to Scala.js 1.5.1 https://github.com/vmunier/sbt-web-scalajs/releases/tag/v1.2.0
@tzbob or @ngbinh you both historically had this ... IntelliJ recompiles the whole project in order to do an sbt import problem ... (I've memorialized it here: vmunier/sbt-web-scalajs#169) ... did you ever find a solution?
