scala.js

I would like to use scala-js with sbt-web in such a way that it can be compiled to produce javascript assets that are added to the asset pipeline (e.g. gzip, digest). I am aware of lihaoyi's workbench project but I do not believe this affects the asset pipeline. How can these two projects be integrated as an sbt-web plugin? Scala-js produces js files from Scala files. The sbt-web documentation calls this a Source file task . The result would look something like this: val compileWithScalaJs = taskKey[Seq[File]]("Compiles with Scala js") compileWithScalaJs := { // call the correct compilation

I'm new to Scala.js. I'd like to use the Argonaut json library. https://github.com/argonaut-io/argonaut Its only dependencies appear to be Monocle and Scalaz which both have versions compiled for Scala.js. I'd be happy to work on porting Argonaut to Scala.js, but don't have a firm idea on how to begin. Does anyone have any pointers? Thanks. sjrd Quick proof-of-concept The first thing to try is to convert the build so that the JVM projects become Scala.js projects. The basis for this is pretty easy: In project/plugins.sbt , add the dependency to the Scala.js sbt plugin: addSbtPlugin("org.scala

I'm working on a Scala.js cross project where the jvm folder represents my server application and js represents my scala.js code. Whenever i compile my scala.js code via sbt crossJS/fastOptJS the compiled JS ends up in ./js/target/scala-2.11/web-fastopt.js . I need to have this compiled JS file accessible in the resources of the server project in the jvm folder, so i can server it through my web application. I think i have to do something with artifactPath but i can't seem to get any results from my experiments thus far. You can simply set the artifactPath of the fastOptJS task (or the

There are two tools to compile Scala code right in the JavaScript: Scala.js and JScala . Both of them look great, and can work with non-trivial Scala code. What is the technical difference between them? Actually there are more than two tools, but Scala.js and JScala are indeed the 2 tools still under active development. The difference is fundamental: Scala.js is a compiler from Scala to JavaScript, whereas JScala is a macro-based DSL for generating snippets of JavaScript code. As @Gaurav explained in his answer, Scala.js is the regular Scala compiler, but it emits JavaScript code instead of

Has someone used Scala-JS in real web project but not only for plain JavaScript replacement in isolated env ? I would like to use Scala as much as possible (I wish I could). And seems Scala-JS claims to be that lib I could use (now) or in the future. That's why I'm interested in small working solution to look at, to bootstrap (like PlayFramework app where Scala-JS ). The solution/example that could demonstrate that Scala-JS can be used in real web-development work. I'm asking because what I found about Scala-JS so far is hardly real usage of it. Q: some examples / proves that It is ready to

Let's say I have a map.csv file at the same level (or some other webapp-accessible place) as index-{dev,opt}.html , e.g.: key1,value1 key2,value2 ... keyN,valueN I want to read in that CSV file and end up with a Map[String,String] . I know how to do that in Scala, but how would I do that in Scala.js? I'm trying not to hard-code the keys and values. The parsing is basically identical to how you would do it in conventional Scala -- it's the same language, after all. So the real issue is fetching the file. There's no one-size-fits-all solution there; it depends on what you're using as the web
