We also have a standalone distribution that doesn't require SBT.
Important notice! Scala.js is still experimental! Although this is a project of LAMP/EPFL for which we will continue to provide best-effort improvements and bug fixes, it is not supported by Typesafe, and not part of any of their support contracts. You have been warned!
- Support all of Scala (including macros!), modulo a few semantic differences
- Integrated with sbt (including support for dependency management and incremental compilation)
- Can be used with your favorite IDE for Scala
- Generates Source Maps for a smooth debugging experience (step through your Scala code from within your browser supporting source maps)
- Integrates Google Closure Compiler for producing minimal code for production. Compiled blobs range from 170-400kb
- Official mailing list
- Scala.js tag on Stackoverflow. Please help building it up by asking questions.

This is a collection of libraries that work with Scala.js. Some of them, like
scala-async are pure-macro projects, and thus work with Scala.js out of the box. Most of them, though, started off as Scala-JVM projects and were ported over, and thus have separate artifacts to run on each platforms. The SBT snippets given are for the version that runs on Scala.js.

Scala-Async is a pure-macro project without any runtime dependencies. Thus it works with Scala.js out of the box, without needing to be specially compiled for it.
Another pure-macro project, Scalaxy loops and streams work great with Scala.js without needing to be specially compiled for it.
