This project aims at providing a Scala to JavaScript compiler, so that one can write the client-side of a Web application in Scala, and have it compiled into JavaScript code.
Get the code with git. Beware that this repo contains one submodule, which
you need to clone too. To do this, add the --recursive option when cloning.
If you've already cloned this repo, cd into it and do:
$ git submodule init
$ git submodule update
Scala.js uses sbt for its build process. In order to use it locally, you need to publish the compiler, library and sbt plugin locally.
Don't worry, this is super-easy:
sbt> publishLocal
You can compile the example applications with:
sbt> examples/optimizeJS
Then, you can "execute" them by opening their respective HTML files in your favorite browser. Since optimizing the JavaScript takes time (tens of seconds to several minutes, depending on your hardware), it is also possible not to optimize JS by doing instead:
sbt> examples/packageJS
In this case, you have to open the -dev version of the HTML files.
Currently, two examples are provided:
examples/helloworld/helloworld.html, saying Hello World in four different ways (using DOM or jQuery, and using the untyped or typed interface to JavaScript).examples/reversi/reversi.html, an implementation of a Reversi game. Note that it uses the HTML5 Canvas element, so it won't work with Internet Explorer 8 or below.
We provide an example application which you can fork to kick off your own project. Its readme provides further explanations on how to do so.
