An example application written in ScalaJS using scala-js-dom and scala-js-workbench
This is a slightly less barebone example of an application written in Scala.js. In particular, it links in libraries that are indispensible in being productive working with Scala.js.
To get started, run
localhost:12345/target/scala-2.11/classes/index-dev.htmlin your browser, it will show you an animated Sierpinski triangle (live demo). You can then edit the application and see the updates be sent live to the browser without needing to refresh the page.
sbt fullOptJSand open up
index-opt.htmlfor an optimized (~200kb) version of the final application, useful for final publication.
Take a look at the
dodge-the-dotsbranch in the git repository if you want to see a slightly more complex application that was made in 30 minutes using this skeleton. Similar steps can be used for development or publication. There's a live demo here.
There's also a
space-invadersbranch, also made in 30 minutes, with its own live demo.
todomvcbranch contains an implementation of the TodoMVC example application, which is used to compare how the exact same application would be implemented using different languages and frameworks. This application makes heavy use of Scalatags and Scala.Rx, with heavy use of the DOM via scala-js-dom, making it a good example of how reactive web pages could be built using ScalaJS, as well as use of standalone ScalaJS libraries. live demo
ray-tracerbranch contains a simple ray-tracer written using Scala.js, with a live demo.
mapperbranch contains an application that renders a heat map of the earth, using data pulled from OpenWeatherMap, with a live demo
autowirebranch contains a small sample client-server application, using Scala.js on the client and Spray on the server. The readme on that branch contains instructions on how to run it.
