Barebone application written in Scala.js -- not maintained

This repository is not maintained anymore. Consider the scala-js-tutorial repository instead, along with the actual tutorial.

This is a barebone example of an application written in Scala.js.

Get started

To get started, open sbt in this example project, and execute the task fastOptJS. This creates the file target/scala-2.12/example-fastopt.js. You can now open index-fastopt.html in your favorite Web browser!

During development, it is useful to use ~fastOptJS in sbt, so that each time you save a source file, a compilation of the project is triggered. Hence only a refresh of your Web page is needed to see the effects of your changes.

Run the tests

To run the test suite, execute the task test. If you have installed Node.js, you can use that runtime to run the tests, which is faster:

> set scalaJSStage in Global := FastOptStage
> test

The fully optimized version

For ultimate code size reduction, use fullOptJS. This will take several seconds to execute, so typically you only use this for the final, production version of your application. While index-fastopt.html refers to the JavaScript emitted by fastOptJS, index.html refers to the optimized JavaScript emitted by fullOptJS.

If Node.js is installed, the tests can also be run in their fully optimized version with:

> set scalaJSStage in Global := FullOptStage
> test
