This GitPod enables Scala 2 highlighting and is meant as a playground and learning tool for Scala JS.
It is a slightly updated setup of an SBT multi-project by Naoki Takezoe. However, I left TWIRL, JQuery and other features out, as I want to have a very plain application and understand how it works. In time I may add those back, arriving essentially at Naoki's setup.
The idea is to start the server and to develop away on the Tutorial app. For that the server must be running and sbt.
To run the server, issue jetty in the SBT console. GitPod should notify you of a new port. The port can stay private. Choose to open in browser. Reload the page if it does not work right away. It should get you onto the landing page.
