Setup

This project uses Scala 3.2.1 and Scala JS. We recommend installing with Coursier, which will also install SBT. You will also need NPM globally installed. To run the project, from the console:

sbt
> ~fastOptJS/webpack           // Compiles to JS and watches for changes

Then, open index.html in any browser. You will have to reload when changing scala sources. To reload automatically when sources change, run ./scripts/serve.sh, which relies on the live-reload package, installable via npm install -g live-reload or yarn global add live-reload. If live-reloading, access the file at localhost:4000 instead of directly.
