These days, full-stack development in Scala is a widespread reality.
But Scala 3 makes it exciting again, and simpler, without disrupting established practices.
This project is a full-stack application in Scala 3. It uses both libraries that have already been published for Scala 3, like circe, and libraries that have not, like akka-http and scalajs-dom, through Scala 3's interoperability with Scala 2.13.
The webpage project is a Scala.js project that uses the scalajs-dom facade to manipulate the HTML document.
It is served by an akka-http server in the webserver project.
The data types are shared across the client and server in the core project.
They are sent across the network in the json format using circe.
You can use sbt to run the application.
sbt:scala3-full-stack-example> webserver / run
[info] running (fork) example.start

Then open the http://localhost:8080 page in your favorite browser.
