Unlocking the Full Potential of Scala Web Development with Scala 3

This proposal aims to integrate Scala 3 support into the Scala Webapp Template, providing a more accessible, reliable, and powerful solution for developers interested in building web applications using Scala and Scala.js. The integration will involve updating the backend and frontend code to utilize new syntax and features of Scala 3, ensuring compatibility with existing Scala 2.13 code through cross-compilation, and updating libraries and dependencies as necessary. The proposed approach also includes testing, documentation, and optimization of the updated components.
