## Notes

youi is a framework for user interfaces and applications in Scala and Scala.js, written for web, mobile and desktop. Its app module joins client and server code in one project: the compiled Scala.js front end is served by a JVM server.

Projects are set up with the youi-plugin for sbt or with the library dependencies declared by hand. The tutorial in the app module, which presumes sbt, is the project's own walkthrough.

OUTR Technologies, LLC holds the copyright in the MIT-licensed code.

## Worth knowing

The README says heavy development is under way toward 1.0, and the newest version on Maven Central was uploaded in 2021.
