scalajs-react

Lifts Facebook's React library into Scala.js and endeavours to make it as type-safe and Scala-friendly as possible.

Provides (opt-in) support for pure functional programming, with additional modules for Cats, Cats Effect, and Monocle.

Comes with utility modules extra and test, helpful for React in Scala(.js), rather than React in JS. Includes a router, testing utils, performance utils, more.
