I haven't seen client-side form validation specifically, yet. However, there are several projects that use Scala.js effectively, among which:
- A basic setup with PlayFramework, where client-side JS is written in Scala.js
- A more significant example with PlayFramework essentially demonstrating the Scala.js actors proof-of-concept
- Other projects written in Scala.js but with nothing to do with Play, but that demonstrate Scala.js' power to varying degrees.
- Roll, probably the most significant Scala.js project so far.
