wiringbits-webapp-utils VS scalajs-react

Well, I solved my weird issue by setting Scala 2.13 as the default version and cross compile all modules but one (ref).

Then there's scalajs-react, which can be integrated with existing React ecosystem, but it's just sooo compex: macros, 5-6 type parameters, hundreds and hundreds of cryptic types. We decided to stick with TypeScript instead.

Or the OG React Scala.js library: https://github.com/japgolly/scalajs-react

Japgolly has put a ton of time and care into https://github.com/japgolly/scalajs-react which is a complete React binding in scalajs. This paired with something like Diode (https://github.com/suzaku-io/diode) and you get a full frontend solution in scalajs.

We've got server-side rendering with scalajs-react and scala-graal. Here's a tutorial if anyone's interested. What's really cool about scala-graal is that it has some pretty cool caching so that even with dynamic inputs, you can render pages in nanoseconds (as opposed to 10+ or even 100+ ms).

You can use React with Scala.js, and also most other common JS libraries. Or you can use a Scala.js specific library like Laminar, which I haven't tried myself but it looks nice.

I don't have a lot of experience with it, but many seem to be very pleased with it. Interop with JS is good and you can use React and other common JS libraries, but there is also Scala.js specific frameworks like Laminar.

https://github.com/japgolly/scalajs-react is pretty heavily used as well, and fairly active as a project. In short, building it off of that wouldn't be a huge risk over typescript, and might even be a net win in the long run, as you could re-use some stuff from the backend in the front-end.
