Is this project abandoned ?

Seems to be years since the last release and hence it is based on ancient versions.

Is it dead and gone?

seems like that is the case. I wanted to use Scala.js but for backend, it cant be used due to no direct nodejs support.
on front end, it needs bindings for React or other frameworks.

This project, like any other project that provides "only facade types" to a JS library, has been superseded by ScalablyTyped. ScalablyTyped automatically produces Scala.js facades for JS libraries based on their TypeScript definition files. There is no need to manually maintain facade libraries like this library anymore.
