Hey guys, just wanted to share my repo https://github.com/dborisenko/scalajs-react-components
. I migrated Semantic UI React to the latest version of React (16.7) and scalajs-react (1.3.1, because the upstream repo was quite outdated). And I ported some more components to scalajs-react, which might be useful: React Sortable (HOC), react-trello, STORM React Diagrams, react-markdown, React Syntax Highlighter. My aim was not migrate to the latest version of scalajs-react everything, but migrate only that component which I needed (in particular , only Semantic UI). That is why I dropped a lot of components from my repo and I cannot make PR to the upstream repo. So, if you think, it could be useful, feel free to use.
