Fwiw, i use serverside React rendering with a Golang API server. My JS code has an interface layer which interfaces to browser/node, and on first load a balancer throws the request to Node, which makes local API calls to the api server, and renders it all in node.
Technically i use Node, but only to implement a small interface layer for things like http requests. So i don't really consider it a Node app. The real code is all React and Golang.
