Well you could run it as a sort of rendering layer in front of your backend, and talk to your phoenix app on an internal API or local socket. May not be worth it though. Unlike next, I don‘t think you can even run this as SPA only.

I think for remix to be able to do what it does, it kind of needs to run as a JS (not node!) backend, because a big part of it is running react on the server. Also, you are literally writing the server and client code in the same file. Closure and Reason which have strong react ports/bindings might be able to do it, but otherwise I don‘t see how.

What other backends need is probably a totally different framework, that wraps up a react server renderer with native language bindings. Might be neat, but totally different.
