At least on node you can use http://reagent-project.github.io/docs/master/reagent.dom.server.html

Here’s a very minimal example https://github.com/babashka/nbb/blob/main/examples/reagent-ssr/example.cljs

But we're not sure if it works outside of node?

Those namespaces are only in CLJS since they’re using react from npm

And I don’t have experience ever trying to run reagent on the JVM 🙂

Maybe someone else does..?

Just deciding if I should switch from Rum, as that provides SSR pretty easily

But I'm just learning, maybe I shouldn't get too hung up

Yep, probably best to stick with what already works for you 🙂

Or at least think of the trade-offs before switching.
