I’m not sure on if we’re talking about the same thing here but as someone who disables JS by default, any federated service without some form of SSR is inherently clunky to use. Half my allowlist is Masto instances I’ve barely visited once or twice because website boy is a jerk and ruined a reasonably well functioning SSR UI.
I don’t get why the language would make a difference in how you deploy the frontend. You can already host the BE and FE on different hosts with the right reverse proxy config. This just replaces the Node in lemmy-ui with Rust+Leptos.
