Live Admin With Gleam and Lustre
· 11 min read
Curling IO's admin panel should feel instant when a club manager is working through a season setup. Toggle a setting, save a discount, move between product sections: the page should respond without a full reload.
Version 2 works, but every form submission reloads the page. Version 3's admin is a single Lustre server component running on the BEAM. One WebSocket connection, one long-lived Erlang process per session. Every interaction goes over that WebSocket and comes back as a DOM patch. The page never reloads, and there's no client-side JavaScript framework.
