Bringing LiveView to the Client with Popcorn
summary
Popcorn runs Elixir on the browser via Atom VM and WebAssembly so Phoenix LiveView code executes client‑side, claiming sub‑millisecond interaction and offline behavior; the proof shows a forms demo where shutting down the server keeps validation and local state and later reconnects to sync assigns to a server mirror process (conflict resolution via handle_sync). The AtomVM bundle is ~11 MB (5 MB compressed), a mix generator produces the local subproject, and the feature is working but not production ready.
