💬 Chat Room
Chat: Random
Custom scopes isolate each room. Messages in "lobby" never leak to "general" — each room has its own broadcast channel built with
Scope::build().Session-scoped usernames persist across tabs. Your username is stored in SESSION scope, so switching rooms or opening a new tab keeps the same identity.
Presence + typing indicators update in real time. When a user disconnects, the
onDisconnect hook removes them from the room's user list.addScope() lets a context join a broadcast channel mid-flight. The room page starts in TAB scope for private input, then adds the room scope for shared messages.
In-memory message store keeps this demo self-contained. Messages persist as long as the server runs — no database required for a working chat.
Multi-room architecture — open two rooms side by side. Each room's scope is independent, so typing in Lobby has no effect on General.
