๐ฌ Chat Room
Chat: Lobby
Custom scopes isolate each room. Messages in "lobby" never leak to "general" โ 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.
SQLite persistence keeps message history across server restarts. Each room's messages are stored in
chat.db and the last 50 are loaded on connect โ no in-memory state required.Multi-room architecture โ open two rooms side by side. Each room's scope is independent, so typing in Lobby has no effect on General.
