PhoenixKitAI.Realtime.Session (PhoenixKitAI v0.12.2)

Copy Markdown View Source

Owns one xAI realtime WebSocket connection (Xai.Realtime) on behalf of a single Playground LiveView, forwarding audio chunks and events to it as plain messages.

Runs under PhoenixKitAI.Realtime.Supervisor (a DynamicSupervisor contributed via PhoenixKitAI.children/0) with restart: :temporary — a dead session is not auto-restarted, the LiveView re-triggers "start voice" itself.

Cleanup

Xai.Realtime.connect_tts/1 is called from init/1, so the WebSockex connection links to this process, not the owning LiveView — a socket crash only takes down the session. The reverse direction (LiveView goes away) is handled by monitoring live_view_pid: LiveView's own terminate/2 isn't reliably called without trap_exit, so closing the connection is driven from here via the :DOWN message instead.
