runtime
by assistant-ui2 months ago15Guide to the assistant-ui runtime system, single-thread state, and the imperative runtime API in @assistant-ui/react. Use when creating a runtime (useLocalRuntime with a ChatModelAdapter, useExternalStoreRuntime for Redux/Zustand, useRemoteThreadListRuntime), wiring AssistantRuntimeProvider, or reading/mutating thread, message, and composer state and events. Covers the unified hooks useAui, useAuiState, useAuiEvent (composer.send, thread.runStart, thread.runEnd), legacy hooks (useAssistantRuntime, useThreadRuntime, useMessageRuntime, useComposerRuntime, useThread, useThreadMessages), the AssistantRuntime/ThreadRuntime/MessageRuntime/ComposerRuntime hierarchy, thread operations (append, cancelRun, message().edit/reload), capabilities, and types (ThreadMessage, MessagePart, MessageStatus, ChatModelRunResult). Use for provider \"Cannot read property of undefined\" errors or state not updating. For multi-thread list UI and switching between conversations use thread-list instead.
