Agent Chat Transcript | LiveKit Documentation

Usage

Hi, how are you?

I'm good, thank you!

This is a longer message that should wrap to the next line.

Great I'm responding with an even longer message to see how it wraps.

'use client';

import { 
  useSession, 
  useAgent,
  useSessionContext,
  useSessionMessages, 
} from '@livekit/components-react';
import { AgentSessionProvider } from '@/components/agents-ui/agent-session-provider';
import { AgentChatTranscript } from '@/components/agents-ui/agent-chat-transcript';

const TOKEN_SOURCE = TokenSource.endpoint('/api/token');

export function Demo() {
  const { state } = useAgent();
  const session = useSessionContext();
  const { messages } = useSessionMessages(session);

  return (
    <AgentChatTranscript
      agentState={state}
      messages={messages}
    />
  );
}

export default function DemoWrapper({ session }) {
  const session = useSession(TOKEN_SOURCE);

  return (
    <AgentSessionProvider session={session}>
      <Demo />
    </AgentSessionProvider>
  );
}
