@millions-hair-24956, does the LivekitRoom react component gets updated with all the events ? I have a chat window within the LivekitRoom and the chat window keeps getting mounted and unmounted whenever we receive a transcript message from the ai agent.

The

LiveKitRoom

component should not cause repeated mounting and unmounting of its child components, such as a chat window, when events occur. According to the LiveKitRoom documentation, updating props for the

LiveKitRoom

component should not result in the component being repeatedly unmounted and remounted, as this can lead to disconnect errors and other issues. If your chat window is being mounted and unmounted frequently, it might be due to how the component is being updated or how state changes are being handled in your application. Ensure that state updates are not causing the entire component tree to re-render unnecessarily. You might want to check if the state or props that trigger re-renders are being updated correctly and efficiently. Would you like more detailed guidance on how to manage state updates to prevent unnecessary re-renders?

@millions-hair-24956, yes please. I might have implemented it incorrectly.

To manage state updates efficiently and prevent unnecessary re-renders in your

LiveKitRoom

component, follow these steps: 1. Use Contexts Appropriately: Ensure that you are using React contexts to manage state that needs to be shared across multiple components. The

LiveKitRoom

component provides a

RoomContext

that can be used by child components to access the room state without passing props down the component tree. This can help reduce unnecessary re-renders. 2. Optimize State Management: Use hooks like

useState

and

useEffect

wisely. Avoid setting state in a way that causes the entire component tree to re-render. For example, if you are updating state based on incoming messages, ensure that only the relevant components are re-rendered. 3. Memoization: Use

React.memo

or

useMemo

to memoize components or values that do not need to be recalculated on every render. This can help prevent unnecessary re-renders of components that depend on stable values. 4. Component Structure: Structure your components so that only the parts of the UI that need to update are affected by state changes. For example, if your chat window is being re-rendered due to state changes in the

LiveKitRoom

, consider separating the chat logic into its own component with its own state management. 5. Event Handling: Ensure that event handlers are not causing unnecessary state updates. For instance, if you are handling transcript messages, make sure that the state updates are minimal and only affect the components that need to respond to those messages. Here's a basic example of how you might structure a chat component within a

LiveKitRoom

to minimize re-renders:

import React, { useState, useEffect, useContext } from 'react';
import { LiveKitRoom, RoomContext } from '@livekit/components-react';

const ChatWindow = React.memo(({ messages }) => {
  return (
    <div>
      {messages.map((msg, index) => (
        <div key={index}>{msg}</div>
      ))}
    </div>
  );
});

const MyLiveKitApp = () => {
  const [messages, setMessages] = useState([]);
  const room = useContext(RoomContext);

  useEffect(() => {
    if (room) {
      const handleNewMessage = (msg) => {
        setMessages((prevMessages) => [...prevMessages, msg]);
      };

      room.on('messageReceived', handleNewMessage);

      return () => {
        room.off('messageReceived', handleNewMessage);
      };
    }
  }, [room]);

  return (
    <LiveKitRoom serverUrl="your-server-url" token="your-token" connect={true}>
      <ChatWindow messages={messages} />
    </LiveKitRoom>
  );
};

export default MyLiveKitApp;
