I’m using React Chat component. Just wanted to know how to send and receive the text. Is there any specific hooks or components for that?

To send and receive text using the React Chat component in LiveKit, you can use the

useChat

hook or the pre-built

Chat

component: • Using the
useChat
Hook:

Copy code

function ChatComponent() {
  const { chatMessages, send, isSending } = useChat();

  return (
    
      {chatMessages.map((msg) => (
        
          {msg.from?.identity}: {msg.message}
        
      ))}
      
    
  );
}

◦ The

useChat

hook provides

chatMessages

send

, and

isSending

properties. ◦ `chatMessages`: An array of received chat messages. ◦ `send`: A function to send a new message. ◦ `isSending`: A boolean indicating if a message is currently being sent. • Using the
Chat
Component:

Copy code

import { Chat } from '@livekit/components-react';
import '@livekit/components-styles';

export default function Room() {
  return (
    
  );
}

◦ The

Chat

component provides a pre-built UI for chat functionality. ◦ It includes message display, input field, and send button out-of-the-box. Let me know if you need help with specific implementation details! Sources: Add chat to your React app | LiveKit Docs | packages/core/src/observables/dataChannel.ts

Here’s a simple JavaScript example to help you send and receive messages using the

Hey there! If you want to receive messages in a React app using LiveKit, here are a couple of handy hooks you can try out: • useChat
Hook: This one’s perfect if you’re focusing on chat features. It gives you a list of received messages through the

chatMessages

property, making it super straightforward.

Copy code

import { useChat } from '@livekit/components-react';

function ChatInterface() {
  const { chatMessages } = useChat();

  return (
    
      {chatMessages.map((msg, index) => (
        
          {msg.from?.identity}: {msg.message}
        
      ))}
    
  );
}

• useDataChannel
Hook: This one’s a bit more flexible—it lets you send and receive messages through a data channel, whether you want to filter by topic or not. Great if you need more control.

Copy code

import { useDataChannel } from '@livekit/components-react';

function MessageReceiver() {
  const { message } = useDataChannel((msg) => {
    console.log("Received message:", msg);
  });

  return (
    
      Latest message: {message?.message}

    
  );
}

So, if you’re building chat-specific stuff,

useChat

is your friend. But if you want more control over messaging,

useDataChannel

has got you covered. Feel free to ask if you want me to help you with anything else!
