---------------------- The `useSocket` hook provided by Wasp is used to access the WebSocket on the client side. It returns a `socket` object for sending and receiving events and an `isConnected` boolean that shows the status of the Socket.IO connection. Wasp automatically connects and establishes a WebSocket connection from the client to the server by default, so you do not need to explicitly call `socket.connect()` or `socket.disconnect()`. However, if you set `autoConnect: false` in your Wasp file, then you should call these as needed. All components using `useSocket` share the same underlying `socket`. Here is an example of how you can use the `useSocket` hook in a React component: ```jsx import React, { useState } from 'react' import { useSocket, useSocketListener, } from 'wasp/client/webSocket' export const ChatPage = () => { const [messageText, setMessageText] = useState('') const [messages, setMessages] = useState([]) const { socket, isConnected } = useSocket() useSocketListener('chatMessage', logMessage) function logMessage(msg) { setMessages((priorMessages) => [msg, ...priorMessages]) } function handleSubmit(e) { e.preventDefault() socket.emit('chatMessage', messageText) setMessageText('') } const messageList = messages.map((msg) => (

{msg.username}: {msg.text}

)) const connectionIcon = isConnected ? '🟢' : '🔴' return ( <>

Chat {connectionIcon}

{messageList}

) } ```
