56-57: Avoid monkey patching the global objectAssigning the Socket.IO instance to the global object using
(global as any).iocan lead to maintenance and type safety issues. Consider managing theioinstance through module scope or a dedicated singleton pattern.
22-53: Use a logging library instead ofconsole.logUsing
console.logis suitable for development but not recommended in production code. Consider using a logging library that supports log levels and better log management.apps/demo-game/src/pages/play/cockpit.tsx (2)

99-212:
Remove commented-out code to improve readabilityThe large block of commented-out code from lines 99 to 212 reduces code readability. Removing it can clean up the codebase since version control systems keep track of code history.
173-173: Use appropriate heading level for nested contentUsing an
h1element for the countdown timer may not be semantically appropriate within the sidebar. Consider using a smaller heading level likeh3or a styleddivto match the surrounding content.Apply this diff to adjust the heading level:
- {timeRemaining > 0 && <h1>Time Left: {timeRemaining} seconds</h1>} + {timeRemaining > 0 && <h3>Time Left: {timeRemaining} seconds</h3>}apps/demo-game/src/pages/api/countdown.ts (1)
1-351: Remove obsolete commented-out codeThe extensive block of commented-out code from lines 1 to 351 makes the file cluttered and hard to read. Since version control systems keep track of code history, it's better to remove this code to improve readability.

Restrict 'start-countdown' event to authorized clients
Any connected client can emit the 'start-countdown' event, which can lead to unauthorized users starting or resetting the countdown. Implement authentication or authorization checks to ensure only authorized users (e.g., admins) can initiate the countdown.

🛠️ Refactor suggestion
Provide a consistent response when Socket.IO server is already initialized
Currently, when the Socket.IO server is already initialized, the response is ended without any feedback to the client. This may lead to confusion for clients making the request. Consider sending a JSON response indicating that the Socket server is already running.
Apply this diff to improve the response:
if (res.socket.server.io) {
- res.end()
+ res.status(200).json({ message: 'Socket server already initialized' })
return

🛠️ Refactor suggestion
Enhance socket connection reliability and user feedback.
The socket initialization needs improvements in error handling and user feedback:
- Add a maximum reconnection attempts limit
- Provide user feedback for connection status
- Add loading state management
Apply these improvements:
useEffect(() => {
const socketInstance = io(process.env.NEXT_PUBLIC_APP_URL, {
reconnection: true,
- reconnectionAttempts: 5,
+ reconnectionAttempts: 3,
reconnectionDelay: 1000,
timeout: 10000,
transports: ['websocket', 'polling'],
})
+ const [isConnecting, setIsConnecting] = useState(true)
+ const [connectionError, setConnectionError] = useState<string | null>(null)
if (!socketInstance.connected) {
fetch('/api/socket')
}
socketInstance.on('connect', () => {
console.log('Admin connected')
setSocket(socketInstance)
+ setIsConnecting(false)
+ setConnectionError(null)
})
socketInstance.on('connect_error', async (error) => {
- console.error('Connection error admin:', error)
+ setConnectionError(`Connection error: ${error.message}`)
+ setIsConnecting(false)
await fetch('/api/socket')
})
return () => {
socketInstance.disconnect()
}

🛠️ Refactor suggestion
Improve countdown implementation with validation and feedback.
The current countdown implementation needs several improvements:
- Input validation is minimal
- No error handling for socket emit
- No feedback on countdown start
- No visual indication of active countdown
Apply these improvements:

<CardTitle>Countdown</CardTitle>

@rschlaefli Here is a solution for the countdown (without front end perks) I came up with. I solved it with sockets. The admin broadcasts a new countdown time, which is count down in the back end, and the players just listen to the new value and update it in the front end. That way it is in real-time and all players have the same countdown. Not sure if this approach is over-kill or might introduce problems, so let me know what you think :)! |

🛠️ Refactor suggestion
Enhance error handling for socket connection failures.
The current error handling only logs the error and attempts to fetch /api/socket. Consider implementing a more robust error handling strategy.
socket.on('connect_error', async (error) => {
console.error('Connection error player:', error)
- await fetch('/api/socket')
+ try {
+ const response = await fetch('/api/socket')
+ if (!response.ok) {
