fix : correct concede message and resolve pre-existing ESLint errors in OnlineDebateRoom#346
Conversation
…n OnlineDebateRoom
📝 WalkthroughWalkthroughThis PR addresses a concede message display bug and various code quality improvements in OnlineDebateRoom.tsx. The primary fix ensures that only the opponent receives a "You win!" message when a user concedes, rather than both participants. Additional changes include ESLint cleanup, removal of unused variables, parameter renaming, and refactored WebSocket/spectator handling logic. Changes

fetchRoomParticipantsfrom this effect's dependency array to prevent unnecessary WebSocket reconnections.
fetchRoomParticipantsdepends oncurrentUser, which changes when the user profile loads. SincecurrentUseris not stable, includingfetchRoomParticipantsin the dependency array causes this effect to re-run and recreate the WebSocket connection whenever the user data updates.However,
fetchRoomParticipantsis only called insiderws.onopen(line 1120) within a delayed callback, where it will capture the latest version through closure. It does not need to be listed as a dependency.If ESLint complains about the missing dependency, add an
eslint-disable-next-linecomment rather than including it in the array, or move thefetchRoomParticipants()call to a separate effect triggered by socket readiness.🤖 Prompt for AI Agents

Add a null check to guard against race condition in concede handler.
The fix correctly filters so only the opponent sees "You win!", but currentUserIdRef.current may be null if a concede message arrives before the user's profile loads. In that case, data.userId !== null would be true, incorrectly showing "You win!" to the wrong participant. Add a defensive null check:
Suggested fix
case "concede":
// FIX: Only show "You win!" to the opponent, not the user who conceded
- if (data.userId !== currentUserIdRef.current) {
+ if (currentUserIdRef.current && data.userId !== currentUserIdRef.current) {
setDebatePhase(DebatePhase.Finished);
setPopup({
show: true,
message: `${data.username || "Opponent"} has conceded the debate. You win!`,
isJudging: false,
});
}
break;This pattern is already used elsewhere in the file (line 141: Boolean(currentUserIdRef.current)) and in sibling functions for defensive checks after extracting ref values.

Summary
Fixes a bug where both users received "You win!" when one user conceded
the debate. Also resolves 13 pre-existing ESLint errors in the file.
Root Cause
The WebSocket
concedeevent was broadcast to all participants withoutchecking who was the sender, causing the conceding user to also see "You win!".
Fix
Added
data.userId !== currentUserIdRef.currentcheck incase "concede"WS handler so only the opponent sees "You win!". The conceding user already
sees "You have conceded" from
