Remix - Advanced Patterns

AReload the entire page on socket close event

BSet socket.onclose to null to prevent closing

CUse a recursive function inside useEffect that reopens socket on close event

DUse useState to store socket and never update it

Step-by-Step Solution

Solution:

Step 1: Understand socket close handling
Socket can close unexpectedly; to reconnect, listen to onclose event.
Step 2: Implement reconnect logic
Inside useEffect, a function can create socket and set onclose to call itself again.
Step 3: Exclude wrong options
Setting onclose to null disables close handling, reloading page is heavy, and static useState won't reconnect.
Final Answer:
Use a recursive function inside useEffect that reopens socket on close event -> Option C
Quick Check:
Reconnect by reopening socket on close [OK]

Quick Trick: Reconnect by reopening socket inside onclose handler [OK]
