callback, or in a `useEffect` that watches the socket ref).

## Parameters

### socket

`Socket`\<`DefaultEventsMap`, `DefaultEventsMap`\> \| `null`

## Returns

`void`

## Example

```typescript
const { socket } = useSocketConnection({ ... });

useEffect(() => {
  setRealtimeSocket(socket);
  return () => setRealtimeSocket(null);
}, [socket]);
```
