Fetching & Displaying Data

What is the best practice for handling real-time data updates in a list or grid view?

function RealTimeList({ websocket }) {
  const [items, setItems] = useState([]);
  
  useEffect(() => {
    websocket.addEventListener('message', (event) => {
      const update = JSON.parse(event.data);
      
      setItems(current => {
        const index = current.findIndex(item => item.id === update.id);
        if (index === -1) return [...current, update];
        
        const newItems = [...current];
        newItems[index] = { ...newItems[index], ...update };
        return newItems;
      });
    });
  }, [websocket]);

Always refresh the entire list
Ignore real-time updates
Update only changed items efficiently
Efficient real-time updates should: 1) Update only changed items without full re-renders, 2) Implement proper optimistic updates, 3) Handle conflict resolution, 4) Maintain smooth animations and transitions. Additional considerations include: - Implementing proper error recovery - Handling offline scenarios - Managing connection states - Implementing proper UI feedback for updates - Optimizing for performance with large datasets
Remove animation effects
