Answer

Strategies include:

  • On-Demand Fetching: Fetch data only when needed to reduce initial load times.
  • Polling: Regularly update information to ensure users see real-time data, but consider the server load.
  • WebSockets: For real-time updates, providing a more dynamic user experience.
  • Data Caching: Use libraries like React Query to cache results for performance improvements. Have a fallback strategy for error handling and implement loading states to enhance user experience.
