Error, Empty, Loading ​

Handling all possible states is critical for both user experience and reliability. Every asynchronous flow must clearly define what happens when data is loading, empty, successful, or has failed.

Guidelines ​

  • Always handle success, error, pending/loading, and empty states.
  • Never leave error or loading states unhandled.
  • Typed error objects should be used for clarity in monitoring and for providing actionable messages to the user.
  • Messages shown to users should be clear and helpful, while detailed error logs should go to monitoring tools.
