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.
