Because every fetch can take time or fail, and a blank screen makes the app feel broken. Track three states, loading, error, and success, and show a meaningful UI for each so the user always knows what is happening.
Because users can recover from transient failures like a dropped network. A clear error message and a retry option turn a failure into a recoverable experience, instead of leaving the user stuck with no path forward.
Use an axios interceptor to catch errors globally, show a toast, and return a normalized error shape. Components then handle one consistent error shape, instead of each parsing errors differently.
