Creating Fast-Feeling Web Apps
summary
Claims that delaying a spinner by 300ms delay and using cached listing data as initialData makes apps feel instant; demos show only one network request instead of repeated calls. Uses concrete tools React Query / SWR and patterns like staleTime = 30s to keep data fresh locally, and implements optimistic update with onMutate so UI hides immediately while a 2–3s API call completes (with rollback on failure). Shows code snippets and live demos proving these changes alter perception without faster servers.
