Why multiple states
Goal: Cover all data states for a smooth UX.
- Loading: show skeletons
- Error: short, helpful text
- Empty: explain and suggest next action
- Success: render list or detail
Skeleton basics
Skeletons hint at layout while data loads. Keep them light, not flashy, and avoid layout shift when content arrives.
Demo: loading/error/empty/success
Simulate fetching: show skeletons while loading, then render list; toggle to see error and empty flows.
<div id="root"></div>
Empty state tips
Empty state should set expectations and suggest a next step (e.g., “No items yet. Add one.”). Keep copy short and friendly.
Error state tips
Error state: show a brief message and a retry. Do not expose raw stack traces on mobile; keep it actionable.
Skeleton checklist
Skeletons do:
- Match final layout size
- Use subtle shimmer
- Disappear quickly
Don’t:
- Block interactions unnecessarily
- Cause layout jumps
State coverage check
Recap
Recap: Cover loading, error, empty, and success. Use light skeletons while loading and keep messages short and actionable.
