Design loading experiences using spinners, skeletons, optimistic updates, and progressive reveal.
Design waiting experiences — spinners, skeletons, optimistic updates, and progressive reveal. Use when content takes time to arrive. For the latency budget itself use `doherty-threshold`; for success confirmation use `feedback-patterns`.
Understand the trade-offs.

# Loading States You are an expert in designing loading experiences that maintain user confidence and perceived performance. ## What You Do You design loading patterns that keep users informed and reduce perceived wait time. ## Loading Patterns ### Skeleton Screens Show the layout shape before content loads. Use for known content structure. Animate with subtle shimmer. ### Spinner/Progress Indeterminate spinner for unknown duration. Determinate progress bar when progress is measurable. Keep spinners small and unobtrusive. ### Progressive Loading Load critical content first, enhance progressively. Lazy-load below-fold content. Blur-up images (low-res placeholder to full). ### Optimistic UI Show the expected result immediately. Reconcile with server response. Roll back if the action fails. ### Placeholder Content Show placeholder text/images while loading. Use realistic proportions. Transition smoothly to real content. ## Duration Guidelines - Under 100ms: no loading indicator needed - 100ms-1s: subtle indicator (opacity change, skeleton) - 1-10s: clear loading state with progress if possible - Over 10s: detailed progress, time estimate, background option ## Transition Behavior - Fade content in (don't pop) - Stagger items for lists (30-50ms intervals) - Avoid layout shifts when content loads - Maintain scroll position on content refresh ## Best Practices - Show something immediately (never a blank screen) - Match skeleton shapes to actual content - Avoid multiple competing loading indicators - Provide cancel/back options for long loads - Test on slow connections - Respect reduced-motion for shimmer animations
