Loading & Async State Patterns

Design reference for skeletons, inline loading, and error/retry states.

+

1. Markets List Skeleton

+

Shown while the markets widget fetches data.

+
+ +
+
+ + + + {/* Surface 2 – Event detail skeleton */} +
+

2. Event Detail Skeleton

+

Shown while the event detail page loads.

+ +
+ + + + {/* Surface 3 – Events table skeleton */} +
+

3. Events Table Skeleton

+

Shown via Next.js loading.tsx on the events list page.

+ +
+ + + + {/* Inline loading button */} +
+

Inline Loading – AsyncButton

+

Spinner replaces icon; text changes to loading copy.

+
+ + Place Bet + + + Submit Form + +
+
+ + + + {/* Error + retry banner */} +
+

Error + Retry Banner

+

Inline banner with optional retry callback.
