Adds an `empty` snippet prop to FontVirtualList and supplies it from the
sidebar FontList. Settled queries with zero results now render a centered
"No typefaces found" label instead of a blank list area.
Both names were vague or overloaded:
- fontStore / FontStore -> fontCatalogStore / FontCatalogStore
Three font-related stores live in this slice; the new name names the
paginated catalog specifically.
- appliedFontsManager / AppliedFontsManager -> fontLifecycleManager /
FontLifecycleManager
"Applied" collided with the filter-side appliedFilterStore (different
meaning). The class actually orchestrates a load-use-evict lifecycle
with FontBufferCache + FontEvictionPolicy + FontLoadQueue
collaborators, so "Manager" is justified. Companion types file moved
alongside (appliedFonts.ts -> fontLifecycle.ts).
Directories, file basenames, factory (createFontStore ->
createFontCatalogStore), and the AppliedFontsManagerDeps interface all
renamed. All consumers (ComparisonView, SampleList, FontList,
FontApplicator, FontVirtualList, FilterAndSortFonts bindings,
createFontRowSizeResolver, mocks) updated.
- Add 'total' prop to VirtualList for accurate scrollbar height in pagination scenarios
- Add 'onNearBottom' callback to trigger auto-loading when user scrolls near end
- Update FontVirtualList to forward the new props
- Implement auto-pagination in SuggestedFonts component (remove manual Load More button)
- Display loading indicator when fetching next batch
- Show accurate font count (e.g., "Showing 150 of 1920 fonts")
Key changes:
- VirtualList now uses total count for height calculation instead of items.length
- Auto-fetches next page when user scrolls within 5 items of the end
- Only fetches if hasMore is true and not already fetching
- Backward compatible: total defaults to items.length when not provided
- Add gcTime parameter to TanStack Query config
- Add response validation in fetchFn with detailed logging
- Add fallback to Fontshare API when proxy fails
- Add USE_PROXY_API flag for easy switching
- Fix FontVirtualList generic type constraint
- Simplify font registration logic
- Add comprehensive console logging for debugging
Fixes: Query data cannot be undefined error
