Seven domain-eng splits peel ~200 LOC of read endpoints out of
`api/subsonic.ts`:
- `subsonicStreamUrl.ts` — `buildStreamUrl`, `coverArtCacheKey`,
`buildCoverArtUrl`, `buildDownloadUrl` (token-signed URL builders
for the four /rest endpoints we hand to the browser).
- `subsonicStarRating.ts` — `getStarred`, `star`, `unstar`,
`setRating`, `probeEntityRatingSupport`. `setRating` still triggers
the lazy `navidromeBrowse` cache invalidation; the same-folder
lazy import path is preserved.
- `subsonicSearch.ts` — `search`, `searchSongsPaged`.
- `subsonicScrobble.ts` — `scrobbleSong`, `reportNowPlaying`,
`getNowPlaying`.
- `subsonicAlbumInfo.ts` — `getAlbumInfo2`.
- `subsonicLyrics.ts` — `getLyricsBySongId`.
- `subsonicGenres.ts` — `getGenres`, `getAlbumsByGenre`.
63 external call sites migrated to direct imports. Four `vi.mock`
targets in the store-level tests pointed at `../api/subsonic` and
were updated to the new module paths.
Pure code-move. subsonic.ts: 762 → 561 LOC (−201).
First Phase F slice. Splits the 1333-LOC `api/subsonic.ts` along its
two most obvious axes:
- `subsonicTypes.ts` — all ~24 exported interfaces + type aliases
(album/song/artist/playlist/directory/genre/now-playing/radio,
random-songs filters, three statistics shapes, search + starred
results, AlbumInfo, structured-lyrics types, etc.) plus the
`RADIO_PAGE_SIZE` constant.
- `subsonicClient.ts` — token-auth + `getClient` + `api<T>()` +
`libraryFilterParams` + `secureRandomSalt` / `getAuthParams` /
`SUBSONIC_CLIENT`. The credential-bearing API helpers
(`pingWithCredentials`, `apiWithCredentials`, `restBaseFromUrl`,
`probeInstantMixWithCredentials`) stay in `subsonic.ts` for now —
they could move into the client module in a follow-up.
66 external call sites migrated to direct imports from the new
modules (no re-export shims in `subsonic.ts`). Pure code-move;
contract test stays green.
subsonic.ts: 1333 → 1078 LOC (−255).
* Enhance CachedImage and ArtistDetail components with improved image caching and priority handling
- Refactor CachedImage to utilize a priority system for image loading based on viewport visibility, improving performance during scrolling.
- Update useCachedUrl to accept an optional getPriority function for better cache management.
- Optimize ArtistDetail and Artists components by using useMemo for cover art URLs, reducing redundant calculations and improving rendering efficiency.
- Adjust image loading logic in CachedImage to ensure smoother transitions and avoid unnecessary fetch requests.
* perf(ui): unblock IDB cover art, stabilize mainstage rails and virtual lists
Let IndexedDB reads bypass the network concurrency slot so cached thumbnails
paint without queueing behind remote fetches; debounce disk eviction during
heavy scrolling.
Fix mainstage horizontal rails: dedupe album/song ids for React keys, widen
artwork budget overscan, avoid resetting the budget on list append, and raise
Home initial artwork budgets. CachedImage treats already-decoded images as
loaded; rail cards load cover images eagerly.
Refresh dynamic color extraction and extend virtual scrolling / scroll roots on
Albums, Artists, Playlists, and related surfaces.
Remove local agent-only commit instructions from the repository tree.
* perf(virtual): viewport-based overscan for main scroll lists
Drive TanStack Virtual overscan from measured scroll height so each list
renders about one screen of extra rows above and below the viewport for
snappier scrolling on Albums, Artists (list mode), and Tracks virtual song list.
Introduce useResizeClientHeight helpers (ID + ref) for ResizeObserver-based
clientHeight tracking.
* docs(changelog): note PR #468 UI cover cache, rails, and virtual lists
Add a coarse summary under 1.46.0 Changed for cover-art pipeline,
mainstage rails, viewport-based overscan, and library/chrome polish.
Extracts the song-list row into a single shared <SongRow> component
used by Tracks Hub Browse, /search and /search/advanced. All three now
share the same five-column layout (Play+Enqueue · Title · Artist ·
Album · Genre · Duration), the same enqueueAndPlay click behaviour,
and the same right-click context menu / drag handler.
The header row is rendered separately via <SongListHeader> (kept
outside the virtualizer scroll container in the Tracks Hub so it
doesn't scroll away).
Both SearchResults and AdvancedSearch now infinite-scroll their song
results via an IntersectionObserver sentinel near the bottom of the
list (rootMargin 600 px). Pagination uses search3's songOffset; the
free-text branch in AdvancedSearch keeps applying genre/year filters
client-side per loaded page. Initial fetches stay at 50 (SearchResults)
and 100 (AdvancedSearch) songs; subsequent pages are 50 each.
Cleanup:
- removed the redundant `(N)` count in the AdvancedSearch songs heading
- dropped the unused `useNavigate` + `psyDrag` + per-page contextMenuSongId
state in both search pages — SongRow handles those internally
- renamed the row-internal CSS classes from `.virtual-song-*` to
`.song-list-row-*` so they read as shared, and switched the mobile
grid breakpoint accordingly

New /tracks route with three sections:
- Hero "Track of the moment" — random pick with play / enqueue / reroll
- Random Pick rail — 18 song cards, rerollable; hero song deduped
- Browse all tracks — virtualized list (@tanstack/react-virtual),
paginated 50 at a time
Browse uses Navidrome's native /api/song?_sort=title&_order=ASC for
proper A-Z order (no Subsonic equivalent), with automatic fallback
to search3 on non-Navidrome servers. Search input drives search3
with 300ms debounce. Bearer token cached module-level, re-auth on 401.
Play button on rows + cards calls a new enqueueAndPlay() helper that
appends to the existing queue (skip if duplicate) and jumps to the
song — different from playSongNow which replaces the queue. Enqueue
button stays opaque (no hover-only).
i18n keys for sidebar.tracks + tracks.* namespace in all 8 locales.
New AudioLines sidebar icon. Sidebar entry inserted between
"All Albums" and "Build a Mix".
Performance: cover thumbnails dropped (uniform layout instead),
RAF-throttled scroll prefetch, hover transforms removed from cards
(WebKitGTK compositing-friendly).
