111 of 122 top-level src/utils/ files move into 16 topic folders (audio,
cache, cover, share, server, playback, playlist, deviceSync, waveform,
mix, format, export, changelog, ui, perf, componentHelpers). True
singletons with no cluster stay at the utils/ root.
Pure file-move: a path-aware codemod rewrote 539 relative-import
specifiers across 275 files; no logic touched. The hot-path coverage
gate list (.github/frontend-hot-path-files.txt) is updated to the new
paths for the 11 gated utils files — a mechanical consequence of the
move, not a CI change. tsc is green.
Four-cut cluster closing out the NowPlaying decomposition. 715 → 391
LOC (−324).
TourCard — Bandsintown tour-dates card with the privacy-prompt
gate (shown before the user opts in), loading state, empty state,
5-item show-more list with date / venue / place, and the
"Tour data via Bandsintown" credit footer.
DiscographyCard — chronological album grid (10×2 = 20 tiles
initial, show-more for the rest), each tile a cached cover-art
thumbnail with a tooltip and click-through to the album page.
useNowPlayingFetchers — the eight cached fetch effects that drove
the page: song meta / artist info / album / top songs / Bandsintown
tour events (+ loading state) / discography / Last.fm track stats /
Last.fm artist stats. Each effect follows the same pattern
(cache hit → seed state, cache miss → fetch + setCache + setState,
cancellation flag on cleanup). All eight makeCache<…> instances
move into the hook module too.
useNowPlayingStarLove — local starred + lfmLoved booleans seeded
from songMeta.starred and lfmTrack.userLoved respectively, plus
toggleStar (star/unstar Subsonic API) and toggleLfmLove
(lastfmLove/Unlove with the session key).
NowPlaying drops the now-unused imports: star/unstar (Subsonic),
getArtist/getArtistInfo/getTopSongs/getSong/getAlbum, the entire
'../api/lastfm' line, fetchBandsintownEvents + BandsintownEvent,
makeCache (was passing through to the page only for cache
instantiation), plus SubsonicAlbum (only the type is still used
inside the hook). The radio + dashboard JSX in the body still
references everything via the hook returns. Pure code move
otherwise.
