Each src/locales/<lang>.ts (~1800 LOC) becomes a folder src/locales/<lang>/
with one module per i18n namespace (44 each) plus an index.ts barrel that
reassembles <lang>Translation in the original key order.
Mechanical, script-driven split with a JSON round-trip check: every
locale object is byte-identical to its pre-split form. i18n.ts is
unchanged — './locales/<lang>' now resolves to the folder index.
The per-namespace settings.ts files land ~440-460 LOC; a single i18n
namespace is the natural, non-arbitrary split unit for a flat string
table, so they are intentionally left whole.
The prefetch worker / replan orchestration and its shared module state
(pendingQueue, workerRunning, debounceTimer, graceEvictTimer) stay
entirely untouched in hotCachePrefetch.ts. Extracted only what does not
touch that state:
- hotCachePrefetch/helpers.ts pure helpers — entryKey, byte
estimators, debounceMs, frontend
debug log, PREFETCH_AHEAD, PrefetchJob
- hotCachePrefetch/analysisPrune.ts self-contained analysis-queue prune
cluster (its own analysisPruneTimer +
lastAnalysisPruneSig state, fully
encapsulated behind a
resetAnalysisPruneState wrapper)
Verbatim moves. The orchestration core diff is import-block + the three
analysis-cleanup lines collapsing to resetAnalysisPruneState() — nothing
else. The MainApp call site imports initHotCachePrefetch unchanged.
Each listener/subscription concern moves into its own module under
store/audioListenerSetup/; initAudioListeners just composes them in the
original setup / teardown order:
- audioEngineListeners audio:* + analysis:* Tauri listeners
- initialAudioSync one-shot startup sync to the Rust engine
- authSyncListener auth-store + analysis-storage subscriptions
- mprisSync MPRIS / OS media-controls sync
- radioMprisMetadata radio ICY StreamTitle -> MPRIS
- discordPresence Discord Rich Presence sync
Verbatim code-move — listener registration, handler bodies, local state
and the exact cleanup order are all preserved. The MainApp call site and
the three playerStore.*.test.ts suites import initAudioListeners
unchanged.
imageCache.ts keeps the orchestration entry points + re-exports; the
internals move into imageCache/ with an acyclic dependency graph:
- constants.ts DB / cache size knobs
- blobCache.ts in-memory LRU blob map + inflight reads
- urlPool.ts refcounted shared object URLs
- netFetchScheduler.ts priority-ordered network fetch slots
- idbStore.ts IndexedDB open / read / write / evict
- coverSiblings.ts cover-size sibling probing + upgrade race
Verbatim function-body moves. The only non-move changes are three
named wrappers (cancelScheduledEvict, clearAllUrlEntries, clearCoverState)
that let clearImageCache reach cross-module state — each is the original
lines wrapped in a function, behaviour identical. All seven importers
import from utils/imageCache unchanged.
Extract the GitHub release probe, download/relaunch state and the markdown
changelog renderer out of AppUpdater.tsx:
- utils/appUpdaterHelpers.ts isNewer, fmtBytes, pickAsset, types
- hooks/useAppUpdater.ts release probe + download/relaunch handlers
- components/appUpdater/Changelog.tsx
Pure code-move, no behaviour change. The AppShell call site is unchanged.
Extract the canvas frequency-response math, the custom vertical fader, the
AutoEQ parser, and the AutoEQ search panel out of Equalizer.tsx:
- utils/eqCurve.ts biquadPeakResponse + drawCurve
- utils/autoEqParse.ts AutoEq types + parseFixedBandEqString
- components/equalizer/VerticalFader.tsx
- hooks/useAutoEq.ts AutoEQ search/apply state
- components/equalizer/AutoEqSection.tsx
Pure code-move, no behaviour change. Both call sites (AudioTab, PlayerBar)
default-import Equalizer unchanged.
* refactor(album-detail): extract sanitizeFilename + useAlbumDetailData
Move sanitizeFilename into utils/albumDetailHelpers.ts. Pull the album +
related-albums fetch and the starred state seeds (isStarred,
starredSongs) into hooks/useAlbumDetailData.ts.
AlbumDetail.tsx: 511 → 483 LOC.
* refactor(album-detail): extract useAlbumOfflineState hook
Move the four primitive-selector offline status reads (cache map +
job-status filters + progress totals) into hooks/useAlbumOfflineState.ts.
Keeps the re-render minimisation comment with the code that needs it.
AlbumDetail.tsx: 483 → 461 LOC.
* refactor(album-detail): extract useAlbumDetailSort hook
Pull sortKey/Dir/clickCount state, the 3-click natural-reset cycle in
handleSort, and the displayedSongs memo (filter + sort comparator) into
hooks/useAlbumDetailSort.ts. Rating comparator keeps the same priority
chain as the row renderer.
AlbumDetail.tsx: 461 → 414 LOC.
* refactor(album-detail): extract AlbumDetailToolbar subcomponent
Pull the search input + bulk-action cluster (selection count, add-to-
playlist popover, clear-selection button) into
components/albumDetail/AlbumDetailToolbar.tsx. Parent retains showPlPicker
to coordinate the popover close with selection clears.
AlbumDetail.tsx: 414 → 369 LOC.
* refactor(user-mgmt): extract formatLastSeen helper
Move the relative-time formatter (with the Navidrome
'0001-01-01T00:00:00Z' epoch guard) into utils/userMgmtHelpers.ts.
UserManagementSection.tsx: 515 → 499 LOC.
* refactor(user-mgmt): extract useUserMgmtData hook
Pull users + libraries state, sequential admin-API fetch, and the
nginx-friendly error normalisation into hooks/useUserMgmtData.ts.
UserManagementSection.tsx: 499 → 464 LOC.
* refactor(user-mgmt): extract useUserMgmtActions hook
Bundle handleSave (covers create + edit + library assignment),
handleSaveAndGetMagic (new non-admin user → encoded magic string on
clipboard), and performDelete into hooks/useUserMgmtActions.ts. The
delete confirmation modal now closes inline in the parent before
delegating to performDelete so the hook stays agnostic of UI state.
UserManagementSection.tsx: 464 → 343 LOC.
* refactor(user-mgmt): extract UserMgmtRow subcomponent
Move the per-user list row (user/admin badges, lib-names blob, magic-
string + delete actions, keyboard activation) into
components/settings/userMgmt/UserMgmtRow.tsx.
UserManagementSection.tsx: 343 → 272 LOC.
* refactor(user-mgmt): extract MagicStringModal subcomponent
Move the per-user magic-string portal modal (password re-set + clipboard
copy of the encoded server-magic-string) into
components/settings/userMgmt/MagicStringModal.tsx. Internal password and
submitting state move into the modal; the parent only owns which user is
targeted.
UserManagementSection.tsx: 272 → 153 LOC.
* refactor(artists): extract helpers + constants
Pull ALL_SENTINEL / ALPHABET / ARTIST_LIST_* row-height estimates,
the ArtistListFlatRow union, CTP_COLORS palette, and the deterministic
nameColor / nameInitial helpers into utils/artistsHelpers.ts.
Artists.tsx: 520 → 496 LOC.
* refactor(artists): extract ArtistAvatars subcomponents
Pull ArtistCardAvatar (300px, grid view) and ArtistRowAvatar (64px, list
view) into components/artists/ArtistAvatars.tsx. Both fall back to a
hashed-Catppuccin monogram when artist images are off or no cover art
is available.
Artists.tsx: 496 → 436 LOC.
* refactor(artists): extract useArtistsFiltering hook
Bundle the letter/text/star filter pipeline, visible-slice memo,
group-by-letter, and the virtualizer flat-rows list into
hooks/useArtistsFiltering.ts. List-view-only outputs short-circuit when
grid view is active.
Artists.tsx: 436 → 386 LOC.
* refactor(artists): extract useArtistsInfiniteScroll hook
Bundle visibleCount + loadingMore state, the sentinel
IntersectionObserver, loadMore callback, and the filter-change reset
into hooks/useArtistsInfiniteScroll.ts. The observer no longer takes
hasMore — the sentinel element only mounts while there is more data,
so the observer attaches/detaches naturally with it.
Artists.tsx: 386 → 370 LOC.
* refactor(artists): extract ArtistsGridView + ArtistsListView
Move the grid card layout to components/artists/ArtistsGridView.tsx and
the dual-path list layout (non-virtualized fallback + virtualized stream)
to components/artists/ArtistsListView.tsx. Both paths now share an
internal ArtistListRow component so click + context-menu behaviour is
identical regardless of which renderer is active.
Artists.tsx: 370 → 233 LOC.
* refactor(album-track-list): extract helpers + types
Pull formatDuration / codecLabel, the COLUMNS / CENTERED_COLS / SORTABLE_COLS
tables, ColKey / SortKey types, and the isSortable type guard into
utils/albumTrackListHelpers.ts. SortKey is re-exported from
AlbumTrackList.tsx so existing imports stay valid.
AlbumTrackList.tsx: 662 → 633 LOC.
* refactor(album-track-list): extract TrackRow subcomponent
Move the memoised tracklist row (~220 LOC including renderCell switch and
mouse handlers) into components/albumTrackList/TrackRow.tsx. It still
subscribes to its own selection + preview state via primitive selectors,
so per-row re-render scope is unchanged.
AlbumTrackList.tsx: 633 → 404 LOC.
* refactor(album-track-list): extract AlbumTrackListMobile subcomponent
Move the narrow-viewport branch (compact tracklist with disc separators
and no column grid) into components/albumTrackList/AlbumTrackListMobile.tsx.
AlbumTrackList.tsx: 404 → 376 LOC.
* refactor(album-track-list): extract TracklistColumnPicker subcomponent
The column visibility dropdown lives outside .tracklist to avoid the
overflow box clipping its menu — pull the wrapper + button + popover into
components/albumTrackList/TracklistColumnPicker.tsx.
AlbumTrackList.tsx: 376 → 347 LOC.
* refactor(album-track-list): extract TracklistHeaderRow subcomponent
The fixed header (sortable + resizable per-column with the bulk-select
toggle on the num cell) moves into
components/albumTrackList/TracklistHeaderRow.tsx, taking 85+ LOC of cell
rendering with it.
AlbumTrackList.tsx: 347 → 254 LOC.
* refactor(album-track-list): extract useAlbumTrackListSelection hook
Pull bulk-selection state (selectedIds-size subscription, shift-range
toggle, click-outside-clear, song-list-change clear) and the drag-start
dispatcher (single vs multi-song drag) into
hooks/useAlbumTrackListSelection.ts.
AlbumTrackList.tsx: 254 → 187 LOC.
* refactor(player-bar): H7 — extract PlaybackTime + RemainingTime + formatTime
The two memoized clock components (which update the DOM imperatively from
the playbackProgress store without re-rendering PlayerBar) move into
components/playerBar/PlaybackClock.tsx. formatTime helper → utils/playerBarHelpers.ts.
PlayerBar.tsx: 802 → 765 LOC.
* refactor(player-bar): H7 — extract PlayerTrackInfo
The cover-art wrap + title/artist marquees + star + last.fm love buttons
move into their own component. The new file uses PlayerState['openContextMenu']
for prop typing so the union literal type carries through.
PlayerBar.tsx: 765 → 674 LOC.
* refactor(player-bar): H7 — extract PlayerTransportControls
Stop/Prev/Play/Next/Repeat buttons (with the preview-ring + schedule-badge
overlays around play/pause) move into PlayerTransportControls.tsx. The
component uses ReturnType<...> on the source hooks to derive its
playPauseBind + scheduleRemaining prop types so the new file stays in lockstep
with usePlaybackDelayPress + usePlaybackScheduleRemaining.
PlayerBar.tsx: 674 → 621 LOC.
* refactor(player-bar): H7 — extract PlayerSeekbarSection
The waveform / radio progress / time-label block moves into its own
component. PlayerSeekbarSection branches on isRadio (AzuraCast progress
bar with elapsed+duration when available; LIVE badge otherwise) vs.
regular track (WaveformSeek or perf-flag fallback + duration ↔ remaining
toggle).
PlayerBar.tsx: 621 → 582 LOC.
* refactor(player-bar): H7 — extract PlayerVolume + PlayerOverflowMenu + 2 hooks
PlayerVolume.tsx is the reusable volume button + slider combo, used in
three layouts (inline, full menu, volume-only menu) — `inputId` /
`sectionModifier` / `wrapModifier` props handle the variants without
class duplication. PlayerOverflowMenu.tsx is the portaled Ellipsis-button
menu that hosts EQ / mini-player buttons + a PlayerVolume instance.
useFloatingPlayerBar owns the docked/floating layout computation
(ResizeObserver on sidebar + queue panel). useUtilityOverflowMenu owns
the overflow detection, menu open/mode state, close-on-outside-click /
Escape, position recompute on resize/scroll, and the wheel-menu timer.
PlayerBar.tsx: 582 → 354 LOC.
* refactor(fullscreen-player): H5 — extract FsLyricsApple + FsLyricsRail + useWordLyricsSync
The two lyrics views become own files under components/fullscreenPlayer/.
Their identical word-sync imperative DOM-update useEffect (only differing in
the .fsa-/.fsr- class prefix) collapses into the shared useWordLyricsSync
hook with a classPrefix arg.
FullscreenPlayer.tsx: 911 → 613 LOC.
* refactor(fullscreen-player): H5 — extract FsArt + FsPortrait + FsSeekbar
The three visual subcomponents move into own files. formatTime moves into
utils/fullscreenPlayerHelpers.ts so FsSeekbar keeps using it.
FullscreenPlayer.tsx: 613 → 421 LOC.
* refactor(fullscreen-player): H5 — extract FsLyricsMenu + FsPlayBtn
The lyrics-settings popover and the isolated play/pause button move into
own files. FullscreenPlayer drops the now-unused lucide-react icons
(Play/Pause/Moon/Sunrise/Music) and the PlaybackDelayModal +
PlaybackScheduleBadge imports — both used only by FsPlayBtn now.
FullscreenPlayer.tsx: 421 → 304 LOC.
* refactor(fullscreen-player): H5 — extract useFsDynamicAccent + useFsArtistPortrait + useFsIdleFade
Pulls three state+effect islands out of FullscreenPlayer:
- useFsDynamicAccent owns the cover-blob fetch + extractCoverColors call
plus the module-level artKey → accent cache that makes same-album song
switches instant.
- useFsArtistPortrait fetches getArtistInfo().largeImageUrl for the right-
side portrait, returning '' until resolved (or when no artistId).
- useFsIdleFade flips isIdle true after 3 s of inactivity, exposes a
throttled mousemove handler, and binds Escape to the provided callback.
FullscreenPlayer.tsx: 304 → 228 LOC.
* refactor(queue-panel): H4 — extract helpers + Save/LoadPlaylistModal
Pure code-move: formatTime, formatQueueReplayGainParts, renderStars and the
DurationMode type → utils/queuePanelHelpers.tsx; the two playlist modals → own
files under components/queuePanel/.
QueuePanel.tsx: 1256 → 1104 LOC.
* refactor(queue-panel): H4 — extract QueueHeader
Pure code-move: the title/count/duration/collapse-button header → its own
component file. No prop or behaviour changes.
QueuePanel.tsx: 1104 → 1004 LOC.
* refactor(queue-panel): H4 — extract QueueCurrentTrack + QueueLufsTargetMenu
The currently-playing track block (cover, info, replay-gain / LUFS badge with
its target-listbox portal) moves into two own files. Pure code-move via prop
plumbing. setLoudnessTargetLufs is typed as LoudnessLufsPreset throughout the
new components.
QueuePanel.tsx: 1004 → 812 LOC.
* refactor(queue-panel): H4 — extract useQueuePanelDrag hook
Moves the psy-drag wiring (hit-test registration, drop-inside dispatch
for song/songs/album/queue_reorder payloads, drop-outside removal) into
its own hook. Drops the dead isRadioDrag variable since the
parsedData.type === 'radio' guard inside onPsyDrop already handles that
case.
QueuePanel.tsx: 812 → 715 LOC.
* refactor(queue-panel): H4 — extract useQueueLufsTgtPopover hook
Pulls the LUFS-target popover open-state, button/menu refs, fixed-position
recompute on open/resize/scroll, and auto-close-when-RG-collapses out of
QueuePanel.
QueuePanel.tsx: 715 → 662 LOC.
* refactor(queue-panel): H4 — extract QueueToolbar
The toolbar-button switch (shuffle/save/load/share/clear/gapless/crossfade/
infinite) and the crossfade popover (with its close-on-outside-click effect)
move into one component. crossfadeBtnRef / crossfadePopoverRef and
showCrossfadePopover state are now component-local — QueuePanel no longer
sees them.
QueuePanel.tsx: 662 → 541 LOC.
* refactor(queue-panel): H4 — extract QueueList
The OverlayScrollArea + queue.map block (with track rows, lucky-mix dice
overlay, and radio/auto-added section dividers) moves into its own
component. PlayerState['contextMenu'] + PlayerState['playTrack'] are
re-used for prop typing, the local StartDrag alias matches the
DragDropContext signature.
QueuePanel.tsx: 541 → 434 LOC.
* refactor(queue-panel): H4 — extract QueueTabBar + useQueueAutoScroll, final cleanup
QueueTabBar is the bottom queue/lyrics/info tab switcher. useQueueAutoScroll
groups the three list-scroll effects (publish scrollTop reader, restore
pending snapshot, scroll next track into view on advance). Drops the dead
toggleQueue and replayGainMode selectors plus the now-unused Play, Radio,
MicVocal, ListMusic, Info imports and OverlayScrollArea.
QueuePanel.tsx: 434 → 383 LOC. Every new file under 400.
* feat(i18n): Add Romanian translation
* feat(i18n): Update Romanian translation to lang file changes
* feat(i18n): Add new Romanian translation entries
* fix(i18n): add settings.languageRo to remaining locale bundles
Romanian was missing from the language picker labels when UI was not en/ro;
add endonym-style names per locale (de/fr/nl/nb/ru/es/zh) for consistency.
* fix(i18n): use Romanian autonym for settings.languageRo everywhere
Match existing language picker convention (e.g. languageDe is Deutsch in
every locale bundle). Replaces UI-language translations of Romanian.
Add scripts/check-css-import-graph.mjs and run it from npm test and
test:coverage so missing relative CSS imports fail CI like Vite/postcss.
Document the step in src/test/README.md; trigger frontend workflow when
the script changes.
The components.css split (PR #657) wrote `result-items.css` to disk, but
.gitignore line 57 (`result-*`) silently filtered it out of `git add -A`.
Local builds worked because the file existed on the splitter's machine;
fresh clones fail with `ENOENT: no such file or directory` when vite
resolves the `@import './result-items.css';` in components/index.css.
Force-adding with `git add -f` keeps the broad `result-*` ignore for
test artifacts intact.
tracks.css (539 LOC) → 8 per-section files in src/styles/tracks/ +
an index.css. Same mechanic as the theme/components/layout splits.
Concatenating reproduces the original byte stream (+1 trailing newline).
Generated via /tmp/split-tracks-css.mjs.
layout.css (3209 LOC) → 29 per-section files in src/styles/layout/ +
an index.css that imports them in original cascade order.
Same mechanic as theme.css + components.css splits: top-level sections
detected by single-dash or 3+ dash header decoration. Concatenating in
@import order reproduces the original byte stream (+1 trailing newline,
cosmetic).
Generated via /tmp/split-layout-css.mjs.
components.css (14205 LOC) → 84 per-section files in src/styles/components/ +
an index.css that imports them in original cascade order.
Same approach as the theme.css split: top-level sections are detected by
single-dash or 3+ dash header decoration (/^\/\* ─(?: |─{2,})/), 2-dash
sub-sections stay inside their parent. Concatenating in @import order
reproduces the original byte stream (+1 trailing newline, cosmetic).
Each section is now self-contained — touching Tracklist, Modal, Hero,
Sidebar, etc. only opens one focused file.
Generated via /tmp/split-components-css.mjs.
theme.css (16138 LOC) → 122 per-section files in src/styles/themes/ +
an index.css that imports them in original cascade order.
Concatenating all files via index.css reproduces the original byte stream
(+1 trailing newline, cosmetic).
Each top-level section header in theme.css (matching /^\/\* ─{3,}/)
becomes its own file, slugged from the header text (or the [data-theme]
selector found in the body when the header was a banner). Pure-separator
headers fold into the previous section so they don't create empty files.
Generated via /tmp/split-theme-css.mjs.
* refactor(internet-radio): G.86.1 — extract RadioToolbar + AlphabetFilterBar
First cut on InternetRadio.tsx: pulled the two header bars into
their own files under src/components/internetRadio/. RadioToolbar
exports the RadioSortBy type alias so the page state and the
toolbar share the same union. AlphabetFilterBar owns the
A-Z + # key list internally.
Pure code move.
* refactor(internet-radio): G.86.2 — extract RadioCard
Pulled the single radio-station card component (cover, live overlay,
play/delete buttons, name + edit/favourite/homepage chip row) into
its own file. It owns its drag source + the psy-drop listener that
fires onDropOnto with the cursor-side (before/after).
Pure code move.
* refactor(internet-radio): G.86.3 — extract RadioEditModal
Pulled the create/edit-station modal (cover preview + change/remove,
name + stream URL + homepage URL fields, save spinner) into its own
file. station=null means "create new". Pure code move.
* refactor(internet-radio): G.86.4 — extract RadioDirectoryModal
Pulled the radio-browser directory modal (top-stations preload,
debounced search, IntersectionObserver-driven pagination, favicon
+ add-station flow with cover upload from favicon URL) into its
own file. Pure code move.
InternetRadio.tsx is now 299 LOC — every subcomponent lives in
src/components/internetRadio/.
Four-cut cluster closing out the major ArtistDetail extraction.
707 → 339 LOC (−368).
ArtistDetailHero — the full hero header: back button, lightbox
trigger, avatar with hover upload overlay + camera/loader icon +
hidden file input, glow effect from extractCoverColors onLoad,
title + album count, entity-rating row, Last.fm + Wikipedia +
favourite link row, and the action button strip (play all,
shuffle, radio, share, offline cache with progress / done state).
Subscribes to useOfflineStore / useOfflineJobStore / useAuthStore
directly so the page doesn't have to thread bulk-progress through.
ArtistDetailTopTracks — the four-column tracklist with each row's
inline play-next + preview ring + track cover thumbnail + click
into playTopSongWithContinuation. Subscribes to playerStore /
previewStore / useOrbitSongRowBehavior directly.
ArtistDetailSimilarArtists — section header (with show-more toggle
on mobile), loading spinner, and the chip list (using
serverSimilarArtists vs. similarArtists depending on which path
fed it).
runArtistDetailActions — four parameterized async actions:
runArtistEntityRating (with full / track_only fallback +
saveFailed toast), runArtistToggleStar (optimistic state + revert
on error), runArtistShare (copy link + success / failure toast),
runArtistImageUpload (upload + invalidate cover-art cache + bump
revision).
ArtistDetail drops the inline definitions; formatDuration moves
into the TopTracks component. Pure code move otherwise.
Five-cut cluster opening the ArtistDetail refactor. 944 → 631 LOC
(−313).
artistDetailHelpers — formatDuration (M:SS) + sanitizeHtml (strip
script/style/iframe/etc tags + onXxx + javascript: / data: hrefs).
ArtistSuggestionTrackCover — tiny CachedImage wrapper for the
32×32 cover thumbnail in the suggestions tracklist.
useArtistDetailData — owns the page's three primary fetch effects:
getArtist + getTopSongs on artist id change, getArtistInfo on id +
audiomuseNavidromeEnabled change, and the background "Also Featured
On" search that derives albums from search results not in the
artist's own album set. Exposes artist / setArtist / albums /
topSongs / info / featuredAlbums / loading flags + isStarred for
the star button.
useArtistSimilarArtists — owns the two parallel similar-artist
effects (Last.fm primary path when AudioMuse is off; Last.fm
fallback when AudioMuse is on but returned nothing) plus the
audiomuse-positive-result reset. Returns { similarArtists,
similarLoading }.
runArtistDetailPlay — three play orchestrators that share the
fetchAllTracks helper: runArtistDetailPlayAll, runArtistDetailShuffle,
runArtistDetailStartRadio (with the no-radio fallback alert). All
take deps objects so the page just delegates state setters.
ArtistDetail drops the now-unused direct search / getArtistInfo /
getTopSongs / getSimilarSongs2 / getArtist / lastfmGetSimilarArtists
imports. Pure code move otherwise.
Three-cut cluster pulling the dominant songs section out of
Favorites.tsx. 645 → 217 LOC (−428).
FavoritesSongsSectionHeader — the section above the tracklist:
title with showing-N-of-M indicator, Play-All / Enqueue-All
buttons, filter toggle, clear-all button (resets artist + genre +
year + sort), filters panel with GenreFilterBar + dual-range
year sliders, and the "clear artist filter" button when an
artist filter is active. Takes the minYear / currentYear
constants explicitly so the page still owns them.
FavoritesSongsTracklist — the tracklist below: bulk-action bar
(N selected + Add-to-playlist submenu + clear), column-visibility
picker, sortable column header, song rows (selection check + bulk
toggle, currentTrack highlight, inline play + preview buttons in
the title cell, artist/album link cells, genre/format/duration/
rating cells, remove button), and the no-filter-results empty
state. Subscribes to playerStore / previewStore / selectionStore /
useDragDrop / useOrbitSongRowBehavior directly.
useFavoritesSelection — owns lastSelectedIdxRef and the two
useEffects (clear-on-songs-change + clear-on-click-outside) plus
the toggleSelect callback with shift-range support.
Favorites drops the inline definitions and removes the now-unused
direct useRef / useCallback declarations. Pure code move
otherwise.
Four-cut cluster opening the Favorites refactor. 1018 → 643 LOC
(−375).
TopFavoriteArtists — TopFavoriteArtistsRow (the horizontal-scroll
section with chevron nav buttons and resize-driven scroll-state)
plus the private TopFavoriteArtistCard with the cached avatar
image and selected-outline styling. Exports the
TopFavoriteArtist row-data shape.
RadioFavorites — RadioStationRow (same horizontal-scroll pattern
as the artists row) plus the private RadioFavCard with cover or
Cast-icon fallback, live-radio badge overlay when active, and an
unfavorite heart button.
useFavoritesData — owns the four data states (albums, artists,
songs, radioStations) + loading + the load-on-mount effect (calls
getStarred + reads radio favorites from localStorage + fetches
matching stations). Computes topFavoriteArtists memo (counts
favorited songs by artist, top 12). Exports unfavoriteStation
(removes from state + persists to localStorage).
useFavoritesSongFiltering — owns the filtering pipeline (drops
unfavorited, applies artist / genre / year-range filters) and
the three-state sort (asc → desc → reset). Returns
filteredSongs / visibleSongs plus handleSortClick /
getSortIndicator. Hook file uses .tsx because getSortIndicator
returns ArrowUp / ArrowDown JSX.
Favorites drops the inline definitions plus the now-unused direct
imports (getInternetRadioStations, getStarred, buildCoverArtUrl /
coverArtCacheKey, useAuthStore, Users / ArrowUp / ArrowDown
icons). Pure code move otherwise.
Three-cut cluster closing out the Playlists refactor. 516 → 273 LOC
(−243).
runPlaylistsActions — runPlaylistDelete (two-click confirm with
tooltip re-trigger), runPlaylistDeleteSelected (filters by
deletable, refreshes store, fires per-row error toasts), and
runPlaylistMergeSelected (collects unique songs across selected
playlists into the target, updatePlaylist + touchPlaylist + total
count toast). Each takes a deps object so all state-setters /
callbacks are explicit.
PlaylistsHeader — title row + creation controls (inline name
input with Enter / Escape handling, "New playlist" button,
"New smart" button gated on isNavidromeServer) + bulk delete
button + selection-mode toggle. The selection-mode title swaps
between t('playlists.title') and t('playlists.selectionCount').
PlaylistCard — full single-card render: cover area (smart-playlist
2×2 collage / cover image / fallback ListMusic icon + pending
clock badge), hover-only edit + delete buttons (delete with
two-click confirm), selection check overlay, play overlay button
with spinner state, and the info row (smart-playlist sparkle +
display name + song count + duration). Subscribes to
playerStore.openContextMenu directly.
Playlists drops the inline definitions + the now-unused direct
imports (deletePlaylist / updatePlaylist, buildCoverArtUrl /
coverArtCacheKey, CachedImage, StarRating, the cover image
helpers, most lucide icons, useMemo). Pure code move otherwise.
Four-cut cluster pulling the Smart-playlist machinery out of
Playlists.tsx. 763 → 480 LOC (−283).
runPlaylistsOpenSmartEditor — open-existing flow: tries
ndGetSmartPlaylist first (freshest rules), falls back to
ndListSmartPlaylists if that fails or doesn't return the playlist;
populates the editor with parsed filters or a name-only seed for
shared / migrated edge cases; degrades gracefully with a warning
toast if everything fails.
runPlaylistsSaveSmart — create / update flow: dedupes the base
name against existing playlists by appending `-2`, `-3` … on
creation (skipped on edit); builds rules via
buildSmartRulesPayload; calls ndCreate or ndUpdate; tracks the
result in pendingSmart so the polling hook can observe rules
processing on the server.
usePendingSmartPolling — every 10 s polls fetchPlaylists +
getPlaylist for each pending item; rehydrates the playlist store
when the detail endpoint reports fresh metadata before the list
endpoint catches up; stops polling an item when it has songs +
its cover changed (or after ~3 minutes hard timeout).
PlaylistsSmartEditor — the full smart-editor card (three
sections: Basic / Genres / Years + Filters). Owns no state of
its own; every input is a controlled component against
smartFilters via setSmartFilters. The cancel button still resets
through the page's setters.
Playlists drops the inline definitions plus its direct
'../api/navidromeSmart' import (now consumed inside the two
orchestrators). Pure code move otherwise.
Four-cut cluster opening the Playlists refactor. 1039 → 763 LOC
(−276).
playlistsSmart — full smart-playlist module: SMART_PREFIX /
LIMIT_MAX / YEAR_MIN / YEAR_MAX constants, GenreMode / YearMode /
SmartFilters / PendingSmartPlaylist / NdSmartRuleNode types,
defaultSmartFilters seed, clampYear / isSmartPlaylistName /
displayPlaylistName / asRecord helpers, parseSmartRulesToFilters
(the Navidrome JSON rule walker), and buildSmartRulesPayload (the
reverse — page-state → Navidrome JSON). The payload builder
becomes parameterized on the filters object so it lives outside
the component.
PlaylistCoverImages — two tiny CachedImage wrappers
(PlaylistSmartCoverCell for the 200 px collage cells,
PlaylistCardMainCover for the 256 px main card cover).
useSmartCoverCollage — replaces the inline useEffect that builds
the 2×2 cover collage for each smart playlist (pulls playlist
tracks, filters to active library scope, collects up to four
unique cover-art ids). Returns the per-playlist id map and
re-fetches on playlist list change or library filter version bump.
usePlaylistsLibraryScopeCounts — replaces the inline useEffect
that recomputes per-playlist song count + total duration under
the current library scope. Chunked into batches of four parallel
fetches.
Playlists drops the inline definitions; pure code move otherwise.
Two-cut cluster pulling the main layout columns out of
DeviceSync.tsx. 511 → 233 LOC (−278). DeviceSync is now mostly
glue: state hooks, hook calls, action wrappers, and a flat tree of
five layout components.
DeviceSyncBrowserPanel — left column. Owns the tabs row
(playlists / albums / artists with icons), the search input with
the "Live search" badge on the albums tab, and the result list:
loading spinner, "Random albums" section label, playlist /
album / artist rows with their BrowserRow leaf component, and the
expand-an-artist tree (loading state, chevron, child album rows
with indent). filteredPlaylists / filteredArtists memos move into
the panel since only the row mapping consumes them.
DeviceSyncDevicePanel — right column. Owns the header (title +
scanning spinner + sync action button with three label variants
+ "Delete from device" button), the status badges row
(synced / pending / deletion), the source list with checkbox /
type / status icon / per-row action (mark-for-deletion /
remove-source / undo-deletion), and the bottom progress strip
(running / cancelled / done) with their dismiss / cancel
buttons. invoke('cancel_device_sync') stays in the panel since
it's a panel-local action.
DeviceSync drops the now-unused invoke / BrowserRow / useMemo
imports (filteredPlaylists/Artists moved into the panel). Pure
code move otherwise.
Three-cut cluster pulling the chrome out of DeviceSync.tsx. 739 →
501 LOC (−238).
DeviceSyncHeader — title row, fixed-scheme info block (with the
"Reorganize existing files…" migrate button), and the drive picker
row (manual folder picker, refresh, CustomSelect over detected
drives or no-drives fallback, drive metadata line).
DeviceSyncPreSyncModal — the modal that opens before sync execution:
loading spinner while calculate_sync_payload runs, then the
delta-stats grid (add count + bytes, delete count + bytes, net
change, available space) with the space-warning when add exceeds
available + del, plus the cancel / proceed footer.
DeviceSyncMigrationModal — the migrate-existing-files modal with
its five-phase state machine (loading / nothing / preview /
executing / done): preview lists rename count + unchanged count
+ collision warning + old-template note; done shows ok / failed
counts + a collapsible error list capped at 50 entries.
DeviceSync drops the inline JSX + the now-unused HardDriveUpload /
FolderOpen / Usb / RefreshCw / Loader2 (partially) icon imports
that only the header used. Pure code move otherwise.
Four-cut cluster pulling the remaining lifecycle code out of
DeviceSync.tsx. 928 → 638 LOC (−290).
useDeviceSyncBrowser — playlists / randomAlbums / artists state +
their three loaders + the tab-switch useEffect that lazy-loads on
first visit + the 300 ms debounced album-search useEffect + the
expandedArtistIds / artistAlbumsMap / loadingArtistIds state with
toggleArtistExpand. Takes activeTab + search + a resetSearch
callback (so the tab-switch effect can clear the search input the
page still owns).
useDeviceSyncDeviceScan — scanDevice useCallback + the on-mount
useEffect + the auto-import-manifest useEffect (with the
manifestImportedRef gate so it only fires once per drive plug-in)
+ the clean-on-unplug useEffect that clears deviceFilePaths and
resets the import flag.
useDeviceSyncJobEvents — the device:sync:progress and
device:sync:complete event listeners. Complete handler dispatches
the toast, writes the manifest, generates per-playlist m3u8 files
(through fetchTracksForSource + trackToSyncInfo), and triggers
scanDevice. Cancelled state is preserved by re-calling
useDeviceSyncJobStore.cancel() after complete().
runDeviceSyncChooseFolder — the openDialog → setTargetDir →
optional manifest auto-import → scanDevice timer flow.
DeviceSync drops every direct import that those hooks now own
(getPlaylists, getArtists, getArtist, getAlbumList, searchSubsonic,
listen, openDialog, useEffect, useRef, SubsonicPlaylist /
SubsonicArtist / SubsonicAlbum type imports). Pure code move
otherwise — no behaviour change.
Four-cut cluster pulling the orchestrators out of DeviceSync.tsx.
1179 → 905 LOC (−274).
useDeviceSyncDrives — drives state + drivesLoading + refreshDrives
callback + the 5 s polling useEffect + the activeDrive memo that
matches targetDir against any detected drive's mount_point.
Returns { drives, drivesLoading, activeDrive, driveDetected,
refreshDrives }.
useDeviceSyncSourceStatuses — owns sourcePathsMap state + the
useEffect that computes per-source paths through compute_sync_paths
(parallel for all sources, with the cancellation guard), and the
derived sourceStatuses Map keyed on 'synced' / 'pending' /
'deletion'.
runDeviceSyncMigration — runDeviceSyncMigrationPreview (read v1
manifest's filenameTemplate, fetch album-source tracks, compute
new paths via Rust + old paths via JS legacy template, diff into
pairs + collisions + unchanged) and runDeviceSyncMigrationExecute
(invoke rename_device_files, bump manifest to v2, rescan device).
Exports MigrationPhase / MigrationPair / MigrationResult types so
the page state stays typed.
runDeviceSyncExecution — runDeviceSyncSummaryPrompt (input
validation + invoke calculate_sync_payload through the subsonic
client) and runDeviceSyncExecute (delete pending sources, re-write
playlist m3u8 even when nothing to download, fire sync_batch_to_device
with the right toast variants on space / mount / generic errors).
SyncDelta type moves with it.
DeviceSync drops the inline definitions; closeMigration stays
inline (six lines, no real win extracting it). Pure code move
otherwise — no behaviour change.
Four-cut cluster opening the DeviceSync refactor. 1289 → 1186 LOC
(−103).
deviceSyncHelpers — uuid, formatBytes, trackToSyncInfo (with the
albumArtist-fallback-to-artist logic and the optional playlist
context the Rust sync command consumes), plus the SourceTab /
SyncStatus / RemovableDrive / SyncTrackMaybePlaylist types.
deviceSyncLegacyTemplate — sanitizeComponent (matches Rust's
sanitize_path_component) + OldTemplateTrack + applyLegacyTemplate.
Lives apart from the general helpers because it's only used by the
migration-preview flow and pulls in IS_WINDOWS for path separator.
fetchTracksForSource — single async helper that loads the songs for
a DeviceSyncSource (playlist / album / artist). Artist sources fan
out into parallel getAlbum requests (Navidrome handles them
concurrently; the old sequential loop was a ~7 s blocker on
50-album artists).
BrowserRow — small button row component used by the source-picker
list (playlists / albums / artists tabs).
DeviceSync drops the inline definitions plus the direct getAlbum /
getPlaylist / getArtist imports that only fetchTracksForSource
needed. Pure code move — no behaviour change.
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.
Five-cut cluster pulling the dashboard subcards out of NowPlaying.tsx.
1119 → 711 LOC (−408). Each card was already a top-level
React.memo'd block with a clean prop interface, so this is straight
file-per-card extraction with no behaviour change.
Hero — full hero strip: cover image, title, artist/album/year/age
sub, format/codec/sample-rate/bit-depth/duration badges with the
Hi-Res chip, the favourite + Last.fm-love + lyrics action buttons,
play-count line, and the Last.fm track + artist stats rows (with
their per-row `you played N×` highlight). renderStars (5-star
inline indicator) moves inline as a private helper since only Hero
calls it.
ArtistCard — about-this-artist card: optional hero image (filtered
through isRealArtistImage so we don't render the well-known
"2a96…" placeholder), name, sanitized + clamp-with-Read-more bio,
similar-artist chip row. Owns its bioExpanded / bioOverflows state
and the useLayoutEffect that measures overflow.
AlbumCard — from-this-album card: meta line (year / track position /
total duration / play count), sliding-window tracklist anchored on
the current track (top 10 by default, or the 10 ending at the
running track if it's beyond position 10), and the show-all toggle.
TopSongsCard — top-songs-by-artist card: rank-ordered list (max 8),
each row clicks into playerStore via the onPlay callback.
CreditsCard — contributor / song-info card: role-grouped list with
i18n role label lookup (falls back to the raw role string).
NowPlaying drops the now-unused imports (useLayoutEffect, LastfmIcon,
Star, MicVocal, Heart, Headphones, TrendingUp from lucide,
sanitizeHtml + isRealArtistImage + formatTotalDuration from
nowPlayingHelpers) plus the inline renderStars helper. Pure code
move otherwise.
