Re-exporting the store singletons (fontCatalogStore, fontLifecycleManager,
FontsByIdsStore) through entities/Font/index.ts meant every consumer of the
barrel eager-instantiated stores and pulled @tanstack/query-core — in dev,
test, and as retained code. Drop the store re-export from the top barrel;
keep the pure surface (types, constants, domain, lib, ui) there for
convenience. Consumers that need stores import $entities/Font/model.
Aligns with the BaseQueryStore carve-out: barrel by default, segment path
when it would drag a heavy or side-effectful dependency.
FetchFontsByIds was data-access for the Font aggregate wearing a feature
costume: a single FontsByIdsStore (BaseQueryStore over Font's proxy API),
no UI, consumed only by comparisonStore. Move it beside fontCatalogStore
in the Font entity, collapse its deep $entities/Font imports to relative
paths, expose via the Font public API, and delete the feature slice.
The seed-defaults effect fired whenever fontA/fontB were still
undefined, including the window between constructor reading storage
and the per-id batch resolving. On a slow batch or fast catalog the
effect clobbered storage with catalog[0]/catalog[N-1], losing the
user's pick on reload.
Now bails when storage already holds IDs, and reads storage via
untrack so per-font selection writes don't re-trigger the effect.
Adds a deterministic regression test that controls catalog/batch
ordering via mockImplementation timing.
- Use existing MULTIPLIER_S/M/L from \$entities/Font in SliderArea instead
of inlining the 0.5/0.75/1 literals (constants already existed but were
duplicated at the call site).
- Centralize API base URL in \$shared/api/endpoints.ts (was duplicated
between proxyFonts and FilterAndSortFonts filters api).
- Promote every 'glyphdiff:...' localStorage key to a named module-level
STORAGE_KEY constant. Test files now import the source constant rather
than redeclaring it (eliminates silent-typo divergence risk).
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.
The byId font fetch was a verb-oriented capability with a single
consumer driven by a feature need (materializing comparison picks).
That shape belongs at the feature layer, not on the entity.
Move:
- entities/Font/model/store/batchFontStore -> features/FetchFontsByIds/model/store/fontsByIdsStore
- Class BatchFontStore -> FontsByIdsStore
entities/Font retains the transport primitives (fetchFontsByIds,
seedFontCache) and the keyspace (fontKeys); the feature wraps them in
the reactive store. comparisonStore now imports FontsByIdsStore from
the new feature. The proxy API is imported via direct path so vi.spyOn
on the source module still observes the call.
Structural:
- Merge factory + singleton from lib/settingsManager and model/state into
one model/store/typographySettingsStore/ slice
- Drop now-empty lib/ and model/state/ directories
Semantic:
- Rename feature SetupFont -> AdjustTypography (the feature owns
continuous typography adjustment, not one-time font setup)
- Drop "Manager" from TypographySettingsManager -> TypographySettingsStore
(class + factory); singleton typographySettingsStore unchanged
All consumers (Character, Line, SampleList, SliderArea, FontSampler,
comparisonStore) updated. Public barrel signature changed: now exports
createTypographySettingsStore and type TypographySettingsStore.
Replace hand-rolled async fetching (fetchFontsByIds + isRestoring flag)
with BatchFontStore backed by TanStack Query. Three reactive effects
handle batch sync, CSS font loading, and default-font fallback.
isLoading now derives from batchStore.isLoading + fontsReady.
