Description

Updates the dashboard page to use a single page request per row, and swaps the book cards to the new component.

Linked Issue

Fixes #2598

Changes

  • Changes dashboard from the legacy to the new book card, which supports the paginated book type. Updated presentation and loading logic to match that of the book browser page.
  • Removed all old client side sorting and dashboard query code. Replaced with a plain book query page request for each row.
  • Deleted dead SortService and other unused client side data handling code, including i18n strings.

Manual Testing Steps

Use dashboard with various options, sort types, check book progress, etc.

Screenshots (Optional)

Screenshot 2026-09-12 at 17 34 04

Additional Context (Optional)

There are three custom sort options the client side dashboard used (file path, file name, file format) that the browser / endpoints don't use. I've left to fallback to title sort rather than break these or throw an error.

AI Disclosure

Cleaned up dead code and checked implementation vs book browser with codex.

  • src/content/docs/start/dashboard.mdx:27 says scrollers are hidden when empty. The new dashboard renders explicit empty/loading/error states for configured scrollers, so this statement is likely outdated. [::grimmory-tools/grimmory-docs::]

Walkthrough

The dashboard now uses BookQueryService with scroller-specific query helpers. DashboardScrollerComponent owns loading, error, empty, and book states. Legacy dashboard book selection, sorting, and card rendering were removed. Cover readiness timing was updated.

Changes

Dashboard query migration

Layer / File(s) Summary
Dashboard row query construction
frontend/src/app/features/dashboard/dashboard-row-query.ts, frontend/src/app/features/dashboard/dashboard-row-query.spec.ts
Added scroller-specific query parameters, progress-file selection, row sizing, magic-shelf sorting, and tests for read and listening rows.
Query-driven dashboard scroller
frontend/src/app/features/dashboard/components/dashboard-scroller/*
The scroller now accepts ScrollerConfig, queries books internally, manages explicit view states, renders new book cards, and supports retry, navigation, menus, skeletons, and artwork reveal behavior.
Main dashboard integration
frontend/src/app/features/dashboard/components/main-dashboard/*, frontend/src/app/features/dashboard/services/dashboard-book.service.ts
The main dashboard passes complete scroller configurations, removes legacy book-service wiring, and deletes DashboardBookService.
Dashboard sorting surface cleanup
frontend/src/app/features/settings/view-preferences-parent/dashboard-preferences/dashboard-preferences.component.ts, frontend/src/app/features/book/service/*
Removed file-based dashboard sort options and deleted SortService with its unit tests.
Cover readiness timing
frontend/src/app/shared/components/cover/cover.component.ts
Preview renders mark the cover ready immediately. Hidden-image renders defer readiness through two animation frames.

The dashboard works with the new query behavior, but user-facing documentation still describes the old empty-scroller behavior and should be updated.

- Around line 52-53: Update rowQuery and the dashboardRowBooks flow so a null
dashboardRowQueryParams() cannot bind BookQueryService.page() to a fallback
query key or expose cached books. Use skipToken for the disabled query or ensure
rowBooks() returns an empty array when params() is null, preserving normal book
loading for valid parameters.

- Line 30: Update the dashboard documentation associated with the
enabledScrollers loop to state that enabled scrollers still render when their
queries return no books and display an empty-state message; remove or replace
any wording claiming empty scrollers are hidden.

In `@frontend/src/app/features/dashboard/dashboard-row-query.spec.ts`:
- Around line 45-50: The dashboard row query specs currently lack coverage for
dashboardRowQueryParams. Add tests covering LATEST_ADDED, RANDOM, and
MAGIC_SHELF, verifying facets, sort, size, missing magicShelfId handling, and
sort fallback, using the existing query-builder and DashboardScrollerComponent
test patterns.

Learning: When reviewing code in the Grimmory frontend (Angular), prefer modern Angular patterns. Specifically: (1) Prefer `DestroyRef` with `takeUntilDestroyed(destroyRef)` for teardown in Angular v16+ instead of manually tracking `Subscription` arrays and calling `unsubscribe()` in `ngOnDestroy()`. (2) Prefer `inject()` for dependency injection over constructor injection where appropriate. (3) Prefer Angular signals (e.g., `signal`, `computed`) over `BehaviorSubject`/`Observable` for state where signals/computed values fit the use case. Flag older patterns when they can be replaced with these modern equivalents without changing behavior.
