# Workspace Dashboard This document records the current dashboard implementation inside the workspace shell. Related: - [Workspace Shell](./workspace-shell.md) ## Summary - The dashboard is the default `/workspace` landing page. - It is a **rail-based** content surface (Netflix / Apple TV pattern), not a customizable widget grid. - Layout order is static and curated — there is no edit mode, drag-drop, or size stepper. Each rail has a persisted show/hide toggle (`Settings.dashboardRails`, `DashboardRailsSettings` in `libs/shared/interfaces/src/lib/settings.interface.ts`, surfaced under Settings → Dashboard); every template rail is gated by `dashboardRails().`. Rails additionally auto-hide when empty. - First-run users see the shared welcome empty-state with a single primary CTA to add their first playlist. Core implementation: 1. `libs/workspace/dashboard/feature/src/lib/rails/workspace-dashboard-rails.component.ts` — the page-level facade. 2. `libs/workspace/dashboard/feature/src/lib/rails/dashboard-rail.component.ts` — the reusable horizontal rail. 3. `libs/workspace/dashboard/data-access/src/lib/dashboard-data.service.ts` — data aggregation (recent items, favorites, playlist stats). Shared across rails. 4. `libs/playlist/shared/ui/src/lib/recent-playlists/empty-state/empty-state.component.ts` — reused welcome state with the primary "Add your first playlist" CTA. ## Page Structure ``` ┌─────────────────────────────────────────────────────────────────────┐ │ Hero — Continue Watching (most recent item) │ ├─────────────────────────────────────────────────────────────────────┤ │ Continue Watching · See all → │ │ [poster][poster][poster][poster] →→ │ ├─────────────────────────────────────────────────────────────────────┤ │ Live now on your favorites · See all → │ │ [channel][channel][channel][channel] →→ │ ├─────────────────────────────────────────────────────────────────────┤ │ Recently watched live TV · See all → │ │ [channel][channel][channel][channel] →→ │ ├─────────────────────────────────────────────────────────────────────┤ │ Favorite movies & series · See all → │ │ [poster][poster][poster][poster] →→ │ ├─────────────────────────────────────────────────────────────────────┤ │ Recently Used Sources · See all → │ │ [tile][tile][tile][tile] →→ │ ├─────────────────────────────────────────────────────────────────────┤ │ Recently Added on Xtream (aggregated across providers) │ │ [poster][poster][poster] →→ │ ├─────────────────────────────────────────────────────────────────────┤ │ Because you watched X (TMDB, opt-in, Electron-only) │ │ [poster][poster][poster] →→ │ ├─────────────────────────────────────────────────────────────────────┤ │ Trending this week (TMDB, opt-in, Electron-only) │ │ [poster][poster][poster] →→ │ └─────────────────────────────────────────────────────────────────────┘ ``` Render rules: 1. Dashboard rails render independently as their data sources resolve. The page no longer uses `dashboardReady()` as a page-wide skeleton gate. Initial hero/recent/favorites loading states render scoped skeletons so one slow rail does not hide already available content. 2. `hasPlaylists() === false` → render `` full-bleed. All rails and the hero are skipped. 3. `hero()` = `globalRecentItems()[0]`. If present, render the hero panel. 4. Each rail is emitted via `@if (cards.length > 0)`. Empty rails are hidden — there is no "empty widget" placeholder. 5. The continue-watching hero prefers a stored Xtream `backdrop_url`; when it is missing the UI falls back to a blurred poster treatment instead of showing a flat panel. 6. Live favorites are promoted into their own live rail; movie/series favorites render in a separate `Favorite movies & series` rail (`favoriteMoviesAndSeriesCards`, `data-test-id="dashboard-favorite-vod-rail"`, mapped from `globalFavoriteItems()` filtered to movie/series). Full mixed favorites management stays on `/workspace/global-favorites`. 7. The live favorites rail keeps its scoped skeleton until the initial global favorites load has completed for both Xtream-backed and playlist-backed favorites. This avoids first-paint partial counts such as a single Stalker favorite appearing before M3U favorites finish resolving. ## Rail Contract `DashboardRailComponent` is purely presentational: 1. Inputs: `label`, `items: DashboardRailCard[]`, optional `seeAllLink`, optional `aspectRatio` (default `'2 / 3'`), optional `testId`. 2. Behavior: horizontal flex track with `scroll-snap-type: x mandatory`. 3. Chevron buttons fade in on hover (desktop only via `@media (hover: none)`). 4. Cards are keyboard-focusable router links; `scroll-snap-align: start` means arrow-key nav lands on card boundaries. 5. Image handling: `loading="lazy"`, `decoding="async"`, fallback icon tile when `imageUrl` is missing or `error` fires. 6. Dashboard hero, rail containers, rail cards, and "Manage all" links expose stable `data-test-id` hooks. Treat these as the supported Electron E2E selector surface; do not target internal CSS class names. ## Data Flow 1. `WorkspaceDashboardRailsComponent` injects `DashboardDataService`. 2. It derives the dashboard surface via `computed()`: 1. `hero` — first item of `globalRecentItems()`. 2. `continueWatchingCards` — maps `globalRecentVodItems()` to movie/series cover cards. Portal playback positions are bulk-loaded per playlist so hero and cards can show progress, remaining time, and series season/ episode badges. Whether an item is looked up as a movie (one `vod` row) or a series (episode rows under the parent id) is its WATCH kind, `resolvePortalActivityWatchKind`, not its routing `type`. The shape that needs the distinction is a Stalker embedded-VOD row: its stored entry carries a `series[]` episode array but no `is_series` flag, so `extractStalkerItemType` reports `movie` (deliberately — the item belongs in the VOD catalog) while its progress lives in episode rows. The mappers give both it and a lazy Ministra `is_series` row (already typed `series`) `watch_kind: 'series'`. Series lookup uses keyed maps for both direct episode ids and parent series ids; card renders must not scan the full playback-position map. The badge uses saved `seasonNumber` / `episodeNumber` metadata and does not infer it from provider payloads; legacy rows without that metadata remain badge-less until replay. Dashboard-originated Xtream and Stalker series clicks also carry that exact episode target through the global-recent inline-detail handoff. Once the series metadata and playback positions load, the detail player consumes the target once and resumes the saved episode. Opening the same item normally from the global recent grid remains a detail-only action. Continue Watching cards carry no provider/content-kind subtitle: their meta row is the S·E chip plus a "N min left" label (`remainingLabel`, from `formatRemainingLabel`), and the row is not rendered when both are absent. The hero subtitle is the source name alone, through `playlistDisplayLabel`. 3. `liveFavoriteCardsEnriched` and `recentLiveCardsEnriched` — two independent rails (`dashboard-live-favorites-rail` and `dashboard-recent-live-rail`); there is no fallback from one to the other. M3U cards carry an `epg_lookup_key` using the app-wide XMLTV fallback order (`tvg-id` -> `tvg-name` -> channel name); EPG enrichment must use that key before falling back to the card title. Both rails are enriched by `DashboardLiveEpgPresenter`, the one component-provided facade for live EPG: it owns the XMLTV lookup described under "Scoped lookups" in `m3u-playlist-module.md`, forwards everything portal-shaped to `DashboardPortalLiveEpgPresenter`, and `enrich()` returns the cards with their "now on air" row filled in. Xtream and Stalker cards have no XMLTV key of their own; their "now on air" line comes from the portal, **lazily and per card**: - `buildDashboardPortalLiveEpgEntry` (dashboard data-access) turns a live `PortalActivityItem` into the `UnifiedCollectionItem` the collection pages hand `StreamResolverService.loadEpgForItems`, keyed by the collection uid — favourites and recent rows of one channel share the answer. Radio rows and rows without a usable provider id get no entry. Cards carry that key as `liveEpgSourceKey`. - `lib-dashboard-rail` reports the cards inside its track viewport (plus ~one card of `rootMargin`) through `visibleCardsChanged`, from an `IntersectionObserver` rooted at the track; without the API every card counts as visible. Cards that leave the list are reported gone at once. - `DashboardPortalLiveEpgPresenter` (component-provided) unions the visible keys of both rails with the pinned hero key and calls `DashboardPortalLiveEpgService.sync()` with exactly those entries — on every change, on the 30 s tick, and on a display-offset change. It is reached through `DashboardLiveEpgPresenter`, which derives the portal rows itself from the enabled rails and pins the hero, so the page component only forwards what a rail can see. The queue lives in the root service, so leaving the dashboard hands the wanted set back (`sync([])` on destroy); otherwise the queue would keep asking for cards on a page that is gone. - `DashboardPortalLiveEpgService` (root) owns the queue: at most two requests in flight, 200 ms between starts (the numbers `EpgQueueService` proved against real panels), one card per request, each answer published the moment it lands in `programs`, so the page never waits and a slow portal delays no other card. Only wanted keys are dequeued, so a card scrolled past before its turn is never requested. A programme lives 60 s; a programme that ended is asked again, but not within 30 s of the last answer (a portal may keep returning the stale row). An answer with **no** programme lives only 30 s, because the resolver reports a failed portal and a guide-less channel identically (it files per-channel failures as `null`), so there is no failure cooldown to keep and the short TTL is what lets an outage recover on the next tick. - Every answer is "at the provider clock" and against one XMLTV source set. A request captures both the display offset and `EpgSourceSettingsService.revision()` — the same fence `EpgService.guard()` uses — and a completion whose either fact moved is discarded and requeued instead of published. That requeue has to happen in the completion: while the key is in flight the retire pass cannot queue a replacement, and without it the pre-change answer would be trusted for a full TTL (the repo's late-result invalidation contract). - Desktop only in practice: the shared collection resolver is gated on the local XMLTV bridge (`supportsProgramLookup`) and answers nothing without it, so `sync()` returns immediately in the PWA rather than filing an empty answer for every card. Lifting that gate for portal lookups would change the collection pages too and is deliberately out of scope here. - `DashboardLiveEpgPresenter.enrich()` prefers the portal answer, falls back to the XMLTV title match when the portal said "nothing on air", and marks a card `nowPlayingState: 'pending'` only before its FIRST answer — the channel layout then shows a shimmer placeholder in the programme slot; a refresh keeps the previous answer on screen. 4. `xtreamRecentlyAddedCards` — maps `xtreamRecentlyAddedItems()` to rail cards. Aggregates newly added VOD and series across *all* Xtream playlists via `DashboardDataService.reloadXtreamRecentlyAddedItems()`, which calls `getGlobalRecentlyAdded('all', limit, 'xtream')` with the DB-level `playlists.type = 'xtream'` filter. The rail is Electron-only (PWA returns `[]`) and auto-hides when empty, so users without Xtream playlists never see it. Cards carry the source name as their subtitle (`playlistDisplayLabel`) so users can tell where each item was added; the content kind is not repeated on every card. Driven by an effect that re-runs whenever the Xtream playlist count changes, but the first run waits for `globalFavoritesLoaded()` so the slower recently-added DB query does not block the live favorites rail on startup. 5. `recommendationCards` / `trendingCards` — the two TMDB rails. Both need the TMDB opt-in AND the Electron DB worker that answers `DB_MATCH_TITLES` (each is hidden in the PWA), and both load after `globalFavoritesLoaded()` so the batched title match never competes for the worker at startup. `recommendationCards` is seeded from recently watched movies/series and only shows titles present in an imported library, hiding itself below five matched cards; its rail label names the seed ("Because you watched X") when exactly one seed contributed. `trendingCards` shows TMDB's weekly trending and falls back to a prefilled global search for unmatched titles. Contracts: `docs/architecture/tmdb-metadata-enrichment.md` ("Dashboard Integration"). 6. `sourceCards` — maps `recentPlaylists()` to rail cards. `recentPlaylists()` ranks M3U, Xtream, and Stalker sources by their latest recent activity from `globalRecentItems()`, then falls back to playlist `updateDate` / `importDate` for sources that have never been used. 3. `DashboardDataService` is passive on construction. The dashboard feature owns the initial reloads for recent items, favorites, and Xtream recently added rows on page entry. 4. No dashboard-local `Layout` state, no localStorage keys, no migrations. Per-rail visibility is the one persisted preference, and it lives in the global settings store (`Settings.dashboardRails`), not in a dashboard-owned layout blob. 5. Navigation state + deep-link targets come from the existing `getRecentItemLink()` / `getGlobalFavoriteLink()` / `getPlaylistLink()` helpers on `DashboardDataService` and reuse the workspace navigation helpers in `@iptvnator/portal/shared/util`. 6. Xtream VOD and series detail pages opportunistically backfill `content.backdrop_url` when metadata exposes a backdrop, but that write must not refresh recently viewed ordering by itself. 7. The dashboard feature triggers a fresh reload of DB-backed recent/favorite rows on dashboard entry so newly backfilled backdrop data is visible as soon as the user returns from a detail page. 8. Playback-position reloads are keyed by the VOD/series recent set and should call `reloadPlaybackPositions()` through `untracked()` so live-only recent changes do not trigger unnecessary IPC round-trips. 9. Electron M3U dashboard favorites should use `PlaylistsService.getM3uFavoriteChannels()` first. That method checks the SQLite playlist migration flag and then calls `dbGetAppPlaylistFavoriteChannels(playlistId)`, letting the DB worker return only matched favorite channels instead of sending the full playlist payload back to the renderer. If the bridge method is missing or migration is incomplete, the dashboard falls back to the full playlist read. 10. Electron playlist summary loads should use `dbGetAppPlaylistMetas()` through `PlaylistsService.getAllPlaylists()`. This keeps dashboard/source/sidebar startup on a metadata-only SQLite path and avoids parsing full M3U `payload` blobs for surfaces that only need playlist title, type, counts, favorites, recent activity, and source connection fields. Workflows that need channel payloads still call `getPlaylistById()`. ## Empty State The welcome state is rendered via the existing `EmptyStateComponent` (`type="welcome-dashboard"`) from `libs/playlist/shared/ui`: 1. Illustration + headline + description from the existing M3U welcome strings (`HOME.PLAYLISTS.WELCOME_*`). 2. Primary button emits `addPlaylistClicked`. The dashboard page wires this to `WORKSPACE_SHELL_ACTIONS.openAddPlaylistDialog()`. 3. Feature chips (M3U / Xtream / Stalker) are provided by the component. ## UX Rules 1. Rails represent content the user is likely to resume, not provider internals. Never surface raw API objects. 2. Each rail must auto-hide when its data source is empty. 3. Image assets must degrade to a typed icon fallback — never show broken images or empty tiles. 4. The page must never show "No widgets" style text. If there is no content and no playlists, render the welcome state; otherwise render whatever rails have data. 5. Navigation from a rail card must deep-link into the appropriate workspace route without switching the active playlist in the header switcher. 6. Xtream and Stalker series hero/Continue Watching clicks with a saved episode position must resume that exact episode while preserving the collection-owned detail and Back behavior. Do not apply autoplay to ordinary collection-grid clicks. 7. `Recently Used Sources` reflects recent source usage across all provider types, not just recent imports. 8. The live rail title key must match the rendered source: favorites use `WORKSPACE.DASHBOARD.LIVE_FAVORITES`; the recently-watched-live rail uses `WORKSPACE.DASHBOARD.RECENTLY_WATCHED_LIVE_TV` (`liveRailTitleKeyForSource` in `rails/dashboard-rail.utils.ts`). ## Adding Or Changing Rails Current workflow: 1. Add a new `computed()` signal for the card list in `WorkspaceDashboardRailsComponent`, mapping your source data to `DashboardRailCard`. 2. Drop a `` in the template, gated by `@if (cards.length > 0)`. 3. If the data source is new, extend `DashboardDataService` rather than reaching into DB services directly from the component. 4. Provide a `seeAllLink` only if there is a dedicated "manage all" route for that content type. ## Deferred Work Intentionally out of scope: 1. Customizable layout (drag/drop, resize, freeform reordering). The rail order stays curated and opinionated. (Per-rail show/hide toggles have since shipped via `Settings.dashboardRails` — see Summary.) 2. Freeform widget grid with collision management. 3. External data rails such as RSS, sports, or news adapters. 4. Per-user A/B variants of rail ordering. ## Source subscription expiry Source cards show a passive subscription-expiry chip: amber within seven days, error-toned once expired. Account details stay behind the Account info menu. `DashboardSourceExpiryService` in `libs/workspace/dashboard/data-access` reads Xtream expiry from cached `PortalStatusService.checkPortalStatusDetails()` (`exp_date`). Stalker uses the persisted `stalkerAccountInfo` snapshot from the playlist payload, not the metadata row; each source therefore needs one memoized full-playlist read. The chip is not a separate account-refresh request.
