Stalker Store API Baseline

This is the compatibility baseline for refactoring libs/portal/stalker/data-access/src/lib/stalker.store.ts.

Goal: keep this public surface stable while splitting to feature stores.

Source of Truth

• Store implementation: libs/portal/stalker/data-access/src/lib/stalker.store.ts
• Baseline created on current branch state before feature-store extraction.

Public State Signals

Direct signal properties currently exposed by signalStore:

• selectedContentType: 'vod' | 'itv' | 'series'
• selectedCategoryId: string | null | undefined
• selectedVodId: string | undefined
• selectedSerialId: string | undefined
• selectedItvId: string | undefined
• limit: number
• page: number
• searchPhrase: string
• currentPlaylist: PlaylistMeta | undefined
• totalCount: number
• selectedItem: StalkerVodSource | null | undefined
• vodCategories: StalkerCategoryItem[]
• seriesCategories: StalkerCategoryItem[]
• itvCategories: StalkerCategoryItem[]
• hasMoreChannels: boolean
• itvChannels: StalkerItvChannel[]
• vodSeriesSeasons: StalkerVodSeriesSeason[]
• vodSeriesEpisodes: StalkerVodSeriesEpisode[]
• selectedVodSeriesSeasonId: string | undefined

Public Computed Selectors

• getTotalPages: number
• getPaginatedContent: StalkerContentItem[]
• isPaginatedContentLoading: boolean
• isPaginatedContentFailed: unknown
• getSerialSeasonsResource: StalkerSeason[]
• isSerialSeasonsLoading: boolean
• getVodSeriesSeasonsResource: StalkerVodSeriesSeason[]
• isVodSeriesSeasonsLoading: boolean
• getCategoryResource: StalkerCategoryItem[]
• isCategoryResourceLoading: boolean
• isCategoryResourceFailed: unknown
• getSelectedCategoryName: string

Exposed Resources/Props

These are currently reachable on the store object and used internally by computed selectors:

• getCategoryResource (computed selector with stable array output)
• categoryResource (internal resource)
• getContentResource (resource)
• serialSeasonsResource (resource)
• vodSeriesSeasonsResource (resource)
• makeStalkerRequest(...)

During refactor:

• Keep compatibility for external callers that may read these directly.
• If moved/renamed internally, provide facade aliases.

Public Methods (Compatibility Contract)

• setSelectedContentType(type: 'vod' | 'itv' | 'series'): void
• setSelectedCategory(id: string | number | null): void
• setSelectedSerialId(id: string): void
• setSelectedVodId(id: string): void
• setSelectedItvId(id: string): void
• setLimit(limit: number): void
• setPage(page: number): void
• setCurrentPlaylist(playlist: PlaylistMeta | undefined): Promise<void>
• setSelectedItem(selectedItem: StalkerVodSource | null | undefined): void
• clearSelectedItem(): void
• setCategories(type: 'vod' | 'series' | 'itv', categories: StalkerCategoryItem[]): void
• resetCategories(): void
• setItvChannels(channels: StalkerItvChannel[]): void
• setSearchPhrase(phrase: string): void
• fetchVodSeriesEpisodes(videoId: string, seasonId: string): Promise<StalkerVodSeriesEpisode[]>
• getSelectedCategory(): { id: string | number; name: string; type: 'vod' | 'itv' | 'series' } Backed by withComputed for compatibility, not by withMethods.
• fetchLinkToPlay(portalUrl: string, macAddress: string, cmd: string, series?: number): Promise<string>
• getExpireDate(): Promise<string>
• addToFavorites(item: any, onDone?: () => void): void
• removeFromFavorites(favoriteId: string, onDone?: () => void): void
• fetchMovieFileId(movieId: string): Promise<string | null>
• createLinkToPlayVod(cmd?: string, title?: string, thumbnail?: string, episodeNum?: number, episodeId?: number, startTime?: number): Promise<void>
• addToRecentlyViewed(item: any): void
• removeFromRecentlyViewed(itemId: number, onComplete?: () => void): void
• fetchChannelEpg(channelId: number | string, size?: number): Promise<EpgItem[]>

Current Consumers (Observed)

Top observed store API usage in app code:

• currentPlaylist (16 references)
• setSelectedContentType (9)
• selectedItem (9)
• setSelectedItem (7)
• setSelectedCategory (6)
• createLinkToPlayVod (6)
• removeFromFavorites (5)
• setPage (4)
• addToFavorites (4)
• fetchChannelEpg (3)
• plus lower-frequency calls for paging/resources/series/recent.

Consumer directories sampled:

• libs/portal/stalker/**
• libs/portal/xtream/feature/**
• libs/portal/catalog/feature/**
• libs/ui/components/**

Invariants to Preserve During Refactor

• Selection IDs (selectedVodId, selectedSerialId, selectedItvId) are synchronized in setSelectedItem.
• setSelectedCategory(...) resets page to 0.
• getPaginatedContent() and getCategoryResource() always return arrays, even when the underlying request fails.
• Request failures must surface through isPaginatedContentFailed() and isCategoryResourceFailed() rather than resource reads that throw.
• createLinkToPlayVod(...) continues to:
  • support episode playback metadata
  • append recently viewed
  • preserve external player payload shape
• Full-portal auth path continues through StalkerSessionService.
• Non-auth/simple path continues through DataService.sendIpcEvent(STALKER_REQUEST, ...).
• Resource-driven loading signals preserve existing names.
