Phases 4 + 5 of the metadata overhaul (plan §4, §5) plus §3 handler
wiring.
Filters (§4.1): author_filter/publisher_filter now match per-element
against the authors[]/publishers[] arrays — a co-authored book matches
any one of its authors — with comma-joined params acting as
OR-within-facet multi-select (string_to_array + cross unnest). Legacy
single-value params unchanged on the wire; series/genre/language
filters stay on their varchar columns; narrator filter already
per-element.
Collections API (§3.3-3.5): collection detail carries viewer +
hide_finished into the listing query and exposes up_next (visible-
library-enforced reading-queue head); PUT
/api/collections/:id/items/order (owner-only, full-order rewrite);
UpdateCollectionRequest gains hide_finished/show_up_next ([]
string last-value-wins for the hidden-false-sibling checkbox pattern)
merged server-side OVER stored view_settings so imported_from_series
provenance survives edits; EditCollectionModal renders the toggles
from view_settings.
Dashboard (§5.5): sections JSON carries is_playlist/complete
(dashboard.ts is the AGENTS-documented JSON-render exception; first
paint stays templ). Fully-read playlists render '✓ Playlist complete'
instead of an empty rail; imported playlists get a 📖 Playlist badge.
Frontend: book detail shows subtitle + full authors + Explicit badge;
edit modal gains subtitle, comma-separated authors/publishers (client-
split to arrays exactly like narrators), step=any series number,
explicit checkbox; collection book cards get playlist move ↑/↓ buttons
persisting the full order via the reorder endpoint (templ partial
re-render on failure — DOM order is client-local, API order is truth).
AGENTS.md gotcha #3 amended per plan §3.7: user collections are
dashboard sections by default; the show_on_dashboard premise is
retired.
Verified: full affected integration sweep green (pins widened for
up_next/is_playlist/complete — changelog entries in
docs/contract_pins.md); unit suite green; go build + templ + vite
green.
Phase 2b + 3 of the metadata overhaul (plan §2.4, §3.1-3.7).
Auto-playlist collections (§2.4): the scanner turns obviously-playlist
sidecar series (explicit '(Reading Order)'/chronological/publication/
in-order/timeline markers only — precision over recall) into curated
static collections: upsert by view_settings.imported_from_series then
name (rename-safe), position set ONLY on insert (clean integers; 1.5/1a
stay unpositioned rather than guessing), membership add-if-missing,
never removed or re-ordered by rescans, provenance in description +
view_settings, show_on_dashboard true (dashboard-eligible by design),
'scanner.auto_playlist_collections' setting (default on, Settings
Registry + schema seed).
Ordering (§3.1-3.2): collection listings order position ASC NULLS LAST
then added_at ASC (was added_at DESC — walked playlists backwards);
PUT /api/collections/:id/items/order applies full-order rewrites
(owner-only, service-gated).
hide_finished + Up Next (§3.3-3.4): GetCollectionItemsForDashboard
gains viewer_user_id + hide_finished (LEFT JOIN reading_progress,
COALESCE percentage < 0.999) and viewer_percentage rides the row for
card graying; GetCollectionUpNext serves the collection's reading-queue
head with the family-lens visible-library array enforced.
Dashboard (§3.5): user collections are dashboard-ELIGIBLE BY DEFAULT —
the show_on_dashboard gate (never writable for user rows since the
column shipped) is gone from GetUserCollectionsForDashboard; hiding
stays dashboard-prefs (hidden_collections) territory; hide_finished
filtered-everything now emits a Complete section instead of silently
vanishing; sections JSON carries is_playlist/complete.
Series page ordering hardening (§3.6): GetSeriesBooks tiebreaks by
title ASC — NULL/tied numbers previously returned heap (scan) order,
which is what the user saw.
Frontend custom-section-builder note: the builder has sent
show_on_dashboard: true since its creation; the API never bound it.
User-row visibility is now intentionally prefs-governed, so the field
stays unbound by design (documented in code).
Pins widened (docs/contract_pins.md): collection detail + up_next;
dashboard sections + is_playlist/complete; new reorder endpoint
recorded.
Verified: TestPlaylistCollectionsEndToEnd (new, full e2e: sidecar
series split, collection auto-creation with position 7, rescan
idempotency, owner-only reorder, finished-filter + completion marker +
Up Next drain) plus the full affected integration sweep green.
collections.userVisibleLibraryIDs keeps its identity adapter and
delegates; the router's visibleLibraryIDsFor likewise (its identity
source is the session user_id string, the site-specific part it keeps).
The SSR site made the unification slog-proof: resolveLibrary — the SSR
one-of-a-kind (active selection + switcher rows + offline detection) —
stays untouched per the semantic diff.
SELECT mi.*, ci.excluded forced every caller to filter tombstone
exclusions in Go over a 69-field row, then a 45-field hand converter
(getCollectionItemsRowToMediaItems) copied it field-by-field into
MediaItems for BuildSections. The query now filters
(ci.excluded IS NOT TRUE) itself and returns sqlc.embed(mi) — callers
consume .MediaItems directly, the Go filter loops die in both
collection-detail ladders (JSON + SSR), and the converter is deleted.
Pins, H1/H3 tests, unit suites green.
checkRulesAgainstBook/evaluateRule and the service's EvaluateRules
existed in two parallel universes: one over database.MediaItems (what
every query actually returns) and one over ListMediaItemsRow (what two
hand-written 45-field mediaItemsToListMediaItemsRow converters
produced — verbatim twins in the handler and the dashboard service,
with a URL-resolution side effect baked into a "converter"). The rule
fields (genre/series/author/language/publisher/copyright_year/tags)
all exist on MediaItems, so the evaluators now take the real row and
the converters, their three call-site loops, and the dead
ApplyAutoAssignRules entry point (zero callers) are gone.
The rules surface is wire-covered by the collections rules scenarios;
handlers+services suites and the full pin/H1/H3 battery green.
handlers textToString, router textToString, router getText, and utils
normText were four copies of the same NULL-to-empty unwrap (99 call
sites). One exported utils.PgTextString replaces them all; the private
normText (comparison normalizer) stays but is now the odd one out.
Harness fix found on the way: setupTestServer built a full wiring
literal for route registration and then RETURNED a second, sparser
literal that never copied AnnotationService — setup.AnnotationService
was always nil on the struct every test receives. Nobody noticed until
cross_library_move_test became the first caller (it previously used
the now-retired plain CreateMediaHighlight query); it now exercises
the real SaveHighlight path through the wired service.
The last behavior gap in the H2 batch: has_conflict was part of the
frozen card shape but stamped false-forever on these three JSON
surfaces (only dashboard sections, search, and the SSR pages had it),
so every conflict-driven card action — the resolve-conflict CTA in
BookCard — never fired there. MarkActiveConflicts now runs after the
builder on GET /api/collections/:id, series books, and smart-collection
preview (all user-scoped; the endpoint already authenticates).
Key set is unchanged — has_conflict was always emitted, this only
makes its value truthful. All 15 contract pins + H1 tests green; the
pin's bookInfoKeys freeze unaffected.
POST preview-feed had the ladder's 14th hand-rolled literal. Now
BookCardsFromMediaItems + one LibraryTypeMap per request; the response
carries format_group/badge values for the first time (all seven keys
were already emitted as zero-value JSON, so this is a value change on
a pin-frozen shape, not a key change).
GET /api/collections/:id books — all four branches now build cards via
the cards.go adapters. LibraryTypeMap hoisted to once per handler (it
was 1 query per item in the smart and no-library branches). The system
branch — which before stamped cards BARE (no format_group, no badge —
the ladder's only JSON gap) — now emits the same card shape as its
siblings by feeding section.Items through BookCardsFromMediaItems,
matching what BuildSections produces for the identical data. The
collection-error seed dies via the adapters' non-nil empty slices;
the no-matching-section nil result is preserved as-is (that branch
never seeded — today's 'items': null stays today's 'items': null).
Pins: CollectionsJSON, DashboardSections, MediaListBothBranches green.
BookInfo, LibraryTypeMap, and MediaBadgeKind move verbatim out of
collections.go into handlers/cards.go (the card package surface, same
package: no import-graph or templ changes), joined by the H2 builder:
- buildBookCard (unexported): the ONLY place BookInfo is constructed,
fed by cardSource; cover URL via ResolveMediaURL, badge via
MediaBadgeKind — both inside the builder, not per call site.
- Four exported adapters normalize the four real feed shapes:
database.MediaItems (sections/smart/series/tags/preview),
GetCollectionItemsForDashboardRow (collection dashboard branch),
GetCollectionItemsRow (collection-items joins — MediaItemID field),
SearchMediaItemsUnifiedRow (badge rides its LibraryTypeName column,
so no LibraryTypeMap query at all).
- Adapters return non-nil empty slices, which retires the per-site
[]BookInfo{} empty-seed assignments when call sites migrate.
No call site changes in this commit — the 20 literals and 5 seeds are
migrated one surface per commit next, each with the H0 pin suite.
Verified: build, vet (only the two pre-existing flagged saveCoverImage
warnings), and 14/14 contract pins — the key freeze is byte-identical.
Reader fullscreen: the topbar gains a fullscreen toggle (icon state + f
shortcut + help row; f is guarded so Ctrl/Cmd+F stays find-in-page).
Enter requests the Fullscreen API with fallbacks (desktop/Android get a
true full display; iOS Safari has no page-fullscreen API and falls back
to the soft visual mode only). Margins: the foliate paginator's closed
shadow root only yields through its observed 'margin' attribute, so
fullscreen fits a comfortable ratio (6% of the short side, floored at
48px) and floors it by the measured env insets — Android reports true
cutout insets in fullscreen, so portrait phones keep text clear of the
camera band; iOS letterboxes are already env-padded chrome. Fixed-layout
renderers skip it (fxl/webtoon pack pages edge-to-edge by design).
Exits the user makes outside the toggle (Esc, browser UI) sync via
fullscreenchange(+webkit) and restore the ordinary 48px margin; a
position-keeping re-render follows the ResizeObserver re-entry path.
Verified on-device: enter -> true fullscreen + icon swap + camera band
clear, exit -> chrome back, margins restored, position kept.
Volume: revert the stacked panel — the popup returns to the liked shape
(mute button left, horizontal dragger right, dialogue above the strip);
one-line flex restore of the pre-89665fb layout.
Manga badges: MediaBadgeKind makes the library type authoritative for
the comic/manga split — manga volumes ship as fixed_layout scans as
often as comic_archive (and manga_type is unreliable across sources:
unknown/NULL on real rows), so the old comic_archive+manga mapping left
the scan volumes unbadged. Anything in a manga library reads manga;
anything in a comics library reads comic. Verified: /dashboard lands 24
title="Manga" cover badges for the Manga library and the sections API
reports badge=manga for a fixed_layout item.
Ghost sidebar: the >=1024px media block applied body
padding-left:var(--sidebar-w) unconditionally, so pages that never
render the sidebar (logged-out pages, the audio player, the reader
itself) carried a phantom 16rem left margin that pushed content off
center on desktop widths. The body:has(.app-sidebar) rule below was
already the correct conditional source — it is now the only one.
Verified in the built stylesheet: exactly one such rule remains.
Infra: main.js ?v=3 stamp bump (reader.ts changed; hashed chunks churn
their URLs themselves).
Annotations banner: audio/text bookmarks join notes and highlights —
third row kind (bookmark glyph indicator, H:MM:SS / Page N / Chapter N
friendly labels), edit-note/delete actions branch by kind, and the
banner's export now covers all annotations. The archived ledger
(ListDeletedAnnotationsForBook) already tombstoned bookmarks equally
and Restore/Purge take annotation_type=bookmark — verified live:
delete → restore brings the row back with its note intact.
Volume: the dragger sits BELOW the mute icon in the panel (stacked
flyout shape) with the horizontal slider from the last round.
Badges: the real fix for comics/manga — format_group only knows
'comic_archive' (manga_type is unreliable across sources), so the
comic/manga split is resolved from the LIBRARY type server-side.
handlers.MediaBadgeKind + BookInfo.Badge at every construction site
(dashboard SSR + sections API, collections, series, and the bookshelf
search grid — which was also missing FormatGroup entirely, so no card
ever badged there). Both renderers (templ + dashboard.ts) switch on
the resolved badge. Verified: All-Books grid renders 2 Comic + 3
Manga badges, dashboard the audiobook one.
Infra: header.templ main.js src gains ?v=<stamp> — browsers keyed an
intermediate bundle by URL and served it across rebuilds (the stale
'Add note' the user saw); bump the stamp when JS stale-shadows.
A2a (metadata round): narrators TEXT[] + narrators_search (tags
pattern: accumulator + GIN pairs) + abridged bool on media_items;
scanner fills from the Libation/ABS sidecar (narrators verbatim,
abridged flag) with audio-payload promotion; editorial fields ride
the real columns while audio_metadata stays scan-derived (duration/
codec/chapters). Detail/edit/save paths carry the fields; the web
edit dialog grows an Audio section (Narrator(s) comma-input, Abridged
toggle, scanned duration read-only); search weights + narrator filter
(word_similarity over narrators_search) + narrator autocomplete added.
A2c (per-media-type wording): copy helpers keyed on format_group —
Listen Now, Mark Complete/Not Complete, Listening Progress, Your
Listening Stats, Time Listening, Time listened (pages tile swapped for
audio), Position H:MM:SS / total H:MM:SS on detail + progress pages
(duration parsed from audio_metadata). Dashboard: system collections
swap to Continue Listening / Recently Listened at DISPLAY time when
the audiobooks library is selected (stored names unchanged; restores
keep working); week card = Listening Time / Sessions / Books Touched;
cover-corner badges identify audiobook (headphones) / comic / manga
cards on mixed grids — books stay unbadged; hover action icon follows
the media type.
A2b (player): the scrubber binds value to the playhead with an explicit
scrub guard (the handle previously froze at its initial max); header
row = reader-style back arrow + Chapter n/total launcher; chapters
open in a floating top-down drawer (current chapter highlighted, page
never shifts); Skip/Speed rows share one label-left layout; honest
wall-clock session accounting (playing-only deltas, paused flush).
A2d (bookmarks): note-bearing time bookmarks ride the existing
media_bookmarks substrate (notes column + sync-aware service already
there) — audio locator convention audio:<seconds>, chapter_number
filled, auto-title '<chapter> — H:MM:SS', capture popover with optional
note, drawer with jump/edit-note/delete. Zero server changes needed.
Verified live on the Libation sample: narrators backfilled by rescan;
PUT edit persisted + overrides detected (narrators, abridged); force
rescan preserved the user edit; reset-to-scanned-of-defaults restored
truth; narrator filter/autocomplete scoped by library; dashboard
listsening wording + badges render; bookmark save with note deduped to
one row.
Type is DERIVED, not stored: a saved ruleset makes a collection SMART,
no rules = STATIC (stored collection_items links, unchanged behavior).
No schema change — collections.auto_assign_rules JSONB already carried
the config; user's decision 2026-10-14 (handoff: live-at-render, not
refresh-on-scan; create-time Static/Smart toggle; v1 NO hybrid).
- Rule gains an enabled flag (absent = enabled, legacy rules unaffected).
- Rule CRUD: POST/PUT(DELETE) /api/collections/:id/rules[/:ruleId] — the
survivor dead effort of the rules-builder UI finally has real
endpoints (rules were never editable after creation; nothing ever
re-evaluated them). First rule converts a user collection to smart;
removing the last reverts it to static. UpdateCollectionRulesJSON
edits ONLY the rules doc so rule CRUD cannot clobber metadata.
- Live evaluation: candidates from GetVisibleLiveMediaForRules —
visible-library set (family lens enforced at source) + archived IS
NULL AND missing_scan_count = 0 — any enabled rule matches, title
order. Zero refresh hooks by design: always current by construction.
- Membership mutations (add/remove/bulk-add) are 400 on smart — v1 no
hybrid; collection_items.excluded stays the reserved future hook.
- Rules builder page (/collections/:id/rules) first time ever routable;
templ whole-attribute interpolation ("{ expr }" inside a quoted attr
value is literal text, as theme-{ user.Theme } silently proved).
- UI: create modal Static/⚡Smart cards (smart create redirects into the
rules builder), ⚡ badge + real per-card counts on the grid (smart =
live matches, static = stored-link count), smart detail renders
matched books with no hand-pick actions + an Edit Rules button.
- API: GET /:id gains is_smart + live books; GET /: keeps the Android
app's default exclusion, include_auto=true surfaces smart rows with
live counts; TestRules previews against the SAME candidates the live
render uses (visible + live, was raw first-1000).
- FIXED pre-existing regression from 7ce7321: static collection detail
with NO library_id returned zero books — QueryType != '' caught user
rows ('filter' default) and routed them to dashboard sections that
never contain them; now only real system query types go there
(handlers + SSR). App-visible symptom: /api/collections/:id without
library_id came back books:[] for every static collection.
Tests: collections_smart_test.go (conversion, disabled rules, mutation
guards, revert-to-static, validation, system-collection prohibition,
include_auto semantics). Full offline integration suite PASS.
The old model hard-deleted system collections and re-created them at
the tail, resurrecting stale dedups and breaking ordering. Redesign
(user-directed B-final):
- schema.sql: collections.deleted_at TIMESTAMPTZ (idempotent ALTER —
the whole schema is re-applied on every boot via executeSchema).
- queries.sql: every collection list/read query filters
deleted_at IS NULL; new GetSystemCollectionByQueryType :one
(unfiltered, sees tombstones), TombstoneSystemCollection :exec,
ClearCollectionItems :exec, RestoreSystemCollectionRow :one
(in-place metadata reset + un-tombstone; collections have no
updated_at column — ResetUpdatedAt was a 500 caught by tests).
sqlc regenerated.
- collection_service.DeleteCollection: system collections are
tombstoned (preserving position/ownership); user collections keep
the hard delete. No ErrNoRows to the client (delete is idempotent).
- dashboard_service.RestoreSystemCollection: resolve by query_type;
found → in-place restore (ClearCollectionItems + metadata reset,
un-tombstoned); missing → provision fresh. "Want to Read"/etc.
stay at their home positions forever.
- handlers/collections.CreateCollection: name-taken is 409, not 500.
- handlers/auth.CreateDefaultCollectionsForUser: idempotent by
(user_id, query_type) — update-in-place when a row for that query
type exists (heals renames/tombstones), insert when missing; this
also fixes the duplicate-system-collections regression at source.
The play button on book cards now opens the reader directly, instead of
always going to the detail page. Cards with an active progress sync
conflict route the play button to the detail page (which hosts the
conflict dialogue and resolves before writing progress), so the user is
never silently dropped into the reader with an unresolved conflict.
Backend:
- Add HasConflict to BookInfo and stamp it via ListSyncConflictsByUser
(MarkActiveConflicts / MarkActiveConflictsSections) on the dashboard,
bookshelf, series, tag, and search result card builders.
- Each page issues a single conflict query regardless of card count.
BookCard:
- Restructure into a detail link (cover + meta) with the play action as a
sibling overlay using a pointer-events split: the container passes
clicks through to detail while only the circular button routes to the
reader. No nested anchors.
- On touch devices (hover: none) the play button stays visible.
Fix: carousel nav buttons had opacity-0 without pointer-events-none, so
they swallowed hover/clicks over book cards on the dashboard. They are
now click-through until the carousel is hovered.
- dashboard.go: library_id query param is now optional. Empty/missing
library_id is passed as pgtype.UUID{Valid: false} to the service
layer, enabling All Libraries mode.
- series.go: library_id is optional for series listing. GetSeriesBooks
no longer receives a libraryID — it always returns all books in a
series regardless of library.
- collections.go: Restructure GetCollection to handle system
collections (query_type != "") with an optional libraryID. When
libraryID is empty (All Libraries), GetDashboardSections receives
pgtype.UUID{Valid: false} so no library filter is applied.
Add optional library_id query parameter support to GetCollections and
GetCollection API handlers for library-scoped book filtering.
GetCollections (GET /api/collections?library_id=X):
- When library_id is provided, include per-library book_count in the
response by querying GetCollectionItemsForDashboard for each collection
- When omitted, returns all collections as before (backward compatible)
- Added BookCount field to CollectionResponse struct
GetCollection (GET /api/collections/:id?library_id=X):
- System collections (non-empty QueryType): uses DashboardService to
fetch library-scoped sections, matching the existing SSR handler logic
- User collections: uses GetCollectionItemsForDashboard for
library-filtered results, excluding soft-deleted items
- When library_id is omitted, returns all books as before
Remove redundant type conversions that Go 1.26 makes unnecessary or that
were already no-ops:
- uuid.UUID(x.Bytes) → x.Bytes (uuid.UUID is [16]byte, same as pgtype UUID Bytes)
- pgtype.UUID{Bytes: [16]byte(u), Valid: true} → pgtype.UUID{Bytes: u, Valid: true}
- (*time.Time)(&x.Time) → &x.Time
- json.RawMessage(x) → x where x is already []byte
- []byte(stringVal) → stringVal where []byte is expected
- int()/int64()/byte() casts on values already of the target type
- Decompressor(fn) → fn (type is identical)
Handle previously ignored error returns:
- collections.go: check json.Unmarshal error in GetCollection
- conversion_service.go: check fileSize.Scan() error
- app_test.go: check app.Shutdown() error in benchmark
Replace direct error equality checks (err == pgx.ErrNoRows, err != http.ErrServerClosed)
with the idiomatic errors.Is() function throughout handlers, services, middleware, and app
startup. This correctly handles wrapped error chains.
Also replace a raw type assertion (*HTTPError) with errors.AsType[*HTTPError]() in the
error handler middleware for consistency.
Additionally, rename shadowed variables for clarity:
- sidecar.go: config -> sidecarConfig, systemConfig (shadowed package-level vars)
- media_scanner.go: uuid -> uuidString (shadowed the uuid package import)
- Add library_type_name to GetMediaItem handler response in media.go
- Remove empty LibraryName and LibraryTypeName fields from:
- ListMediaItemsRow in collections.go handler
- ListMediaItemsRow in dashboard_service.go
- These fields are now populated at the database level via trigger
The library_type_name is now automatically populated in the database
when a media item is created, so we remove the manual empty string
assignments and expose the actual value in the API response.
Add real-time synchronization for collection book removal:
- Extract user ID from context for targeted broadcasts
- Broadcast 'collection_updated' message to user's other devices
- Includes collection_id, action, and book_id in message payload
This ensures that when a user removes a book from a collection,
all their connected devices (browser tabs, mobile apps, etc.)
receive real-time updates via WebSocket.
Consistent with existing AddBooks and BulkRemoveBooks operations
which already use BroadcastToUser for synchronization.
This commit adds comprehensive functionality for filtering collections by library,
improves WebSocket real-time updates with user activity detection, and adds
extensive test coverage.
## Core Features

- Collections can now be filtered by specific library
- Toggle UI component for enabling/disabling library filter
- Default state is "checked" when library_id is present
- Consistent behavior across partial and fuzzy search modes
### WebSocket Auto-Reload Mitigation

## Breaking Changes
None - all changes are additive and backward compatible.
Add form:"" tags to CreateCollectionRequest and UpdateCollectionRequest
structs to enable proper form data binding with Echo's c.Bind().
This change aligns with the pattern used in auth handlers where both
form:"" and json:"" tags are present, allowing the same request structs
to work with both JSON payloads (API) and form data (HTMX).
Changes:
- Add form:"name", form:"description", form:"color", form:"icon",
form:"auto_assign_rules", and form:"view_settings" tags to both
CreateCollectionRequest and UpdateCollectionRequest
Additionally, add HTMX redirect support to CreateCollection and
UpdateCollection handlers:
- Add HX-Redirect header for HTMX requests after successful create/update
- Add HTML redirect response to DeleteCollection for HTMX requests
(follows pattern from auth.go: inline script with window.location.href)
This ensures HTMX form submissions properly redirect to /collections
after successful operations, while maintaining API compatibility for
JSON requests.
Add comprehensive collection detail page that works for both system collections
(continue-reading, recently-added, not-started) and user collections.
Backend changes:
- Add new /collections/:id route in internal/router/frontend.go
- Fetches collection using GetCollection with UUID parameter
- Determines collection type from QueryType field
- Resolves library_id for system collections
- Converts database.MediaItems to handlers.BookInfo for display
- Renders CollectionDetail template with collection and books data
- Update SectionData struct in internal/handlers/collections.go
- Add CollectionID string field for view all links
- Update BuildSections() in internal/handlers/dashboard.go
- Pass CollectionID to SectionData for proper link generation
- Simplify getViewAllURL() in internal/handlers/dashboard.go
- Return /collections/{collectionID} instead of /section/{type}
- Works uniformly for both system and user collections
Frontend changes:
- Fix CollectionDetail template in templates/collections.templ
- Fix broken div nesting causing compilation error
- Add null check for CoverImagePath to prevent broken images
- Update aspect ratio to modern aspect-[3/4] syntax
- Use responsive widths (w-16 sm:w-20) for mobile/desktop
- Improve card layout with horizontal flex structure
- Add placeholder image fallback for books without covers
- Remove erroneous renderBooks() function call
This change aligns with the backend update where system collections are
now pre-made user collections in the database with query_type fields.
All collections can now use the same CollectionDetail template for a
consistent viewing experience.
- Implement event queue with 3-second debouncing for file system events
- Add configurable polling fallback (default 3 min) via SCAN_POLL_INTERVAL_MINUTES
- Add SyncFilesystemWithDatabase to detect orphaned DB entries and new files
- Integrate utils.ResolveMediaURL for consistent media file path resolution
- Add COOKIE_SECURE env var with SameSite=LaxMode for session cookies
- Update media handler to properly decode URL paths for file serving
- Refactor scanner initialization to accept poll interval configuration
- Add libraryService dependency to CollectionHandler and OPDSHandler for centralized path resolution
- Create internal/utils/mediaurl.go with ResolveMediaURL() function as single source of truth
- Update GetMediaItem and ListMediaItems handlers to return resolved URLs in API responses
- Update collection handlers (GetCollection, TestRules, PreviewCollection) to use resolved cover URLs
- Update progress handler (GetAllProgress) to use resolved cover URLs
- Add library_id to GetCollectionItems SQL query to enable URL resolution
- Refactor media scanner to store relative paths instead of absolute filesystem paths
- Add ResolveMediaPath() to LibraryService for resolving relative paths to absolute paths
- Add ServeFile endpoint at /uploads/library-:id/* for authenticated file serving
- Add MimeTypes map to library_service.go for consistent MIME type handling
- Update DownloadBook handler to use resolved filesystem paths
- Add getRelativePath() helper to MediaScanner for converting absolute to relative paths
- Use strings.EqualFold for case-insensitive path comparisons in zip extraction
This change enables the application to work with relative paths stored in the
database, making it portable across different server environments while
maintaining backward compatibility with existing absolute paths.
Implement DeleteUser, ResetUserPassword, and UpdateUserAdmin handlers.
Update collections handler to check soft-deleted users. Update dashboard
service to exclude deleted users from statistics.
The PreviewCollection endpoint was missing authentication verification,
allowing unauthenticated access to the preview functionality. Added
check for user in context, returning 401 Unauthorized if missing.
Add preview endpoint for custom section builder and rule evaluation:
Handler Implementation (internal/handlers/collections.go):
- PreviewCollection method: Evaluates filter rules and returns matching items without saving
* Accepts library_id, rules array, manual_book_ids array, and limit
* Evaluates rules against all library items using collectionService.EvaluateRules
* Adds manually selected books to results
* Deduplicates manual books (avoids adding same book twice)
* Applies limit (default: 20, max: 100)
* Returns array of BookInfo with matching items
- Helper function: mediaItemsToListMediaItemsRow
* Converts database.MediaItems to database.ListMediaItemsRow
* Required for EvaluateRules which expects ListMediaItemsRow type
Route Registration (internal/router/collections.go):
- POST /api/collections/preview
- Protected by JWT middleware
- Part of collections API group
Why This Endpoint is Necessary:
- Allows users to see what books match their filter rules BEFORE saving
- Avoids creating incorrect collections
- Enables testing different rule combinations quickly
- Reuses existing service logic (collectionService.EvaluateRules)
- Client-side preview would require downloading entire library (10,000+ books)
- Would duplicate 500+ lines of rule evaluation logic in TypeScript
- Would create maintenance nightmare keeping Go and TypeScript in sync
Bruno Test (bruno/collections/preview-collection.bru):
- Tests POST /api/collections/preview endpoint
- Validates status 200 response
- Validates items array in response
- Example request with genre filter rule
This endpoint is required for both the web UI Custom Section Builder and future mobile apps.
Add dashboard API endpoints with handler layer:
Step 1: Add SectionData to collections.go
- SectionData struct represents dashboard section (carousel of books)
- Used by: Dashboard handler, Templates (SSR), API JSON responses
- Shared type from collections.go (no duplicate definitions)
- Fields: ID, IsSystem, Title, Description, Icon, Items, ViewAllURL, Priority
Step 2: Create dashboard.go handler
- DashboardHandler struct with injected database and dashboard service
- GetSections: Returns dashboard sections as JSON (mobile apps, web UI TypeScript, plugins)
* Validates library_id parameter
* Fetches user dashboard preferences
* Configurable limit (default 20, max 100)
* Calls service layer for business logic
* Converts service types to handler types for JSON serialization
- UpdatePreferences: Saves dashboard preferences
* Validates library_id
* Upserts user dashboard preferences
- RestoreSystemCollection: Resets system collection to defaults
* Validates collection_name against allowed system collections
* Deletes user's copy (system collection reappears automatically)
- BuildSections: Converts service DashboardSection to handler SectionData
* Converts database.MediaItems to handlers.BookInfo
* Uses shared types from collections.go
- getViewAllURL: Maps system collections to their view-all URLs
- Reuses existing textToString helper from collections.go
Architecture Compliance:
- Generic API handler for reuse by SSR, mobile, plugins
- Uses shared types from collections.go (SectionData, BookInfo)
- IsSystem bool matches database field (no string conversion)
- Single service method returns structured data (simpler, less bugs)
- Handler just converts types (no matching logic needed)
- Reusable by mobile apps, web UI, plugins
Convert tags and contributors columns from comma-separated strings to PostgreSQL
TEXT[] arrays for better data normalization and query performance.
Database Changes:
- schema.sql: Change tags/contributors from TEXT to TEXT[]
- schema.sql: Add GIN indexes for fast array searches
- queries.sql: Update search queries to use ANY() operator
- queries.sql: Update fuzzy search with unnest() for arrays
Generated Code (sqlc):
- models.go: Auto-generated with []string types for tags/contributors
- queries.sql.go: Auto-generated with proper array handling
Handler Changes:
- media.go: Update request structs to use []string for tags/contributors
- media.go: Remove pgtype.Text wrapping, use direct array assignment
- media.go: Add tag normalization in CreateMediaItemHandler
- collections.go: Update tags evaluation to join arrays for comparison
- collections.go: Add strings import for Join() function
Service Changes:
- ebook_scanner.go: Update EbookMetadata struct to use []string
- ebook_scanner.go: Remove string Join(), assign arrays directly
- collection_service.go: Update tags rule evaluation to join arrays
- collection_service.go: Add strings import
New Utilities:
- internal/utils/tags.go: Create NormalizeTags(), JoinTags(), SplitTags()
- Normalizes tags by trimming, lowercasing, removing duplicates/empties
API Documentation:
- bruno/media-items/Create Media Item.bru: Update examples to use arrays
- bruno/media-items/Update Media Item.bru: Update examples to use arrays
- Update docs: tags/contributors now array of string
Breaking Change:
- JSON format changes from "tags": "tag1,tag2" to "tags": ["tag1", "tag2"]
- Tests already use array format (no changes needed)
Benefits:
- GIN indexes enable faster array searches
- Normalization prevents data quality issues (case, duplicates)
- Array operations use PostgreSQL native operators (ANY, &&, unnest)
- Better separation of concerns (no string parsing in application)
Implement real-time collection updates when books are added/removed:
Backend Changes:
- Added connManager to CollectionHandler struct
- Updated constructor to accept ConnectionManager
- Updated all NewCollectionHandler() calls in ebook.go and main.go
- Added WebSocket broadcasts in AddBooks() handler
- Added WebSocket broadcasts in BulkRemoveBooks() handler
- Broadcasts collection_updated events with:
- collection_id: Which collection changed
- action: books_added or books_removed
- book_ids: Array of affected book IDs
- count: Number of books changed
Frontend Changes:
- Added WebSocket connection in collections UI
- connectWebSocket() establishes connection to /ws/sync
- Listens for collection_updated events
- Shows toast notification on collection change
- Auto-reloads page after 1 second to show updated book list
- Auto-reconnect on disconnect (5s delay)
- Error handling for WebSocket failures
WebSocket Event Format:
{
"type": "collection_updated",
"timestamp": "2026-02-01T12:00:00Z",
"data": {
"collection_id": "uuid",
"action": "books_added",
"book_ids": ["uuid1", "uuid2"],
"count": 2
}
}
User Experience:
- When another user adds books to a collection, all connected clients see:
1. Toast notification: "Collection updated: books_added (2 books)"
2. Page auto-refreshes after 1 second
3. Updated book list displays
- Same for book removal
- Works across multiple browser tabs/devices
- No manual refresh needed
Technical Notes:
- Broadcasts to ALL connected WebSocket clients
- Client-side filtering by collection_id
- Existing progress/conflict broadcasts continue to work
- Connection manager handles broadcast distribution
Resolves Limitation #4: Real-time Collection Updates
Complete bulk operations for collections management:
BULK ADD BOOKS:
- Implemented searchBooks() with real API integration
- Multi-select checkboxes for book selection
- SelectedBooks Set tracks chosen books
- AddSelectedBooks() sends array to existing endpoint
- Uses existing POST /api/collections/:id/books endpoint
BULK REMOVE BOOKS:
- New endpoint: POST /api/collections/:id/books/bulk-remove
- Checkboxes on each book card for selection
- BooksToRemove Set tracks selections
- Live counter showing selected count
- BulkRemoveBooks() handler removes all in one API call
- More efficient than N individual DELETE requests
Frontend Changes:
- Selected counter badge shows number selected
- Bulk remove button (enabled when books selected)
- Checkboxes on all books for multi-select
- Confirmation dialog for bulk operations
- Toast notifications with counts
Backend Changes:
- BulkRemoveBooks() handler in collections.go
- Accepts book_ids array, returns removed/total counts
- Iterates and removes, counting successes
- Route: POST /api/collections/:id/books/bulk-remove
API Request:
{
"book_ids": ["uuid1", "uuid2", "uuid3"]
}
API Response:
{
"removed": 3,
"total": 3
}
Tests Added:
- TestCompareValues_* (existing)
- TestEvaluateRule_* (existing)
Resolves Limitations #2 (Bulk Operations) and #5 (Bulk Remove)
Add data retrieval helpers for SSR template rendering:
- GetDeviceMappingsData: Fetch device shelf mappings for device settings UI
- GetUserCollectionsList: Get all user collections for dropdowns and listings
- GetCollectionData: Get single collection with metadata
- GetCollectionBooksData: Get books in a collection
These functions support the Phase 9 frontend features by providing
efficient data access for template rendering without modifying
existing API endpoints.
- Add OPDS handler for device catalog and book downloads
- Add collections handler for collection CRUD
- Add book matching service for cross-device book linking
- Add sidecar handler for Kobo metadata sync
- Add sync handler for device synchronization
