# Web UI Library Reads — Design
**Status:** approved (2026-04-20)
**Follows:** `2026-04-20-web-ui-scaffold-design.md`, `2026-04-20-web-ui-server-auth-foundation` (shipped)
**Precedes:** Plan 3 — stream + cover endpoints
## Goal
Add the read-only library surface to Minstrel's native JSON API at `/api/*`. Five endpoints: paginated artist list (two sort modes), artist detail, album detail, track detail, and unified search. This is the data the SvelteKit SPA needs to render browse and search views; streaming and cover art follow in Plan 3.
Scope explicitly excludes: stream, cover, write operations (favorites, play history), admin endpoints beyond what's already mounted.
## Routes
All gated by the existing `RequireUser` middleware inside `api.Mount`:
```
GET /api/artists?sort={alpha|newest}&limit=&offset=
GET /api/artists/{id}
GET /api/albums/{id}
GET /api/tracks/{id}
GET /api/search?q=&limit=&offset=
```
Path-style IDs (chi `{id}`) — matches REST norms and the SPA router's expectations. Pagination defaults: `limit=50`, `limit` clamped to `[1,200]`, `offset=0`, `offset` clamped to `>=0`. Out-of-range values silently clamp (match subsonic ergonomics); malformed values (non-numeric) return 400.
## Response Shapes
Two-tier Ref/Detail split mirrors the subsonic package's pattern.
### Refs
Lightweight, embedded in list and detail responses.
```go
type ArtistRef struct {
ID string `json:"id"` // UUID string
Name string `json:"name"`
AlbumCount int `json:"album_count"`
}
type AlbumRef struct {
ID string `json:"id"`
Title string `json:"title"`
ArtistID string `json:"artist_id"`
ArtistName string `json:"artist_name"`
Year int `json:"year,omitempty"`
TrackCount int `json:"track_count"`
DurationSec int `json:"duration_sec"`
CoverURL string `json:"cover_url"` // /api/albums/{id}/cover — lands in Plan 3
}
type TrackRef struct {
ID string `json:"id"`
Title string `json:"title"`
AlbumID string `json:"album_id"`
AlbumTitle string `json:"album_title"`
ArtistID string `json:"artist_id"`
ArtistName string `json:"artist_name"`
TrackNumber int `json:"track_number,omitempty"`
DiscNumber int `json:"disc_number,omitempty"`
DurationSec int `json:"duration_sec"`
StreamURL string `json:"stream_url"` // /api/tracks/{id}/stream — Plan 3
}
```
### Details
Wrap a ref with nested children.
```go
type ArtistDetail struct {
ArtistRef
Albums []AlbumRef `json:"albums"`
}
type AlbumDetail struct {
AlbumRef
Tracks []TrackRef `json:"tracks"`
}
// Track detail is just TrackRef — parent names are already embedded.
```
### Pagination Envelope
Shared generic, defined once in `types.go`:
```go
type Page[T any] struct {
Items []T `json:"items"`
Total int `json:"total"`
Limit int `json:"limit"`
Offset int `json:"offset"`
}
```
Used by `/api/artists` and each facet of `/api/search`.
### Search Response
Three independent paged facets sharing one `limit`/`offset`:
```go
type SearchResponse struct {
Artists Page[ArtistRef] `json:"artists"`
Albums Page[AlbumRef] `json:"albums"`
Tracks Page[TrackRef] `json:"tracks"`
}
```
Shared limit/offset (vs subsonic's per-facet params) keeps the SPA simple: one set of pager controls per search page.
### JSON conventions
- UUIDs serialize as strings (not `pgtype.UUID`) via a `uuidToString` helper in `convert.go`.
- Empty collections always render as `[]`, never `null` — web clients reject null. Initialize slices explicitly before encoding.
- Field names: snake_case everywhere.
## Embedded URLs
Forward-reference URLs baked into responses now, even though Plan 3 implements the endpoints:
- `AlbumRef.CoverURL` = `/api/albums/{id}/cover`
- `TrackRef.StreamURL` = `/api/tracks/{id}/stream`
Built by helpers in `convert.go`:
```go
func coverURL(albumID pgtype.UUID) string { return "/api/albums/" + uuidToString(albumID) + "/cover" }
func streamURL(trackID pgtype.UUID) string { return "/api/tracks/" + uuidToString(trackID) + "/stream" }
```
Relative paths — SPA and Flutter client resolve against configured base URL. Responses stay host-agnostic (reverse-proxy friendly). Until Plan 3, these paths 404; the SPA won't wire `<audio src>` / `<img src>` until Plan 3 ships.
## SQL Queries
All SELECT-only. No migrations. Add to `internal/db/queries/`:
### artists.sql
```sql
-- name: ListArtistsAlpha :many
SELECT * FROM artists ORDER BY sort_name, name LIMIT $1 OFFSET $2;
-- name: ListArtistsNewest :many
SELECT * FROM artists ORDER BY created_at DESC, id DESC LIMIT $1 OFFSET $2;
-- name: CountArtists :one
SELECT COUNT(*) FROM artists;
-- name: CountArtistsMatching :one
SELECT COUNT(*) FROM artists WHERE name ILIKE '%' || $1::text || '%';
```
`ListArtists` (no LIMIT) stays — subsonic's `buildArtistIndexes` still needs it. Don't rewrite that call site; add paginated siblings.
### albums.sql
```sql
-- name: CountAlbumsMatching :one
SELECT COUNT(*) FROM albums WHERE title ILIKE '%' || $1::text || '%';
```
`SearchAlbums` already exists; it just needed the count sibling.
### tracks.sql
```sql
-- name: CountTracksMatching :one
SELECT COUNT(*) FROM tracks WHERE title ILIKE '%' || $1::text || '%';
```
### Notes
- Secondary ordering (`created_at DESC, id DESC`) gives newest sort a stable tiebreaker — prevents pagination drift when two artists share a timestamp.
- Two-query pattern (list + count) is acceptable at M1 sizes (thousands of rows). Revisit with window functions if artists exceed ~100k.
Regenerate sqlc output (`go generate ./...` or the Makefile step) to refresh `internal/db/dbq/*.go`.
## Data Flow
### `GET /api/artists?sort=alpha`
1. Parse `limit`/`offset`/`sort` from query; clamp and default.
2. `q.ListArtistsAlpha` or `q.ListArtistsNewest` (pick by `sort`).
3. `q.CountArtists` for `total`.
4. For each artist, `q.ListAlbumsByArtist``album_count`. N+1, but at `limit=50` acceptable. Revisit with a join query if profiling flags it.
5. Build `Page[ArtistRef]`, JSON-encode.
### `GET /api/artists/{id}`
1. Parse `{id}` as UUID (400 on bad form).
2. `GetArtistByID` (404 on `pgx.ErrNoRows`).
3. `ListAlbumsByArtist(id)` → album list.
4. For each album, `CountTracksByAlbum` (consistent with subsonic; cheap).
5. Return `ArtistDetail` with embedded `[]AlbumRef`.
### `GET /api/albums/{id}`
1. Parse `{id}` as UUID (400).
2. `GetAlbumByID` (404).
3. `GetArtistByID(album.ArtistID)` for artist name.
4. `ListTracksByAlbum(id)` → ordered by disc/track number at the query level (existing behavior).
5. Return `AlbumDetail` with embedded `[]TrackRef`.
### `GET /api/tracks/{id}`
1. Parse `{id}` as UUID (400).
2. `GetTrackByID` (404).
3. `GetAlbumByID(track.AlbumID)` + `GetArtistByID(track.ArtistID)` for parent names.
4. Return `TrackRef` directly (no wrapping detail type — all fields already present).
### `GET /api/search?q=foo`
1. Parse `q` (empty → 400), `limit`, `offset`.
2. Serial: `SearchArtists` + `CountArtistsMatching``Page[ArtistRef]`.
3. Serial: `SearchAlbums` + `CountAlbumsMatching``Page[AlbumRef]` (resolve artist names inline).
4. Serial: `SearchTracks` + `CountTracksMatching``Page[TrackRef]` (resolve album + artist names inline).
5. Return `SearchResponse`.
### Artist-name resolution in album lists
Reuse the pattern from subsonic's `resolveArtistNames`: one query per distinct artist id in the page. For a 50-album page this is ≤50 but typically fewer (same artist repeated). Duplicate the pattern inline in `internal/api` rather than importing from subsonic — tiny helper, clean package boundary.
## Error Handling
Reuse existing `writeErr(w, code, slug, message)` from `internal/api/errors.go`. The SPA's auth code already parses the `{error:{code,message}}` envelope.
| Condition | HTTP | code slug |
|---|---|---|
| No cookie/bearer | 401 | `unauthorized` (from `RequireUser`) |
| Malformed UUID in path | 400 | `bad_request` |
| Row not found | 404 | `not_found` |
| Missing `q` on search | 400 | `bad_request` |
| `limit`/`offset` non-numeric | 400 | `bad_request` |
| DB / query failure | 500 | `server_error` (logged; message generic) |
Out-of-range `limit`/`offset` silently clamp (not 400). Matches subsonic's `clampInt` ergonomics and means the SPA can send whatever value the user picks without validation.
## File Structure
Files to create:
| File | Responsibility |
|---|---|
| `internal/api/library.go` | Artist/album/track list and detail handlers |
| `internal/api/search.go` | Unified search handler |
| `internal/api/convert.go` | uuid↔string, year-from-pgdate, URL builders |
| `internal/api/library_test.go` | Integration tests for library endpoints |
| `internal/api/search_test.go` | Integration tests for search |
| `internal/api/library_fixtures_test.go` | Shared seed helpers (`seedArtist`, `seedAlbum`, `seedTrack`) |
Files to modify:
| File | Change |
|---|---|
| `internal/api/api.go` | Register new routes inside the `authed` group |
| `internal/api/types.go` | Add `Page[T]`, refs, details, `SearchResponse` |
| `internal/db/queries/artists.sql` | Add list + count queries |
| `internal/db/queries/albums.sql` | Add `CountAlbumsMatching` |
| `internal/db/queries/tracks.sql` | Add `CountTracksMatching` |
Regenerated: `internal/db/dbq/artists.sql.go`, `albums.sql.go`, `tracks.sql.go`.
Approach A was chosen during brainstorming: fresh handlers in `internal/api`, tiny helpers duplicated inline. No shared package with subsonic. The two packages shape responses differently (subsonic wraps in `subsonic-response`; api returns bare JSON envelopes), and the duplicated helpers are ~5 lines each. Revisit extraction during Plan 3 if stream/cover surfaces real duplication.
## Testing
Integration-only, following the `auth_test.go` pattern:
- `testHandlers(t)` helper already exists (spins handlers against `MINSTREL_TEST_DATABASE_URL`, TRUNCATE between tests).
- `library_fixtures_test.go` adds `seedArtist`, `seedAlbum`, `seedTrack` shared across library + search tests.
- No unit tests for `convert.go` helpers — trivial, covered through handler tests.
### Key test cases per endpoint
**`GET /api/artists`:**
- default sort = alpha, paged correctly
- `sort=newest``created_at DESC` order
- `sort=garbage` → 400
- `limit`/`offset` respected, `total` reflects full count
- embedded `album_count` matches fixture
**`GET /api/artists/{id}`:**
- happy path with nested albums
- bad UUID → 400
- unknown UUID → 404
**`GET /api/albums/{id}`:**
- happy path with tracks + artist name + `cover_url` embedded
- tracks ordered by disc/track number
- 400 / 404 parity
**`GET /api/tracks/{id}`:**
- happy path with parent names + `stream_url` embedded
- 400 / 404
**`GET /api/search?q=foo`:**
- three paged facets populated
- empty `q` → 400
- no matches → three `[]` facets, totals = 0
- shared `limit`/`offset` applied per facet
- each facet's `total` reflects full match count
### Explicitly out of scope for tests
- Concurrency / race conditions
- Large-result performance (N+1 tolerance, profiling)
- Stream/cover endpoint behavior (Plan 3)
## Out of Scope (Plan 3 or later)
- `GET /api/tracks/{id}/stream` — audio delivery with range requests
- `GET /api/albums/{id}/cover` — cover art delivery
- Favorites, play history, playlists
- Admin endpoints (scan, user management)
- Multi-library support
- Subsonic client shim (separate track)

# Web UI Media Endpoints — Design Spec
**Date:** 2026-04-21
**Status:** Design approved
**Follows:** [Web UI Library Reads](2026-04-20-web-ui-library-reads-design.md) — this spec implements the `cover_url` and `stream_url` forward references shipped in Plan 2.
## Goal
Ship the two byte-serving endpoints the web SPA (and later the Flutter client) need to render album art and play tracks. When this lands, every `<img src>` and `<audio src>` tag that Plan 2's DTOs produced will resolve.
## Non-goals
Explicit YAGNI — documented here so they don't drift back in during implementation:
- No cover resizing (`?size=` param). Serving one size matches subsonic's current behavior; re-sizing is a future optimization when the SPA shows it's needed.
- No audio transcoding (`?format=`, `?maxBitRate=`). Raw bytes only.
- No `/download` attachment-mode variant. `/stream` is enough for the SPA; a separate download endpoint can land later if a concrete caller needs it.
- No scanner changes to populate `albums.cover_art_path`. The sidecar fallback covers the common real-world case today; improving scanner coverage is its own plan.
## Architecture
Two endpoints, both under `RequireUser` in the existing `/api` Mount:
- `GET /api/albums/{id}/cover` → album cover image
- `GET /api/tracks/{id}/stream` → raw audio bytes, Range-capable
**Package isolation.** `internal/subsonic/stream.go` already implements the same two behaviors for `/rest/*`. Per project direction, subsonic is long-term legacy and stays frozen. The protocol-agnostic helpers (mime tables, sidecar lookup, `http.ServeContent` glue) are duplicated into `internal/api/media.go` rather than extracted into a shared package. The only shared layer is `internal/db/dbq` (already) and `http.ServeContent` from stdlib.
**Auth.** No new middleware. `auth.RequireUser` (in `internal/auth/session.go`) already accepts both the `minstrel_session` cookie and `Authorization: Bearer <token>`. Browser `<img>` and `<audio>` tags send cookies automatically; the Flutter client will carry the bearer token.
**Range / ETag / If-Modified-Since.** Delegated to `http.ServeContent`, which reads headers from the request and writes the correct 206/304/200 response plus `Content-Range` / `ETag` / `Last-Modified`. No hand-rolled Range parsing.
## Routes
| Method | Path | Auth | Success response |
|---|---|---|---|
| GET | `/api/albums/{id}/cover` | `RequireUser` | 200 (or 304) with image bytes; `Content-Type` inferred from file extension (`image/jpeg`, `image/png`, `image/webp`, `image/gif`) |
| GET | `/api/tracks/{id}/stream` | `RequireUser` | 200 / 206 / 304 with audio bytes; `Content-Type` from `track.file_format` (e.g. `audio/mpeg`, `audio/flac`, `audio/ogg`); `Accept-Ranges: bytes`; `Content-Length` set by `http.ServeContent` |
Both routes register inside the existing `authed` chi group in `internal/api/api.go` (alongside the Plan 2 library routes). Production `Mount` wires them; the test-only `newLibraryRouter` helper is extended to include them so integration tests can exercise the routes end-to-end.
## Data flow
### `GET /api/albums/{id}/cover`
1. Parse `{id}` via `parseUUID` (the helper from `internal/api/convert.go`). Malformed UUID → 400 `bad_request` "invalid album id".
2. `q.GetAlbumByID(ctx, id)`. `pgx.ErrNoRows` → 404 `not_found` "album not found". Other err → 500 `server_error`.
3. `resolveAlbumCoverPath(ctx, q, album)`:
- If `album.CoverArtPath != nil` and the file stats successfully, return that path.
- Otherwise, list tracks for the album (`q.ListTracksByAlbum`, which orders by disc/track number). For the first track in that ordered result, look in its directory for `cover.jpg`, `cover.jpeg`, `cover.png`, `folder.jpg`, `folder.jpeg`, `folder.png` in that order. Return the first file that exists; else return `""`.
4. Empty path return → 404 `not_found` "cover not found".
5. `os.Open` + `f.Stat`. File vanished since resolve → 404 `not_found` "cover not found". Stat err → 500.
6. Set `Content-Type` from `imageContentType(path)` (file-extension-based mapping). Call `http.ServeContent(w, r, filepath.Base(path), info.ModTime(), f)`.
### `GET /api/tracks/{id}/stream`
1. Parse `{id}`. Malformed UUID → 400 `bad_request` "invalid track id".
2. `q.GetTrackByID(ctx, id)`. `pgx.ErrNoRows` → 404 `not_found` "track not found". Other err → 500.
3. `os.Open(track.FilePath)`. File vanished → 404 `not_found` "track file not found". Other err → 500.
4. `f.Stat`. Err → 500.
5. Set `Content-Type` from `audioContentType(track.FileFormat)`. Set `Accept-Ranges: bytes`. Call `http.ServeContent(w, r, filepath.Base(track.FilePath), info.ModTime(), f)`.
## Error shape
All errors use the existing `writeErr` helper → `{"error":{"code":"...","message":"..."}}`, matching the rest of `/api/*`. Codes reused from Plan 2: `bad_request`, `not_found`, `server_error`.
| Condition | Status | Code | Message |
|---|---|---|---|
| Malformed UUID in path | 400 | `bad_request` | `invalid album id` / `invalid track id` |
| Unknown album / track | 404 | `not_found` | `album not found` / `track not found` |
| Album has no resolvable cover | 404 | `not_found` | `cover not found` |
| Track file missing on disk | 404 | `not_found` | `track file not found` |
| DB lookup failure | 500 | `server_error` | `server error` |
| `os.Stat` failure on known path | 500 | `server_error` | `server error` |
## Components
Single new file: `internal/api/media.go`. Contains both handlers and their duplicated helpers.
```
handlers
handleGetCover(w, r)
handleGetStream(w, r)
free functions (package-private)
resolveAlbumCoverPath(ctx, q, album) string
findSidecarCover(trackDir string) string
audioContentType(format string) string
imageContentType(path string) string
```
`audioContentType` table (mirrors subsonic's `contentTypeForFormat`, duplicated verbatim):
| file_format | Content-Type |
|---|---|
| `mp3` | `audio/mpeg` |
| `flac` | `audio/flac` |
| `ogg` | `audio/ogg` |
| `opus` | `audio/ogg` |
| `m4a` | `audio/mp4` |
| `aac` | `audio/aac` |
| `wav` | `audio/wav` |
| *(other)* | `application/octet-stream` |
`imageContentType` table:
| extension (lowercase) | Content-Type |
|---|---|
| `.jpg`, `.jpeg` | `image/jpeg` |
| `.png` | `image/png` |
| `.webp` | `image/webp` |
| `.gif` | `image/gif` |
| *(other)* | `application/octet-stream` |
Sidecar lookup order (first match wins):
```
cover.jpg, cover.jpeg, cover.png,
folder.jpg, folder.jpeg, folder.png
```
## Testing
Integration tests in `internal/api/media_test.go`. They reuse the existing `testHandlers(t)`, `truncateLibrary(t, pool)`, `seedArtist`, `seedAlbum`, `seedTrack` helpers from `library_fixtures_test.go`, and add a new helper:
- `seedTrackWithFile(t, pool, albumID, artistID, title string, fileBody []byte, ext string) (dbq.Track, string)` — writes `fileBody` into `t.TempDir()` with the given extension, inserts a Track row whose `file_path` points at it, returns the track and the dir.
### Cover tests
- **Happy path (sidecar):** seed album + track, drop a known-bytes `cover.jpg` in the track's dir. GET cover → 200, `Content-Type: image/jpeg`, body equals the file bytes.
- **Happy path (explicit `cover_art_path`):** seed album with `cover_art_path` pointing at a separate image file (no sidecar). GET → 200 with the right file's bytes.
- **Explicit path missing on disk falls through to sidecar:** set `cover_art_path` to a non-existent path, drop a sidecar. GET → 200 with the sidecar bytes.
- **No art anywhere:** seed album + track, no sidecar, no `cover_art_path`. GET → 404 `not_found` "cover not found".
- **Bad UUID:** `GET /api/albums/not-a-uuid/cover` → 400 `bad_request` "invalid album id".
- **Unknown album:** `GET /api/albums/<random UUID>/cover` → 404 `not_found` "album not found".
- **Content-Type per extension:** table-driven test invoking `imageContentType` on `.jpg`, `.jpeg`, `.png`, `.webp`, `.gif`, and a bogus extension.
### Stream tests
- **Happy path:** seed track with a known-bytes payload (32 KB of random-but-fixed bytes, `.mp3` extension, `file_format="mp3"`). GET → 200, `Content-Type: audio/mpeg`, `Accept-Ranges: bytes`, body equals the file bytes, `Content-Length` matches.
- **Range request:** `Range: bytes=0-99` → 206 Partial Content, body is exactly the first 100 bytes, `Content-Range: bytes 0-99/32768`.
- **Range at end:** `Range: bytes=32000-` → 206, body is the tail, `Content-Range: bytes 32000-32767/32768`.
- **If-Modified-Since pass-through:** second GET with `If-Modified-Since` set to the file's mod time → 304.
- **Bad UUID:** `GET /api/tracks/not-a-uuid/stream` → 400 `bad_request` "invalid track id".
- **Unknown track:** random UUID → 404 `not_found` "track not found".
- **Vanished file:** seed track pointing at `filepath.Join(tempDir, "does-not-exist.mp3")` → 404 `not_found` "track file not found".
- **Content-Type per format:** table-driven test invoking `audioContentType` on all seven known formats plus `"unknown"`.
### Route registration regression
Extend `TestRoutesRegisteredInMount` (from Plan 2's Task 11) to also assert the two new paths return 401 (not 404) unauthenticated:
```
"/api/albums/00000000-0000-0000-0000-000000000001/cover",
"/api/tracks/00000000-0000-0000-0000-000000000001/stream",
```
## File structure
| File | Change | Purpose |
|---|---|---|
| `internal/api/media.go` | Create | Both handlers + locally-duplicated helpers |
| `internal/api/media_test.go` | Create | Integration tests for both endpoints, unit tests for mime helpers |
| `internal/api/library_fixtures_test.go` | Modify | Add `seedTrackWithFile` helper |
| `internal/api/api.go` | Modify | Register both new routes inside the `authed` group in `Mount` |
| `internal/api/library_test.go` | Modify | Extend `TestRoutesRegisteredInMount` to include the two new paths; extend the `newLibraryRouter` helper to register the media routes so integration tests can exercise them through the same test harness |
No migrations. No new sqlc queries (existing `GetAlbumByID`, `GetTrackByID`, `ListTracksByAlbum` are sufficient). No package-level dependencies beyond the stdlib and what `/api` already imports.
## Success criteria
- Both endpoints reachable through the production `Mount` under `RequireUser`.
- Browser `<img src="/api/albums/{id}/cover">` renders the art (or triggers `onerror` cleanly on 404).
- Browser `<audio src="/api/tracks/{id}/stream">` plays and can seek (verifies Range).
- Integration test suite green, no flakes.
- Manual smoke: log in, curl each endpoint, verify returns + Range behavior.
- PR merges to `main` via the existing `dev``main` flow.
