Drops the YouTube-backed second catalog source entirely: the
Local/External split on Track/Album collapses into single concrete
entities, Artist/TrackArtist/ExternalTrack/ExternalAlbum and the
YouTube service/download pipeline (yt-dlp, MassTransit consumer,
routing slip) are deleted, and mixes now source discovery only from
local listening history. Includes the RemoveYouTubeIntegration EF
Core migration and matching Worker/deploy/compose cleanup (no more
yt-dlp/python/deno in the Worker image, no thumbnail-cache/YtDlp
config sections).
Backend:
- New Likes feature (toggle/get liked tracks) and endpoints
- User follow/unfollow, listening stats, public user profile
- Playlist visibility (public/private) support
- Various auth and DTO/response adjustments to support the above
Frontend (web-player):
- New design system pass: theme tokens/mode (light/dark), glass menu,
tabs bar, player dock/extras/queue components, mix tiles, artist link
- New routes: Liked, public user profile (/u/[id]), likes API proxy
- Search refactor: shared SearchBox component used by TopBar and
MobileHeader (search now reachable on mobile), live results as you
type instead of requiring Enter, dropped the "Buscando…" quick-result
preview
- Removed now-unused components (MobileNav, CoverBadge, MixBentoTile,
PlayPauseOverlay, SuggestionsTable, userDirectory)
- Design handoff reference docs added under web-player/design_handoff_musify_player
and web-player/docs/design-system-refactor-plan.md
AlbumApplicationResponse used to carry YouTubeAlbumId/ThumbnailUrl as
two always-present-but-usually-null fields for the sake of a single
flat shape. Since one of these fields IS genuinely exclusive to
external albums, an inheritance split reads better than the flattened
shape: AlbumApplicationResponse now holds only the fields shared by
every album, and ExternalAlbumApplicationResponse adds ExternalId
(renamed from YouTubeAlbumId, matching the source-generalized naming
used everywhere else) and ThumbnailUrl.
[JsonPolymorphic]/[JsonDerivedType] are required here, not optional:
without them System.Text.Json serializes strictly by the declared CLR
type at each call site (both the bare return type and nested inside
AlbumSearchItemResponse.Album), so an ExternalAlbumApplicationResponse
instance would silently lose its extra fields on the wire. This also
gives every response a "source" discriminator field for free,
consistent with AlbumSearchItemResponse.Source, and the generated
OpenAPI schema now models it as a proper oneOf/discriminator instead
of nullable fields.
Moves the six backend projects on disk into Core/ and Hosts/
subfolders, matching the solution folders already defined in
Musify.slnx, so the file explorer reflects the same layout as the
solution:
backend/Core/Musify.Domain
backend/Core/Musify.Application
backend/Core/Musify.Infrastructure
backend/Hosts/Musify.Api
backend/Hosts/Musify.Worker
backend/Hosts/Musify.StreamingGateway
Updates every reference to the old paths: ProjectReference entries in
Musify.Api.csproj and Musify.Worker.csproj, the three Dockerfiles,
deploy/scripts/migrate.ps1|sh, deploy/zitadel/provision.ps1,
deploy/up.ps1, deploy/README.md and docs/development.md. Also fixes a
stale Dockerfile comment pointing at a compose file that no longer
exists.
Verified with `dotnet build Musify.slnx` against the new layout.
