ApiTrackLike/QueueItem had no duration field, so toQueueItem(s) always dropped it and toTrack() hardcoded a new track's duration to 0, relying entirely on the <audio> element's durationchange/loadedmetadata events to fill it in once that track actually became current. Upcoming queue rows never reach that point, so "A continuación" always showed a blank duration even though the backend already returns it. Add duration to both types, thread it through toQueueItems/toQueueItem/ trackFromQueueItem, and seed toTrack() from it. The real-time audio sync still overwrites it once a track actually plays, so this only fills the gap for tracks that haven't played yet. Also map MixItemApplicationResponse's durationSeconds through mixItemTrack, since mixes use a differently-named field.
web-player
Musify's web client: SvelteKit 2 (adapter-node), Svelte 5 runes, Tailwind 4,
TypeScript. Authentication is server-side OIDC against Zitadel (openid-client
and jose) with an encrypted session cookie; the backend is called from load
functions and form actions through a typed openapi-fetch client.
Development
npm install
npm run dev # :5173
Configuration lives in .env (template in .env.example). Bring the
infrastructure stack up first (see ../deploy/README.md)
and copy the WEB_CLIENT_ID / WEB_CLIENT_SECRET it writes to deploy/.env
into this .env once, then run the dev server.
npm run check # svelte-check — must be clean before closing a change
npm run lint # prettier --check . && eslint .
npm run format # prettier --write .
npm run build # production build into build/
npm run gen:api # regenerate src/lib/api/schema.d.ts from the running API
Production
Built and run as a container by the production stack — see
../deploy/README.md. There the same variables come from
deploy/.env.prod through compose instead of from .env.
Conventions and the design system are documented in CLAUDE.md and
in the musify-web skill.
