Add gauge widget (recharts RadialBarChart with configurable threshold
bands, scalar-only per SC-111) and mean widget (client-side average over
range-query window, scalar-only per SC-114). Extract shared _instant_query
helper from the metric path; _fetch_gauge and _fetch_mean dispatch in
PrometheusWidgetSource.fetch(). Both new widget kinds declared in
integrations/prometheus.py and frontend registry.
Backend: 305 pytest pass, ruff clean. Frontend: 136 vitest pass, build+lint green.
The iframe-based 'panel' widget didn't work: the browser couldn't
authenticate against the OIDC-protected Grafana (Authentik), and
iframes can't carry Bearer tokens or share cross-origin session
cookies. Result: blank iframe or login redirect.
Replace it with a 'chart' widget that queries Grafana's datasource
API server-side:
Backend (GrafanaWidgetSource): POSTs to /api/ds/query with the stored
api_key (which bypasses OIDC), using the widget's configured PromQL
query, datasource_uid, time range, and resolution. Normalizes Grafana's
frame-based response into a simple {series: [{label, points: [{t, v}]}]}
shape. The api_key is never exposed to the browser.
Frontend (GrafanaChartWidget): renders the series data as a recharts
LineChart with dark-mode-aware colors (Tailwind --chart-* tokens),
responsive container, custom tooltip, and per-series lines. Loading
skeleton, error Alert, and empty state. recharts ^3.9.2 added.
The 'link' widget kind (deep-link URL) is unchanged. The 'panel' kind
and GrafanaPanelWidget are fully removed.
Backend: 279 tests pass (+1 net: -2 panel + 3 chart). Frontend: 127
tests pass (net 0: -3 panel + 3 chart). Lint/build green both sides.
Two new additive widget kinds:
Jellyfin 'now_playing': like the existing 'activity' widget but filters
to only sessions with active playback (NowPlayingItem present + not
paused). Shows who's actually watching right now. The 'activity' kind
is unchanged (shows all sessions including idle).
Grafana 'panel': embeds a single Grafana panel directly in the app via
an iframe, using Grafana's /d-solo/ endpoint (renders one panel without
dashboard chrome, kiosk=tv). Configurable dashboard_uid, panel_id, and
time range (from/to, defaults now-1h/now). Includes a fallback 'Open in
Grafana' link for when embedding is blocked by X-Frame-Options/CSP. The
'link' kind is unchanged (still builds a deep-link URL).
Backend: new widget configs + definitions on jellyfin/grafana; source
adapter logic (session filter for now_playing; d-solo embed URL for
panel); 6 new tests.
Frontend: JellyfinNowPlayingWidget + GrafanaPanelWidget components;
registry bindings; 6 new tests.
278 backend tests pass (+6); 127 frontend tests pass (+6); lint/build
green both sides.
PR 3 of 4 for the runtime service registry change.
- Add service + new-shape widget TypeScript types; widgets carry service_id
+ widget_kind (service-bound) or null (built-in).
- Add services API client + TanStack Query hooks; reconcile the widget API
client/hooks to the new endpoints (remove sources/types; add builtin kinds).
- Add closed frontend service registry (integrations/registry.ts) mirroring the
backend, with resolveWidget(widget, services) mapping a widget to its
component + refresh interval.
- Add ServicePage at /services/:serviceType/:serviceId with config view,
empty-on-edit secret inputs + 'set' badges, enable toggle, delete, and the
service's widget-kind list.
- Register /services/:serviceType/:serviceId in App.tsx.
- Reconcile the six widget components to refreshIntervalMs + description props;
rewrite WidgetConfigDialog around a service -> widget-kind picker.
- Update Dashboard test; add integrations/registry.test.ts.
Verification: frontend lint 0 errors, build success, 70 tests passed; backend
ruff clean, 222 tests passed.
