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.
Backend:
- FastAPI app with 17 REST endpoints covering dashboard, monitoring,
media index, file browser, and jobs
- Reuses existing clients/domain/services unchanged
- pydantic-settings config, dependency injection, CORS setup
- Auto-generated OpenAPI docs at /docs
Frontend:
- Vite + React + TypeScript SPA
- @tanstack/react-query for data fetching with polling
- ag-grid-react for media table and file browser
- recharts for monitoring charts
- Tailwind CSS styling
- 4 pages: Dashboard, Monitoring, Media, File Browser
- Typed API client matching all backend endpoints
Also:
- docs/MIGRATION_PLAN.md with full architecture plan
- Updated .gitignore for both subprojects
- Streamlit app preserved for now (can coexist)
