Two fixes for the Grafana chart widget: 1. Invisible lines: the CHART_COLORS used 'hsl(var(--chart-1))' but the CSS variable is named '--color-chart-1' and already contains a hex color (#4f8cff). The hsl() wrapper produced invalid CSS, making every stroke invisible. Fixed to var(--color-chart-1). 2. Multiple series collision: the backend labeled all Prometheus series with the value field name (often just 'Value'), so multiple time series collided on the same recharts dataKey and overwrote each other. Now extracts meaningful labels from the Grafana frame metadata: prefers displayName, then Prometheus metric labels (e.g. 'instance=server1:9100 mode=iowait'), then falls back to the field name. Duplicate labels get a numeric suffix for uniqueness. Multi-series queries now render correctly: each Prometheus time series gets its own colored line with a unique label in the legend/tooltip. 280 backend tests pass (+1 labels test); 127 frontend tests pass; ruff/ eslint clean.
Manage Frontend
React + TypeScript SPA for Manage, consuming the FastAPI backend.
Tech Stack
- Vite — Build tool
- React 18+ — UI framework
- TypeScript — Type safety
- @tanstack/react-query — Data fetching/caching
- @tanstack/react-table — Data tables (media, file browser)
- react-router-dom — Client-side routing
- Tailwind CSS + shadcn/ui — Styling
Setup
cd frontend
npm install
Development
npm run dev
Runs on http://localhost:5173 with API requests proxied to http://localhost:8000.
Make sure the backend is running:
cd ../backend
uvicorn media_library_viewer_api.main:app --reload --port 8000
Build
npm run build
Output goes to frontend/dist/.
Pages
- Dashboard (
/) — Now playing, library stats, configurable widgets and shortcuts, frontend/backend version chips in the shell header - Observability (
/observability) — Thin dashboard: Alertmanager alerts, Prometheus target health, machine status, and Grafana deep-links (no in-app charting) - Media (
/media) — Full-library table with sort/filter/search - Users (
/users) — Read-only Jellyfin user list with optional Jellyseerr enrichment - File Browser (
/files) — Remote directory browsing, ffprobe preview, jobs - Settings (
/settings) — Persistent monitoring machine definitions, SSH keys, and setup workflow - Actions (
/actions) — Saved server tasks (shell/python) targeting ssh_tasks services
Environment Variables
Set VITE_API_URL and any OIDC variables directly in your shell or Compose build args if the API is not at http://localhost:8000.
The frontend version defaults to the package.json version and can be overridden with VITE_APP_VERSION and VITE_APP_BUILD_INFO when you need explicit deployed labels.
VITE_API_URL=http://your-backend-host:8000
Configuration workflow examples
- Local development: run
docker compose -f docker-compose.dev.yml up --build, then open the app and add monitoring machines in the Settings tab. - Production: export the required Compose variables in your shell, run
docker compose up --build, and manage local/remote machines from Settings. - Observability: Manage only deploys backend + frontend. It connects to existing Grafana/Prometheus/Alertmanager instances; see
docker-compose.observability.ymlfor an optional standalone example stack. A machine can belocal(the API host itself) orssh(a remote host), and the UI treats both the same after configuration.
In development, the Vite proxy handles /api requests automatically. Observability services (Grafana, Prometheus, Alertmanager) are configured in the app on the Services page — there are no observability env vars.
