![example workflow](https://git.rivercry.com/wg/monitor-im-flur/actions/workflows/ci.yml/badge.svg)


### Project Structure (abridged)
```
src/
	api/              # External data fetchers
	components/       # UI building blocks (Cards, Timetable, Weather, Terminal, etc.)
	store/            # Zustand stores encapsulating fetch + state
	types/            # Type definitions for external data
pipeline/
	create-git-hash-html.sh  # Injects current commit hash into dist
Dockerfile          # Nginx static hosting
docker-compose.yml  # Example runtime service definition
```

### Environment Configuration
Create a `.env` (or `.env.local`) for Vite with the following (only what you need):
```
VITE_FLATTASTIC_API_KEY=your_flatastic_api_key
# (Planned) VITE_HOME_ASSISTANT_TOKEN=your_long_lived_token  # NOTE: currently hardcoded – see Security section
```

Vite automatically exposes variables prefixed with `VITE_` to the client bundle. Do NOT place secrets without that prefix – but remember: anything in the client bundle is public. For sensitive data consider a tiny proxy backend instead of calling APIs directly from the browser.

### Security Notice
`src/api/homeAssistant.ts` currently contains a hard‑coded long‑lived Home Assistant token. This should be refactored before any public deployment:
1. Remove the literal token from the repository.
2. Load it via environment variable during build (`import.meta.env.VITE_HOME_ASSISTANT_TOKEN`) OR
3. Prefer a minimal server proxy so the token never ships to the browser.

### Development
Install dependencies (Bun is inferred from `bun.lock`, but npm/pnpm/yarn also work).
```
bun install
```
Run the dev server (HTTPS support possible with `vite-plugin-mkcert` if certificates are trusted):
```
bun run dev
```
Open: http://localhost:5173

### Lint & Format
```
bun run lint
```
Optionally run Biome (if desired):
```
npx biome check --apply .
```

### Build
```
bun run build
```
Outputs production bundle to `dist/`.

### Docker Image
Build locally:
```
docker build -t monitor-im-flur:local .
```
Run:
```
docker run --rm -p 9123:80 monitor-im-flur:local
```
Or use compose (uses published image):
```
docker compose up -d
```
Visit: http://localhost:9123

### Data Sources
* KVV Departures: Public endpoint (JSON) for stop IDs 7000044 / 7000045.
* Weather: Open‑Meteo forecast API (lat 49.0094, lon 8.4044, Europe/Berlin TZ).
* Flatastic: Auth via `x-api-key` (user provided).
* Home Assistant: Long‑lived bearer token (refactor recommended).

### Adding a New Card
1. Create a directory under `src/components/<NewCard>/` with `NewCard.tsx` & optional `style.module.css`.
2. Wrap content with existing `Card` component (`icon` + `name` props).
3. Register inside `Dashboard.tsx` where layout lives (using `CardColumn` / `CardRow`).

### State Management Notes
All data fetching is encapsulated inside zustand store `fetch` methods invoked on an interval within the respective components. Consider centralizing polling or using React Query if complexity grows.
