# XPro Map Visualizer

Tiny static WMS viewer for the GeoServer endpoint at `https://xpro-viz.jfig.net/geoserver/xpro/wms`.

## Run locally

Start the included Node server:

```bash
npm install
npm start
```

Then open `http://localhost:4173`.

## Run with Docker

Using Docker Compose:

```bash
cp .env.example .env
# Edit .env and set GEOSERVER_PASSWORD.
docker compose up --build
```

Then open `http://localhost:4173`.

Build the image:

```bash
docker build -t xprov-map-visualizer .
```

Run the container:

```bash
docker run --rm -p 4173:4173 xprov-map-visualizer
```

Then open `http://localhost:4173`.

The browser never receives the GeoServer password. Configure it in `.env` for
the backend proxy:

```bash
GEOSERVER_USERNAME=admin
GEOSERVER_PASSWORD=change-me
```

To change the default WMS endpoint or allow additional WMS endpoints through
the proxy, edit `.env`:

```bash
WMS_ENDPOINT=https://xpro-viz.jfig.net/geoserver/xpro/wms
ALLOWED_WMS_ENDPOINTS=https://xpro-viz.jfig.net/geoserver/xpro/wms,https://example.com/geoserver/wms
```

## Notes

- The app does not store the password in the repo, local storage, or the browser.
- The included server proxies WMS requests so the browser does not run into cross-origin auth issues.
- The proxy only allows configured WMS endpoints. By default it allows the XPro GeoServer endpoint.
- It fetches WMS capabilities with backend HTTP Basic Auth and loads all discovered layers on top of OpenStreetMap.
- The currently published layers discovered during setup were `parcelas` and `predios`.
