Live map of Israel showing Pikud HaOref (Home Front Command) alerts as colored area polygons per location.

Features

• Colored Voronoi area polygons per location — adjacent same-colored areas merge into contiguous zones
• Timeline slider to scrub through the last ~1–2 hours of alert history
• Sound alerts — optional audio notifications for new alerts (muted by default, toggle via 🔇)
• Click any area to see its alert history
• About modal — click ⓘ or the title for info and disclaimer

Color	Meaning
🔴 Red	Rocket/missile fire
🟣 Purple	Drone/aircraft infiltration
🟡 Yellow	Early warning / preparedness — go near your shelter, sirens may follow
🟢 Green	Event ended (fades out after 1 minute)

Development

./web-dev        # start dev server at http://localhost:8788

Requires Node.js and npx (comes with npm). Uses Wrangler to serve web/ and run the API proxy functions locally.

The polygon data file (locations_polygons.json) is not in the repo — ./web-dev downloads it automatically from the live site if missing.

Deploy

Deployed to Cloudflare Pages (static assets + TLV proxy):

./deploy

The fallback Worker (for non-TLV users) is deployed separately:

cd worker && npx wrangler deploy

Structure

  index.html          # single-file map app (all JS/CSS inline)
  cities_geo.json     # location → [lat, lng] lookup
functions/
  api/
    alerts.js         # proxies live alerts API
    history.js        # proxies history API
    alarms-history.js # proxies extended history API

  src/index.js        # fallback proxy for non-TLV users (placement: azure:israelcentral)
  wrangler.toml       # Worker config with placement and /api2/* route

Contributing

Contributions are welcome! This is a civic project built for anyone in Israel who wants better situational awareness during alerts.

Ways to help:

• Bug reports — open an issue if something looks wrong
• Location data — if a polygon is missing or misplaced, open an issue with the location name
• Features & fixes — PRs are very welcome! Please keep each PR focused on a single feature or fix. For anything beyond a small bug fix, open an issue first so we can discuss the approach before you invest the effort
• Feature flags — beta/experimental features are gated behind f- URL params (e.g. ?f-log). To add a new flag, check FF.<name> in JS or use the f-gated CSS class for visibility toggling. See CLAUDE.md for details.

To run locally, see the Development section above.
