Interactive map visualization of all US zip code boundaries using vector tiles for fast, efficient rendering.

• 33,791 zip codes across the United States
• PMTiles vector tiles for optimal performance
• Color-coded regions with 10-color palette
• Smooth panning and zooming
• City/town labels remain visible above zip boundaries

# Install dependencies
bun install

# Run development server
bun dev

Open http://localhost:3001 to view the map.

The zip code boundaries are sourced from TIGER/Line Shapefiles provided by the US Census Bureau. The GeoJSON data is converted to PMTiles vector tiles for efficient web delivery.

To regenerate tiles from source data:

cd apps/web

# Apply hash-based coloring to GeoJSON
bun run color-us-zips

# Convert to PMTiles (requires tippecanoe)
bun run generate-tiles
