HeatmapLayer

HeatmapLayer component for react-leaflet v4

A custom implementation using leaflet.heat that integrates with react-leaflet v4. Supports all standard heatmap configurations including custom gradients, radius, and intensity. Works with both geographic maps and static images (floor plans).

Installation

import { HeatmapLayer } from 'uxp/components';

Signature

const HeatmapLayer: React.FunctionComponent<IHeatmapLayerProps>

Examples

tsx
// Regular map heatmap
<HeatmapLayer
  points={[
    { latitude: 1.29, longitude: 103.85, intensity: 0.8 },
    { latitude: 1.30, longitude: 103.86, intensity: 1.0 }
  ]}
  radius={40}
  blur={20}
  max={1.0}
  gradient={{
    0.0: 'blue',
    0.5: 'lime',
    0.7: 'yellow',
    1.0: 'red'
  }}
/>

// Static image heatmap
<HeatmapLayer
  points={imageHeatmapPoints}
  coordinateConverter={(lat, lng) => convertFromImagePosition(lng, lat, imageWidth, imageHeight)}
  radius={50}
  gradient={{ 0.0: 'navy', 0.5: 'cyan', 1.0: 'red' }}
/>
