react-mapboxgl-spiderifier

Rendering the spiderifier into react-mapbox-gl as React component.

Spiral/Circle positioning logic taken from and credits goes to https://github.com/jawj/OverlappingMarkerSpiderfier.

Examples:

• https://github.com/thuanmb/react-mapbox-gl-spiderifier/blob/master/src/App.js

Usage:

Simple spiderfication

Please note that the ReactMapboxGlSpiderifier should be used together with the React wrapper of mapbox-gl e.g. react-mapbox-gl. https://github.com/alex3165/react-mapbox-gl

import ReactMapboxGl from 'react-mapbox-gl';
import { ReactMapboxGlSpiderifier } from 'react-mapbox-gl-spiderifier';

const Map = ReactMapboxGl({
  accessToken: '...',
});

const mapProps = {
  style: 'mapbox://styles/mapbox/streets-v8',
};

class App extends Component {
  onStyleLoad = (map) => {
    this.map = map;
  };

  renderPopup(properties, coordinates, offset) {
    if (this.currentPopup) {
      this.currentPopup.remove();
    }

    setTimeout(() => {
      this.currentPopup = new MapboxGl.Popup({ offset })
        .setLngLat(coordinates)
        .setHTML(`Some description for node ${properties.value}`)
        .addTo(this.map);
    });
  }

  renderSpiderifierContent(key, value) {
    return (
      <div className="spiderifier-marker-content" key={key} properties={{ value }}>
        <div>{value}</div>
      </div>
    )
  }

  render() {
    return (
      <div className="App">
        <Map {...mapProps} onStyleLoad={this.onStyleLoad}>
          <ReactMapboxGlSpiderifier
            coordinates={[-0.2268, 51.5361]}
            onClick={(properties, coords, offset) => this.renderPopup(properties, coords, offset)}
           >
            {[100, 200, 300, 400, 500].((n, index) => this.renderSpiderifierContent(index, n))}
          </ReactMapboxGlSpiderifier>
        </Map>
      </div>
    );
  }
}
