react-mapbox-gl-cluster

react-mapbox-gl-cluster

The React component for the cluster layer in the mapbox-gl.

The cluster layer has some build-in actions:

• Zoom in when clicking on a cluster.
• Show the spiderifiers when clicking on a cluster which contains the points at same location.

This layer must be rendered inside react-mapbox-gl component.

Examples:

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

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

import React, {Component} from 'react';
import ReactMapboxGl from 'react-mapbox-gl';
import {ReactMapboxGlCluster} from 'react-mapbox-gl-cluster';
import {data} from './data';

const Map = ReactMapboxGl({
  accessToken: process.env.MAPBOX_GL_TOKEN,
});

const mapProps = {
  center: [-95.7129, 37.0902],
  zoom: [3],
  style: 'mapbox://styles/mapbox/streets-v8',
};

class App extends Component {
  getEventHandlers() {
    return {
      onClick: (properties, coords, offset) =>
        console.log(`Receive event onClick at properties: ${properties}, coords: ${coords}, offset: ${offset}`),
      onMouseEnter: (properties, coords, offset) =>
        console.log(`Receive event onMouseEnter at properties: ${properties}, coords: ${coords}, offset: ${offset}`),
      onMouseLeave: (properties, coords, offset) =>
        console.log(`Receive event onMouseLeave at properties: ${properties}, coords: ${coords}, offset: ${offset}`),
      onClusterClick: (properties, coords, offset) =>
        console.log(`Receive event onClusterClick at properties: ${properties}, coords: ${coords}, offset: ${offset}`),
    };
  }

  render() {
    return (
      <div className="App">
        <Map {...mapProps} onStyleLoad={this.onStyleLoad}>
          <ReactMapboxGlCluster data={data} {...this.getEventHandlers()} />
        </Map>
      </div>
    );
  }
}
