This module wraps AirBnB's react-native-maps and uses MapBox's SuperCluster as clustering engine.

See the showcase application.

This module wants to provide a stable and performing solution for maps clustering in React Native. In particular, our efforts are focused on integrating SuperCluster methods into React's state/lifecycle events, ensuring stability, compatibility and great performance.

npm i --save react-native-maps-super-cluster

NOTES:

• the prop key of the markers rendered through renderMarker should not be left up to React. Instead, we strongly suggest to use an id in order the have unique keys while still taking advantage of React's recycling
• ClusteredMapView supports usual React children. Those children won't be affected by clustering, i.e. the behavior for those children is exactly the same as wrapping them around an AirBnB's react-native-maps instance

import React, { Component } from 'react'
import { Marker } from 'react-native-maps'
import ClusteredMapView from 'react-native-maps-super-cluster'

const INIT_REGION = {
  latitude: 41.8962667,
  longitude: 11.3340056,
  latitudeDelta: 12,
  longitudeDelta: 12
}

export default class MyClusteredMapView extends Component {
  
  ...

  renderMarker = (data) => <Marker key={data.id || Math.random()} coordinate={data.location} />

  ...

  render() {
    return (
      <ClusteredMapView
        style={{flex: 1}}
        data={this.state.data}
        initialRegion={INIT_REGION}
        renderMarker={this.renderMarker}
        {/* cluster text */}
        textStyle={{ color: '#65bc46' }}
        {/* cluster container */}
        containerStyle={{backgroundColor: 'white', borderColor: '#65bc46'}} />
    )
  }
}
