React Native Super Cluster

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



  • 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
  • Use onMarkerPress event on MapView instead of using onPress directly on Markers whenever possibile, in particular if you have a lot of pins and clusters. Within onMarkerPress you have access to the marker identifier through the event.nativeEvent attribute, hence you should be able to do everything you would do within an onPress function of a Marker

Name Type Required Default Note
radius Number false window width * 4,5% SuperCluster radius.
extent Number false 512 SuperCluster extent.
minZoom Number false 1 SuperCluster minZoom.
maxZoom Number false 16 SuperCluster maxZoom.
width Number false window width map's width.
height Number false window height map's height.
data Array true undefined Objects must have an attribute location representing a GeoPoint, i.e. { latitude: x, longitude: y }.
onExplode Function false undefined TODO
onImplode Function false undefined TODO
onClusterPress(clusterId, ?children) Function false Add (or completey override) behaviours to the clusterPress handler. children is passed when default behavior is preserved (see preserveClusterPressBehavior prop).
preserveClusterPressBehavior Bool false true Whether onClusterPress prop should completely override module's behavior rather than integrate it.
clusterPressMaxChildren Function false 100 Max number of cluster leaves returned as second parameter of onClusterPress.
edgePadding Object false { top: 10, left: 10, bottom: 10, right: 10 } Edge padding for react-native-maps's fitToCoordinates method, called in onClusterPress for fitting to pressed cluster children.
renderMarker Function false undefined Must return a react-native-maps' Marker component.
animateClusters Bool false true Animate imploding/exploding of clusters' markers and clusters size change. Works only on iOS.
layoutAnimationConf LayoutAnimationConfig false LayoutAnimation.Presets.spring Custom Layout animation configuration object for clusters animation during implode / explode Works only on iOS.
clusteringEnabled Bool false true Dynamically set whether to pass through clustering functions or immediately render markers as a normal mapview.
accessor String|Func true "location" Accessor for item coordinate values. Could be a string (field name of an item object with latitude and longitude values) or a function (that describes how to access to coordinate data).
