Types

Main export

import type {
  ClusteredMapViewProps,
  RenderClusterProps,
} from 'react-native-better-clustering'

ClusteredMapViewProps extends react-native-maps MapViewProps with clustering options (radius, minPoints, onClusterPress, renderCluster, etc.).

RenderClusterProps is passed to renderCluster — a ClusterFeature plus onPress, clusterColor, clusterTextColor, and tracksViewChanges.

GeoJSON types (/geojson)

import type {
  PointFeature,
  ClusterFeature,
  PointOrClusterFeature,
  BBox,
} from 'react-native-better-clustering/geojson'

Cluster properties include cluster, cluster_id, point_count, point_count_abbreviated, and getExpansionRegion().

Engine types (/engine)

import type {
  SuperclusterOptions,
  ClusterPropertyConfig,
  MapDimensions,
} from 'react-native-better-clustering/engine'

SuperclusterOptions

Option	Default	Description
radius	40	Cluster radius in pixels
minZoom	1	Min zoom for clustering
maxZoom	20	Max zoom for clustering
minPoints	2	Min points to form a cluster
extent	512	Tile extent
nodeSize	64	KD-tree leaf size
clusterProperties	[]	Map/reduce aggregation configs

Headless engine (ClusterEngine)

Low-level Nitro hybrid object — create via createClusterEngine() from /engine. See the headless engine guide for lifecycle, isBuilt checks, and error behavior.

import {
  createClusterEngine,
  type ClusterEngine,
  type ClusterEngineOptions,
  type EngineClusterNode,
  type Viewport,
} from 'react-native-better-clustering/engine'

Lifecycle: setOptions → setPoints (packPoints() buffer) → build() → query. Query methods throw when isBuilt is false; setPoints throws on invalid buffers.
