React Native Better Clustering

react-native-better-clustering is a faster react-native-map-clustering — same MapView + <Marker> API, with a C++ supercluster engine via Nitro Modules instead of JS on the RN bridge.

Migration

- import MapView from 'react-native-map-clustering'
+ import MapView from 'react-native-better-clustering'

Why C++/Nitro?

Clustering large datasets in JavaScript causes dropped frames on every region change. This library builds the index in C++ and returns only visible features for the current viewport — without changing how you write map screens.

Advanced APIs

Need full control over rendering? Use subpath exports:

• /hooks — useClusterer when you own the MapView
• /engine — Supercluster class and geometry helpers
• /geojson — GeoJSON conversion utilities

Next steps

• Quick Start — install and render your first clustered map.
• Platform Setup — peers and prebuild.
• MapView API — props, callbacks, and customization.
• Hooks API — useClusterer for custom stacks.
