react-leaflet-cluster-4-next github-repo

This is a fork of react-leaflet-cluster, originally created by akursat.
It includes slight modifications to fix issues related to CSS imports in Next.js.

Key Changes

• Disabled CSS imports from index.js.
• Required: Add MarkerCluster.css and MarkerCluster.Default.css manually to your global CSS.

Compatibility

• Tested with React 18 and Next.js 14.2.
• Use with @react-leaflet/[email protected].

Installation

npm install react-leaflet-cluster-4-next

example

import MarkerClusterGroup from 'react-leaflet-cluster-4-next';
...

<MapContainer
      ref={mapRef}
      zoomControl={false}
      center={defaltLoc}
      className="w-screen h-screen z-0"
    >
...
      <MarkerClusterGroup
        chunkedLoading
      >
        {markers?.map((marker, index) => (
          <CustomMarker key={index} marker={marker} index={index} />
        ))}
      </MarkerClusterGroup>
    </MapContainer >
