Close Cluster ​

The closeCluster function is used to close a cluster. It takes a MarkerCluster as the first argument.

Why do I need this function? ​

Leaflet.markercluster can close a cluster by clicking on it. But if you want to close a cluster programmatically, you need to use this function.

"But I can use the .unspiderfy() function of the MarkerCluster class!"

Yes, you can. This time I don't have any good reason to convince you to use this function instead of the .unspiderfy() function. I just wanted to have a function to close a cluster. If you want to use the .unspiderfy() function, go ahead.

Important Notes ​

• Check the getCurrentZoomCluster function to understand how this function works.

import { closeCluster, getClusterAtCurrentZoom } from 'leaflet-markercluster-utils';

const cluster = L.markerClusterGroup();

const marker1 = L.marker([0, 0]);
const marker2 = L.marker([0, 0]);

cluster.addLayer(marker1);
cluster.addLayer(marker2);

map.addLayer(cluster);

document.querySelector('#open-cluster').addEventListener('click', () => {
  closeCluster(getClusterAtCurrentZoom(map.getZoom(), marker1));
});
