![]() The Clusterer can handle 10,000 or even 50,000 markers (in chrome). unspiderfy: Unspiderfies a cluster (opposite of spiderfy).spiderfy: Spiderfies the child markers of this cluster.getAllChildMarkers: Returns the array of total markers contained within that cluster.Here is a code example of loading two subgroups of markers when clicking at buttons on the map. Its mostly when I zoom out that the performance is getting bad. getChildCount: Returns the total number of markers contained within that cluster. Can you detect some way to optimize the way I load and cluster my geojson data I need to load +10000 markers divided into subgroups but its very laggy when I am showing all markers.By default, they are ) Other clusters methods spiderLegPolylineOptions: Allows you to specify PolylineOptions to style spider legs.removeOutsideVisibleBounds: Clusters and markers too far from the viewport are removed from the map for performance.( Note: the spiderfy occurs at the current zoom level if all items within the cluster are still clustered at the maximum zoom level or at zoom specified by disableClusteringAtZoom option) spiderfyOnMaxZoom: When you click a cluster at the bottom zoom level we spiderfy it so you can see all of its markers.zoomToBoundsOnClick: When you click a cluster we zoom to its bounds.showCoverageOnHover: When you mouse over a cluster it shows the bounds of its markers.addLayer ( markers ) Options Defaultsīy default the Clusterer enables some nice defaults for you: Or check out the custom example for how to customise the behaviour and appearance of the clusterer UsageĬreate a new MarkerClusterGroup, add your markers to it, then add it to the map The realworld example is a good place to start, it uses all of the defaults of the clusterer. To check the code for errors and build Leaflet from source, run jake.Install jake npm install -g jake then run npm install ![]() (not needed if you use your own iconCreateFunction instead of the default one).In each case, use files in the dist folder: Use unpkg CDN: Install with npm: npm install leaflet.markercluster.Include the plugin CSS and JS files on your page after Leaflet files, using your method of choice: Provides Beautiful Animated Marker Clustering functionality for Leaflet, a JS library for interactive maps.įor a Leaflet 0.7 compatible version, use the leaflet-0.7 branchįor a Leaflet 0.5 compatible version, Download b128e950įor a Leaflet 0.4 compatible version, Download the 0.2 release Table of Contents ![]()
