Table of Contents


Install the package and its peer dependencies via npm:

npm install leaflet @asymmetrik/ngx-leaflet
npm install leaflet.markercluster @asymmetrik/ngx-leaflet-markercluster

If you intend to use this library in a typescript project (utilizing the typings), you will need to also install the leaflet typings via npm:

npm install @types/leaflet @types/leaflet.markercluster


This plugin is used with the Angular.io Leaflet plugin.

The first step is to follow the instructions to get @asymmetrik/ngx-leaflet working. Next, follow a similar process to install and configure this plugin. Generally, the steps are:

  • Install this package and its dependencies (see above).
  • Import the leaflet.markercluster stylesheet (i.e., node_modules/leaflet.markercluster/dist/MarkerCluster.Default.css). Follow the same process as documented in @asymmetrik/ngx-leaflet.
  • Import the LeafletMarkerClusterModule into your Angular application module and local module (if applicable).
  • Create and configure a map (see docs below and/or demo)

To create a map, use the leaflet attribute directive. This directive must appear first. You must specify an initial zoom/center and set of layers either via leafletOptions or by binding to leafletZoom, leafletCenter, and leafletLayers.

<div style="height: 400px;"

Finally, to initialize and configure the leaflet markercluster plugin, use the following attribute directives:


This attribute is an attribute directive that initiates the marker cluster plugin and binds the marker data.


Input binding for the options to be passed directly to the marker cluster plugin upon creation. These options are only currently processed at creation time.

The options object is passed through to the leaflet.markercluster object. Therefore, you can reference their documentation for help configuring this plugin.

Getting a reference to the MarkerCluster Layer

There is an optional output event emitter that will expose the markercluster group being used by the plugin called leafletMarkerClusterReady. See the following example:

<div style="height: 400px;"
markerClusterReady(markerCluster: L.MarkerClusterGroup) {
    // Do stuff with group
