Description

If you are faced with an issue with markers overlapping during map zooming, or they are overlapping because they are close to each other - you probably need to group them.
That is what you can do with react-leaflet-markercluster.

Just grab your markers inside <MarkerClusterGroup /> component, right after <TileLayer />:

import MarkerClusterGroup from 'react-leaflet-markercluster';

<MarkerClusterGroup>
  <Marker position={[49.8397, 24.0297]} />
  <Marker position={[52.2297, 21.0122]} />
  <Marker position={[51.5074, -0.0901]} />
</MarkerClusterGroup>;

Note: Before getting started, please see these useful guides:

Table of Contents

Getting started

1. Install package:

yarn add react-leaflet-markercluster@next # yarn
npm install react-leaflet-markercluster # npm

NOTE: the @next is required for react-leaflet v3 support. If you are still using react-leaflet v3, add dependency as react-leaflet-markercluster@^2.x.x

The react-leaflet-markercluster requires leaflet.markercluster as peerDependency

(Leaflet and react-leaflet also should be installed)

yarn add leaflet.markercluster leaflet react-leaflet # yarn
npm install leaflet.markercluster leaflet react-leaflet # npm

2. Import markercluster and leaflet styles:

@import '~leaflet/dist/leaflet.css'; // sass
@import '~react-leaflet-markercluster/dist/styles.min.css'; // sass

require('~leaflet/dist/leaflet.css'); // inside .js file
require('react-leaflet-markercluster/dist/styles.min.css'); // inside .js file

Or include CSS styles directly to the head of HTML file:

<link rel="stylesheet" href="https://unpkg.com/leaflet/dist/leaflet.css" />

<link
  rel="stylesheet"
  href="https://unpkg.com/react-leaflet-markercluster/dist/styles.min.css"
/>

3. Write some simple react-leaflet Map:

import { MapContainer, TileLayer, Marker } from 'react-leaflet';

<MapContainer
  className="markercluster-map"
  center={[51.0, 19.0]}
  zoom={4}
  maxZoom={18}
>
  <TileLayer
    url="https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png"
    attribution='&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
  />

  <Marker position={[49.8397, 24.0297]} />
  <Marker position={[52.2297, 21.0122]} />
  <Marker position={[51.5074, -0.0901]} />
</MapContainer>;

NOTE: Remember to add map styles .markercluster-map { height: 90vh; }.

4. Just grab your markers inside <MarkerClusterGroup /> component, right after <TileLayer />:

import MarkerClusterGroup from 'react-leaflet-markercluster';

<MarkerClusterGroup>
  <Marker position={[49.8397, 24.0297]} />
  <Marker position={[52.2297, 21.0122]} />
  <Marker position={[51.5074, -0.0901]} />
</MarkerClusterGroup>;

API

Just pass whatever option you need from All Leaflet.markercluster Options to MarkerClusterGroup as prop.

For example:

<MarkerClusterGroup showCoverageOnHover={false} />

or:

const createClusterCustomIcon = function (cluster) {
  return L.divIcon({
    html: `<span>${cluster.getChildCount()}</span>`,
    className: 'marker-cluster-custom',
    iconSize: L.point(40, 40, true),
  });
}

<MarkerClusterGroup iconCreateFunction={createClusterCustomIcon} />

P.S: Examples for v1 are available at CHANGELOG.md

Event listeners

You are able to add any listener, supported by Leaflet, with simple on property prefix.
