CodeSandbox Getting Started

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 component, right after :

``javascript
import MarkerClusterGroup from 'react-leaflet-markercluster';





;
`

Getting started

1. Install package:

`bash
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)

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

2. Import markercluster and leaflet styles:

`javascript
@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:

`html


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

3. Write some simple react-leaflet Map:

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

className="markercluster-map"
center={[51.0, 19.0]}
zoom={4}
maxZoom={18}
>
url="https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png"
attribution='© OpenStreetMap contributors'
/>




;
`

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

4. Just grab your markers inside component, right after :

`javascript
import MarkerClusterGroup from 'react-leaflet-markercluster';





;
`

API

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

For example:

`javascript

`

or:

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


`

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

$3

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

How to run DEV env

1. Clone the repo:

`bash
git clone https://github.com/YUzhva/react-leaflet-markercluster.git
`

2. Install all dependencies:

`bash
yarn install --no-lockfile # yarn
npm install # npm
`

3. Start the server:

`bash
yarn dev # yarn
npm run dev # npm
`

4. After starting the server, storybook should automatically open the following address:

`
http://localhost:8080/
`
