<h2>The Drupal 8 & 9 version of Leaflet</h2>
In stable and usable version,
<ul>
  <li>embeds <a href="https://leafletjs.com/download.html" target="_blank">Leaflet Js library (version 1.4.0)</a>;</li>
  <li>provides Leaflet Map Formatter and Leaflet Map Views Integration with advanced functionalities and configurations;</li>
  <li>provides an advanced Leaflet Default Widget, with Leaflet Geoman Js library (interactive drawing of Point and Geometries) and Geocoder Autocomplete integration (with <a href="https://www.drupal.org/project/geocoder" title="Geocoder" target="_blank">Geocoder module</a>;</li>
  <li>perfectly matches with the <a href="https://www.drupal.org/project/geofield_map" title="Geofield Map module" target="_blank">Geofield Map module</a> widget;</li>
</ul>
<br>

<strong>IMPORTANT!: Since release 2.0.0 (specifically dedicated and compatibile with Drupal ^8.8 & ^9 and identical with last 8.x-1.41 release) Leaflet implements an advanced new Leaflet Default Widget</strong> (as optimisation and integration of <a href="https://www.drupal.org/project/leaflet_widget" title="Leaflet Widget" target="_blank">Leaflet Widget module</a>).

<strong>IMPORTANT!: Since 8.x-1.2 the Leaflet module itself contains the "Leaflet Markecluster" submodule</strong>, that integrates the <a href="https://github.com/Leaflet/Leaflet.markercluster" title="Leaflet Markercluster Js library" target="_blank">Leaflet Markercluster Js library (version 1.4.1)</a>.

It needs to be installed <a href="https://www.drupal.org/docs/develop/using-composer/using-composer-to-manage-drupal-site-dependencies" target="_blank">using Composer to manage Drupal site dependencies</a>, which will also download the required <a href="https://www.drupal.org/project/geofield" title="Geofield Module" target="_blank">Geofield Module</a> dependency and <a href="https://geophp.net" title="GeoPHP library">GeoPHP library</a>.
It means simply running the following command from your project root (where the main composer.json file is sited):

<b><code>$ composer require 'drupal/leaflet'</code></b>

Read the Installation and Use instructions in the Readme.md file for further details.
