Esri Leaflet

Leaflet plugins for ArcGIS Services. Currently Esri Leaflet supports loading Esri basemaps and feature services, as well as tiled map, dynamic map and image services.

The goal of Esri Leaflet is not to replace the ArcGIS API for JavaScript, but rather to provide small components to allow developers to build mapping applications with Leaflet.

Demos

We've written loads of demos showing many of the features of Esri Leaflet.

Example

Here is a quick example to get you started. Just copy/paste into your own .html file and run.

<!DOCTYPE html>
<html>
  <head>
     <!-- Load Leaflet from CDN-->
    <link rel="stylesheet" href="http://cdn.leafletjs.com/leaflet-0.7.3/leaflet.css" />
    <script src="http://cdn.leafletjs.com/leaflet-0.7.3/leaflet.js"></script>

    <!-- Load Esri Leaflet from CDN -->
    <script src="http://cdn.jsdelivr.net/leaflet.esri/1.0.0/esri-leaflet.js"></script>

    <style>
      html, body,  #map {
        width : 100%;
        height : 100%;
      }
    </style>
  </head>
  <body>
    <div id="map"></div>
    <script>
      var map = L.map('map').setView([45.528, -122.680], 13);

      L.esri.basemapLayer("Gray").addTo(map);

      var parks = L.esri.featureLayer({
        url: "http://services.arcgis.com/rOo16HdIMeOBI4Mb/arcgis/rest/services/Portland_Parks/FeatureServer/0",
        style: function () {
          return { color: "#70ca49", weight: 2 };
        }
      }).addTo(map);

      var popupTemplate = "<h3>{NAME}</h3>{ACRES} Acres<br><small>Property ID: {PROPERTYID}<small>";

      parks.bindPopup(function(feature){
        return L.Util.template(popupTemplate, feature.properties)
      });
    </script>
  </body>
</html>
