Leaflet plugins for working with a handful of the most popular ArcGIS Service types. This includes Esri basemaps and feature services, as well as tiled map, dynamic map and image services.
This project is maintained with ❤️ by folks on multiple teams at Esri, but we provide no guarantee of individual features, nor a traditional product lifecycle to support planning.
The goal of this project is not to replace the ArcGIS API for JavaScript but rather to provide small components for only some aspects of the ArcGIS platform for developers who prefer to build mapping applications with Leaflet.
We are proud to facilitate a project which requires participation from our diverse user community in order to thrive and we welcome contributions from those just getting their feet wet in open-source.
Support for Geocoding services and Geoprocessing services, as well as service defined rendering are available as well (via additional plugins).
If you'd like to display Esri services in any Leaflet application, we ask that you adhere to our Terms of Use and attribution requirements.
We've shared lots of sample code showing off many of the features of Esri Leaflet.

<script>
var map = L.map('map').setView([45.528, -122.680], 13);
L.esri.basemapLayer("Gray").addTo(map);
var parks = L.esri.featureLayer({
url: "https://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(e){
return L.Util.template(popupTemplate, e.feature.properties)
});
</script>

If you display an ArcGIS Online service in any Leaflet application, we require that you include Esri attribution and recognize data providers. Using this plugin, it couldn't be easier to follow the terms. Just select your basemap and the appropriate credits will be displayed dynamically in Leaflet's own Attribution control as users pan/zoom.
L.esri.basemapLayer('Topographic').addTo(map);
If you need more than 1 million map transactions per month, please let us know.
