Leaflet plugins for ArcGIS Services. Currently Esri Leaflet supports loading Esri basemaps and feature services, as well as tiled, dynamic and image map 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.
Currently Esri Leaflet is in development and should be thought of as a beta or preview.
There are loads of demos showing many of the features of Esri Leaflet.
Here is a quick example to get you started. Just copy/paste into your own .html file and run.

parks.bindPopup(function(feature){
return L.Util.template(popupTemplate, feature.properties)
});
