Esri Leaflet
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.
Demos
There are loads of demos showing the features of Esri Leaflet that will help you get started.
