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.
Currently Esri Leaflet is in development and should be thought of as a beta or preview.
Demos
There are loads of demos showing many of the features of Esri Leaflet.

Versioning
For transparency into the release cycle and in striving to maintain backward compatibility, Esri Leaflet is maintained under the Semantic Versioning guidelines and will adhere to these rules whenever possible.
Releases will be numbered with the following format:
<major>.<minor>.<patch>
And constructed with the following guidelines:
- Breaking backward compatibility bumps the major while resetting minor and patch
- New additions without breaking backward compatibility bumps the minor while resetting the patch
- Bug fixes and misc changes bumps only the patch
