Esri Leaflet
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 :heart: 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 Maps SDK 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.
