Leaflet plugins for consuming ArcGIS Online and ArcGIS Server services.
Esri Leaflet is maintained with ❤️ by folks spanning multiple teams within Esri, but we provide no guarantee of individual features, nor a traditional product lifecycle to support planning.
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.
We've shared lots of sample code showing off many of the features of Esri Leaflet.
The easiest way to get started is to load Esri Leaflet via CDN. Here is an example you can copy/paste into your own

Many folks have written plugins to customize and extend Leaflet.
You can also pick and choose additional Esri Leaflet plugins.
If something isn't working the way you expected, please take a look at previously logged issues that resolve common problems first. Have you found a new bug? Want to request a new feature? We'd love to hear from you. Please let us know by submitting an issue.

Using this plugin, it couldn't be easier to follow the terms. Just select your basemap and the appropriate credits will always be displayed in Leaflet's own Attribution control as users pan/zoom automatically.
