Who am I?

• Joined ESRI in 2012
• Came from a web design/startup background
• ArcGIS was something people asked me how to print from in college
• I didn't know what spatial references, projects, mercator or renderers were

Leaflet?

• Open Source Mapping API
• Used by OSM, Mapbox, Data.gov
• Small, Extensible API

Brief History of Esri Leaflet

• I loved the simplicity of Leaflet to consuming ArcGIS Online services
• Started very simple, Feature Services, Basemaps, Dynamic Map Services
• Grown in capabilities, contributors and stability.
• Most popular Esri Open Source project.

Smackdown!

Esri Leaflet vs JS API

Who Wins?

No One

Good developers choose the right tools for the project

Esri Leaflet

• Supports a wide variety of ArcGIS Services
• Clean Simple API
• Growing Fast
• Open Source

Esri Leaflet

• Doesn't support non-mercator tiles
• No Renderer support
• No Webmap support

JS API

• Offically maintained and supported by a large team
• Supports ALL the functionality of ArcGIS
• Comes with lots of UI components
• Lots of helper components from Dojo
• Very opinionated

Choose Esri Leaflet if you...

• are integrating into existing apps
• are already using Leaflet
• want a simpler focused toolset
• want to leverage non-ArcGIS Services or data
• want to leverage Leaflet Plugins
• easier integration w/ frameworks and build systems

Choose the JS API if you...

• need deep integration with ArcGIS
• want to support everything (renderers, web maps…)
• work in non-web-mercator/wgs 84 projections
• love Dojo
