Got it. I just test, it works. As I read, so far, terraformer does NOT support feature collection, only this module does.

from arcgis-to-geojson-utils.

Can you add the function to convert arcgis FeatureSet to geojson?

as i explained in Esri/terraformer#104 (comment), support for this is already present.

arcgis-to-geojson-utils/test/index.js

Lines 1215 to 1338 in ed3c56b
