This package is distributed as a UMD module and can also be used in AMD based systems or as a global under the

    "spatialReference": {
      "wkid": 4326


import { arcgisToGeoJSON } from '@esri/arcgis-to-geojson-utils';
import { geojsonToArcGIS } from '@esri/arcgis-to-geojson-utils';

// parse ArcGIS JSON, convert it to GeoJSON const geojson = arcgisToGeoJSON({ "x":-122.6764, "y":45.5165, "spatialReference": { "wkid": 4326 } });

// take GeoJSON and convert it to ArcGIS JSON const arcgis = geojsonToArcGIS({ "type": "Point", "coordinates": [45.5165, -122.6764] });


const esriUtils = require('@esri/arcgis-to-geojson-utils');

esriUtils.geojsonToArcGIS(/* ... /); esriUtils.arcgisToGeoJSON(/ ... */);

Thanks to @JeffJacobson, TypeScript typings and tests can be found on npm.

We recommend using

--moduleResolution Node
to ensure the compiler recognizes the types.
