// parse ArcGIS JSON, convert it to GeoJSON
const geojson = arcgisToGeoJSON({
    "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.
