Getting error while implementing Turf with Arcgis

Hi,

While implementing the Turf with the Arcgis, below error is coming:

Argument of type '{ type: string; properties: { stroke: string; }; features: { type: string; properties: { color: string; }; geometry: { type: string; coordinates: number[][]; }; }[]; }' is not assignable to parameter of type 'Position[]'.

PFB the code snippet:

const getPoint = () => {

var line = turf.lineString({

type: 'FeatureCollection',

features: [

{

type: 'Feature',

properties: {

color: 'orange'

geometry: {

type: 'Polygon',

coordinates: [

[-77.031669, 38.878605],

[-77.029609, 38.881946],

[-77.020339, 38.884084],

[-77.025661, 38.885821],

[-77.021884, 38.889563],

[-77.019824, 38.892368],

]

}

]

});

const pt = turf.point([this.lat, this.lon]);

console.log('Inside turf', this.lat);

const snapped = turf.nearestPointOnLine(line, pt, {units: 'miles'});

};

Turf isn't an Esri product. You can get support on the github page for turf https://github.com/Turfjs/turf/

Hi,

I checked this link as well. I just wanna used the properties to show the nearby points on the map for a given route. So that is why i am using TUrf.

Is there any way to do that in Arcgis using Turf.

You'll need to covert the GeoJSON result to an ArcGIS geometry.

https://developers.arcgis.com/javascript/latest/api-reference/esri-geometry-Point.html

Point takes a latitude and longitude you can use. I have no samples for this.
