Is there a solution like leaflet-knn in ArcGIS (js-api) for finding the nearest point in a geoJSON multi-point feature to a given point? - leaflet

Question

This is how i get the closest point on a geoJSON line to a given point using leaflet-knn:
Given a point, find the nearest points to it. If the index contains multi-point features, like lines, polygons, and so on, it returns points in those features and can return more than one point in each feature.
const line= L.geoJSON(this.lineFromGeoJson, {
onEachFeature: (feature, layer) => {
layer.bindPopup(
'insignificant feature stuff here',
{maxHeight: this.screenHeight, maxWidth: this.screenWidth, autoPan: true});
}
}).addTo(this.map);
const nearest = leafletKnn(line).nearest(L.latLng(this.lat, this.longt), 1);
Is there anything similar in #arcgis/core?
I'm already using the geodesicUtils.geodesicLengths from arcgis to get the length of this geoJSON line and i figured perhaps there was a solution for this in arcgis that i have not found?

Answer 1

I think you could use geometryEngine.nearestVertices method (ArcGIS JS API - esriGeometry).
Now, this method actually takes a geometry as parameter instead of a layer, so you will probably will need to "create" the geometry using the layer or better a subset of the layer.
You can get a subset of the layer (set of features) with a distance query on the layer using ArcGIS JS API - Query.
