nearest-point-on-geometry

Takes a point and a geometry (Point, Polygon, LineString, GeometryCollection, ...) and calculates the closest point on the geometry using turf. If the point lies within a polygon, it will return the point itself.

nearest-point-on-geometry mostly relies on @turf/nearest-point-on-line and accepts the same parameters.

Usage

``js
const nearestPointOnGeometry = require('nearest-point-on-geometry')

let line = turf.lineString([
[-77.031669, 38.878605],
[-77.029609, 38.881946],
[-77.020339, 38.884084],
[-77.025661, 38.885821],
[-77.021884, 38.889563],
[-77.019824, 38.892368]
])
let pt = turf.point([-77.037076, 38.884017]);

let snapped = nearestPointOnGeometry(line, pt, {units: 'miles'})

console.log(snapped)
