geometry

A convenience module for importing Geometry classes when developing with TypeScript. For example, rather than importing geometries one at a time like this:

import Point from "@arcgis/core/geometry/Point.js";
import Polygon from "@arcgis/core/geometry/Polygon.js";
import Polyline from "@arcgis/core/geometry/Polyline.js";

You can use this module to import them on a single line:

import { Point, Polygon, Polyline } from "@arcgis/core/geometry.js";

This module also allows you to implement type guards on geometries, making your code smarter.

import { GeometryUnion } from "@arcgis/core/unionTypes.js";

function logGeometry(geometry: Geometry): void {
  if (geometry.type === "point") {
    // new at 4.6, the compiler knows the geometry is a Point instance
    console.log("point coords: ", geometry.x, geometry.y, geometry.z);
  }
  else {
    // the compiler knows the geometry must be a `Extent | Polygon | Multipoint | Polyline`
    console.log("The value is a geometry, but isn't a point.")
  }
}
