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

import FieldElement from "esri/form/elements/FieldElement";
import GroupElement from "esri/form/elements/GroupElement";

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

import { FieldElement, GroupElement } from "esri/form/elements";

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

import { Element } from "esri/form/elements";

function logFormElement(element: Element): void {
  if (element.type === "field") {
    console.log("Form element type is field");
  }
  else {
    // The compiler knows the content element must be `field | group`
    console.log("The value is not a valid form element.")
  }
}
