elements

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 "@arcgis/core/form/elements/FieldElement.js";
import GroupElement from "@arcgis/core/form/elements/GroupElement.js";
import RelationshipElement from "@arcgis/core/form/elements/RelationshipElement.js";
import TextElement from "@arcgis/core/form/elements/TextElement.js";

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

import { FieldElement, GroupElement, RelationshipElement, TextElement } from "@arcgis/core/form/elements.js";

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

import { Element } from "@arcgis/core/form/elements.js";

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 | relationship`
    console.log("The value is not a valid form element.")
  }
}
