Use Map Components (React 19 + Web Components)

This sample demonstrates wrapper-free integration of Calcite Components and ArcGIS JavaScript for Maps SDK Map components inside ArcGIS Experience Builder 1.19 (React 19 baseline). It shows how to obtain an active MapView via JimuMapViewComponent and attach it to an []<arcgis-legend>](https://developers.arcgis.com/javascript/latest/references/map-components/arcgis-legend/) component.

Contents

• manifest.json - Defines widget metadata and EXB version.
• src/runtime/widget.tsx - Functional runtime component that imports Calcite Components and Map components.
• src/setting/setting.tsx - Builder settings panel. Allows users to select a target map widget.

Prerequisites

• ArcGIS Experience Builder Developer Edition version 1.19.0.
• A map widget must be present in the experience for this sample to bind to its view.

Installation

1. Clone the SDK resources repository (or download zip).
2. Copy the folder widgets/web-component-widgets/use-web-components-19 into your EXB install at client/your-extensions/widgets/
3. Restart (or rebuild) the EXB dev environment if required.
4. Add the widget to an experience and select a map widget in its settings panel.

How It Works

import 'calcite-components'
import 'arcgis-map-components'

register custom elements before React renders. The component then:

1. Uses JimuMapViewComponent with onActiveViewChange to receive a JimuMapView.
2. Stores a ref to <arcgis-legend> via useRef.
3. Assigns the underlying MapView (activeView.view) to legendRef.current.view once available.
4. Renders a <calcite-button> (demonstrating direct Calcite usage) and the <arcgis-legend> element.
