@mapconductor/react-for-arcgis

ArcGIS Maps SDK for JavaScript provider for the MapConductor React SDK. Renders an ArcGIS MapView (2D) or SceneView (3D) through MapConductor's provider-independent camera, marker, and overlay API, so the same application code can also run on Google Maps, MapLibre, Mapbox, Leaflet, OpenLayers, Cesium, or HERE.

Installation

npm install @mapconductor/react-for-arcgis

@mapconductor/js-sdk-core and @mapconductor/js-sdk-react (used for markers and other shared components) are installed automatically as dependencies. Your code imports from both directly, so with pnpm's strict (isolated) node_modules — or whenever you prefer to declare everything you import — install them explicitly instead:

npm install @mapconductor/react-for-arcgis @mapconductor/js-sdk-core @mapconductor/js-sdk-react

@arcgis/core is bundled as a dependency. Esri basemaps require an API key from the ArcGIS Location Platform; the OSM-based designs work without one.

Pass the key to useArcGISViewState:

// Your own key. Read it from your environment however your build tool does
// it, and keep it out of source control.
const ARCGIS_API_KEY = '…';

const mapViewState = useArcGISViewState({
  apiKey: ARCGIS_API_KEY,
  mapDesignType: ArcGISDesign.Streets,
  cameraPosition: INITIAL_CAMERA,
});

Leave apiKey out and only the OSM-based designs will draw; the Esri ones report ArcGIS API key is required.

Hello Map tutorial

The simplest possible map app, built with MapConductor + ArcGIS: click the marker and a "Hello, MapConductor" bubble pops up. You can build it in the 5 steps below. It uses the OSM Standard basemap, which needs no API key, so you can copy-paste and it just works.

Step 1: Create a React project

Create a React + TypeScript project with Vite.

npm create vite@latest hello-map -- --template react-ts
cd hello-map
npm install
npm run dev

Step 2: Install MapConductor (ArcGIS)

Install the package needed to show a map. We use ArcGIS here, but you can use other map modules too.

npm install @mapconductor/react-for-arcgis

• @mapconductor/react-for-arcgis — components / hooks for ArcGIS
• @mapconductor/js-sdk-react / @mapconductor/js-sdk-core are installed automatically as dependencies.

Step 3: Show the map

Create the map state with useArcGISViewState and render it with <ArcGISMapView2D>. Give the outer element a height to make it full-screen.

import {
  ArcGISDesign,
  ArcGISMapView2D,
  useArcGISViewState,
} from '@mapconductor/react-for-arcgis';
import { createGeoPoint, createMapCameraPosition } from '@mapconductor/js-sdk-core';

const TOKYO = createGeoPoint({ latitude: 35.6812, longitude: 139.7671 });
const INITIAL_CAMERA = createMapCameraPosition({ position: TOKYO, zoom: 14 });

export default function App() {
  const mapViewState = useArcGISViewState({
    mapDesignType: ArcGISDesign.OsmStandard,
    cameraPosition: INITIAL_CAMERA,
  });

  return (
    <div style={{ width: '100vw', height: '100vh' }}>
      <ArcGISMapView2D state={mapViewState} />
    </div>
  );
}

Use ArcGISMapView instead of ArcGISMapView2D to render a 3D SceneView with the same camera semantics.

Step 4: Place a marker

Create the marker state with createMarkerState and register it with <Marker>. Write overlays as child elements of the map component.

import { useMemo } from 'react';
import { createMarkerState } from '@mapconductor/js-sdk-core';
import { Marker } from '@mapconductor/js-sdk-react';

// ...inside App...
const marker = useMemo(
  () => createMarkerState({ id: 'hello', position: TOKYO }),
  [],
);

// ...inside return...
<ArcGISMapView2D state={mapViewState}>
  <Marker state={marker} />
</ArcGISMapView2D>

Step 5: Show an InfoBubble on click

Track the selected state with useState, set it to true in the marker's onClick, and render <InfoBubble> only while selected. This is the finished app.

import { useMemo, useState } from 'react';
import {
  ArcGISDesign,
  ArcGISMapView2D,
  useArcGISViewState,
} from '@mapconductor/react-for-arcgis';
import {
  createGeoPoint,
  createMapCameraPosition,
  createMarkerState,
} from '@mapconductor/js-sdk-core';
import { InfoBubble, Marker } from '@mapconductor/js-sdk-react';

const TOKYO = createGeoPoint({ latitude: 35.6812, longitude: 139.7671 });
const INITIAL_CAMERA = createMapCameraPosition({ position: TOKYO, zoom: 14 });

export default function App() {
  const mapViewState = useArcGISViewState({
    mapDesignType: ArcGISDesign.OsmStandard,
    cameraPosition: INITIAL_CAMERA,
  });

  const [selected, setSelected] = useState(false);

  const marker = useMemo(
    () => createMarkerState({
      id: 'hello',
      position: TOKYO,
      onClick: () => setSelected(true),
    }),
    [],
  );

  return (
    <div style={{ width: '100vw', height: '100vh' }}>
      <ArcGISMapView2D state={mapViewState} onMapClick={() => setSelected(false)}>
        <Marker state={marker} />
        {selected && (
          <InfoBubble marker={marker}>
            <div style={{ padding: '8px 12px', fontWeight: 600 }}>
              Hello, MapConductor
            </div>
          </InfoBubble>
        )}
      </ArcGISMapView2D>
    </div>
  );
}

Key points

• Coordinates, cameras and markers are created with js-sdk-core functions (provider-independent).
• The map component and hooks come from react-for-arcgis (provider-specific).
• Write overlays as child elements of the map component.
• Control show / hide with React useState.
