@mapconductor/react-for-cesium

CesiumJS provider for the MapConductor React SDK. Renders a Cesium 3D globe 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, ArcGIS, or HERE.

Installation

npm install @mapconductor/react-for-cesium

@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-cesium @mapconductor/js-sdk-core @mapconductor/js-sdk-react

cesium is bundled as a dependency; the Default design works without an Ion token.

Quick start

import { createGeoPoint, createMapCameraPosition } from '@mapconductor/js-sdk-core';
import { Marker } from '@mapconductor/js-sdk-react';
import {
  CesiumDesign,
  CesiumMapView,
  useCesiumMapViewState,
} from '@mapconductor/react-for-cesium';
import '@mapconductor/react-for-cesium/style.css';

const TOKYO = createGeoPoint({ latitude: 35.6812, longitude: 139.7671 });

export function App() {
  const state = useCesiumMapViewState({
    mapDesignType: CesiumDesign.Default,
    cameraPosition: createMapCameraPosition({ position: TOKYO, zoom: 12 }),
  });

  return (
    <div style={{ width: '100%', height: '100vh' }}>
      <CesiumMapView
        state={state}
        onMapClick={point => console.log('clicked', point.latitude, point.longitude)}
        onCameraMoveEnd={camera => console.log('zoom', camera.zoom)}
      >
        <Marker position={TOKYO} />
      </CesiumMapView>
    </div>
  );
}

The camera uses Google Maps zoom semantics; the package converts zoom levels to Cesium camera altitude internally, so cross-provider camera sync works out of the box.

Map designs

CesiumDesign ships Default (built-in imagery) and None (no imagery, e.g. for your own layers). Switch at runtime by assigning state.mapDesignType = ....
