(async () => {
  async function search(
    provider: BaseProvider,
    options = { query: 'Where is my home?' },
  ) {
    return provider.search(options);
  }

  [
    await search(new OpenStreetMapProvider()),
    await search(new BingProvider({ key: 'BING_API_KEY' })),
    await search(new EsriProvider()),
    await search(new GoogleProvider({ key: 'GOOGLE_MAPS_API_KEY ' })),
  ].forEach(([{ x, y, bounds, label, raw }]) => ({ x, y, bounds, label, raw }));
})();

import L from 'leaflet';
import {
  GeoSearchControl,
  BingProvider,
} from 'leaflet-geosearch';

const provider = new BingProvider({ params: {
  key: '__YOUR_BING_KEY__'
} });

const searchControl = new GeoSearchControl({
  provider: provider,
});

const map = new L.Map('map');
map.addControl(searchControl);
