### Examples

* #### Basic MapMarker

  ##### React

  ```tsx
  import {
    reactExtension,
    Map,
    MapMarker,
  } from '@shopify/ui-extensions-react/checkout';

  export default reactExtension(
    'purchase.checkout.block.render',
    () => <Extension />,
  );

  function Extension() {
    return (
      <Map
        apiKey="YOUR_GOOGLE_MAPS_API_KEY"
        latitude={-28.024}
        longitude={140.887}
        zoom={4}
        accessibilityLabel="Map"
      >
        <MapMarker
          latitude={-28.024}
          longitude={140.887}
          accessibilityLabel="Map marker for Innamincka, Australia"
        />
      </Map>
    );
  }
  ```

  ##### JS

  ```js
  import {extension, Map, MapMarker} from '@shopify/ui-extensions/checkout';

  export default extension('purchase.checkout.block.render', (root) => {
    const map = root.createComponent(
      Map,
      {
        apiKey: 'YOUR_API_KEY',
        accessibilityLabel: 'Map',
        latitude: -28.024,
        longitude: 140.887,
        zoom: 4,
      },
      [
        root.createComponent(MapMarker, {
          latitude: -28.024,
          longitude: 140.887,
          accessibilityLabel: 'Map marker for Innamincka, Australia',
        }),
      ],
    );

    root.appendChild(map);
  });
  ```

## Best Practices

* If your markers are interactive, make sure that the selected marker's icon is different from the rest of the non-selected markers.

* If there are a large number of markers obscuring important features of the map, set the markers to clusterable to help increase the readability of the map.
