Map is not loaded correctly

[hoangviet1112]

Please provide an explanation of the issue

I have this component but the map is not loaded correctly, can someone help to figure out what is happened?

import { useCallback, useMemo, useRef } from 'react';
import {
  GoogleMap,
  Marker,
  MarkerClusterer,
  useJsApiLoader,
} from '@react-google-maps/api';

export function NewMapBox() {
  const locations = [
    { lat: -31.56391, lng: 147.154312 },
    { lat: -33.718234, lng: 150.363181 },
    { lat: -33.727111, lng: 150.371124 },

  ];

  const center = useMemo<google.maps.LatLngLiteral>(
    () => ({ lat: 53.5, lng: -5 }),
    [],
  );

  const mapRef = useRef<google.maps.Map>();
  const onLoad = useCallback((map: any) => (mapRef.current = map), []);
  const { isLoaded } = useJsApiLoader({
    googleMapsApiKey: config.GOOGLE_MAPS_API_KEY,
    id: 'google-map-script',
  });

  return (

                return (

                        noClustererRedraw={true}
                        position={{

          )}
        </GoogleMap>
      )}
    </div>
  );
}

Your Environment

How does it behave?

How should it behave correctly?

Basic implementation of incorrect behavior in codesandbox.com

Here is the result of this component

@hoangviet1112 please look at your browser logs for errors. Also please do not post unformatted code. Provide a link to minimal reproduction in codesandbox.io for example

@hoangviet1112 first make your file js-> jsx because you are working html also

`import { useCallback, useState } from "react"; import { GoogleMap, Marker, MarkerClusterer, useJsApiLoader, } from "@react-google-maps/api";

const locations = [ { lat: -31.56391, lng: 147.154312 }, { lat: -33.718234, lng: 150.363181 }, { lat: -33.727111, lng: 150.371124 }, { lat: -33.848588, lng: 151.209834 }, { lat: -33.851702, lng: 151.216968 }, { lat: -34.671264, lng: 150.863657 }, { lat: -35.304724, lng: 148.662905 }, { lat: -36.817685, lng: 175.699196 }, { lat: -36.828611, lng: 175.790222 }, { lat: -37.75, lng: 145.116667 }, { lat: -37.759859, lng: 145.128708 }, { lat: -37.765015, lng: 145.133858 }, { lat: -37.770104, lng: 145.143299 }, { lat: -37.7737, lng: 145.145187 }, { lat: -37.774785, lng: 145.137978 }, { lat: -37.819616, lng: 144.968119 }, { lat: -38.330766, lng: 144.695692 }, { lat: -39.927193, lng: 175.053218 }, { lat: -41.330162, lng: 174.865694 }, { lat: -42.734358, lng: 147.439506 }, { lat: -42.734358, lng: 147.501315 }, { lat: -42.735258, lng: 147.438 }, { lat: -43.999792, lng: 170.463352 }, ];

const center = { lat: -3.745, lng: -38.523, };

const containerStyle = { width: "400px", height: "300px", };

export function NewMapBox() { const apiKey = "apikey"; const { isLoaded } = useJsApiLoader({ googleMapsApiKey: apiKey, id: "google-map-script", });

const [map, setMap] = useState(null); const onLoad = useCallback((map) => { const bounds = new window.google.maps.LatLngBounds(center); map.fitBounds(bounds); }, []);

return (

); }`

The code is typescript, but you are trying to run it as javascript. Either remove types from the code and rename it to jsx, or rename file to tsx and setup typescript for your project.
