I am using the google-map-react
NPM package to create a Google Map and several markers.
Question: How can we add the default Google Maps markers to the map?
From this Github issue, it seems that we need to access the internal Google Maps API using the onGoogleApiLoaded function.
Referring to an example from the Google Maps JS API docs, we can use the following code to render the marker, but how do we define the references to map
?
var marker = new google.maps.Marker({
position: myLatLng,
map: map,
title: 'Hello World!'
});
Current Code:
renderMarkers() {
...
}
render() {
return (
<div style={{'width':800,'height':800}}>
<GoogleMap
bootstrapURLKeys={{key: settings.googleMapApiKey}}
defaultZoom={13}
defaultCenter={{
lat: this.props.user.profile.location.coordinates[1],
lng: this.props.user.profile.location.coordinates[0]
}}
onGoogleApiLoaded={({map, maps}) => this.renderMarkers()}

</GoogleMap>
</div>
);
}

Edit:
Since this answer was posted the docs (and likely, the API) of the
GoogleMapReact
element was changed to support children. Any child withlat
andlng
would be rendered at the corresponding location on the map, as also indicated by @Jobsamuel's answer.The
onGoogleApiLoaded
callback should not be used for this purpose, as it is inferior to the declarative style and would not be re-run if changes are made to the map.Original answer (outdated):
This may not be entirely clear from the description in the Readme, but the
maps
argument is, in fact, the maps API object (andmap
is, of course, the current Google Map instance). Therefore, you should pass both to your method:and use them:
