Google Map React ·
google-map-react
is a component written over a small set of the Google Maps API. It allows you to render any React component on the Google Map. It is fully isomorphic and can render on a server. Additionally, it can render map components in the browser even if the Google Maps API is not loaded. It uses an internal, tweakable hover algorithm - every object on the map can be hovered.
It allows you to create interfaces like this example (You can scroll the table, zoom/move the map, hover/click on markers, and click on table rows)
Getting started
In the simple case you just need to add lat
and lng
props to any child of GoogleMapReact
component.
import React, { Component } from 'react';
import GoogleMapReact from 'google-map-react';
const AnyReactComponent = ({ text }) => <div>{text}</div>;
class SimpleMap extends Component {
static defaultProps = {
center: {
lat: 59.95,
lng: 30.33
},
zoom: 11
};
render() {
return (
// Important! Always set the container height explicitly
<div style={{ height: '100vh', width: '100%' }}>
<GoogleMapReact
bootstrapURLKeys={{ key: /* YOUR KEY HERE */ }}
defaultCenter={this.props.center}
defaultZoom={this.props.zoom}
>
<AnyReactComponent
lat={59.955413}
lng={30.337844}
text="My Marker"
/>
</GoogleMapReact>
</div>
);
}
}
export default SimpleMap;
My map doesn't appear!
- Make sure the container element has width and height. The map will try to fill the parent container, but if the container has no size, the map will collapse to 0 width / height. This is not a requirement for google-map-react, its a requirement for google-maps in general.
Installation
npm:
npm install --save google-map-react
yarn:
yarn add google-map-react
Features
Works with your Components
Instead of the default Google Maps markers, balloons and other map components, you can render your cool animated react components on the map.
Isomorphic Rendering
It renders on the server. (Welcome search engines) (you can disable javascript in browser dev tools, and reload any example page to see how it works)
Component Positions Calculated Independently of Google Maps API
It renders components on the map before (and even without) the Google Maps API loaded.
Google Maps API Loads on Demand
There is no need to place a <script src=
tag at top of page. The Google Maps API loads upon the first usage of the GoogleMapReact
component.
Use Google Maps API
You can access to Google Maps map
and maps
objects by using onGoogleApiLoaded
, in this case you will need to set yesIWantToUseGoogleMapApiInternals
to true
...
const handleApiLoaded = (map, maps) => {
// use map and maps objects
};
...
<GoogleMapReact
bootstrapURLKeys={{ key: /* YOUR KEY HERE */ }}
defaultCenter={this.props.center}
defaultZoom={this.props.zoom}
yesIWantToUseGoogleMapApiInternals
onGoogleApiLoaded={({ map, maps }) => handleApiLoaded(map, maps)}
>
<AnyReactComponent
lat={59.955413}
lng={30.337844}
text="My Marker"
/>
</GoogleMapReact>
PST: Remember to set yesIWantToUseGoogleMapApiInternals
to true.
Internal Hover Algorithm
Now every object on the map can be hovered (however, you can still use css hover selectors if you want). If you try zooming out here example, you will still be able to hover on almost every map marker.
Examples
Hover effects: simple hover (source); distance hover (source)
Example project: main (source); balderdash (same source as main)

Contribute
To get a reloadable env, with map, clone this project and
npm install
npm run start
# open browser at localhost:4000

Known Issues
- Older browsers (http://caniuse.com/#feat=promises) will need a ES6 Promise polyfill in order to work.
