Google map library for react that allows rendering components as markers

by React

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.

See it in action at jsbin

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={'Kreyser Avrora'}
          />
        </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 ugly 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.

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.
