[![npm version](https://badge.fury.io/js/google-map-react.svg)](http://badge.fury.io/js/google-map-react)
[![Build Status](https://travis-ci.org/istarkov/google-map-react.svg?branch=master)](https://travis-ci.org/istarkov/google-map-react)

`google-map-react` is a component written over a small set of the [Google Maps API](https://developers.google.com/maps/). 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](http://istarkov.github.io/google-map-react/map/main) *(You can scroll the table, zoom/move the map, hover/click on markers, and click on table rows)*

## 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](http://istarkov.github.io/google-map-react/map/main), you will still be able to hover on almost every map marker.

## What's it Look Like?

In the simple case you just need to add `lat` `lng` props to any child of `GoogleMapReact` component.

[See it in action at jsbin](https://jsbin.com/gaxapezowo/1/edit?js,output)

```javascript
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 (
      <GoogleMapReact
        defaultCenter={this.props.center}
        defaultZoom={this.props.zoom}
      >
        <AnyReactComponent
          lat={59.955413}
          lng={30.337844}
          text={'Kreyser Avrora'}
        />
      </GoogleMapReact>
    );
  }
}
```

### bower

We no longer intend to support Bower. Please stop using Bower. NPM works very well for front-end development, and you should use it instead. ((c)Dan Abramov)
UMD AMD and other build are available under dist folder after `npm install`

## Known Issues

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