# Google Map React · [![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/google-map-react/google-map-react.svg?branch=master)](https://travis-ci.org/google-map-react/google-map-react) [![PRs Welcome](https://img.shields.io/badge/PRs-welcome-brightgreen.svg)](github.com/google-map-react/google-map-react/CONTRIBUTING.md)



`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://google-map-react.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)*



## 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](https://jsbin.com/ruwogapuke/1/edit?js,output)



```javascript

import React from "react";

import GoogleMapReact from 'google-map-react';



const AnyReactComponent = ({ text }) => 
{text}
;



export default function SimpleMap(){

  const defaultProps = {

    center: {

      lat: 10.99835602,

      lng: 77.01502627

    },

    zoom: 11

  };



  return (

    // Important! Always set the container height explicitly

    


      

        

      

    


  );

}

```



### 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](https://developers.google.com/maps/documentation/javascript/tutorial).



## 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 ` {

  // 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.



[Example here](https://github.com/google-map-react/google-map-react-examples/blob/master/src/examples/Main.js#L69)



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

## Documentation



You can find the documentation here:



- [API Reference](./API.md)



- [NEW DOCS](./DOC.md) (In progress)



## Contribute



Local development is broken into two parts (ideally using two tabs).



First, run rollup to watch your `src/` module and automatically recompile it into `dist/` whenever you make changes.



```bash

npm start # runs rollup with watch flag

```



The second part will be running the `example/` create-react-app that's linked to the local version of your module.



```bash

# (in another tab)

cd example

npm start # runs create-react-app dev server

```



Now, anytime you make a change to your library in `src/` or to the example app's `example/src`, `create-react-app` will live-reload your local dev server so you can iterate on your component in real-time.



### Manual link-install

If you get the error `Module not found: Can't resolve 'google-react-map'...` while trying to run the example app, you need to manually link your local development module, try the following steps:

  1. In the root folder:

  ```bash

  npm link

  ```

  2. Go into `example/` and (after installing other dependencies) execute:

  ```bash

  npm link google-map-react

  ```

## Known Issues



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