Package Exports

googlemaps

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (googlemaps) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Google Maps API for Node.js

A simple way to query the Google Maps API from Node.js

This was a quick hack to work with Node.js. Criticism/Suggestions/Patches/PullReq's welcome.

Installation

Installing npm (node package manager)

curl http://npmjs.org/install.sh | sh

Installing googlemaps

npm install googlemaps

Status

APIs implemented:

TODO:

Tests for everything (using vows)

Usage

var gm = require('googlemaps');
var util = require('util');

gm.reverseGeocode('41.850033,-87.6500523', function(err, data){
  util.puts(JSON.stringify(data));
});

gm.reverseGeocode(gm.checkAndConvertPoint([41.850033, -87.6500523]), function(err, data){
  util.puts(JSON.stringify(data));
});

Both examples print: {"status":"OK","results":[{"types":["postal_code"],"formatted_address":"Chicago, IL 60695, USA"...

For the Static Maps API, you can pass in all the required parameters as well as markers, styles, and paths using the formats outlined below.

markers = [
    { 'location': '300 W Main St Lock Haven, PA' },
    { 'location': '444 W Main St Lock Haven, PA',
        'color': 'red',
        'label': 'A',
        'shadow': 'false',
        'icon' : 'http://chart.apis.google.com/chart?chst=d_map_pin_icon&chld=cafe%7C996600'
    }
]

styles = [
    { 'feature': 'road', 'element': 'all', 'rules': 
        { 'hue': '0x00ff00' }
    }
]

paths = [
    { 'color': '0x0000ff', 'weight': '5', 'points': 
        [ '41.139817,-77.454439', '41.138621,-77.451596' ]
    }
]

util.puts(gm.staticMap('444 W Main St Lock Haven PA', 15, '500x400', false, false, 'roadmap', markers, styles, paths));

This example prints the URL for the Static Map image: "http://maps.googleapis.com/maps/api/staticmap?center=444%20W%20Main%20St%20Lock%20Haven%20PA&zoom=15&size=500x400&maptype=roadmap&markers=%7C300%20W%20Main%20St%20Lock%20Haven%2C%20PA&markers=%7Ccolor%3Ared%7Clabel%3AA%7Cicon%3Ahttp%3A%2F%2Fchart.apis.google.com%2Fchart%3Fchst%3Dd_map_pin_icon%26chld%3Dcafe%257C996600%7Cshadow%3Afalse%7C444%20W%20Main%20St%20Lock%20Haven%2C%20PA&style=%7Cfeature%3Aroad%7Celement%3Aall%7Chue%3A0x00ff00&path=weight%3A5%7Ccolor%3A0x0000ff%7C41.139817%2C-77.454439%7C41.138621%2C-77.451596&sensor=false"

By giving gm.staticMap an optional callback, you can retreive the static map PNG data:

util.puts(gm.staticMap('444 W Main St Lock Haven PA', 15, '500x400', function(err, data){
  require('fs').writeFileSync('test_map.png', data, 'binary');
}, false, 'roadmap', markers, styles, paths));

You will get a map like:

Some Map

All the googlemaps functions follow this scheme: function(required, callback, optional)

All callbacks are expected to follow: function(error, results) Where the error returned is an Error object.

Please refer to the code, tests and the Google Maps API docs for further usage information.
