Geocoder

Installation:

npm install geocoder

Usage

You can pass a string representation of a location and a callback function to geocoder.geocode. It will accept anything that Google will accept: cities, streets, countries, etc.

Example:

var geocoder = require('geocoder');

// Geocoding
geocoder.geocode("Atlanta, GA", function ( err, data ) {
  // do something with data
});

// Reverse Geocoding
geocoder.reverseGeocode( 33.7489, -84.3789, function ( err, data ) {
  // do something with data
});

// Setting sensor to true
geocoder.reverseGeocode( 33.7489, -84.3789, function ( err, data ) {
  // do something with data
}, { sensor: true });

// Setting language to German
geocoder.reverseGeocode( 33.7489, -84.3789, function ( err, data ) {
  // do something with data
}, { language: 'de' });


// Selecting another provider to do reverse geocoding
// Currently only geonames and yahoo placefinder are supported
geocoder.selectProvider("geonames",{"username":"demo"});

// Output will be roughly in the same format as Google's
geocoder.reverseGeocode( 33.7489, -84.3789, function ( err, data ) {
  // do something with data
});

// see http://developer.yahoo.com/geo/placefinder/guide/index.html
geocoder.selectProvider("yahoo",{"appid":"xxx"});

// Output will be roughly in the same format as Google's
geocoder.reverseGeocode( 33.7489, -84.3789, function ( err, data ) {
  // do something with data
});




Results will look like standard Google JSON Output

You can pass in an optional options hash as a last argument, useful for setting sensor to true (it defaults to false) and the language (default is empty which means that google geocoder will guess it by geo ip data). For details see the Google Geocoding API Docs

Testing:

nodeunit test

Roadmap

  • Complete Test Suite
  • Better options handling
