Node library for geocoding and reverse geocoding. Can be use as a nodejs library or as a command line

npm install -g node-geocoder
geocoder --provider google 'Fornino, 187 Bedford Ave, Brooklyn, NY 11211'

npm install node-geocoder

var geocoderProvider = 'google';
var httpAdapter = 'http';
// optionnal
var extra = {
    apiKey: 'YOUR_API_KEY', // for map quest
    formatter: null         // 'gpx', 'string', ...
};

var geocoder = require('node-geocoder').getGeocoder(geocoderProvider, httpAdapter, extra);

// Using callback
geocoder.geocode('29 champs elysée paris', function(err, res) {
    console.log(res);
});

// Or using Promise
geocoder.geocode('29 champs elysée paris')
    .then(function(res) {
        console.log(res);
    })
    .catch(function(err) {
        console.log(err);
    });

// output :
[{
    latitude: 48.8698679,
    longitude: 2.3072976,
    country: 'France',
    countryCode: 'FR',
    city: 'Paris',
    zipcode: '75008',
    streetName: 'Champs-Élysées',
    streetNumber: '29',
    state: 'Île de France',
    stateCode: 'IDF'
}]

## Advenced usage (only google provider)
geocoder.geocode({address: '29 champs elysée', country: 'France', zipcode: '75008', function(err, res) {
    console.log(res);
});

// Reverse example

// Using callback
geocoder.reverse(45.767, 4.833, function(err, res) {
    console.log(res);
});

// Or using Promise
geocoder.reverse(45.767, 4.833)
    .then(function(res) {
        console.log(res);
    })
    .catch(function(err) {
        console.log(err);
    });

• google : GoogleGeocoder support address geocoding and reverse geocoding, use extra.clientIdand extra.apiKey(privateKey)for business licence, you can also use extra.language for specify language. Note that 'https' is required when using an apiKey
• freegeoip : FreegeoipGeocoder support ip geocoding
• datasciencetoolkit : DataScienceToolkitGeocoder supports ip v4 geocoding and address geocoding, use extra.host for specify a local instance
• openstreetmap : OpenStreetMapGeocoder support address geocoding and reverse geocoding
• mapquest : MapQuestGeocoder support address geocoding and reverse geocoding need an apiKey
• openmapquest : Open MapQuestGeocoder (based on OpenStreetMapGeocoder) support address geocoding and reverse geocoding need an apiKey
• agol : ArcGis Online Geocoding service, supports geocoding and reverse. Requires a client_id & client_secret
• tomtom: TomTomGeocoder support address geocoding , you need to specify extra.apiKey

• http: This adapter uses Http nodejs library (by default)
• https: This adapter uses Https nodejs library

• gpx : format result using GPX format
• string : format result to an String array (you need to specify extra.formatterPattern key)
  • %P country
  • %p country code
  • %n street number
  • %S street name
  • %z zip code
  • %T State
  • %t state code

You can improve this project by adding new geocoders or http adapters.

To run tests just npm test

To check code style install jshint and just run `jshint lib test

You can add new geocoders by implementing the two method geocode & reverse:

var geocoder = {
    geocode: function(value, callback) { },
    reverse: function(lat, lng, callback) { }
}

You can also add formatter implementing this interface

var formatter = {
    format: function(data) { return formattedData; },
}
