node-geocoder

Node library for geocoding and reverse geocoding

Currently in development

Installation

npm install node-geocoder

Usage example

var geocoderProvider = 'google';
var httpAdapter = 'http';
// optionnal
var extra = {
    apiKey: 'YOUR_API_KEY',
    formatter: null
};

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

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

// 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'
}]

Geocoder Provider

• google : GoogleGeocoder support address geocoding and reverse geocoding
• freegeoip : FreegeoipGeocoder support ip geocoding
• datasciencetoolkit : DataScienceToolkitGeocoder supports ip v4 geocoding and address geocoding
• openstreetmap : OpenStreetMapGeocoder support address geocoding and reverse geocoding
• mapquest : MapQuestGeocoder support address geocoding and reverse geocoding need an apiKey

Http adapter

• http : This adapter uses Http nodejs library (by default)
• requestify : This adapter uses Requestify library (you need to install requestify)

Formatter

• 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

More

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

To run tests just npm test

Extending node geocoder

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

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