Node Geocoder, node geocoding library, supports google maps, mapquest, open street map, tom tom, promise


Node library for geocoding and reverse geocoding. Can be used as a nodejs library

npm install node-geocoder
var geocoderProvider = 'google';
var httpAdapter = 'http';
// optional 
var extra = {
    apiKey: 'YOUR_API_KEY', // for Mapquest, OpenCage, Google Premier 
    formatter: null         // 'gpx', 'string', ... 
var geocoder = require('node-geocoder')(geocoderProvider, httpAdapter, extra);
// Using callback 
geocoder.geocode('29 champs elysée paris', function(errres) {
// Or using Promise 
geocoder.geocode('29 champs elysée paris')
    .then(function(res) {

  • google : GoogleGeocoder. Supports address geocoding and reverse geocoding. Use extra.clientIdand extra.apiKey(privateKey) for business licence. You can also use extra.language and extra.region to specify language and region, respectively. Note that 'https' is required when using an apiKey
  • here : HereGeocoder. Supports address geocoding and reverse geocoding. You must specify extra.appId and extra.appCode with your license keys. You can also use extra.language, extra.politicalView (read about political views here),, and extra.state.
  • freegeoip : FreegeoipGeocoder. Supports IP geocoding
  • datasciencetoolkit : DataScienceToolkitGeocoder. Supports IPv4 geocoding and address geocoding. Use to specify a local instance

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

You can specify request timeout using paramater extra.timeout

  • 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

node-geocoder-cli You can use node-geocoder-cli to geocode in shell

You can add new geocoders by implementing the two methods geocode and reverse:

var geocoder = {
    geocodefunction(valuecallback) { ... },
    reversefunction(querycallback) { var lat =; var lon = query.lon; ... }

You can also add formatter implementing the following interface

var formatter = {
    formatfunction(data) { return formattedData; },

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.
