    node-geocoder

    Build Status Dependencycy status npm version

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

    Installation (nodejs library)

    npm install node-geocoder
    

    Usage example

    var NodeGeocoder = require('node-geocoder');
     
    var options = {
      provider: 'google',
     
      // Optional depending on the providers
      httpAdapter: 'https', // Default
      apiKey: 'YOUR_API_KEY', // for Mapquest, OpenCage, Google Premier
      formatter: null         // 'gpx', 'string', ...
    };
     
    var geocoder = NodeGeocoder(options);
     
    // 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',

        level2long: 'Paris',
        level2short: '75'
      },
      provider: 'google'
    }]

    Advanced usage (only google, here, mapquest, locationiq, and opencage providers)

    geocoder.geocode({address: '29 champs elysée', country: 'France', zipcode: '75008'}, function(err, res) {
      console.log(res);
    });
     
    // OpenCage advanced usage example
    geocoder.geocode({address: '29 champs elysée', countryCode: 'fr', minConfidence: 0.5, limit: 5}, function(err, res) {
      console.log(res);
    });
     
    // Reverse example
     
    // Using callback
    geocoder.reverse({lat:45.767, lon:4.833}, function(err, res) {
      console.log(res);
    });
     
    // Or using Promise
    geocoder.reverse({lat:45.767, lon:4.833})
      .then(function(res) {
        console.log(res);
      })
      .catch(function(err) {
        console.log(err);
      });
     
    // Batch geocode
     
    geocoder.batchGeocode(['13 rue sainte catherine', 'another adress'], function (err, results) {
      // Return an array of type {error: false, value: []}
      console.log(results) ;
    });
     
    // Set specific http request headers:
    var HttpsAdapter = require('node-geocoder/lib/httpadapter/httpsadapter.js')
    var httpAdapter = new HttpsAdapter(null, {
      headers: {
        'user-agent': 'My application <email@domain.com>',
        'X-Specific-Header': 'Specific value'
      }
    });
     
    var geocoder = NodeGeocoder({
      provider: 'google',
      httpAdapter: httpAdapter
    });

    Playground

    You can try node-geocoder here http://node-geocoder.herokuapp.com/

    Command line tools

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

    Extending node geocoder

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

    var geocoder = {
        geocode: function(value, callback) { ... },
        reverse: function(query, callback) { var lat = query.lat; var lon = query.lon; ... }
    }

    You can also add formatter implementing the following interface

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

    Contributing

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

    To run tests just npm test.

    To check code style just run npm run lint.
