node-where

A basic geolocation library for node.js.

Uses freegeoip.net and the Google Maps Geocoding API

Installation

npm install node-where --save

Usage

Where can search by Postal Address, landmark or IP Address:

Search by Postal Address:

var where = require('node-where');

where.is('4 yawkey way boston ma', function(err, result) {
  if (result) {
    console.log('Address: ' + result.get('address'));
    console.log('Street Number: ' + result.get('streetNumber'));
    console.log('Street: ' + result.get('street'));
    console.log('Full Street: ' + result.get('streetAddress'));
    console.log('City: ' + result.get('city'));
    console.log('State / Region: ' + result.get('region'));
    console.log('State / Region Code: ' + result.get('regionCode'));
    console.log('Zip: ' + result.get('postalCode'));
    console.log('Country: ' + result.get('country'));
    console.log('Country Code: ' + result.get('countryCode'));
    console.log('Lat: ' + result.get('lat'));
    console.log('Lng: ' + result.get('lng'));
  }
});

Search by Landmark:

var where = require('node-where');

where.is('Fenway Park', function(err, result) {
  if (result) {
    // Same result as address search
    // ...
  }
});

Search by IP Address (both IPv4 and IPv6):

var where = require('node-where');

where.is('173.194.33.104', function(err, result) {
  if (result) {
    console.log('City: ' + result.get('city'));
    console.log('State / Region: ' + result.get('region'));
    console.log('State / Region Code: ' + result.get('regionCode'));
    console.log('Zip: ' + result.get('postalCode'));
    console.log('Country: ' + result.get('country'));
    console.log('Country Code: ' + result.get('countryCode'));
    console.log('Lat: ' + result.get('lat'));
    console.log('Lng: ' + result.get('lng'));
  }
});

NOTE: IP address lookups do not include any street address information.

Usage as Express middleware:

var where = require('node-where');

app.use(function(req, res, next) {
  where.is(req.ip, function(err, result) {
    req.geoip = result;
    next();
  });
});
