geotools's Introduction

geotools

Simple and fast IP to Country/Region lookup module for nodejs. Pull Requests are welcome!

GEO databases

You can download fresh geo database from this website: http://ipgeobase.ru/. Database contains major ranges for all countries worldwide and precise ranges for most Russian cities/regions. It could also be extended with other generic geo data.

Installation

npm install geotools

Usage

var geo = require('geotools');
var res = geo.lookup('87.229.134.24');
/**
  * Output is: 
  * {
  *    country: 'RU',
  *    region: 1056,
  *    city: 'Березовский',
  *    regionName: 'Свердловская область',
  *    district: 'Уральский федеральный округ',
  *    lat: '56.912811',
  *    lon: '60.804699',
  *    utcOffset: '+05:00'
  *  }
 */

Speed / Benchmark

Approximate speed on average laptop is about 1.5M calls per second. Benchmark is simple, but it gives you an idea about module's performance. Test it yourself:

node ./lib/bench.js

geotools's Issues

Improvement: lookup to return full record, not country/id

Привет.
Я сделал небольшой плагин, чтобы можно было не только страну таскать, но и город

geo = require "geotools"
Iconv   = require('iconv').Iconv
fs      = require "fs"
rindex  = {}

GEO_DIR_DATA        = "./node_modules/geotools/geo"
iconv = new Iconv "windows-1251", "utf-8"
pidr = fs.readFileSync GEO_DIR_DATA + "/cities.txt"
pidr = iconv.convert pidr
pidr = pidr.toString().split('\n');


for p in [0...pidr.length - 1] by 1
    row = pidr[p].split "\t"
    rindex[row[0]] = 
        city: row[1]
        area: row[2]
        region: row[3]
        lattitude: row[4]
        longtitude: row[5]


module.exports  = (r) ->
    r.ipCountry = geo.lookup r.connection.remoteAddress
    if r.ipCountry?.region? and r.ipCountry.country is "RU"
        r.ipLocation = rindex[r.ipCountry.region]
    else
        r.ipLocation = null
    r.next()

В процессе тестирования выявил, что результаты работы geotools не соответстуют результатам с ipgeobase.ru (базы взял последние) напишу отдельно

Многие ip-адреса не определяются

Вот список:

78.36.146.173
78.36.146.226
78.36.147.65
78.36.144.170
78.36.145.100
46.52.177.163

Каждый ip распознается корректно через веб-интерфейс ipgeobase, и некорректно (null) с помощью geotools. Базу я обновлял до последней актуальной.
