Node GeoIP Native

This package is a lightning-fast, native JavaScript geoip lookup built on MaxMind's free country database.

It is non-blocking and operates without any IO after initially loading the data into memory.

Results are 4 - 5 times faster than geoip-lite with the caveat that it takes 2 or 3 times longer to initialize and uses 60 or 70 megabytes memory.

This is used in production at Playtomic in a high volume API where performance matters.

Benchmarks on my 2011 Macbook Air whilst running lots of software. The test took the middle 10 results from 20 iterations and averaged them. The APIs are interchangeable so tests were identical.

geoip-native:    average: 1540.3ms / million lookups
geoip-lite:     average: 8375.3ms / million lookups

Requires

  1. Comes with the standard CSV database by MaxMind which may require updating.

How to use

  1. git clone https://github.com/benlowry/node-geoip-native
  2. cd node-geoip-native
  3. node test.js

or just npm install geoip-native

Methods

Node GeoIP Native provides methods for:

  1. lookup performs the lookup, takes the ip address as a parameter

Examples

var geoip = require("geoip-native");
var ip = "123.123.123.123";
geoip.lookup(ip);
console.log("country: " + ip.name + " / " + ip.code);

// in practice you'd want:
// ip = request.headers["x-forwarded-for"] || request.connection.remoteAddress,

What's missing

Be neat to expand this to include cities.
