jGeoIP
jGeoIP is a light Javascript API for reading new MaxMind's DB files (mmdb). jGeoIP stores the complete database in memory to speed up the performances. Besides, it implements a LRU (Least Recently Used) cache for optimizing reading performances for the most recently used IPs.
Usage
var jGeoIP = require('jgeoip');
// Load synchronously MaxMind database in memory
var geoip = new jGeoIP('path/to/maxmind.mmdb');
// IPV4
geoip.getRecord('8.8.8.8');
//IPV6
geoip.getRecord('2001:4860:4860::8844');
API
.getMetadata()
returns MaxMind's database metadata,.getRecord(IP)
returns IP data.
