Unofficial module for Maxmind GeoIP2 Web Services
Unofficial Node.js module for the Maxmind GeoIP2 Web Services.
There are multiple ways to load and set up this module. All communication is done over HTTPS.
require 'geoip2ws' userId licenseKey ip callback;
var geo = require 'geoip2ws' userId licenseKey;geo ip1 callback;geo ip2 callback;
var insights = 'geoip2ws' userId licenseKey 'insights';var country = 'geoip2ws' userId licenseKey 'country';// precise lookup, higher costinsights ip callback;// vague lookup, lower costcountry ip callback;
You need a Maxmind account ID and license key with enough credits for one of their GeoIP web services. You can find both here.
npm install geoip2ws
npm install fvdm/nodejs-geoip2ws#develop
The first function is the setup and takes these arguments:
|userId||string||yes||Your Maxmind account user ID|
|licenseKey||string||yes||Your Maxmind account license key|
|service||string||no||The service you'd like to use: |
|requestTimeout||integer||no||Socket read timeout in milliseconds to wait for reply from MaxMind|
var geo = require 'geoip2ws' 1234 'abc' 'country' 2000;
The second function does the IP-address lookup and takes these arguments:
|service||string||no||The service, same as above|
|ip||string||yes||The IPv4 or IPv6 address to lookup|
|callback||function||yes||Your callback |
geo 'city' '184.108.40.206' myCallback;
The callback function receives result data and errors. Unless an error occurs the
data JSON will be parsed to an object. When everything is ok
err is an instance of
Error. It also returns API errors this same way.
if errconsole.log err errstack;elseconsole.log datacitynamesen;
|no userId or licenseKey||You did not set your credentials|
|invalid service||The service name is invalid||no credits used|
|invalid ip||The IP-address is invalid||no credits used|
|request failed||A request error occured|
|request timeout||Request took too long|
|request dropped||API cancelled the request|
|no data||API response was empty|
|not json||API response was not in JSON|
|API error||API error occured|
