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 geoip2ws = require ('geoip2ws') (userId, licenseKey);
geoip2ws (ip1, callback);
geoip2ws (ip2, callback);
var geoip2ws = require ('geoip2ws');
var insights = new geoip2ws (userId, licenseKey, 'insights');
var country = new geoip2ws (userId, licenseKey, 'country');
// precise lookup, higher cost
insights (ip, callback);
// vague lookup, lower cost
country (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
The first function is the setup and takes these settings:
parameter | type | required | description |
---|---|---|---|
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: insights , country , city (default) |
requestTimeout | integer | no | Socket read timeout in milliseconds to wait for reply from MaxMind |
// With arguments
var geo = require ('geoip2ws') (1234, 'abc', 'country', 2000);
// Or with an object
var geo = require ('geoip2ws') ({
userId: 1234,
licenseKey: 'abc',
service: 'country',
requestTimeout: 2000
});
The second function does the IP-address lookup and takes these arguments:
parameter | type | required | description |
---|---|---|---|
service | string | no | The service, same as above |
ip | string | yes | The IPv4 or IPv6 address to lookup |
callback | function | yes | Your callback function to receive the data |
geo ('city', '145.53.252.135', 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 null
else
err
is an instance of Error
. It also returns API errors this same way.
function myCallback (err, data) {
if (err) {
console.log (err);
} else {
console.log (data.city.names.en);
}
}
error message | description | additional |
---|---|---|
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 | err.error |
API error | API error occured | err.code and err.error |
