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.
userId licenseKey ip callback;
Multiple calls, same account
const geoip2ws = userId licenseKey;;;
Mix products (or accounts)
const geoip2ws = ;const insights = userId licenseKey 'insights';const country = userId licenseKey 'country';// precise lookup, higher cost;// vague lookup, lower cost;
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 i geoip2ws --save
The first function is the setup and takes these settings:
|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|
// With argumentsconst geo = 1234 'abc' 'country' 2000;// Or with an objectconst geo =userId: 1234licenseKey: 'abc'service: 'country'requestTimeout: 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|
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.
|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||
|API error||API error occured||
