Unofficial Node.js module for the Maxmind GeoIP2 Web Services.
The configuration parameters must be wrapped in an object.
This allows the use of spread { ...config, ip: '1.2.3.4' }
if you want to keep the main config in a variable.
The lookup always returns a Promise.
const geo = require( 'geoip2ws' );
geo( {
userId: '12345',
licenseKey: 'abc678',
service: 'city',
ip: '1.2.3.4',
} )
.then( console.log )
.catch( console.error )
;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
| parameter | type | default | description |
|---|---|---|---|
| userId | string | User ID | |
| licenseKey | string | License key | |
| [ip] | string | me | The IP address or 'me' for your current IP |
| [service] | string | city | insights, country or city |
| [endpoint] | string | https://geoip.maxmind.com | Override endpoint url, include the protocol prefix |
| [timeout] | number | 5000 | Request timeout in ms |
{
ip: '2a02:abc:def::123',
userId: '1234',
licenseKey: 'abc',
service: 'country',
timeout: 2000,
}You can change the endpoint to use a http proxy or target a specific datacenter.
Make sure to prefix the hostname with the protocol, i.e. https://.
For the GeoLite2 web service set the endpoint to https://geolite.info.
Errors from the request or API are thrown and can be caught in the Promise.
For API errors the message is prefixed with API: string.
