    Usage

    You can provide the configuration in the require function or inline at lookup time. The lookup always returns a Promise.

    Normal configuration

    const geo = require ('geoip2ws') ({
      userId: '12345',
      licenseKey: 'abc678',
    });
    
    geo ({
      service: 'city',
      ip: '1.2.3.4',
    })
      .then (console.log)
      .catch (console.error)
    ;

    Inline configuration

    const geo = require ('geoip2ws')();
    
    geo ({
      userId: '12345',
      licenseKey: 'abc678',
      service: 'city',
      ip: '1.2.3.4',
    })
      .then (console.log)
      .catch (console.error)
    ;

    Installation

    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

    The functions

    Setup

    The first function is the global config and returns the lookup function. It takes these settings:

    parameter type default description
    [userId] string User ID
    [licenseKey] string License key
    [service] string city insights, country or city
    [endpoint] string https://geoip.maxmind.com Override endpoint hostname or url
    [requestTimeout] integer 5000 Request timeout in ms
    const geo = require ('geoip2ws') ({
      userId: '1234',
      licenseKey: 'abc',
      service: 'country',
      requestTimeout: 2000
    });

    If you are providing the details in the lookup function, then you don't have to set them here but you do need to run this setup function once.

    const geo = require ('geoip2ws')();

    Lookup

    The second function does the IP-address lookup and takes ip and optionally the same settings as above.

    parameter type description
    ip string The IPv4 or IPv6 address to lookup
    geo ({
      ip: '1.2.3.4',
      service: 'city',
      endpoint: 'geoip-eu-west.maxmind.com',
    })
      .then (processData)
      .catch (console.error)
    ;

    Errors

    error message description
    invalid service The service name is invalid
    invalid ip The IP-address is invalid

    These two conditions are checked before sending the request. Meaning it won't cost you account credits.
