geoip-lite

What is geoip-lite?

The geoip-lite npm package provides a fast and lightweight IP geolocation library for Node.js. It allows you to look up the geographic location of an IP address, including country, region, and city information. The package uses a local database, which means it does not require an external service or API call, making it suitable for high-performance applications.

What are geoip-lite's main functionalities?

IP to Country Lookup

This feature allows you to look up the country associated with a given IP address. The code sample demonstrates how to use the `lookup` method to retrieve the country code for the IP address '207.97.227.239'.

const geoip = require('geoip-lite');
const ip = '207.97.227.239';
const geo = geoip.lookup(ip);
console.log(geo.country); // Output: 'US'

IP to City Lookup

This feature allows you to look up the city associated with a given IP address. The code sample demonstrates how to use the `lookup` method to retrieve the city name for the IP address '207.97.227.239'.

const geoip = require('geoip-lite');
const ip = '207.97.227.239';
const geo = geoip.lookup(ip);
console.log(geo.city); // Output: 'San Antonio'

IP to Region Lookup

This feature allows you to look up the region (state or province) associated with a given IP address. The code sample demonstrates how to use the `lookup` method to retrieve the region code for the IP address '207.97.227.239'.

const geoip = require('geoip-lite');
const ip = '207.97.227.239';
const geo = geoip.lookup(ip);
console.log(geo.region); // Output: 'TX'

IP to Latitude and Longitude Lookup

This feature allows you to look up the latitude and longitude coordinates associated with a given IP address. The code sample demonstrates how to use the `lookup` method to retrieve the coordinates for the IP address '207.97.227.239'.

const geoip = require('geoip-lite');
const ip = '207.97.227.239';
const geo = geoip.lookup(ip);
console.log(geo.ll); // Output: [29.4889, -98.3987]

Other packages similar to geoip-lite

maxmind

The maxmind package provides access to MaxMind's GeoIP2 and GeoLite2 databases. It offers more detailed and accurate geolocation data compared to geoip-lite, but requires downloading and updating the database files regularly. It also supports additional data points such as ISP and organization information.

ipstack

The ipstack package is a wrapper for the ipstack API, which provides IP geolocation data. It offers a wide range of data points, including country, region, city, ZIP code, latitude, longitude, and more. Unlike geoip-lite, it requires an API key and makes external HTTP requests, which may introduce latency.

ipinfo

The ipinfo package is a client for the IPinfo.io API, which provides IP geolocation and other related data. It offers detailed information such as country, region, city, postal code, latitude, longitude, and ASN. Similar to ipstack, it requires an API key and makes external HTTP requests.
