IPinfo IPinfo NodeJS Client Library

This is the official NodeJS client library for the IPinfo.io IP data API, allowing you to look up your own IP address, or get any of the following details for an IP:

  • IP geolocation data (city, region, country, postal code, latitude, and longitude)
  • ASN details (ISP or network operator, associated domain name, and type, such as business, hosting, or company)
  • Company data (the name and domain of the business that uses the IP address)
  • Carrier information (the name of the mobile carrier and MNC and MCC for that carrier if the IP is used exclusively for mobile traffic)

Check all the data we have for your IP address here.

Works with ES5, ES6+ and TypeScript.

Getting Started

You'll need an IPinfo API access token, which you can get by signing up for a free account at https://ipinfo.io/signup.

The free plan is limited to 50,000 requests per month, and doesn't include some of the data fields such as IP type and company data. To enable all the data fields and additional request volumes see https://ipinfo.io/pricing.

Installation

npm

npm install node-ipinfo

yarn

yarn add node-ipinfo

Usage

  1. Initialize an instance of IPinfoWrapper with your token.
const { IPinfoWrapper } = require("node-ipinfo");

const ipinfoWrapper = new IPinfoWrapper("MY_TOKEN");

Tip

If you are using ESM instead of CommonJS you can use import.

import { IPinfoWrapper } from "node-ipinfo";
  1. Perform a lookup for an IP address or ASN.
const ipinfo = await ipinfoWrapper.lookupIp("1.1.1.1");
Standalone example
  1. Create ipinfo.js with the following code, then replace MY_TOKEN with your token.
const { IPinfoWrapper } = require("node-ipinfo");

const ipinfoWrapper = new IPinfoWrapper("MY_TOKEN");

const ipAddress = process.argv[2] || "1.1.1.1";

ipinfoWrapper.lookupIp(ipAddress).then((ipinfo) => console.log(ipinfo));
  1. Run ipinfo.js (without an IP) to lookup 1.1.1.1.
node ipinfo.js
{
  ip: '1.1.1.1',
  // ...
  1. Run ipinfo.js with an IP to lookup, like 2.2.2.2 8.8.8.8 or your IP.
node ipinfo.js 2.2.2.2
{
  ip: '2.2.2.2',
  // ...

Best practices

Each lookup method will throw an error when the lookup does not complete successfully. A program that performs a lookup should catch errors unless it is desirable for the error to bubble up. For example, if your program is performing a lookup to find the country code of an IP you can return "N/A" when catching an error.

const countryCode = ipinfoWrapper
    .lookupIp("1.1.1.1")
    .then((ipinfo) => ipinfo.countryCode)
    .catch((error) => "N/A");

Caching

This library uses an LRU cache (deletes the least-recently-used items).

If you prefer a different caching methodology, you may use the IPCache interface through TypeScript and implement your own caching system around your own infrastructure.

The default cache length is 1 day and the default max number of items allowed in the cache is 5000. This can be changed by passing an Option to the LruCache constructor.

const { IPinfoWrapper, LruCache } = require("node-ipinfo");

const cacheOptions = {
    max: 5000,
    ttl: 24 * 1000 * 60 * 60
};

const cache = new LruCache(cacheOptions);

const ipinfoWrapper = new IPinfoWrapper("MY_TOKEN", cache);

Timeouts

The client constructor accepts a timeout parameter in milliseconds that controls the timeout of requests. It defaults to 5000 i.e. 5 seconds.

A timeout of 0 disables the timeout feature.

const { IPinfoWrapper } = require("node-ipinfo");

const timeout = 10 * 1000; // 10 seconds

const ipinfoWrapper = new IPinfoWrapper("MY_TOKEN", undefined, timeout);

Internationalization

When looking up an IP address, the response object includes response.country will return the country name, response.countryCode can be used to fetch the country code, Additionally response.isEU will return true if the country is a member of the European Union (EU), response.countryFlag will return the emoji and Unicode of the country's flag, response.countryFlagURL will return a public link to the country's flag image as an SVG which can be used anywhere, response.countryCurrency will return the code and symbol of the country's currency and response.continent will return the continent of the IP. It is possible to return the country name in other languages, change the EU countries, countries flags, countries currencies, and continents by setting the countries, euCountries, countriesFlags, countriesCurrencies and continents settings when creating the IPinfo object.

const { IPinfoWrapper } = require("node-ipinfo");

const internationalization = {
    countries: {
        US: "United States",
        FR: "France",
        BD: "Bangladesh"
        // ...
    },
    countriesFlags: {
        US: { emoji: "🇺🇸", unicode: "U+1F1FA U+1F1F8" },
        AD: { emoji: "🇦🇩", unicode: "U+1F1E6 U+1F1E9" },
        AE: { emoji: "🇦🇪", unicode: "U+1F1E6 U+1F1EA" }
        // ...
    },
    countriesCurrencies: {
        US: { code: "USD", symbol: "$" },
        AD: { code: "EUR", symbol: "€" },
        AE: { code: "AED", symbol: "د.إ" }
        // ...
    },
    continents: {
        US: { code: "NA", name: "North America" },
        BD: { code: "AS", name: "Asia" },
        BE: { code: "EU", name: "Europe" }
        // ...
    },
    euCountries: ["FR", "ES", "BE"]
};

const ipinfoWrapper = new IPinfoWrapper(
    "MY_TOKEN",
    undefined,
    undefined,
    internationalization
);

ipinfoWrapper.lookupIp("8.8.8.8").then((response) => console.log(response));
{
  ip: "8.8.8.8",
  // ...
  countryCode: 'US',
  countryFlag: { emoji: '🇺🇸', unicode: 'U+1F1FA U+1F1F8' },
  countryFlagURL: 'https://cdn.ipinfo.io/static/images/countries-flags/US.svg',
  countryCurrency: { code: 'USD', symbol: '$' },
  continent: { code: 'NA', name: 'North America' },
  isEU: false
}

Location Information

response.loc will return a composite string of latitude and longitude values in the "latitude,longitude" format.

const { IPinfoWrapper } = require("node-ipinfo");

const ipinfoWrapper = new IPinfoWrapper("MY_TOKEN");

ipinfoWrapper.lookupIp("1.1.1.1").then(response => {
    // '34.0522,-118.2437'
    console.log(response.loc);
});

Locate IPs on a World Map

A world map can be generated with locations of all input IPs using getMap. It returns the URL of the map in the response.

const { IPinfoWrapper } = require("node-ipinfo");

const ipinfoWrapper = new IPinfoWrapper("MY_TOKEN");

const ips = ["1.1.1.1", "8.8.8.8", "1.2.3.4"]; 
ipinfoWrapper.getMap(ips).then(response => {
    console.log(response);
});

Batch Operations

Looking up a single IP at a time can be slow. It could be done concurrently from the client side, but IPinfo supports a batch endpoint to allow you to group together IPs and let us handle retrieving details for them in bulk for you.

const { IPinfoWrapper } = require("node-ipinfo");

const ipinfoWrapper = new IPinfoWrapper("MY_TOKEN");

const ips = ["1.1.1.1", "8.8.8.8", "1.2.3.4/country"]; 

ipinfoWrapper
    .getBatch(ips)
    .then(batch => console.log(batch));

The input size is not limited, as the interface will chunk operations for you behind the scenes.

Please see the official documentation for more information and limitations.

Integrated Typescript Typings

Get great code completion for this package using the integrated typescript typings. It includes the complete typings of the IPinfo API too, so you'll know how to navigate both the API as well as the response you are getting.

Running tests

In order to run the tests, run:

$ npm run test

Other Libraries

There are official IPinfo client libraries available for many languages including PHP, Python, Go, Java, Ruby, and many popular frameworks such as Django, Rails, and Laravel. There are also many third-party libraries and integrations available for our API.
