IPinfo NodeJS Client Library

This is the official NodeJS client library for the IPinfo.io IP data API, allowing you to lookup 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 install node-ipinfo

Usage

TypeScript

import IPinfoWrapper, { IPinfo, AsnResponse } from "node-ipinfo";

const ipinfoWrapper = new IPinfoWrapper("MY_TOKEN");

ipinfoWrapper.lookupIp("1.1.1.1").then((response: IPinfo) => {
    console.log(response);
});

ipinfoWrapper.lookupASN("AS7922").then((response: AsnResponse) => {
    console.log(response);
});

JavaScript

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

let ipinfo = new IPinfoWrapper("MY_TOKEN");

ipinfo.lookupIp("1.1.1.1").then((response) => {
    console.log(response);
});

ipinfo.lookupASN("AS7922").then((response) => {
    console.log(response);
});

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 defauly max number of items allowed in the cache is 5000. This can be changed by passing an Option to the LruCache constructor.

TypeScript

import IPinfoWrapper, { LruCache, Options } from "node-ipinfo";

const cacheOptions: Options<string, any> = {
    max: 5000,
    maxAge: 24 * 1000 * 60 * 60,
};
let cache = new LruCache(cacheOptions);
let ipinfoWrapper = new IPinfoWrapper("MY_TOKEN", cache);

JavaScript

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

let cacheOptions = {
    max: 5000,
    maxAge: 24 * 1000 * 60 * 60,
};
let cache = new LruCache(cacheOptions);
let ipinfo = 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.

TypeScript

import IPinfoWrapper from "node-ipinfo";

// 10 second timeout.
let ipinfoWrapper = new IPinfoWrapper("MY_TOKEN", null, 10000);

JavaScript

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

// 10 second timeout.
let ipinfo = new IPinfoWrapper("MY_TOKEN", null, 10000);
