    IPinfo 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
    const { IPinfoWrapper } = require("node-ipinfo");
    
    const 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,
    };
    const cache = new LruCache(cacheOptions);
    const ipinfoWrapper = new IPinfoWrapper("MY_TOKEN", cache);
    JavaScript
    const { IPinfoWrapper, LruCache } = require("node-ipinfo");
    
    const cacheOptions = {
        max: 5000,
        maxAge: 24 * 1000 * 60 * 60,
    };
    const cache = new LruCache(cacheOptions);
    const 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.
    const ipinfoWrapper = new IPinfoWrapper("MY_TOKEN", null, 10000);
    JavaScript
    const { IPinfoWrapper } = require("node-ipinfo");
    
    // 10 second timeout.
    const ipinfo = new IPinfoWrapper("MY_TOKEN", null, 10000);

    Errors

    TypeScript
    import IPinfoWrapper, { IPinfo, ApiLimitError } from "node-ipinfo";
    
    const ipinfoWrapper = new IPinfoWrapper("MY_TOKEN");
    
    ipinfoWrapper.lookupIp("1.1.1.1").then((response: IPinfo) => {
        console.log(response);
    })
    .catch((error) => {
        console.log(error);
        if (error instanceof ApiLimitError) {
            // handle api limit exceed error
        } else {
            // handle other errors
        }
    });
    JavaScript
    const { IPinfoWrapper, ApiLimitError } = require("node-ipinfo");
    
    const ipinfo = new IPinfoWrapper("MY_TOKEN");
    
    ipinfo.lookupIp("1.1.1.1").then((response) => {
        console.log(response);
    },
    (error) => {
        console.log(error);
        if (error instanceof ApiLimitError){
            // handle api limit exceed error
        } else {
            // handle other errors
        }
    });

    Country Name Lookup

    response.country will return the country name, whereas response.countryCode can be used to fetch country code.

    Additionally response.isEU will return true if the country is a member of the European Union (EU), response.countryFlag will return emoji and unicode of country's flag, response.countryCurrency will return code and symbol of country's currency and response.continent will return the continent of IP.

    TypeScript
    import IPinfoWrapper, { IPinfo } from "node-ipinfo";
    
    const ipinfoWrapper = new IPinfoWrapper("MY_TOKEN");
    
    ipinfoWrapper.lookupIp("1.1.1.1").then((response: IPinfo) => {
        // country code, e.g. 'US'
        console.log(response.countryCode);
    
        // country name, e.g. 'United States'
        console.log(response.country);
    
        // whether part of the EU, e.g. false 
        console.log(response.isEU);
    
        // emoji and unicode of country flag { emoji: '🇺🇸', unicode: 'U+1F1FA U+1F1F8' }
        console.log(response.countryFlag)
    
        // code and symbol of country currency { code: 'USD', symbol: '$' }
        console.log(response.countryCurrency)
    
        // code and name of continent { code: 'NA', name: 'North America' }
        console.log(response.continent)
    });
    JavaScript
    const { IPinfoWrapper } = require("node-ipinfo");
    
    const ipinfo = new IPinfoWrapper("MY_TOKEN");
    
    ipinfo.lookupIp("1.1.1.1").then((response) => {
        // country code, e.g. 'US'
        console.log(response.countryCode);
    
        // country name, e.g. 'United States'
        console.log(response.country);
    
        // whether part of the EU, e.g. false 
        console.log(response.isEU);
        
        // emoji and unicode of country flag { emoji: '🇺🇸', unicode: 'U+1F1FA U+1F1F8' }
        console.log(response.countryFlag)
    
        // code and symbol of country currency { code: 'USD', symbol: '$' }
        console.log(response.countryCurrency)
    });

    Location Information

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

    TypeScript
    import IPinfoWrapper, { IPinfo } from "node-ipinfo";
    
    const ipinfoWrapper = new IPinfoWrapper("MY_TOKEN");
    
    ipinfoWrapper.lookupIp("1.1.1.1").then((response: IPinfo) => {
        // '34.0522,-118.2437'
        console.log(response.loc);
    });
    JavaScript
    const { IPinfoWrapper } = require("node-ipinfo");
    
    const ipinfo = new IPinfoWrapper("MY_TOKEN");
    
    ipinfo.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.

    TypeScript
    import IPinfoWrapper, { MapResponse } from "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: MapResponse) => {
        console.log(response);
    });
    JavaScript
    const { IPinfoWrapper } = require("node-ipinfo");
    
    const ipinfo = new IPinfoWrapper("MY_TOKEN");
    
    const ips = ["1.1.1.1", "8.8.8.8", "1.2.3.4"]; 
    ipinfo.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.

    TypeScript
    import IPinfoWrapper, { BatchResponse } from "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((response: BatchResponse) => {
        console.log(response);
    });
    JavaScript
    const { IPinfoWrapper } = require("node-ipinfo");
    
    const ipinfo = new IPinfoWrapper("MY_TOKEN");
    
    const ips = ["1.1.1.1", "8.8.8.8", "1.2.3.4/country"]; 
    ipinfo.getBatch(ips).then((response) => {
        console.log(response);
    });

    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.
