How to get my external IP address with node.js?

Question

I\'m using node.js and I need to get my external IP address, provided by my ISP. Is there a way to achieve this without using a service like http://myexternalip.com/raw ?

Answer 1

node.js has a lot of great built in modules you can use without including any external dependencies. you can make this file.
WhatsMyIpAddress.js

const http = require('http');

function WhatsMyIpAddress(callback) {
    const options = {
        host: 'ipv4bot.whatismyipaddress.com',
        port: 80,
        path: '/'
    };
    http.get(options, res => {
        res.setEncoding('utf8');
        res.on("data", chunk => callback(chunk, null));
    }).on('error', err => callback(null, err.message));
}

module.exports = WhatsMyIpAddress;

Then call it in your main.js like this.

main.js

const WhatsMyIpAddress = require('./src/WhatsMyIpAddress');
WhatsMyIpAddress((data,err) => {
   console.log('results:', data, err);
});
