NODEJS get local ip address node.js - Net-Raft.com

// at first you install "npm install ip" in node.js command prompt

//put this code into getip.js
var http = require('http');
var ip = require('ip');

var srv = http.createServer(function (req, res) {
var address = ip.address();

res.writeHead(200, {'Content-Type': 'text/plain'});
res.end(address);

});

srv.listen(3000);
console.log("Listening to Port 3000");

// type "node getip.js" in command prompt
// then put this url "http://localhost:3000/address" into any browser

// this node.js code put into app.js

const request = require('request')

request('http://ipinfo.io', function(error, res, body) {
var ipuser = JSON.parse(body)
console.log(ipuser.ip)
})

// then type "node app.js" in command prompt

// this is a functional solution, copy and use
//put this code into getip.js

// type "node getip.js" in command prompt
// then put this url "http://localhost:3000/" into any browser

// type "node script.js" in node.js command prompt

// place into script.js
