How to get the User's IP address in Node.js

In this tutorial, we are going to learn about how to get a local ip address of a current user in Node.js using node-ip npm package.

First, we need to install a node-ip package by using the following command.

npm install ip

Now, inside your Node.js express app, you can get an ip address like this.

const express = require("express");
const ip = require("ip");
const app = express();

app.use((req, res, next) => {
  console.log(ip.address());  next();
})

app.get("/users", (req, res) => {
  res.send('hello')
});

app.listen(3000, () => console.log(`App is running`));

Output:

192.128.33.181

Note: In the above code, we have created a middleware function that logs the ip address of every user, who access your app.
