How to Get Request IP in Express Server

To get the request IP in an Express server, you can use the req.ip property. Here are the steps to do it:

  1. Import the Express module: Begin by importing the Express module in your JavaScript file. This can be done using the require function: javascript const express = require('express');

  2. Create an Express app: Create an instance of the Express application by calling the express function: javascript const app = express();

  3. Define a route: Define a route in your Express app using the app.get method. This route will handle incoming GET requests: javascript app.get('/', (req, res) => { // Code to get the request IP });

  4. Get the request IP: Inside the route handler function, you can access the request IP using the req.ip property. This property contains the IP address of the client making the request: javascript app.get('/', (req, res) => { const ipAddress = req.ip; // Use the ipAddress as needed });

That's it! You can now use the ipAddress variable to access the IP address of the client making the request.

Please note that the req.ip property may return the IP address of a proxy server if your Express app is behind a reverse proxy. If you want to get the IP address of the client directly, you can use the req.headers['x-forwarded-for'] property instead.
