express get full url

To get the full URL in a Node.js application using the Express framework, you can utilize the request object and its properties. The request object provides access to information about the HTTP request, including the URL. Here are the steps to achieve this:

Step 1: Require the necessary modules

const express = require('express');

Step 2: Create an instance of the Express application

const app = express();

Step 3: Define a route and handle the request

app.get('/fullUrl', (req, res) => {
  const fullUrl = req.protocol + '://' + req.get('host') + req.originalUrl;
  res.send('Full URL: ' + fullUrl);
});

In this example, we define a route using the app.get() method, specifying the path '/fullUrl'. Inside the route handler function, we construct the full URL by combining the request's protocol, host, and original URL. Finally, we send the full URL as a response using res.send().

These steps demonstrate how to obtain the full URL in a Node.js application using the Express framework by utilizing the properties of the request object.
