How to usehost Property in Express

We are going to use the host property which is the request object that can be used to access the hostname which is specified in the HTTP request.
Using this method, we can directly receive the host information without relying on any other specific header.

Syntax:

const originDomain = req.get('host');

Example: Below is the implementation of the above-discussed approach.

Javascript

//app.js
 
const express = require('express');
const app = express();
app.use((req, res, next) => {
    const originDomain = req.get('host');
    console.log('Origin Domain:', originDomain);
    next();
});
 
app.get('/', (req, res) => {
    res.send('Hello, w3wiki. Domain is in Terminal');
});
 
app.listen(3000, () => {
    console.log('Server is running on port 3000');
});
