How to Redirect User in Node.js Express Application Full Example

To redirect a user in a Node.js Express application, you can use the redirect method provided by the Express framework. Here’s a full example demonstrating how to redirect a user from one route to another:

Step 1: Set up a new Node.js project and install the Express package.

Create a new directory for your project, navigate to it in a terminal, and run the following commands:

npm init -y

npm i express

Step 2: Create an app.js file and set up a basic Express application.

Inside the project directory, create a new file named app.js and add the following code:

const express = require('express');
const app = express();

// Define a route
app.get('/home', (req, res) => {
  res.send('Welcome to the home page');
});

// Redirect route
app.get('/redirect', (req, res) => {
  res.redirect('/home');
});

// Start the server
app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

const express = require('express');

const app = express();

// Define a route

app.get('/home', (req, res) => {

res.send('Welcome to the home page');

});

// Redirect route

app.get('/redirect', (req, res) => {

res.redirect('/home');

});

// Start the server

app.listen(3000, () => {

console.log('Server is running on port 3000');

});

In the above code, we import the Express package and create an instance of the Express application. We define a route /home that sends a simple message. Then, we define a /redirect route that uses the redirect method to redirect the user to the /home route. Finally, we start the server on port 3000 and log a message to indicate that the server is running.

Step 3: Start the server and test the redirection.

Save the app.js file, go to the project directory in a terminal, and run the following command:
