Step 1: Add Node.js PPA

You are required to add Node.js PPA to your system provided by the Nodejs official website. We also need to install the software-properties-common package if not installed already. You can choose either to install the latest Node.js version or LTS version.

• For Latest Release

  sudo apt-get install curl software-properties-common 
  curl -sL https://deb.nodesource.com/setup_23.x | sudo bash - 
  

• For LTS Release

  sudo apt-get install curl software-properties-common 
  curl -sL https://deb.nodesource.com/setup_22.x | sudo bash - 
  

Step 2 – Install Node.js on Debian

Remember that installing the Node.js from Debian repository configured globally on system. Which is good to go on production environment where you only need single Node version. For the developer systems, you may need to install more than one Node version. Which can be do by installing Node.js using NVM.

After adding the required PPA to your system, install the Nodejs package. NPM will also be installed with node.js. This command will also install many other dependent packages on your system.

sudo apt-get install nodejs

Step 3 – Check Node.js Version

After completing the installation, check and verify the installed version of Node.js and NPM. You can find more details about current version on node.js official website.

node -v

v23.3.0

Also, check the version of NPM.

npm -v

10.9.0

Step 4 – Create Demo Web Server (Optional)

Test your Node.js installation by setting up a simple web server. Create a file http_server.js with basic code to display “Hello World!” and run it:

nano http_server.js 

and add the following content

const http = require('http');

const hostname = '127.0.0.1';
const port = 3000;

const server = http.createServer((req, res) => {
  res.statusCode = 200;
  res.setHeader('Content-Type', 'text/plain');
  res.end('Hello World\n');
});

server.listen(port, hostname, () => {
  console.log(`Server running at http://${hostname}:${port}/`);
});

Press “CTRL + O” to save changes and then press “CTRL + X” to close file and go back to terminal. Now use the following command to run above Node script:

node http_server.js 

Server running at http://127.0.0.1:3000/

The web server has been started on port 3000. Now access http://127.0.0.1:3000/ url in browser.

Conclusion

Installing Node.js on Debian systems is straightforward and allows users to leverage the power of Node.js for various applications. The process involves adding the official Node.js PPA, installing the software, and verifying the installation. Users also have the flexibility to choose between the latest or LTS versions based on their requirements. The optional step of creating a demo server can help in confirming the successful installation and functionality of Node.js.
