Step 2: Install Node.js

Once the system packages are updated, you can proceed with the installation of Node.js. There are multiple methods to install Node.js on Ubuntu, but we will cover the most common and recommended approach using the NodeSource repository.

Step 2.1: Add the NodeSource Repository

Step 2.1: Add the NodeSource Repository

To add the NodeSource repository, you need to run a specific command in the Terminal. This command is curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash -. Let’s break down what this command does:

  • curl: This command is used to transfer data from or to a server. In this case, it is used to download the script that adds the NodeSource repository.
  • -sL: These flags are used with the curl command. The -s flag stands for “silent” and prevents curl from showing progress or error messages. The -L flag tells curl to follow any redirects.
  • https://deb.nodesource.com/setup_14.x: This is the URL from which the script is downloaded. It points to the NodeSource repository.
  • sudo -E bash -: This part of the command executes the downloaded script with elevated privileges using sudo. The -E flag preserves the user’s environment variables, and bash - runs the script using the Bash shell.

By running this command in the Terminal, you are effectively adding the NodeSource repository to your Ubuntu system. This repository contains the necessary packages for installing Node.js.

Step 2.2: Install Node.js and npm

After adding the NodeSource repository, you can proceed with the installation of Node.js and npm. To install both packages, open the Terminal and run the following command:

sudo apt install -y nodejs

. This command will download and install the latest version of Node.js and npm on your Ubuntu system.

By installing Node.js, you gain access to a powerful JavaScript runtime environment that allows you to build scalable and efficient web applications. Node Package Manager (npm) is also installed, which provides a vast ecosystem of libraries and modules that you can easily incorporate into your projects.

Step 3: Verify the Installation

After successfully installing Node.js and npm on your Ubuntu system, it is important to verify that they are installed correctly. This can be done by running a few simple commands in the Terminal.

To check the version of Node.js installed, open the Terminal and type node -v. Press Enter and the installed version of Node.js will be displayed. If a version number is displayed, it means Node.js is installed correctly.

Similarly, to check the version of npm installed, type npm -v in the Terminal and press Enter. The installed version of npm will be displayed. If a version number is displayed, it means npm is installed correctly.

Verifying the installation of Node.js and npm ensures that you can start building and running web applications using this powerful JavaScript runtime. If you encounter any issues during the verification process, you may need to troubleshoot the installation or seek further assistance.

Step 3.1: Check Node.js Version

In order to check the version of Node.js installed on your Ubuntu system, you need to open the Terminal. To do this, simply type “node -v” in the Terminal and press Enter. This command will display the version number of Node.js that is installed on your system.

If you see a version number displayed after running the command, it means that Node.js is installed correctly and you are good to go. However, if you don’t see any version number or encounter an error message, it indicates that Node.js is not installed or not installed properly.

Checking the Node.js version is an important step to ensure that your system is ready to run Node.js applications and take advantage of its features and functionalities.

Step 3.2: Check npm Version

Step 3.2: Check npm Version

In order to check the version of npm installed on your Ubuntu system, you need to open the Terminal. To do this, type “npm -v” in the Terminal and press Enter.

Once you press Enter, the Terminal will display the version number of npm. If a version number is displayed, it means that npm is installed correctly on your system.

This step is crucial to ensure that npm is functioning properly and that you can use it to manage your Node.js packages effectively.
