After adding the PPA, we can now install Node.js. Enter the following command in the terminal:

sudo apt-get install nodejs

This command will download and install the latest version of Node.js. After the installation is complete, we can check whether Node.js is fully installed using the following command:

node -v

If you see the version number in the terminal, Node.js has been installed successfully.

2. Install Npm

Npm (Node Package Manager) is a software package manager used to manage Node.js software packages. We need to install it to manage Node.js packages.

1. Install npm through apt

We can use the apt command to install npm on Ubuntu. Enter the following command in the terminal:

sudo apt-get install npm

This command will install the latest version of npm. Once completed, we can check if npm is fully installed using the following command:

npm -v

npm install express

This command will install the latest version of Express. After the installation is complete, we can check the version number using the following command:

npm list express
