Installing and Managing Node.js with NVM: A Comprehensive Guide

Node.js is a popular JavaScript runtime environment used for developing server-side applications. With its growing popularity, managing different versions of Node.js has become essential for developers. This guide will walk you through the installation and management of Node.js using NVM (Node Version Manager), a command-line tool that simplifies the process.

To list all the versions of Node.js installed on your system, execute the following command: `$ nvm ls`. Here, we are installing Node.js v14.18.0. You can also specify a specific version of Node.js by specifying the version number. In our case, the latest version – v16.10.0 – is already installed.

If you want to install the latest LTS (Long Term Support) version, run the command: `$ nvm install node -lts`. To install the most recent version of Node.js, run the following command with ‘node’ as the alias for the latest version.

NVM allows developers to install multiple versions of Node.js. This means that you can have multiple installations of Node.js in a single account and decide which version to use for your project. The installation of Node.js is user-account specific, so each user account can have its own independent installation.

To install NVM, you need to download and run the NVM bash script as follows: `$ curl | bash`. Once installed, you can verify that NVM has been successfully installed by running the command `$ nvm ls`.

In this guide, we will focus on installing Node.js using the NVM utility. One of the ways of installing Node.js is using the APT package manager which installs it from Debian repositories. However, this does not always install the latest version.

To manage multiple versions of Node.js, you can use the following commands:

* `$ nvm ls` to list all installed versions

* `$ nvm install ` to install a specific version

* `$ nvm uninstall ` to uninstall a specific version

* `$ nvm use ` to switch between different versions

NVM also allows you to specify the default version of Node.js by running the command: `$ nvm alias default `. This sets the default version of Node.js that will be used when you run the command `node` without specifying a version.

In conclusion, NVM provides an easy way to manage multiple versions of Node.js on your system. By following this guide, you can install and manage different versions of Node.js using NVM.
