If you are a developer working with Node.js, you know how important it is to have multiple versions of Node.js installed on your system. This allows you to test your code against different versions and ensure compatibility. One of the best tools for managing multiple Node.js versions is nvm (Node Version Manager).
nvm is a command-line tool that allows you to easily install, manage, and switch between different versions of Node.js. It provides a simple and convenient way to install specific Node.js versions, as well as switch between them with just a few commands.
In this step-by-step guide, we will walk you through the process of installing nvm on Ubuntu. By the end of this guide, you will have nvm installed on your system and be able to start managing your Node.js versions with ease.
What is nvm?
nvm stands for Node Version Manager. It is a command-line tool that allows you to easily manage multiple versions of Node.js on your Ubuntu system. With nvm, you can install and switch between different versions of Node.js with just a few simple commands.
Node.js is a popular JavaScript runtime built on Chrome’s V8 JavaScript engine. It allows you to run JavaScript code on the server-side, making it a powerful tool for building web applications. However, different projects may require different versions of Node.js, and managing these versions manually can be a hassle.
That’s where nvm comes in. It provides a convenient way to install, manage, and switch between different versions of Node.js. With nvm, you can easily switch between different Node.js versions depending on the requirements of your projects. This makes it easier to ensure compatibility and maintain consistency across your development environment.
