How to Install Node.js with NVM

Node.js is a powerful JavaScript runtime built on Chrome’s V8 JavaScript engine. It allows developers to run JavaScript code outside of a web browser, making it ideal for server-side applications. NVM, short for Node Version Manager, is a tool that allows you to easily install and manage multiple versions of Node.js on your system. In this guide, we’ll walk you through the process of installing Node.js with NVM.

Introduction to Node.js and NVM

What is Node.js?

Node.js is an open-source, cross-platform JavaScript runtime environment that executes JavaScript code outside of a web browser. It provides developers with a runtime environment for building fast and scalable network applications. Node.js uses an event-driven, non-blocking I/O model, making it efficient and lightweight.

What is NVM?

NVM, or Node Version Manager, is a command-line utility that allows you to manage multiple versions of Node.js on your system. With NVM, you can easily install, switch between, and manage different Node.js versions with a single command.

Why use NVM to install Node.js?

Using NVM to install Node.js offers several benefits:

• Flexibility: NVM allows you to install and switch between multiple Node.js versions effortlessly.
• Isolation: Each Node.js version installed with NVM is isolated from others, preventing conflicts between different versions.
• Easy management: NVM provides simple commands to install, uninstall, and manage Node.js versions, making it easy to maintain your development environment.

Installing NVM

Step 1: Check for prerequisites

Before installing NVM, ensure that you have the following prerequisites installed on your system:

• A Unix-based operating system (Linux, macOS, or WSL on Windows)
• curl or wget command-line tools
• git version control system

Step 2: Download and install NVM

To install NVM, use one of the following methods:

• Using curl:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

• Using wget:

wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.38.0/install.sh | bash

Step 3: Verify the installation

After installing NVM, verify that it’s correctly installed by running the following command:

nvm --version

If NVM is installed properly, you should see the version number printed to the terminal.

Installing Node.js with NVM, including the latest version

To install Node.js with NVM, including the latest version, you can simply use the following command:

nvm install node

This command will automatically install the latest available version of Node.js using NVM. After installation, you can verify the installed version by running node --version. This is particularly useful if you want to ensure that you’re working with the most up-to-date features and improvements in Node.js.

This step is crucial in setting up your Node.js development environment effectively. With NVM, you have the flexibility to install and manage multiple Node.js versions effortlessly, ensuring compatibility with your projects and access to the latest features.

Conclusion

Installing Node.js with NVM offers a convenient way to manage multiple Node.js versions on your system. With NVM, you can easily install, switch between, and manage different Node.js versions, providing flexibility and ease of use for your development projects.
