How to Install Node.js LTS Using NVM

If you are a JavaScript developer or just entering the world of Node.js development, you have probably heard about different versions of Node.js and how compatibility can be an issue in projects different. Node Version Manager (NVM) is an essential tool for anyone who needs to manage multiple versions of Node.js with ease.

What is NVM?

Node Version Manager (NVM) is a tool that allows you to install, manage and switch between different versions of Node.js in your development environment. This is especially useful when you work on projects that require specific versions of Node.js or when you want to test your code on newer versions.

Advantages of using NVM:

1. Easy Version Management: NVM makes the process of installing and switching between different Node.js versions easier, allowing you to quickly adapt to project needs.
2. Environment Isolation: Each project can have its own version of Node.js, avoiding conflicts between projects that require different versions of Node.js.
3. Compatibility Testing: With NVM, you can easily test your code on multiple versions of Node.js to ensure compatibility.
4. Simple Setup: NVM is easy to install and configure, making it an indispensable tool for developers of all experience levels.

Installing NVM

Before installing Node.js using NVM, you need to install NVM itself. Follow the steps below to configure NVM on your system.

Step 1: Install NVM

1. Download the NVM installation script using cURL or wget.
   

   # Usando cURL
   curl -o- <https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh> | bash
   
   # Usando wget
   wget -qO- <https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh> | bash
   
   

2. Reload your shell (or restart your terminal) for the changes to take effect:
   

   source ~/.bashrc   # Para bash
   source ~/.zshrc    # Para zsh
   source ~/.profile  # Para outros
   
   

3. Check if NVM was installed correctly:
   

   nvm --version
   
   

   You should see the version of NVM installed.

Installing Node.js LTS with NVM

Now that you have NVM installed, you can use it to install LTS versions of Node.js.

Install LTS 16 version

1. Install Node.js version 16:
   

   nvm install 16
   
   

2. Set version 16 as the default:
   

   nvm alias default 16
   
   

Install LTS 18 version

1. Install Node.js version 18:
   

   nvm install 18
   
   

2. Set version 18 as the default:
   

   nvm alias default 18
   
   

Install LTS 20 version

1. Install Node.js version 20:
   

   nvm install 20
   
   

2. Set version 20 as the default:
   

   nvm alias default 20
   
   

Switching Between Node.js Versions

With NVM, switching between different versions of Node.js is easy. You can use the nvm use command to specify the version you want to use:

nvm use 16   # Usar a versão 16
nvm use 18   # Usar a versão 18
nvm use 20   # Usar a versão 20
