Node.js

Node.js is a JavaScript runtime built on Chrome's V8 JavaScript engine.

INFO

Here we will install nvm to use multiple Node.js version.

You can install basic Node.js package but with NVM, you can change Node.js version when you want. Check last version on NVM GitHub and change it if you want latest.

Here, the NVM version is 0.39 and Node.js version is 20.16.0 LTS.

Installation

Download NVM

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.7/install.sh | bash

Add this into ~/.zshrc

INFO

If NVM is already in ~/.zshrc, you can skip this step.

vim ~/.zshrc

export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm

Reload ~/.zshrc

source ~/.zshrc

Usage

Now you can use nvm, install Node.js v20.16.0 and config nvm to use it.

List all Node.js versions

nvm ls-remote

Install Node.js v20.16.0

nvm install 20.16.0

Use Node.js v20.16.0

nvm use 20.16.0

Set v20.16.0 as default

nvm alias default 20.16.0

nvm use default

Check Node.js version

nvm ls
node -v

Install another version

If you want to install another version, you can use nvm install command.

nvm install 14.17.0

And to use it

nvm use 14.17.0

Usage with absolute path

If you want to use Node.js with absolute path, you can use nvm which command.

nvm which 20.16.0

/home/user/.nvm/versions/node/v20.16.0/bin/node ./index.js

Errors

If you have an error like nvm: command not found, you can check if nvm is in ~/.zshrc.

cat ~/.zshrc

If it's not there, you can add it.

export NVM_DIR="$([ -z "${XDG_CONFIG_HOME-}" ] && printf %s "${HOME}/.nvm" || printf %s "${XDG_CONFIG_HOME}/nvm")"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
