nvm

nvm stands for Node Version Manager. It is a tool that allows you to manage multiple versions of Node.js on a single machine.

With nvm, anyone can easily install, switch between, and manage different versions of Node.js and npm (Node Package Manager).

Install

macOS / Linux

Open a terminal and execute the command below.

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.3/install.sh | bash

Then need to add nvm on shell profile. To do so, the following line have to add in .bashrc, .bash_profile, or .zshrc file.

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

Then restart terminal or run the following command.

source ~/.bashrc

for bashrc

source ~/.zshrc

for zshrc

Windows

Download and install nvm-windows

Use

Install node

nvm install x

Replace x by a node version.

Like install node.js 18

nvm install 18

Like install node.js 20

nvm install 20

Listing all node version

nvm ls

Output will be like below.

       v18.20.4
->     v20.15.1
         system
default -> 18 (-> v18.20.4)
iojs -> N/A (default)
unstable -> N/A (default)
node -> stable (-> v20.15.1) (default)
stable -> 20.15 (-> v20.15.1) (default)
lts/* -> lts/iron (-> v20.15.1)
lts/argon -> v4.9.1 (-> N/A)
lts/boron -> v6.17.1 (-> N/A)
lts/carbon -> v8.17.0 (-> N/A)
lts/dubnium -> v10.24.1 (-> N/A)
lts/erbium -> v12.22.12 (-> N/A)
lts/fermium -> v14.21.3 (-> N/A)
lts/gallium -> v16.20.2 (-> N/A)
lts/hydrogen -> v18.20.4
lts/iron -> v20.15.1

This means node.js v20.15.1 is used here.

Switch

Consider you want to switch node.js v18 from current version.

nvm use 18

Set Default node.js Version

nvm alias default 20

This will set default node.js version in shell.

Verify Version

node -v
