nvm-info

A small CLI that shows how much space each nvm-installed Node version takes, plus what global packages live under it.

Quick start

Run it once:

npx nvm-info@latest -y

Or install globally:

npm i -g nvm-info
nvm-info

How it works

nvm-info scans your $NVM_DIR/versions/node directory. For each installed Node.js version it:

1. Calculates total disk usage
2. Reads global packages from lib/node_modules
3. Renders a sortable table in the terminal

Requirements

• Node.js >= 18
• nvm installed and configured
• NVM_DIR available in your shell

Typical NVM_DIR setup:

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"

Install from source

git clone https://github.com/this-self/nvm-info.git
cd nvm-info
npm install
npm run build
npm link

Development

npm install
npm run dev
npm run dev:watch
npm run build
npm run format
