Prefer pnpm

Overview

Always use pnpm instead of npm for package management operations.

When to Use

This skill applies when:

• Installing packages or dependencies
• Adding new packages to a project
• Running package manager commands
• Setting up a new project with dependencies

Core Rule

Instead of	Use
npm install	pnpm install
npm add <pkg>	pnpm add <pkg>
npm install <pkg>	pnpm add <pkg>
npm install -D <pkg>	pnpm add -D <pkg>
npm run <script>	pnpm run <script> or pnpm <script>
npm init	pnpm init
npm ci	pnpm install --frozen-lockfile
yarn add <pkg>	pnpm add <pkg>
yarn add -D <pkg>	pnpm add -D <pkg>
yarn install	pnpm install
yarn run <script>	pnpm run <script>

Quick Reference

# Install all dependencies
pnpm install

# Add a package
pnpm add express

# Add dev dependency
pnpm add -D typescript

# Run a script
pnpm dev
pnpm build

# Initialize new project
pnpm init

Notes

• If a project has package-lock.json but no pnpm-lock.yaml, still use pnpm (it will create the lock file)
• pnpm is faster and more disk-efficient than npm
• pnpm uses a content-addressable store, avoiding duplicate packages
