npm

npm is the default package manager for Node.js. v11 (2025) introduces strict publishing rules and npx caching improvements.

When to Use

• Default: It comes with Node. Zero friction.
• Compatibility: The standard package-lock.json is supported everywhere.
• Publishing: npm publish is the canonical way to share JS code.

Quick Start

npm init -y
npm install lodash
npm install --save-dev jest
