npm

npm is the default package manager for Node.js, providing dependency resolution, workspace management, security auditing, and publishing workflows for JavaScript ecosystems.

When to Use

• JavaScript / TypeScript Package Management: Installing, publishing, and managing npm modules and dependencies.
• Multi-Package Monorepos (npm Workspaces): Coordinating interconnected local packages with unified dependency resolution.
• Supply Chain Security & Provenance: Publishing packages with cryptographically verifiable build provenance.
• Vulnerability Auditing & Dependency Overrides: Resolving transitively vulnerable packages using overrides.

Quick Start

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