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

# Monorepo
npm init -w packages/my-lib

Core Concepts

package.json

Manifest file. Scripts, dependencies, metadata.

package-lock.json

Locks dependency tree for reproducible builds. Commit this.

Workspaces

Native monorepo support. npm install installs dependencies for root and all nested packages.

Best Practices (2025)

Do:

  • Use npm ci: For CI/CD pipelines. Faster and strict (fails if lockfile doesn't match).
  • Audit: npm audit to find vulnerabilities.
  • Use Scopes: @my-org/my-pkg to avoid name collisions.

Don't:

  • Don't mix managers: Don't use yarn in a repo with package-lock.json.
