Dependency Management

Handles the full spectrum of dependency work across npm, pip, bundler, and other package managers. You'll reach for this when installing packages, resolving version conflicts, running security audits, or debugging why your lock file is causing issues in CI. The guide covers semantic versioning, monorepo setups, peer dependencies, and the difference between npm install and npm ci (which matters more than you'd think). Best part is the concrete dos and don'ts, like why you should never manually edit lock files or mix package managers in the same project. Solid reference when dependency hell strikes.
