JavaScript Package Manager: NPM vs PNPM vs Yarn

JavaScript development offers three prominent package managers: NPM, PNPM, and Yarn. NPM, bundled with Node.js, is a widely used default with a vast package repository and security auditing. PNPM, a performant NPM alternative, optimizes disk space and installation speed using a linking mechanism. Yarn, developed by Facebook, also focuses on speed through a global cache and parallel downloads. Each manager boasts distinct benefits and trade-offs regarding performance, disk usage, and features like concurrent installations or offline mode. NPM excels in its established ecosystem and security auditing but uses more disk space. PNPM offers superior disk efficiency and faster installations but lacks built-in security auditing. Yarn provides fast performance, deterministic resolution, and workspace support, though its lockfile can be larger. Basic commands for installation, removal, updates, and more are available for all three. Project structures are similar, with variations in lockfile names and how dependencies are managed. The best choice among NPM, PNPM, and Yarn depends on project-specific needs for speed, disk space, and desired features.
