Master npm and JavaScript package management from the ground up. Learn package.json configuration, dependency management, semantic versioning, npm scripts, and security best practices. Essential knowledge for any JavaScript developer.
Every JavaScript project starts with a single command, `npm install`, yet what actually happens inside that node_modules folder remains a mystery to most developers. This free npm & package management course pulls back the curtain, taking you from your very first package.json file to confident, day-to-day mastery of the tooling that powers nearly every modern JavaScript and Node.js application. Instead of memorizing commands by rote, you'll understand the system underneath them: how dependencies resolve, why version numbers matter, and how to keep your projects fast, stable, and secure.
Across this npm & package management tutorial, you'll learn package.json configuration from the ground up, manage production and development dependencies cleanly, and decode semantic versioning so you always know what `^`, `~`, and exact version pins really do. You'll write and chain npm scripts to automate builds and tests, audit your projects for vulnerabilities, and apply security best practices that protect both your code and your users. By the end, you'll be able to learn package workflows that scale from a weekend side project to a large production codebase.
This is a practical, beginner-friendly programming course built for anyone who writes JavaScript, students, self-taught coders, and working developers who want to fill the gaps in their fundamentals. No prior experience with package managers is assumed; if you can open a terminal, you're ready to start. The entire course is 100% free, with no paywalls or trials, and you'll earn a free certificate of completion to mark your progress. Sign up, work through it at your own pace, and turn npm from a black box into a tool you genuinely control.
