This course is your complete guide to working efficiently with Node Package Manager (npm)—the essential tool in every JavaScript developer’s toolkit.
Start with a solid foundation in managing dependencies, learning how to install, update, audit, and organize third-party libraries for reliability and maintainability. You’ll gain a deep understanding of package.json, semantic versioning, and lockfiles to keep your projects in sync across environments.
From there, we’ll explore npm scripts and automation, showing how to streamline your workflow by creating reusable commands for builds, tests, and custom developer tasks. You’ll also learn how to chain and conditionally run scripts, making your automation smarter and more efficient.
In the project optimization and configuration section, discover how to enhance performance and reduce project size by pruning, deduping, caching, and customizing your .npmrc files. These best practices help ensure your apps run smoothly in development and production.
One of the most empowering aspects of npm is the ability to create and publish your own packages. You’ll walk through the process of creating scoped modules, managing versioning, writing good README documentation, and publishing securely to the npm registry—whether publicly or privately.
Â
The course concludes with advanced use cases and troubleshooting. Learn how to resolve dependency conflicts, use npm link for local development, explore monorepos with npm workspaces, and debug common issues using npm logs and audit tools.
