Understanding Package JSON , Demystifying Package JSON files: learn what every field means and how to use each one of them.
Course Description
If you have worked with JavaScript or Node projects, you’ve definitely seen the package JSON file. It’s the heart of every project, such as defining dependencies, scripts, metadata, and configuration settings that control how your project behaves. Yet, many developers only scratch the surface, using the same few fields (name, version, scripts, dependencies) and ignoring the rest.
This course is designed to change that.
In this course, you’ll take a deep dive into one of the most essential files in the JavaScript ecosystem. Whether you’re just starting out or you’ve been using Node for a while, this course will help you truly understand what every part of the file does and how to use it to your advantage.
You’ll explore fields like exports, engines, files, peerDependencies, type, man, bin, and more — with clear examples, explanations, and real-world use cases. By the end of this course, you’ll be able to read, write, and debug these package JSON files with confidence.
Whether you’re building web apps, CLIs, or publishing NPM packages, mastering Package JSON files will give you the foundation to work smarter and ship faster.
So, grab your laptop and get ready. It’s time to unlock the full potential of your Node project configuration!
