package.json

package.json is a JSON configuration file used in Node.js projects to define metadata, dependencies, scripts, and other project settings. It serves as the manifest for npm (Node Package Manager) packages, specifying details like name, version, author, and required packages. This file is essential for managing project dependencies, automating tasks, and ensuring consistent environments across development and deployment.

Also known as: npm package.json, node package.json, package json, pkg.json, npm config

Why learn package.json?

Developers should learn and use package.json because it is fundamental for any Node.js or JavaScript project using npm, enabling dependency management, version control, and script automation. It is crucial for specifying project metadata, managing third-party libraries, and configuring build processes, making it indispensable for modern web development, backend services, and tooling workflows.
