The package.json file in a Node.js project has multiple uses. It defines the project's metadata, like its name, version, and description. It also lists the dependencies and devDependencies required to run or develop the application, as well as scripts for tasks like building, testing, or running the app (and any custom script you’d like to add).
Finally, it ensures reproducible installations by allowing the npm install command to pull consistent dependencies, ensuring you can easily port your project into other systems.
