Which file lists all your application's required node packages?1 pointpackage.jsonnode.jsonnpm.jsonpkg.json

The file that lists all your application's required Node.js packages is package.json. This file is crucial when developing Node.js applications as it contains metadata relevant to the project, including the names and versions of dependencies needed to run the application.

Explanation:

1. package.json: This is the standard file used in Node.js projects that specifies the dependencies needed for the application along with a range of other configurations. Developers can manage dependencies, scripts, and various configurations all within this single file.

2. node.json, npm.json, and pkg.json: These files do not exist as standard files in typical Node.js project structures. While developers may create files with these names, they do not hold significance in the context of Node.js application dependencies.

In summary, whenever you initialize a Node.js project or add dependencies, the package.json file is updated to include all necessary package information, making it essential for package management in Node.js applications.
