npm commands

Which command creates the package.json file interactively?

	yes	no
npm install	[ ]	[x]
npm init	[x]	[ ]
npm package.json	[ ]	[x]

If you already have a package.json file, it'll read that first, and default to the options in there.

How do you install a package and save it as a dependency in the package.json file?

	yes	no
npm install <package name> --save	[x]	[ ]
npm install <package name> --s	[ ]	[x]
npm install <package name> -S	[x]	[ ]

When uninstalling a package "save" flag will also update the dependency to package.json file: npm uninstall <package name> --save

How do you list packages?

	yes	no
npm list	[x]	[ ]
npm ls	[x]	[ ]
npm -l	[ ]	[x]
npm list -g	[x]	[ ]

Adding the "g" flag after "list" or "ls" will show you globally installed packages: npm list -g or npm ls -g
