Generate the minimal skeleton for a new node.js module/package.

For example, to create a module in the current working directory:

$ npx module

To create a module in another directory, specify a relative or absolute path:

$ npx module foo

The --system flag can be provided to control whether the module system is ESM (the default if flag not specified) or CommonJS:

$ npx module foo --system esm

$ npx module foo --system cjs

And the --identifier flag can be provided to control whether the module system is identified by file extension (the default if flag not specified), package.json type field, or implicitly from code syntax:

$ npx module foo --system esm --identifier file-ext

$ npx module foo --system cjs --identifier package-type

$ npx module foo --system esm --identifier syntax

To understand these flags better, see Determining module system in the node.js docs.
