What are the purposes and differences between these two modules in Node.js?
fs module is for actually operating on files, directories and volumes (assuming you have already built an appropriate path for the target). The
path module is for manipulating paths which you may then use with the
fs module since many
fs methods accept a path as an argument.
fs module contains functions for manipulating files such as:
fs.readFile() fs.mkdir() fs.open() fs.stat()
path module contains functions for manipulating file paths such as:
path.join() path.normalize() path.extname() path.parse()
You can read the entire list of functions in each module yourself:
The descriptions should be pretty obvious what they do.
Does one depend on the other?
Probably not. The
fs module assumes you already have a valid path that can be passed right on through to the OS. The
path module only builds or parses paths, it doesn't actually do operations on files.
It would be very common to use the two together. For example, you might use the
path module to construct a path which you then pass to an
fs module function.
