Node.js official docs provide this example:
path.dirname('/foo/bar/baz/asdf/quux');
// Returns: '/foo/bar/baz/asdf'
However, I actually want 'asdf' instead of full path '/foo/bar/baz/asdf'.
Despite some string manipulation, what is the best way, or is there any official API I can directly get that piece of string?
You can use path.basename() on the directory path returned by path.dirname() as shown below. This method returns the last part of the given path.
const path = require('path');
const dirPath = path.dirname('/foo/bar/baz/asdf/quux');
console.log(path.basename(dirPath))
Offical API or module will also do a string manipulation, it's pretty simple:
path.dirname('/foo/bar/baz/asdf/quux').split("/").pop(); // asdf
For all platforms:
path.dirname('/foo/bar/baz/asdf/quux').split(/\/|\\/).pop(); // asdf
path.basename() as your solution won't catch platform specific differences in the presentation of file paths. For example, your code may fail on Windows as the path separator is `\` on this platform.I believe this simple line of code should give you the desired result.
path.basename(path.dirname("/foo/bar/baz/asdf/quux"))
