strip-dirs

strip-dirs

Remove leading directory components from a path, like tar(1)'s --strip-components option

var stripDirs = require('strip-dirs');

stripDirs('foo/bar/baz', 1); //=> 'bar/baz'
stripDirs('foo/bar/baz', 2); //=> 'baz'
stripDirs('foo/bar/baz', 999); //=> 'baz'

Installation

Install with npm. (Make sure you have installed Node)

npm install --save strip-dirs

API

var stripDirs = require('strip-dirs');

stripDirs(path, count [, option])

path: String (A relative path)
count: Number (0, 1, 2, ...)
option: Object
Return: String

It removes directory components from the beginning of the path by count.

var stripDirs = require('strip-dirs');

stripDirs('foo/bar', 1); //=> 'bar'
stripDirs('foo/bar/baz', 2); //=> 'bar'
stripDirs('foo/././/bar/./', 1); //=> 'bar'
stripDirs('foo/bar', 0); //=> 'foo/bar'

stripDirs('/foo/bar', 1) // throw an error because the path is an absolute path

option.narrow

Type: Boolean
Default: false

By default, it keeps the last path component when path components are fewer than the count.

If this option is enabled, it throws an error in such case.

stripDirs('foo/bar/baz', 9999); //=> 'baz'

stripDirs('foo/bar/baz', 9999, {narrow: true}); // throws an error
