Remove leading directory components from a path, like [tar(1)](http://linuxcommand.org/man_pages/tar1.html)'s `--strip-components` option
|
|
|
|
```javascript
|
|
const stripDirs = require('strip-dirs');
|
|
|
|
stripDirs('foo/bar/baz', 1); //=> 'bar/baz'
|
|
stripDirs('foo/bar/baz', 2); //=> 'baz'
|
|
stripDirs('foo/bar/baz', 999); //=> 'baz'
|
|
```
|
|
|
|
## Installation
|
|
|
|
[Use npm](https://docs.npmjs.com/cli/install).
|
|
|
|
```
|
|
npm install --save strip-dirs
|
|
```
|
|
|
|
## API
|
|
|
|
```javascript
|
|
const 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*.
|
|
|
|
```javascript
|
|
const 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
|
|
```
|
|
|
|
If you want to remove all directory components certainly, use [`path.basename`](https://nodejs.org/api/path.html#path_path_basename_path_ext) instead of this module.
|
|
|
|
#### option.disallowOverflow
|
|
|
|
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 this situation.
|
|
|
|
```javascript
|
|
stripDirs('foo/bar/baz', 9999); //=> 'baz'
|
|
|
|
stripDirs('foo/bar/baz', 9999, {disallowOverflow: true}); // throws an range error
|
|
```
