> Normalize slashes in a file path to be posix/unix-like forward slashes. Also condenses repeat slashes to a single slash and removes and trailing slashes, unless disabled.

|
|
## Install
|
|
|
|
Install with [npm](https://www.npmjs.com/):
|
|
|
|
```sh
|
|
$ npm install --save normalize-path
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
const normalize = require('normalize-path');
|
|
|
|
console.log(normalize('\\foo\\bar\\baz\\'));
|
|
//=> '/foo/bar/baz'
|
|
```
|
|
|
|
**win32 namespaces**
|
|
|
|
```js
|
|
console.log(normalize('\\\\?\\UNC\\Server01\\user\\docs\\Letter.txt'));
|
|
//=> '//?/UNC/Server01/user/docs/Letter.txt'
|
|
|
|
console.log(normalize('\\\\.\\CdRomX'));
|
|
//=> '//./CdRomX'
|
|
```
|
|
|
|
**Consecutive slashes**
|
|
|
|
Condenses multiple consecutive forward slashes (except for leading slashes in win32 namespaces) to a single slash.
|
|
|
|
```js
|
|
console.log(normalize('.//foo//bar///////baz/'));
|
|
//=> './foo/bar/baz'
|
|
```
|
|
|
|
### Trailing slashes
|
|
|
|
By default trailing slashes are removed. Pass `false` as the last argument to disable this behavior and _**keep** trailing slashes_:
|
|
|
|
```js
|
|
console.log(normalize('foo\\bar\\baz\\', false)); //=> 'foo/bar/baz/'
|
|
console.log(normalize('./foo/bar/baz/', false)); //=> './foo/bar/baz/'
|
|
```
|

## Release history
|
|
|
|
### v3.0
|
|
|
|
No breaking changes in this release.
|
|
|
|
* a check was added to ensure that [win32 namespaces](https://msdn.microsoft.com/library/windows/desktop/aa365247(v=vs.85).aspx#namespaces) are handled properly by win32 `path.parse()` after a path has been normalized by this library.
|
|
* a minor optimization was made to simplify how the trailing separator was handled
