> Returns true if a filepath is a windows UNC file path.
|
||
|
|
|
||
|
|
## Install
|
||
|
|
|
||
|
|
Install with [npm](https://www.npmjs.com/):
|
||
|
|
|
||
|
|
```sh
|
||
|
|
$ npm install --save is-unc-path
|
||
|
|
```
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
```js
|
||
|
|
var isUncPath = require('is-unc-path');
|
||
|
|
```
|
||
|
|
|
||
|
|
**true**
|
||
|
|
|
||
|
|
Returns true for windows UNC paths:
|
||
|
|
|
||
|
|
```js
|
||
|
|
isUncPath('\\/foo/bar');
|
||
|
|
isUncPath('\\\\foo/bar');
|
||
|
|
isUncPath('\\\\foo\\admin$');
|
||
|
|
isUncPath('\\\\foo\\admin$\\system32');
|
||
|
|
isUncPath('\\\\foo\\temp');
|
||
|
|
isUncPath('\\\\/foo/bar');
|
||
|
|
isUncPath('\\\\\\/foo/bar');
|
||
|
|
```
|
||
|
|
|
||
|
|
**false**
|
||
|
|
|
||
|
|
Returns false for non-UNC paths:
|
||
|
|
|
||
|
|
```js
|
||
|
|
isUncPath('/foo/bar');
|
||
|
|
isUncPath('/');
|
||
|
|
isUncPath('/foo');
|
||
|
|
isUncPath('/foo/');
|
||
|
|
isUncPath('c:');
|
||
|
|
isUncPath('c:.');
|
||
|
|
isUncPath('c:./');
|
||
|
|
isUncPath('c:./file');
|
||
|
|
isUncPath('c:/');
|
||
|
|
isUncPath('c:/file');
|
||
|
|
```
|
||
|
|
|
||
|
|
**Customization**
|
||
|
|
|
||
|
|
Use `.source` to use the regex as a component of another regex:
|
||
|
|
|
||
|
|
```js
|
||
|
|
var myRegex = new RegExp(isUncPath.source + 'foo');
|
||
|
|
```
|
||
|
|
|
||
|
|
**[Rules for UNC paths](http://resources.esri.com/help/9.3/ArcGISDesktop/com/Gp_ToolRef/sharing_tools_and_toolboxes/pathnames_explained_colon_absolute_relative_unc_and_url.htm)**
|
||
|
|
|
||
|
|
* The computer name is always preceded by a double backward-slash (`\\`).
|
||
|
|
* UNC paths cannot contain a drive letter (such as `D:`)
