> 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
|
|
|
|
**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');
|
|
```

|
|
|
* The computer name is always preceded by a double backward-slash (`\\`).
|
|
* UNC paths cannot contain a drive letter (such as `D:`)
