# locate-path [![Build Status](https://travis-ci.org/sindresorhus/locate-path.svg?branch=master)](https://travis-ci.org/sindresorhus/locate-path)

> Get the first path that exists on disk of multiple paths


## Install

```
$ npm install locate-path
```


## Usage

Here we find the first file that exists on disk, in array order.

```js
const locatePath = require('locate-path');

const files = [
	'unicorn.png',
	'rainbow.png', // Only this one actually exists on disk
	'pony.png'
];

(async () => {
	console(await locatePath(files));
	//=> 'rainbow'
})();
```
