||
|
## Install
|
||
|
|
||
|
```

|
||
|
```
|
||

## 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'
|
||
|
];
|
||
|
|
||
|
locatePath(files).then(foundPath => {
|
||
|
console.log(foundPath);
|
||
|
//=> 'rainbow'
|
||
|
});
|
||
|
```
|
||
|
|
||
|
|
||
