|  | # path-exists [](https://travis-ci.org/sindresorhus/path-exists)
 | ||
|  | 
 | ||
|  | > Check if a path exists
 | ||
|  | 
 | ||
|  | NOTE: `fs.existsSync` has been un-deprecated in Node.js since 6.8.0. If you only need to check synchronously, this module is not needed. | ||
|  | 
 | ||
|  | While [`fs.exists()`](https://nodejs.org/api/fs.html#fs_fs_exists_path_callback) is being [deprecated](https://github.com/iojs/io.js/issues/103), there's still a genuine use-case of being able to check if a path exists for other purposes than doing IO with it. | ||
|  | 
 | ||
|  | Never use this before handling a file though: | ||
|  | 
 | ||
|  | > In particular, checking if a file exists before opening it is an anti-pattern that leaves you vulnerable to race conditions: another process may remove the file between the calls to `fs.exists()` and `fs.open()`. Just open the file and handle the error when it's not there.
 | ||
|  | 
 | ||
|  | 
 | ||
|  | ## Install
 | ||
|  | 
 | ||
|  | ``` | ||
|  | $ npm install path-exists | ||
|  | ``` | ||
|  | 
 | ||
|  | 
 | ||
|  | ## Usage
 | ||
|  | 
 | ||
|  | ```js | ||
|  | // foo.js | ||
|  | const pathExists = require('path-exists'); | ||
|  | 
 | ||
|  | (async () => { | ||
|  | 	console.log(await pathExists('foo.js')); | ||
|  | 	//=> true | ||
|  | })(); | ||
|  | ``` | ||
|  | 
 | ||
|  | 
 | ||
|  | ## API
 | ||
|  | 
 | ||
|  | ### pathExists(path)
 | ||
|  | 
 | ||
|  | Returns a `Promise<boolean>` of whether the path exists. | ||
|  | 
 | ||
|  | ### pathExists.sync(path)
 | ||
|  | 
 | ||
|  | Returns a `boolean` of whether the path exists. | ||
