- # path-exists [](https://travis-ci.org/sindresorhus/path-exists)
- > Check if a path exists
- Because [`fs.exists()`](https://nodejs.org/api/fs.html#fs_fs_exists_path_callback) is being [deprecated](https://github.com/iojs/io.js/issues/103), but 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 --save path-exists
- ```
- ## Usage
- ```js
- // foo.js
- const pathExists = require('path-exists');
- pathExists('foo.js').then(exists => {
- console.log(exists);
- //=> true
- });
- ```
- ## API
- ### pathExists(path)
- Returns a promise for a boolean of whether the path exists.
- ### pathExists.sync(path)
- Returns a boolean of whether the path exists.
