+# path-exists [![Build Status](https://travis-ci.org/sindresorhus/path-exists.svg?branch=master)](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
+var pathExists = require('path-exists');
+
+pathExists('foo.js').then(function (exists) {
+	console.log(exists);
+	//=> true
+});
+```
+
+
+## API
+
+### pathExists(path)
+
+Returns a promise that resolves to a boolean of whether the path exists.
+
+### pathExists.sync(path)
+
+Returns a boolean of whether the path exists.
