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() is being deprecated, 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()andfs.open(). Just open the file and handle the error when it's not there.
Install
$ npm install path-exists
Usage
// 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.
