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.
$ npm install path-exists
// foo.js
const pathExists = require('path-exists');
(async () => {
console.log(await pathExists('foo.js'));
//=> true
})();
Returns a Promise<boolean>
of whether the path exists.
Returns a boolean
of whether the path exists.
