Check if a path exists
Because fs.exists()
is being deprecated, 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()
andfs.open()
. Just open the file and handle the error when it's not there.
$ npm install --save path-exists
// foo.js
const pathExists = require('path-exists');
pathExists('foo.js').then(exists => {
console.log(exists);
//=> true
});
Returns a promise for a boolean of whether the path exists.
Returns a boolean of whether the path exists.
