Node.js check if file exists

Question

How do i check the existence of a file?

In the documentation for the module fs there\'s a description of the method fs.exists(path, cal

Answer 1

Well I did it this way, as seen on https://nodejs.org/api/fs.html#fs_fs_access_path_mode_callback

fs.access('./settings', fs.constants.F_OK | fs.constants.R_OK | fs.constants.W_OK, function(err){
  console.log(err ? 'no access or dir doesnt exist' : 'R/W ok');

  if(err && err.code === 'ENOENT'){
    fs.mkdir('settings');
  }
});

Is there any problem with this?
