How do I use FS to make a folder automatically?

Question

I'm trying to use code to read an array and create folders using the name as one of the parameters if that name doesn't exist. I've been using fs to make a simple loop, like so

var streamsRepository = streamsRepositoryFactory(__dirname + '/streams.json');
var obj = streamsRepository.streams[i];
var i;

for(i = 0; i < streamsRepository.streams.length; i++) {
    var obj = streamsRepository.streams[i];

console.log('Folder '+obj.key+' is Created');


    if (!fs.existsSync('../audio/'+obj.key)){
        fs.mkdirSync('../audio/'+obj.key);

    }
}

But every time I keep getting the message.

Folder AAAA is Created
fs.js:796
  return binding.mkdir(pathModule._makeLong(path),
                 ^
Error: ENOENT: no such file or directory, mkdir '../audio/AAAA'

Answer 1

Have a test below

'use strict';
var fs = require('fs');
// fs.mkdirSync('folda'); // success
fs.mkdirSync('/parent-not-exists/folda'); 
// Failed,if parent folder isn't exists,will throw 
// Error: ENOENT, no such file or directory '/parent-not-exists/folda'

solution
use mkdirp,Recursively mkdir, like mkdir -p

var mkdirp = require('mkdirp');

mkdirp('/tmp/foo/bar/baz', function (err) {
    if (err) console.error(err)
    else console.log('pow!')
});
