How to create full path with node's fs.mkdirSync?

Question

I\'m trying to create a full path if it doesn\'t exist.

The code looks like this:

var fs = require(\'fs\');
if (!fs.existsSync(newDest)) fs.mkdirSync

I had issues with the recursive option of fs.mkdir so I made a function that does the following:

1. Creates a list of all directories, starting with the final target dir and working up to the root parent.
2. Creates a new list of needed directories for the mkdir function to work

3. Makes each directory needed, including the final

   function createDirectoryIfNotExistsRecursive(dirname) {
       return new Promise((resolve, reject) => {
          const fs = require('fs');
   
          var slash = '/';
   
          // backward slashes for windows
          if(require('os').platform() === 'win32') {
             slash = '\\';
          }
          // initialize directories with final directory
          var directories_backwards = [dirname];
          var minimize_dir = dirname;
          while (minimize_dir = minimize_dir.substring(0, minimize_dir.lastIndexOf(slash))) {
             directories_backwards.push(minimize_dir);
          }
   
          var directories_needed = [];
   
          //stop on first directory found
          for(const d in directories_backwards) {
             if(!(fs.existsSync(directories_backwards[d]))) {
                directories_needed.push(directories_backwards[d]);
             } else {
                break;
             }
          }
   
          //no directories missing
          if(!directories_needed.length) {
             return resolve();
          }
   
          // make all directories in ascending order
          var directories_forwards = directories_needed.reverse();
   
          for(const d in directories_forwards) {
             fs.mkdirSync(directories_forwards[d]);
          }
   
          return resolve();
       });
    }
