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         


        

Answer 1

This version works better on Windows than the top answer because it understands both / and path.sep so that forward slashes work on Windows as they should. Supports absolute and relative paths (relative to the process.cwd).

/**
 * Creates a folder and if necessary, parent folders also. Returns true
 * if any folders were created. Understands both '/' and path.sep as 
 * path separators. Doesn't try to create folders that already exist,
 * which could cause a permissions error. Gracefully handles the race 
 * condition if two processes are creating a folder. Throws on error.
 * @param targetDir Name of folder to create
 */
export function mkdirSyncRecursive(targetDir) {
  if (!fs.existsSync(targetDir)) {
    for (var i = targetDir.length-2; i >= 0; i--) {
      if (targetDir.charAt(i) == '/' || targetDir.charAt(i) == path.sep) {
        mkdirSyncRecursive(targetDir.slice(0, i));
        break;
      }
    }
    try {
      fs.mkdirSync(targetDir);
      return true;
    } catch (err) {
      if (err.code !== 'EEXIST') throw err;
    }
  }
  return false;
}
