Recursive directory creation using `fs.mkdirSync()`. Recreates directory tree in series.

nodejs_fs_mkdirsync_recursive.js

var fs = require('fs');

/**
 * Splits whole path into segments and checks each segment for existence and recreates directory tree from the bottom.
 * If since some segment tree doesn't exist it will be created in series.
 * Existing directories will be skipped.
 * @param {String} directory
 */
function mkdirSyncRecursive(directory) {
    var path = directory.replace(/\/$/, '').split('/');

    for (var i = 1; i <= path.length; i++) {
        var segment = path.slice(0, i).join('/');
        !fs.existsSync(segment) ? fs.mkdirSync(segment) : null ;
    }
}

Quick fix for absolute paths:

function mkdirSyncRecursive(directory) {
    var path = directory.replace(/\/$/, '').split('/');
    for (var i = 1; i <= path.length; i++) {
        var segment = path.slice(0, i).join('/');
        segment.length > 0 && !fs.existsSync(segment) ? fs.mkdirSync(segment) : null ;
    }
};
