how to filter and batch delete files on node.js

gistfile1.js

var DIST_FOLDER = '../deploy/';

// ---

var _minimatch = require('minimatch'),
    _wrench = require('wrench'),
    _fs = require('fs'),
    _path = require('path');

function purgeDeploy(){
    var files = _wrench.readdirSyncRecursive(DIST_FOLDER);
    files = filterFiles(files, [
        '{**/,}.svn{/**,}'
    ]);
    files.forEach(function(path){
        path = _path.join(DIST_FOLDER, path);
        //don't remove folders since it will cause SVN conflict
        if( _fs.statSync(path).isFile() ) {
            _fs.unlinkSync(path);
        }
    });
}

function filterFiles(files, excludes) {
    var globOpts = {
        matchBase: true,
        dot : true
    };
    excludes = excludes.map(function(val){
        //minimatch currently have a bug with star globs (https://github.com/isaacs/minimatch/issues/5)
        //so use makeRe instead
        return _minimatch.makeRe(val, globOpts);
    });

    return files.filter(function(filePath){
        return ! excludes.some(function(glob){
            return glob.test(filePath);
        });
    });
}

maybe I should check if folder is empty and if so delete it as well (since it won't cause SVN conflicts)
