nodejs - recursively search directory for file type or extension

node.js

 var searchRecursive = function(dir, pattern) {
      var results = [];    
      fs.readdirSync(dir).forEach(function (dirInner) {
        // Obtain absolute path
        dirInner = path.resolve(dir, dirInner); 
        var stat = fs.statSync(dirInner);    
        // If path is a directory, scan it and combine results
        if (stat.isDirectory()) {
          results = results.concat(searchRecursive(dirInner, pattern));
        } 
        if (stat.isFile() && dirInner.endsWith(pattern)) {
          results.push(dirInner);
        }
      });    
      return results;
    };

    var files = searchRecursive(config.app.publicPath, '.scss');
