Delete several files in node.js

Question

What is the best way to delete several files in node.js?

function deleteFiles(files, callback){
    ...
}

var files = [\'file1.js\', \'file2.jpg\', \'file3.css\         


        

Answer 1

This deletes the files in an array and runs the callback once only after all files have been deleted.

function deleteFiles(files, callback){
   if (files.length==0) callback();
   else {
      var f = files.pop();
      fs.unlink(f, function(err){
         if (err) callback(err);
         else {
            console.log(f + ' deleted.');
            deleteFiles(files, callback);
         }
      });
   }
}
