nodejs express fs iterating files into array or object failing

Question

So Im trying to use the nodejs express FS module to iterate a directory in my app, store each filename in an array, which I can pass to my express view and iterate through the l

fs.readdir is asynchronous (as with many operations in node.js). This means that the console.log line is going to run before readdir has a chance to call the function passed to it.

You need to either:

Put the console.log line within the callback function given to readdir, i.e:

fs.readdir('./myfiles/', function (err, files) { if (err) throw err;
  files.forEach( function (file) {
    myfiles.push(file);
  });
  console.log(myfiles);
});

Or simply perform some action with each file inside the forEach.
