OPTIONS

jQuery File Upload makes an OPTIONS request to the server before starting the uppload to make sure that it can upload to the given server.

app.options('/upload', jfum.optionsHandler.bind(jfum));

POST

app.post('/upload', jfum.postHandler.bind(jfum), function(req, res) {
  // Check if upload failed or was aborted
  if (req.jfum.error) {
    // req.jfum.error

  } else {
    // Here are the uploaded files
    for (var i = 0; i < req.jfum.files.length; i++) {
      var file = req.jfum.files[i];

      // Check if file has errors
      if (file.errors.length > 0) {
        for (var j = 0; i < file.errors.length; i++) {
          // file.errors[j].code
          // file.errors[j].message
        }

      } else {
        // file.field - form field name
        // file.path - full path to file on disk
        // file.name - original file name
        // file.size - file size on disk
