title: Meteor - Excel File Upload without storing file on db
body: <p>I would like the user to be able to upload a file through a file input and the client would send the file to the server and the server would parse the file without storing it in the database, is this possible?</p>
  
  <p>Something like this:</p>
  
  <pre><code>    'change input': function(e, t) {
          let file = e.target.files[0];
          let extension = file.name.split(".").pop();
          if (['xlsb', 'xls', 'xlsx'].indexOf(extension) &lt; 0) {
            Notify.show("error", `Invalid file extension`);
            return false;
          } else {
            Meteor.call("upload.factual.achievements", file, function(err, res){
              if(err){
                Notify.show("error", `There was an error : ${error.reason}.`);
              } else {
  ...
              }
            });
  
          }
        }
  </code></pre>
