Busboy and GridFS won't save file to filesystem

Question

When the following POST API is called, it should save the file to the file system. However, the file is not being saved. I can see the file in the console, but can't save/write it. I have the following code:

router.post('/notes', function(req, res, next) {
  var gfsstream, startFileWrite, endFileWriteTime;
  var busboy = new Busboy({ headers: req.headers });

  busboy.on('file', function(fieldname, file, filename, encoding, mimetype) {
    startFileWrite = new Date().getTime();
    console.log('File [' + fieldname + ']: filename: ' + filename);

    gfsstream = gfs.createWriteStream('/uploads');
    file.on('data', function(data) {
      gfsstream.write(data);
    });
    file.on('end', function() {
      gfsstream.end();
      req.pipe(gfsstream);
    });
    gfsstream.on('close', function (file) {
      // do something with `file`
     endFileWrite = new Date().getTime();
     console.log('File [' + fieldname + '] Finished');
     console.log("Time needed: " + (endFileWrite - startFileWrite) + " ms");
    });
  });

  busboy.on('error', function(err) {
    console.error(err);
    res.sendStatus(500, 'ERROR', err);
  });

  busboy.on('finish', function end() {
    res.sendStatus(200);
  });
  req.pipe(busboy);
});

req.pipe(gfsstream) might be the issue here, but I am not sure what is preventing the file from being saved.

Answer 1

Just do file.pipe(gfsstream) and use the finish event instead of the close event:

busboy.on('file', function(fieldname, file, filename, encoding, mimetype) {
  startFileWrite = new Date().getTime();
  console.log('File [' + fieldname + ']: filename: ' + filename);

  gfsstream = gfs.createWriteStream('/uploads');
  file.pipe(gfsstream).on('finish', function() {
    endFileWrite = new Date().getTime();
    console.log('File [' + fieldname + '] Finished');
    console.log("Time needed: " + (endFileWrite - startFileWrite) + " ms");
  });
});
