file.size undefined with multiple files

[Doc999tor]

Why the file.size is undefined:

1. storage.filename callback arguments are based on request content disposition header: filename, content-type etc. In multer().single() middleware the file is already being uploaded and you can have more detailed file stats

https://github.com/expressjs/multer/blob/master/lib/make-middleware.js#L106

      var file = { // initial content disposition header reading
        fieldname: fieldname,
        originalname: filename,
        encoding: encoding,
        mimetype: mimetype
      }

https://github.com/expressjs/multer/blob/master/storage/disk.js#L47

      outStream.on('finish', function () {
        cb(null, {
          destination: destination,
          filename: filename,
          path: finalPath,
          size: outStream.bytesWritten // actual filesize stat from the finished stream
        })
      })

https://github.com/expressjs/multer/blob/master/lib/make-middleware.js#L158

     var fileInfo = extend(file, info) // extending the initial file object with actual file stats

3. For your use case, you can move the db population to later middleware, when the files will already be uploaded and written to disk
