Potential Issue with destination Parameter Type in Multer Custom Storage #1278

function MyCustomStorage (opts) {
  this.getDestination = (opts.destination || getDestination)
}
function MyCustomStorage (opts) {
  this.getDestination = (opts.destination || getDestination)
}

MyCustomStorage.prototype._handleFile = function _handleFile (req, file, cb) {
  this.getDestination(req, file, function (err, path) {
    if (err) return cb(err)

    var outStream = fs.createWriteStream(path)

    file.stream.pipe(outStream)
    outStream.on('error', cb)
    outStream.on('finish', function () {
      cb(null, {
        path: path,
        size: outStream.bytesWritten
      })
    })
  })
