Renaming an uploaded file using Multer doesn't work (Express.js)

Question

I\'m trying to upload a file from a HTML form using Express.js and Multer. I\'ve managed to save the file to the desired location (a folder named uploads).

File has structure like this:

{
"fieldname": "avatar",
"originalname": "somefile.pdf",
"encoding": "7bit",
"mimetype": "application/pdf",
"destination": "./uploads",
"filename": "36db44e11b83f4513188f649ff445a2f",
"path": "uploads\\36db44e11b83f4513188f649ff445a2f",
"size": 1277191

}

The next example saves file with it's original name an extension and not with the strange name like it is by default. (Instead of "file.originalname" you can save it as you want)

var storage = multer.diskStorage({
  destination: function (req, file, cb) {
    cb(null, './uploads') //Destination folder
  },
  filename: function (req, file, cb) {
    cb(null, file.originalname) //File name after saving
  }
})

var upload = multer({ storage: storage })
