How to store a file with file extension with multer?

Question

Managed to store my files in a folder but they store without the file extension.

Does any one know how would I store the file with file extension?

Answer 1

I am doing like this

var multer  = require('multer');

var storage = multer.diskStorage({
  destination: function (req, file, cb) {
    cb(null, './public/uploads/img/')
  },
  filename: function (req, file, cb) {
    let ext = file.originalname.substring(file.originalname.lastIndexOf('.'), file.originalname.length);
    cb(null, Date.now() + ext);
  }
})

var upload = multer({ storage: storage }).single('eventimage');
