SERVER SIDE CODE

var multer  = require('multer');
var mkdirp = require('mkdirp');

var storage = multer.diskStorage({
  destination: function (req, file, cb) {
    //var code = JSON.parse(req.body.model).empCode;
    var dest = 'public/uploads/';
    mkdirp(dest, function (err) {
        if (err) cb(err, dest);
        else cb(null, dest);
    });
  },
  filename: function (req, file, cb) {
    cb(null, Date.now()+'-'+file.originalname);
  }
});

var upload = multer({ storage: storage });

router.post('/upload', upload.any(), function(req , res){
    console.log(req.body);
    res.send(req.files);
});
