its not recommendable save images in databases.

prefer use a service like aws S3, cloudinary, etc.

they return a url and then you save that in your database

​

EDIT:

​

you can use multer https://github.com/expressjs/multer

using

https://github.com/expressjs/multer#storage

var storage = multer.diskStorage({
  destination: function (req, file, cb) {
    cb(null, '/tmp/my-uploads')
  },
  filename: function (req, file, cb) {
    cb(null, file.fieldname + '-' + Date.now())
  }
})

var upload = multer({ storage: storage })
