How to store a file with file extension with multer?

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?

Solution

  • From the docs: "Multer will not append any file extension for you, your function should return a filename complete with an file extension."

    Here's how you can add the extension:

    var multer = require('multer');

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

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

    I would recommend using the mimetype property to determine the extension. For example:

    filename: function (req, file, cb) {
  console.log(file.mimetype); //Will return something like: image/jpeg
