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

The file extension can be dynamic. here is the solution

const path = require('path'); // path for cut the file extension
const storage = multer.diskStorage({
    destination: function (req, file, cb) {
      cb(null, 'uploads')
    },
    filename: function (req, file, cb) {
      cb(null, 'upload_at_' + Date.now() + path.extname(file.originalname))
    }
  })
