Multer s3 Filename

Question

I'm using multer s3 to upload images from my node.js app to my amazon bucket. I'm using the date together with the original filename to create the new filename; however, when I try to display the new filename it just displays as undefined. This is my code:

    var upload = multer({
  storage: multerS3({
    s3: s3,
    bucket: 'imagebucket',
    acl: 'public-read',
    metadata: function (req, file, cb) {
      cb(null, Object.assign({}, req.body));
    },
    key: function (req, file, cb) {
        console.log(file);
        cb(null, Date.now()+file.originalname);
    }
  })
})

app.post('/upload', upload.single('upload'), function(req, res, next) {
  res.send('Successfully uploaded ' + req.file.length + ' files!')
})

Any help would be welcomed.

Exactly where do you try to display filename? In your code, it seems you only try to display file object that passed down to the multer — reyalsnogard, Jun 03 '18 at 10:36

It looks like you are not passing a string to the key function

Please try this:

key: function (req, file, cb) {
    console.log(file);
    cb(null, `${Date.now().toString()}${file.originalname}`);
}
