Uploading image to amazon s3 using multer-s3 nodejs

Question

I am trying to upload an image to amazon s3 using multer-s3, but I am getting this error:

TypeError: Expected opts.s3 to be object node

Answer 1

s3 needs to be an object to be passed. According to the docs, the object needs to be like this:

var upload = multer({
  storage: multerS3({
    s3: s3,
    bucket: 'some-bucket',
    metadata: function (req, file, cb) {
      cb(null, {fieldName: file.fieldname});
    },
    key: function (req, file, cb) {
      cb(null, Date.now().toString())
    }
  })
})
