How to check if my images are saved on Heroku server

Question

So I am trying to allow the users to upload images to my server to show it on a website later. I am using Multer like this:

var uploadLogo = multer({
    dest: './public/images/logos/'
});
.post(uploadLogo.single('logo'), (req, res, next) => {
    var r = req.body;
    account.register(
        new account({
                'employer': {
                    'logo': req.file,
                }
            },
            r.password
        ))
});

The interesting thing is, this works on the local version, but images disappear after a while on the online version.

How can I check if the images exist on the server? Or should I maybe use a 3rd party API like imgur to handle this?

Answer 1

The free Heroku dynos are stopped after some time of inactivity, and all the locally stored data is removed. Consider persisting the images in something like AWS S3.
