I can't upload files from html form on my node/express app

Posted on July 4, 2017

Hello,

I’m just running a simple Node.js/Express application on a droplet and I can’t upload files to the designated folder from a html form on a page of the application.

I’m just running the application with ‘node app.js’ and it runs on port 3000. I could be wrong but I don’t think Apache is involved here, is that correct?

I’ve chmod 777’d the folder to where the files go but every time I try and upload a file the application hangs for a few seconds and then gets “Killed”.

The upload location is ‘app_root/public/uploads’

I am aware of the security issues here, I just want to do a little bit of live testing, I don’t plan to the have the application up for long.

Thanks for any help! Jonathan

Ok, It’s actually Jimp that is cause the problem here. I was trying to resize the file before saving, and it’s failing somewhere here:

function savePhoto(photo, userId) {
    var timestamp = Math.round((new Date()).getTime() / 1000);
    var photoname = userId + - + timestamp + '.png';
    jimp.read(photo.data, function (err, photo) {
        if (err) throw err;
        photo.resize(400, jimp.AUTO)            
            .quality(70)
            .write("public/uploads/" + photoname);
    });
    return photoname;
}

whereas if i use ‘express-fileupload’ to save the file, it works fine:

function savePhoto(photo, userId) {
    var timestamp = Math.round((new Date()).getTime() / 1000);
    var photoname = userId + - + timestamp + '.png';
    photo.mv('public/uploads/' + photoname, function(err) {
        if (err) throw err;
    });
    return photoname;
}

Thanks for any help!
