Can't connect to S3, using Cloudcube Addon on Heroku Express/Node App


I am in the middle of testing out my Heroku setup and connections, and added CloudCube to my Express/Node app to use it for storage.

I wanted to connect to enable file storage through my live Heroku app, I attached an addon to my Heroku app called Cloudcube, which grants me a cube inside their S3 bucket with environment access credentials. Pretty sure I used credentials properly.

I have been trying to get this connection to work for hours.

What I tried so far:

I did npm install on aws-sdk, multer, and multer-s3, required them, then used it as advised, but switching out my credentials, and added a "dest" key in the upload function setup to point to my sub-cube & desired directory in the Cloudcube bucket, this is my best guess of how to do it:

aws.config.update({
  secretAccessKey: process.env.CLOUDCUBE_SECRET_ACCESS_KEY,
  accessKeyId: process.env.CLOUDCUBE_ACCESS_KEY_ID,
  region: "eu-west-1"
});

const s3 = new aws.S3();

const upload = multer({
  dest: "yutqk2v0mx6h/public/",
  storage: multerS3({
    s3: s3,
    bucket: "cloud-cube-eu",
    key: function(req, file, cb) {
      console.log(file);
      cb(null, file.originalname); //use Date.now() for unique file keys
    }
  })
});

I am testing this using the test routes explained in the previously shared stackoverflow post, as follows:

//open in browser to see upload form
app.get('/', function (req, res) {
  res.sendFile(__dirname + '/index.html');
});

//use by upload form
app.post('/upload', upload.array('upl',1), function (req, res, next) {
  res.send("Uploaded!");
});

I tried many different variations of this with no success.

You can see my full backend testing repo here: https://github.com/malkhuzayyim/hasad-backend

It has some extra code from previous testing on setup, everything else works just the static file uploads fail.

Upon attempting to upload, i get these logs on my heroku logs dashboard:

Multer S3 Documentation can be seen here: https://www.npmjs.com/package/multer-s3

You can also see the Cloudcube documentation here: https://devcenter.heroku.com/articles/cloudcube

My api is live on https://hasad-backend.herokuapp.com/

I really need to get this to work, as I plan on using this setup for future projects and am using this course as a proxy to get myself familiar with this setup.

Any advice on best approaches to link Heroku Express API to Cloudcube?

I would really appreciate the help.

Thank you very much.

Best,

Solution

  • I figured it out, everything was in place, i was just parsing the destination of the path incorrectly, which made cloudcube reject my upload, since my "storage cube" is technically a sub-directory in their S3 bucket.

    Mistake was:

    const upload = multer({
      dest: "yutqk2v0mx6h/public/",
      storage: multerS3({
        s3: s3,
        bucket: "cloud-cube-eu",
        key: function(req, file, cb) {
          console.log(file);
          cb(null, file.originalname);
            }
        })
    });
    

    Where as the correct way to parse my file storage directory was to pre-pend it to my file-name inside the key function of multerS3:

    const upload = multer({
      storage: multerS3({
        s3: s3,
        bucket: "cloud-cube-eu",
        key: function(req, file, cb) {
          console.log(file);
          const myFileName = "yutqk2v0mx6h/public/" + Date.now();
          console.log(myFileName);
          cb(null, myFileName);
        }
      })
    });
    

    A response from cloudcube's email support hinted at the solution, as soon as I tried this it worked right away.

    Thanks for taking a look Scott, I'll leave this here in case anyone else goes through a Heroku/S3 setup.

    Best,

    MK
