Originally, I was using a <code>multipart/form-data</code> request to upload the data + files directly to our backend, which would then upload them to S3.</p> <p>This approach has a couple of main disadvantages:</p> <ul> <li><a href="https://devcenter.heroku.com/articles/request-timeout">Heroku timeouts</a> will abort the request if it takes longer than 30s (can happen if uploading lots of, or big files)</li> <li>it increases the load on your backend</li> </ul> <p>This post will be specifically talking about AWS S3 but <a href="https://cloud.google.com/storage/docs/access-control/signed-urls">GCP has a Signed URLs</a> feature too.</p>
