I'm working on a Rails application that uploads large files (~300mb). Is there a way to incorporate a progress indicator without relying on a specific HTML5 uploader or installing the nginx server module? Can this be achieved simply with the standard file upload field?
Thanks in advance!
My knowledge is limited to JS/AJAX, where the DOM gets refreshed upon a successful upload callback.
Another option is exploring the configuration of express/Node.js for handling streamed uploads and utilizing AJAX to update the DOM (in this scenario, your Node.js service would operate separately from Rails - communication with it would be done through JSON).
In the case of utilizing pure AJAX, I recommend implementing a dedicated call to retrieve the current upload status (/upload/status/upload_id). You can set up a timer to check progress every 2 seconds, for example.
Within your server-side setup, consider having a separate thread responsible for overseeing the upload process and providing updates on its progress.
