@nilan if I want to modify a image (Crop it in a node function) each time a new file gets uploaded to the file api, what would the recommended approach be? Should I use a server side subscription, custom mutation resolver or a transform argument? Also, what would I use to do the actual upload? should I send a form data http request with base64 encoded image or what?

could you please describe your situation in the Forum: https://www.graph.cool/forum/?

will do
