Yeah, we do a lot of similar work, but we use either a download handler or a temporary file system with expiration policy to generate the download (csv/pdf/etc) server-side. We do have one app that that could benefit from your approach though where we parse a user-provided CSV in javascript, let them manipulate, but then we are pushing that data to the server for file generation to retrieve the modified version of their original CSV data. I'll be considering a rework on that since there's literally no reason for it to ever go to the server if we use your approach.
