So, take the example that you have that saves to a local machine and change that part to save to ftp server.

You're going to need a javascript component, like JSZip, to compress the file on the client side before your client-side code can upload the file to the FTP server.

Once there, I'd probably have a service running that checks that upload folder for ZIP files. Once there, this service would have to move the file to a pre-stage folder, unzip the content to a target staging folder, verify the content for good content if applicable, move it to an appropriate production folder and clear out the staging and pre-staging folders, then notify the web site that the content is ready.

But that's just me.

You could skip the FTP server entirely and just upload the zipped file directly to the web server and do all the steps above synchronously and return the unzipped PDF or some error but if the file is big enough the client may just time out before you send the first byte of your response back to the client.
