How to prevent displaying the file until onAfterUpload has finished

[jankapunkt]

I am uploading sound files and transform all file formats on the server with ffmpeg to mp3 for best support.

However, I am replacing the original file completely. Basically my onAfterUpload is structured in the following steps (way too much code to show here):

• probe file using ffprobe
• transform file to mp3 using ffmpeg
• get stats from the new mp3 file
• updated collection doc entry and versions.original with mp3 file's path, size, extension etc.
• move file to gridFS
• delete the uploaded file

Until this process finishes I don't want to preview the file but display something like "processing file....".

The issue is, the client does not know, when onAfterUpload has finished. I could, of course simply add a flag to the document like processFinished: false and subscribe to it, so it automatically updates.

However, I wanted to know, if there is any mechanism already builtin that implements such behavior.

Hello @jankapunkt ,

I'd recommend setting meta.isReady or meta.isFullyUploaded, since meta is the only object with open schema if you follow all guidelines and schema validation.

@jankapunkt the same way we set the error, like meta.processingError

@dr-dimitru thank you I am doing that now. I was just thinking, if there was already some builtin mechanism so I don't need additional collection access. However, it's doing its job and overhead seems neglectible.
