You know.... I slept on this. Multer already has options.onFileUploadData
, which emits the event for data. You have the chunks here but these chunks aren't saved to file. When I added the option.inMemory last night, it also includes a new file.buffer property. Within onFileUploadData(file, data), file.buffer would contain the data chunk plus any preceding chunks, whereas the data param would be that single chunk. Hope that helps.

Multer's files are the completely assembled file (all chunks combined).
Multer uses busboy for parsing html multipart data. In busboy, an event is not emitted for chunks of files. An event is emitted for having uploaded the entire file. See busboy code, lines 189 - 205. According to the node docs, FileStream does support the data event, which will return the chunks you need.
You could post an issue on busboy and see if they might emit the chunk event but beyond that I'm not sure what to suggest. At the multer level, we could take the emitted chunk and write it to file. Is this all you'd need? If so, I think there's hope... but this is where my knowledge quickly thins: you'll need a way to figure out if the incoming data started in the middle of the file upload or if it was just beginning. (chuck mgmt process?) If you can step through the logic to implement this, maybe someone reading could take a stab at it?
Sorry, I have no real good answers for you. But maybe someone else will have more insight or know of other resources to do this.

The onFileUpload* functions now include req
and res
. That doesn't give you minute control over file chunks but is a step closer. Now you can get a socket.io instance attached to your req or res session and report back to the client upload progress. Again, it's not allowing for chunked memory management on the server but will create a more responsive app for the client.
