Transferring large files

[manorit2001]

Hi, I couldn't find anything related to sending files across python-socket-io. Is there some method to share large binary files across the client and server?

The Socket.IO protocol does not have anything specific to send files, but you can load the file contents and send them as a regular event, or if you want to do something fancy, you can also piece the data into smaller chunks and send the pieces, which may allow you to display a progress update.

oh okay

I was actually trying this, but for large files the socket gets disconnected when trying to emit. Is there some flag or something which allows it to automatically break a large transmission to smaller chunks and send it? it might be a helpful feature ig which can allow bigger transmission if required

As I said, there is nothing specific to sending large files, the protocol is really better suited to small payloads and low latency, not to do file transfers. In terms of performance you there is really no advantage versus doing a standard HTTP upload.

If you want to transfer a file in chunks you have to implement the chunk splitting and joining yourself.

okay, thank you for the information. I am closing the issue
