Large file upload with WebSocket

Question

I\'m trying to upload large files (at least 500MB, preferably up to a few GB) using the WebSocket API. The problem is that I can\'t figure out how to write \"send this slice

Answer 1

Use web workers for large files processing instead doing it in main thread and upload chunks of file data using file.slice().

This article helps you to handle large files in workers. change XHR send to Websocket in main thread.

//Messages from worker
function onmessage(blobOrFile) {
 ws.send(blobOrFile);
}

//construct file on server side based on blob or chunk information.
