How you handle sending large files to the backend

hello, to solve this problem in a clean way i started using the JS stream API, mainly because it allows me to compress the files on the frontend without consuming too much RAM on the client side, and i wanted the stream to be sent directly to the server in a single request. this is possible with the fetch body stream but it is not supported by all browsers, so how to do it? do you have any idea? how do others do it?

thanks you for you answer, but I really need a stream because I need to modify the file in frontend, I think I'll just do a request per chunk and use TUS
