Great guide, thanks a lot, it's very usefull !
Looks like I'm not able to use SSE while using Next.js ... I think has something to do with a proxy rewrite + compression, such a shame

Do you think using SSE is better approach than ... flask-socket-io ? Or am I misunderstanding how differently both approaches can be used? For example let's say I have a backend which also is communicating with Hardware (Camera, PLC or something) and then I'm doing some kind of processing with the given data from the hardware and then I want to update UI from the server side. Should I be using multiple while loops with Threads + Queue mechanisms (so while loops wouldn't eat CPU time) or I should use Sockets for such thing ? Sorry for the long question and thank you for the video ! <3

Hi, do you know how to make this work cross origin? We are struggling with that 😅
