I recently tried to connect my Yew frontend app to an actix-web SSE server I use to send events to the page. I tried different approaches and crates like EventSource from “web_sys”, “sse_client” and “gloo_net” but none of them worked.
Sometimes I got CORS errors but now I only get a connection error by the Browser.
For a while the Browser console also said, my callback function got either dropped or was called recursively.
