如何从 .net core 或 express 后端获取通知以响应 js 前端？

Question

I'm using fetch() in javascript to fetch data from my .net core backend (will later be replaced with node and express) to my react js front end. With this I can do stuff like http GET and POST, etc. But I need to also be able to get notifications/send messages from the backend when something changes. I assume I need to use something else. What do you recommend? SignalR? Something else?

What ur looking for would be real-time communication

For Node/Express I'd recommend Socket.IO https://socket.io/
